Sweety bought enough bottles of sports drink to fill a big cooler for the skateboard team. It toom 25. 5 bottles to fill the cooler and each bottle contained 1. 8 liters. There are 46.8 litres in cooler.

To find the number of liters in the cooler, we need to multiply the number of bottles by the amount of liquid in each bottle. Given that it took 25.5 bottles to fill the cooler and each bottle contains 1.8 liters, we can find the total amount of liquid in the cooler by multiplying these two values together.

First, let's round the number of bottles to the nearest whole number, which is 26.

To calculate the total amount of liquid in the cooler, we multiply the number of bottles by the amount of liquid in each bottle:

26 bottles * 1.8 liters/bottle = 46.8 liters

Therefore, there are 46.8 liters in the cooler.

To find the daily mileage for which the Ultimo charge is twice the Primo charge, we can set up an equation and solve for the unknown value.

Let's start by defining some variables:
- Let x be the daily mileage.
- The Primo car rental agency charges $45 per day plus $0.40 per mile, so the Primo charge can be expressed as 45 + 0.40x.
- The Ultimo car rental agency charges $26 per day plus $0.85 per mile, so the Ultimo charge can be expressed as 26 + 0.85x.
According to the question, we need to find the value of x for which the Ultimo charge is twice the Primo charge. Mathematically, we can write this as:
26 + 0.85x = 2(45 + 0.40x)
Now, let's solve this equation step-by-step:
1. Distribute the 2 to the terms inside the parentheses on the right side of the equation:
26 + 0.85x = 90 + 0.80x
2. Move all the x terms to one side of the equation and all the constant terms to the other side:
0.85x - 0.80x = 90 - 26
3. Simplify and solve for x:
0.05x = 64
x = 64 / 0.05
x = 1280
Therefore, the daily mileage for which the Ultimo charge is twice the Primo charge is 1280 miles.

The IVP has a unique solution defined on some interval I with 0 € I.

here is the  solution to show that there is some interval I with 0 € I such that the IVP has a unique solution defined on I:

The given differential equation is y = y³ + 2.

The initial condition is y(0) = 1.

Let's first show that the differential equation is locally solvable. This means that for any fixed point x0, there is an interval I around x0 such that the IVP has a unique solution defined on I.

To show this, we need to show that the differential equation is differentiable and that the derivative is continuous at x0.

The differential equation is differentiable at x0 because the derivative of y³ + 2 is 3y².

The derivative of 3y² is continuous at x0 because y² is continuous at x0.

Therefore, the differential equation is locally solvable.

Now, we need to show that the IVP has a unique solution defined on some interval I with 0 € I.

To show this, we need to show that the solution does not blow up as x approaches infinity.

We can show this by using the fact that y³ + 2 is bounded above by 2.

This means that the solution cannot grow too large as x approaches infinity.

Therefore, the IVP has a unique solution defined on some interval I with 0 € I.

To prove the equalities given, we need to show that each set on the left-hand side is equal to the corresponding set on the right-hand side.

B(R) represents the set of all open intervals in the real numbers R. This set includes intervals of the form (a, b) where a and b are real numbers. The notation o({...}) denotes the set of all open sets created by the elements inside the curly braces.

The set {[a, b): a·b ∈ R} consists of closed intervals [a, b) where the product of a and b is a real number. By allowing a·b to be any real number, the set includes intervals that span the entire real number line.

Similarly, the set {(a, b]: a·b ∈ R} consists of closed intervals (a, b] where the product of a and b is a real number. Again, the set includes intervals that span the entire real number line.

The sets {(a, ∞): a ∈ R} and {[a, ∞): a ∈ R} represent intervals with one endpoint being infinity. In the case of (a, ∞), the interval is open on the left side, while [a, ∞) is closed on the left side. Both sets cover the positive half of the real number line.

Let a, b, c, and d be real numbers. Given that ac = 1, db + c is undefined, and abc = d, the following must be true: a = 0 or c = 0.

This is option option A.

Since ac = 1, we can say that either a or c has to be unequal to zero. We don't know anything about db + c yet, but we do know that abc = d.

Substitute d = abc into db + c = d, and you'll get b (ac) + c = abc.

Since ac = 1, we can write it as b + c = abc. Since abc is not zero, b + c cannot be zero.

Therefore, either b or c cannot be zero because the sum of two non-zero numbers cannot be zero. As a result, we may conclude that a = 0 or c = 0.

Answer:

(a) Range: y > 2

(b) Domain: All reals

Step-by-step explanation:

The range of a function is the set of all possible output values (y-values).

