The range of the exponential function y is [0, 62,150]

In the given function of the exponential function, [tex]y = 62,150 (0.9999)^x[/tex], x is the number of months since the car was purchased.

The initial value of the function is 62,150. The car depreciates over time because the function decreases when the value of x increases. The base of the exponential function is 0.9999 which is less than 1.

The range of the exponential function y based on its equation and the context of the problem is [0, 62,150].The reason for this is because the initial value of the function is 62,150.

This means that the value of y can never be more than 62,150. Also, the base of the exponential function is less than 1 which means that the function decreases over time.

Therefore, the minimum value of the function is 0. Therefore, the range of the exponential function y is [0, 62,150]. Hence, the answer is [0, 62,150].

Step-by-step explanation:

U and V are mutually exclusive events. P(U) = 0.26; P(V) = 0.37. So,

a. P(U AND V) = 0

b. P(U|V) = 0

c. P(U OR V) = P(U) + P(V)

U and V cannot happen at the same time since they are mutually exclusive events. Therefore, the probability of their intersection, P(U AND V), is equal to 0.

Comparably, the conditional probability P(U|V) denotes the likelihood that event U will take place in the event that event V has already happened. U, however, is not possible if V has already happened because U and V are mutually exclusive. Consequently, P(U|V) likewise equals 0.

To find the probability of the union of U and V, P(U OR V), we add the individual probabilities of U and V because they are mutually exclusive. Therefore, P(U OR V) = P(U) + P(V) = 0.26 + 0.37 = 0.63.

Step-by-step explanation:

The probability that a randomly selected grapefruit weighs more than 1.25 pounds is approximately 0.019.

To find the probability that a randomly selected grapefruit weighs more than 1.25 pounds, we need to calculate the area under the normal distribution curve to the right of 1.25 pounds.

First, we calculate the z-score using the formula:

z = (x - μ) / σ,

where

x is the value we're interested in,

μ is the mean, and

σ is the standard deviation.

In this case, x = 1.25, μ = 1, and σ = 0.12.

z = (1.25 - 1) / 0.12 = 2.08

Next, we look up the corresponding area under the standard normal distribution curve for a z-score of 2.08. Using a standard normal distribution table or calculator, we find that the area to the right of 2.08 is approximately 0.019.

Answer:

Step-by-step explanation:

If Brandon buys 2 gifts and the cost of each gift is f, then the cost of the 2 gifts is 2f.... 1

Also if Daniel buys d gifts, the cost of each gift is p, then the cost of d gifts will be "pd ".... 2

If Georgia buys 2 more gifts than Daniel, then the amount of gift bought by daniel will be d+2. If the cost of each gift is z, the cost of (d+2) gifts will be z(d+2) .... 3

If Mr. Jones also decides to buy gifts for his children and the cost of each gift is f, then the total cost of the gift he bought for his children is yf where y is the number of gifts he bought for his children.

The total amount paid by Mr. Jones will be expressed by the summing all the derived function as shown;

2f+dp+z(d+2)+yf

= 2f+yf+ dp+z(d+2)

= 2f+2y+dp+z(d+2)

Hence the algebraic expression for how much money Mr Jones should pay at the gift shop till if he also decides to buy gifts for his children and the cost of each gift is f is expressed as 2f+2y+dp+z(d+2)

Answer:

c. 31(-10) = -310

Step-by-step explanation:

because...........

In other words, everything but -30.

========================================================

Explanation:

Let's solve for x

[tex]-\frac{1}{5}x + 3 \le 7\\\\-\frac{1}{5}x \le 7-