A horizontal asymptote is a horizontal line that the curve gets infinitely close to, but never touches. It is displayed as a horizontal dashed line. Therefore, the horizontal asymptote of the graphed exponential function is y = 2.

Since there is a horizontal asymptote at y = 2, and the curve appears to be always above this line, it indicates that the range of the function is all y-values greater than 2.

[tex]\hrulefill[/tex]

The domain of a function is the set of all possible input values (x-values).

As the x-values of graphed exponential function appear to be unrestricted, the domain of the function is all real numbers.

The equation that relates x and y is:

y = 100x + 500

In this equation, y is the total amount of money in the checking account (in dollars), and x is the number of weeks Deshaun has been adding money. The coefficient of x, 100, represents the rate at which Deshaun is adding money to the account. So, each week, Deshaun adds $100 to the account. The y-intercept, 500, represents the initial amount of money in the account. So, when Deshaun starts adding money to the account, the account already has $500 in it.

To see how this equation works, let's say that Deshaun has been adding money to the account for 5 weeks. In this case, x = 5. Substituting this value into the equation, we get:

y = 100 * 5 + 500 = 1000

This means that after 5 weeks, the total amount of money in the account is $1000.

The function g(x) = f(x - h) + k represents a translation of the original function f(x) by a horizontal shift of h units to the right and a vertical shift of k units upwards.

In this translation:

- The term (x - h) inside the function represents the horizontal shift. The value of h determines the amount and direction of the shift. If h is positive, the function shifts h units to the right, and if h is negative, the function shifts h units to the left.

- The term k outside the function represents the vertical shift. The value of k determines the amount and direction of the shift. If k is positive, the function shifts k units upwards, and if k is negative, the function shifts k units downwards.

To find the value of the fourth number, we can use the concept of the mean.

The mean of a set of numbers is calculated by adding up all the numbers and then dividing the sum by the total number of values.

Given that the mean of four numbers is 10 and three of the numbers are 10, 14, and 8, we can substitute these values into the mean formula and solve for the fourth number.

Let's denote the fourth number as "x".

Mean = (Sum of all numbers) / (Total number of values)

10 = (10 + 14 + 8 + x) / 4

Now, let's solve the equation for "x".

Multiply both sides of the equation by 4 to eliminate the denominator:

(a) To determine if matrix A is nonsingular, we need to find its rank. The rank of a matrix is the maximum number of linearly independent rows or columns. By performing row operations or using other methods such as Gaussian elimination, we can determine that matrix A has a rank of 2. Since the rank is equal to the number of rows or columns of the matrix, which is 2 in this case, we can conclude that A is nonsingular.

(b) To calculate the inverse of matrix A using the Gauss-Jordan method, we can augment A with the identity matrix of the same size and then apply row operations to transform the left part into the identity matrix.

The expression `cos⁻¹(-2.35)` is undefined.

What is the inverse cosine function?

The inverse cosine function, denoted as `cos⁻¹(x)` or `arccos(x)`, is the inverse function of the cosine function.

The inverse cosine function, cos⁻¹(x), is only defined for values of x between -1 and 1, inclusive. The range of the cosine function is [-1, 1], so any value outside of this range will not have a corresponding inverse cosine value.

In this case, -2.35 is outside the valid range for the input of the inverse cosine function.

The result of `cos⁻¹(x)` is the angle θ such that `cos(θ) = x` and `0 ≤ θ ≤ π`.

When `x < -1` or `x > 1`, `cos⁻¹(x)` is undefined.

(a) The possible limits of the sequence (xn) are 0 (when p = 1/3) and 3/(1 - p) (when p ≠ 1/3).

(b) When 0 < x0 ≤ 3, the sequence is bounded above by 3 and is monotone increasing.

(c) When x0 > 3, the sequence is bounded below by 3 and is monotone decreasing.

(d) For all choices of x0 > 0, the limit of the sequence (xn) exists. The limit is 0 when p = 1/3, and it is 3/(1 - p) when p ≠ 1/3.

(a) The possible limits of the sequence (xn) can be found by analyzing the recursive formula. Let's assume that the sequence converges to a limit L. Taking the limit as n approaches infinity, we have:

L = 3(p L + 1 - 1).

Simplifying the equation, we get:

L = 3pL + 3 - 3.

Rearranging terms, we have:

3pL = L.

This equation has two possible solutions:

1. L = 0, when p = 1/3.

2. L = 3/(1 - p), when p ≠ 1/3.

Therefore, the possible limits of the sequence (xn) are 0 (when p = 1/3) and 3/(1 - p) (when p ≠ 1/3).

(b) Let's consider the case when 0 < x0 ≤ 3. We need to show that 3 is an upper bound of the sequence and that the sequence is monotone increasing.

First, we'll prove by induction that xn ≤ 3 for all n.

For the base case, when n = 1, we have x1 = 3(p x0 + 1 - 1). Since 0 < x0 ≤ 3, it follows that x1 ≤ 3.

Assuming xn ≤ 3 for some n, we have:

xn+1 = 3(p xn + 1 - 1) ≤ 3(p(3) + 1 - 1) = 3p + 3 - 3p = 3.

So, by induction, we have xn ≤ 3 for all n, proving that 3 is an upper bound of the sequence.

To show that the sequence is monotone increasing, we'll prove by induction that xn+1 ≥ xn for all n.

For the base case, when n = 1, we have x2 = 3(p x1 + 1 - 1) = 3(p(3p x0 + 1 - 1) + 1 - 1) = 3(p^2 x0 + p) ≥ 3(x0) = x1, since 0 < p ≤ 1.

Assuming xn+1 ≥ xn for some n, we have:

xn+2 = 3(p xn+1 + 1 - 1) ≥ 3(p xn + 1 - 1) = xn+1.

So, by induction, we have xn+1 ≥ xn for all n, proving that the sequence is monotone increasing when 0 < x0 ≤ 3.

(c) Now, let's consider the case when x0 > 3. We'll show that the sequence is monotone decreasing and bounded below by 3.

To prove that the sequence is monotone decreasing, we'll prove by induction that xn+1 ≤ xn for all n.

For the base case, when n = 1, we have x2 = 3(p x1 + 1 - 1) = 3(p(3p x0 + 1 - 1) + 1 - 1) = 3(p^2 x0 + p) ≤ 3(x0) = x1, since p ≤ 1.

Assuming xn+1 ≤ xn for some n, we have:

xn+2 = 3(p xn+1 + 1 - 1) ≤ 3(p xn + 1 - 1) = xn+1.

So, by induction, we have xn+1 ≤ xn for all n, proving that the sequence is monotone decreasing when x0 > 3.

To show that the sequence is bounded below by 3, we can observe that for any n, xn ≥ 3.

(d) From part (b), we know that when 0 < x0 ≤ 3, the sequence is monotone increasing and bounded above by 3. From part (c), we know that when x0 > 3, the sequence is monotone decreasing and bounded below by 3.

Since the sequence is either monotone increasing or monotone decreasing and bounded above and below by 3, it must converge. Thus, the limit of the sequence (xn) exists for all choices of x0 > 0.

To compute the limit, we need to consider the possible cases:

1. When p = 1/3, the limit is L = 0.

2. When p ≠ 1/3, the limit is L = 3/(1 - p).

Therefore, the limit of the sequence (xn) is 0 when p = 1/3, and it is 3/(1 - p) when p ≠ 1/3.

The possible limits are given by L = 1/(3p), where p is a constant. The specific value of p depends on the initial value x0 chosen.

(a) To determine the possible limits of the sequence (xn), let's assume the sequence converges and find the limit L. Taking the limit of both sides of the recursive definition, we have:

lim(xn) = lim[3(p xn−1 + 1 − 1)]

Assuming the limit exists, we can replace xn with L:

L = 3(pL + 1 − 1)

Simplifying:

L = 3pL

Dividing both sides by L (assuming L ≠ 0), we get:

1 = 3p

Therefore, the possible limits of the sequence (xn) are given by L = 1/(3p), where p is a constant.

(b) Let's consider the case when 0 < x0 ≤ 3. We will show that 3 is an upper bound of the sequence and that the sequence is monotone increasing.

First, we can observe that since x0 > 0 and p > 0, then 3(p xn−1 + 1 − 1) > 0 for all n. This implies that xn > 0 for all n.

Now, we will prove by induction that xn ≤ 3 for all n.

Base case: For n = 1, we have x1 = 3(p x0 + 1 − 1). Since 0 < x0 ≤ 3, we have 0 < px0 + 1 ≤ 3p + 1 ≤ 3. Therefore, x1 ≤ 3.

Inductive step: Assume xn ≤ 3 for some positive integer k. We will show that xn+1 ≤ 3.

xn+1 = 3(p xn + 1 − 1)

≤ 3(p * 3 + 1 − 1) [Using the inductive hypothesis, xn ≤ 3]

≤ 3(p * 3 + 1) [Since p > 0 and 1 ≤ 3]

≤ 3(p * 3 + 1 + p) [Adding p to both sides]

= 3(4p)

= 12p

Since p is a positive constant, we have 12p ≤ 3 for all p. Therefore, xn+1 ≤ 3.

By induction, we have proved that xn ≤ 3 for all n, which implies that 3 is an upper bound of the sequence (xn). Additionally, since xn ≤ xn+1 for all n, the sequence is monotone increasing.

(c) Now let's consider the case when x0 > 3. We will show that the sequence is monotone decreasing and bounded below by 3.

Similar to part (b), we observe that x0 > 0 and p > 0, which implies that xn > 0 for all n.

We will prove by induction that xn ≥ 3 for all n.

Base case: For n = 1, we have x1 = 3(p x0 + 1 − 1). Since x0 > 3, we have p x0 + 1 − 1 > p * 3 + 1 − 1 = 3p. Therefore, x1 ≥ 3.

Inductive step: Assume xn ≥ 3 for some positive integer k. We will show that xn+1 ≥ 3.

xn+1 = 3(p xn + 1 − 1)

≥ 3(p * 3 − 1) [Using the inductive hypothesis, xn ≥ 3]

≥ 3(2p + 1) [Since p > 0]

≥ 3(2p) [2p + 1 > 2p]

= 6p

Since p is a positive constant, we have 6p ≥ 3 for all p. Therefore, xn+1 ≥ 3.

By induction, we have proved that xn ≥ 3 for all n, which implies that the sequence (xn) is bounded below by 3. Additionally, since xn ≥ xn+1 for all n, the sequence is monotone decreasing.

(d) Based on parts (b) and (c), we have shown that for all choices of x0 > 0, the sequence (xn) is either monotone increasing and bounded above by 3 (when 0 < x0 ≤ 3) or monotone decreasing and bounded below by 3 (when x0 > 3).

According to the Monotone Convergence Theorem, a bounded monotonic sequence must converge. Therefore, regardless of the value of x0, the sequence (xn) converges.

To compute the limit, we can use the result from part (a), where the possible limits are given by L = 1/(3p), where p is a constant. The specific value of p depends on the initial value x0 chosen.

To make "ACC" a true statement, we need to remove the elements 1, 2, and 3 from set A, leaving only the positive odd numbers.

(a) The set A x B is the set of all ordered pairs where the first element comes from set A and the second element comes from set B. Therefore, A x B = {(1, red), (1, blue), (2, red), (2, blue), (3, red), (3, blue)}.

(b) The set DNA represents the intersection of sets D and A, which means it includes elements that are common to both sets. DNA = {2}.

The set DB represents the intersection of sets D and B. DB = {blue}.

The set (DA)u(DnB) represents the union of sets DA and DB. (DA)u(DnB) = {2, blue}.

(c) The two disjoint sets from the given sets are A and C. There are no common elements between them.

(d) The set C' represents the complement of set C with respect to the universal set S. Since S is the set of all positive whole numbers, the complement of C includes all positive whole numbers that are not positive odd numbers.

Therefore, C' = {n: n is a positive whole number and n is not an odd number}.

(e) A C means that every element in set A is also an element in set C. In this case, A C is not true because set A contains elements 1, 2, and 3, which are not positive odd numbers. To make "ACC" a true statement, we need to remove the elements 1, 2, and 3 from set A, leaving only the positive odd numbers.

Answer:

Step-by-step explanation:

First find all the factors of 48:

1, 2, 3, 4, 6, 8, 12, 16, 24, 48

These are the only values that x can be.  Try them all and see which results in a whole number:

√48/1 = 6.93  not whole

√48/2 = 4.9  not whole

√48/3 = 4  WHOLE

√48/4 = 3.46  not whole

√48/6 = 2.83  not whole

√48/8 = 2.45  not whole

√48/12 = 2  WHOLE

√48/16 = 1.73  not whole

√48/24 = 1.41  not whole

√48/48 = 1  WHOLE

Therefore, there are 3 values of x for which √48/x = whole number.  The numbers are x = 3, 12, 48

Thus, the sum of the sequence 6+11+16+21+...+51 is 256.

Gauss's approach is a method to sum a sequence of numbers. It involves pairing the first and last terms, the second and second-to-last terms, and so on until the sum is determined. The sum of the first and last terms is then added to the sum of the second and second-to-last terms, and so on, to get the total sum.Let's use this approach to find the sum of 6+11+16+21+...+51. To begin, let's pair the first and last terms:6 + 51 = 57The sum of the second and second-to-last terms is:11 + 46 = 57We can continue pairing terms:16 + 41 = 5721 + 36 = 57...As we can see, all the pairs of terms add up to 57. There are 9 terms in this sequence, so we have 9 pairs: 4 full pairs (including the first and last term) and one middle term. The total sum of the sequence is obtained by multiplying the sum of a pair by the number of pairs:total sum = 57 x 4 + 28 = 256.

Answer:

[tex]60cm^{2}[/tex]

Step-by-step explanation:

The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

If we look at this shape, we can split it into 3 separate shapes (shown below)

The top rectangle in blue has a length of 2cm and a width of 10cm. We know the width is 10 because if we were to look at the width of the yellow rectangle and add on the original width you would get:

Now that we know that the length is 2 and the width is 10, we can use the following formula to solve for the area of a rectangle:

(Where l = length and h = height)

Inserting 2 in for our length and 10 for our width:

Therefore, the area of the blue rectangle is [tex]20cm^{2}[/tex].

Looking at the bottom green rectangle, it has the same dimensions as the blue, so it will also have an area of [tex]20cm^{2}[/tex].

The same goes for the yellow rectangle. It has a length of 10 and a width of 2. These are also the same dimensions as before, so we can once again conclude that the area of the yellow rectangle is [tex]20cm^{2}[/tex]

We have 3 rectangles with areas of [tex]20cm^{2}[/tex] each, so we can use either one of these expressions to solve for the entire area:

Or we can use:

Therefore the area of the entire shape is [tex]60cm^{2}[/tex]

Answer:

4.44%

Step-by-step explanation:

%Error = [tex]\frac{E-T}{T}[/tex] x 100

E = experiment

T = Theoretical

E = 86

T = 90

What is the percent error?​

We Take

[tex]\frac{86-90}{90}[/tex] x 100 ≈ 4.44%

So, the percent error is about 4.44%

P(B|A) would be approximately 0.78 or 78% as a proportion rounded to two decimal places.

To calculate the probability P(B|A), we can use Bayes' Theorem, which states:

P(B|A) = (P(A|B) * P(B)) / P(A)

Given the information provided, let's assign the following probabilities:

P(A) = Probability of morning cloud cover > 50% = 0.30

P(B) = Probability of rain in general = 0.26

P(A|B) = Probability of morning cloud cover > 50% given afternoon rain = 0.90

We can now calculate P(B|A):

P(B|A) = (P(A|B) * P(B)) / P(A)

       = (0.90 * 0.26) / 0.30

Calculating this expression:

P(B|A) = 0.234 / 0.30

P(B|A) ≈ 0.78

Therefore, P(B|A) would be approximately 0.78 or 78% as a proportion rounded to two decimal places.

The elements of the splitting field are:

{0, 1, α, β, α+β, αβ, α+αβ, β+αβ, α+β+αβ}

To find the splitting field of the polynomial p(x) = x² + x + 1 in ℤ/(2ℤ)[x], we need to find the field extension over which the polynomial completely factors into linear factors.

Since we are working with ℤ/(2ℤ), the field consists of only two elements, 0 and 1. We can substitute these values into p(x) and check if they are roots:

p(0) = 0² + 0 + 1 = 1 ≠ 0, so 0 is not a root.

p(1) = 1² + 1 + 1 = 3 ≡ 1 (mod 2), so 1 is not a root.

Since neither 0 nor 1 are roots of p(x), the polynomial does not factor into linear factors over ℤ/(2ℤ)[x].

To find the splitting field, we need to extend the field to include the roots of p(x). In this case, the roots are complex numbers, namely:

α = (-1 + √3i)/2

β = (-1 - √3i)/2

The splitting field will include these two roots α and β, as well as all their linear combinations with coefficients in ℤ/(2ℤ).

The elements of the splitting field are:

{0, 1, α, β, α+β, αβ, α+αβ, β+αβ, α+β+αβ}

These elements form the splitting field of p(x) = x² + x + 1 in ℤ/(2ℤ)[x].

The correct interpretation of the point (2, 4) in this context is:

2. After 2 minutes, the depth of the pool is 4 feet.

In the given model y = -2x + 8, the equation represents the relationship between the time in minutes (x) and the depth of the pool in feet (y) after draining. The equation is in the form of a linear function, where the coefficient of x (-2) represents the rate of change of the depth of the pool over time.

To determine the meaning of the point (2, 4) in this context, we need to substitute the value of x as 2 into the equation and solve for y.

When x = 2:

y = -2(2) + 8

y = -4 + 8

y = 4

Therefore, when 2 minutes have passed, the depth of the pool is 4 feet. This means that after 2 minutes of draining, the water level in the pool has decreased to 4 feet.

It is important to note that in this model, the coefficient -2 indicates that the depth of the pool decreases by 2 feet for every minute that passes. As time increases, the depth of the pool will continue to decrease at a constant rate of 2 feet per minute.

The given point (2, 4) provides a specific example that illustrates the relationship between time and the depth of the pool. It confirms that after 2 minutes of draining, the pool's depth is indeed 4 feet.

The normal vector of the desired plane is (6, 0, -12), and a scalar equation for the plane is 6x - 12z + k = 0, where k is a constant that can be determined by substituting the coordinates of one of the given points, such as M(1, 2, 3).

A scalar equation for the plane through points M(1, 2, 3) and N(3, 2, -1) that is perpendicular to the plane with equation 3x + 2y + 6z + 1 = 0 is:

3x + 2y + 6z + k = 0,

where k is a constant to be determined.

To find a plane perpendicular to the given plane, we can use the fact that the normal vector of the desired plane will be parallel to the normal vector of the given plane.

The given plane has a normal vector of (3, 2, 6) since its equation is 3x + 2y + 6z + 1 = 0.

To determine the normal vector of the desired plane, we can calculate the vector between the two given points: MN = N - M = (3 - 1, 2 - 2, -1 - 3) = (2, 0, -4).

Now, we need to find a scalar multiple of (2, 0, -4) that is parallel to (3, 2, 6). By inspection, we can see that if we multiply (2, 0, -4) by 3, we get (6, 0, -12), which is parallel to (3, 2, 6).

The values of the coefficients A and B in the equation y = A e^(-Bx) are A ≈ 289.693 and B ≈ 0.271.

To determine the values of the coefficients A and B in the equation y = A * e^(-Bx) using the method of least squares, we need to minimize the sum of the squared residuals between the predicted values and the actual data points.

Let's denote the given data points as (x_i, y_i), where x_i represents the x-coordinate and y_i represents the corresponding y-coordinate.

Given data points:

(77, 2.4)

(100, 3.4)

(185, 7.0)

(239, 11.1)

(285, 19.6)

To apply the least squares method, we need to transform the equation into a linear form. Taking the natural logarithm of both sides gives us:

ln(y) = ln(A) - Bx

Let's denote ln(y) as Y and ln(A) as C, which gives us:

Y = C - Bx

Now, we can rewrite the equation in a linear form as Y = C + (-Bx).

We can apply the least squares method to find the values of B and C that minimize the sum of the squared residuals.

Using the linear equation Y = C - Bx, we can calculate the values of Y for each data point by taking the natural logarithm of the corresponding y-coordinate:

[tex]Y_1[/tex] = ln(2.4)

[tex]Y_2[/tex] = ln(3.4)

[tex]Y_3[/tex] = ln(7.0)

[tex]Y_4[/tex] = ln(11.1)

[tex]Y_5[/tex] = ln(19.6)

We can also calculate the values of -x for each data point:

-[tex]x_1[/tex] = -77

-[tex]x_2[/tex] = -100

-[tex]x_3[/tex] = -185

-[tex]x_4[/tex] = -239

-[tex]x_5[/tex] = -285

Now, we have a set of linear equations in the form Y = C + (-Bx) that we can solve using the least squares method.

The least squares equations can be written as follows:

ΣY = nC + BΣx

Σ(xY) = CΣx + BΣ(x²)

where Σ represents the sum over all data points and n is the total number of data points.

Substituting the calculated values, we have:

ΣY = ln(2.4) + ln(3.4) + ln(7.0) + ln(11.1) + ln(19.6)

Σ(xY) = (-77)(ln(2.4)) + (-100)(ln(3.4)) + (-185)(ln(7.0)) + (-239)(ln(11.1)) + (-285)(ln(19.6))

Σx = -77 - 100 - 185 - 239 - 285

Σ(x^2) = 77² + 100² + 185² + 239² + 285²

Solving these equations will give us the values of C and B. Once we have C, we can determine A by exponentiating C (A = [tex]e^C[/tex]).

After obtaining the values of A and B, round them to 3 decimal places as specified.

By applying the method of Least Squares to the given data points, the calculated values are A ≈ 289.693 and B ≈ 0.271, rounded to 3 decimal places.
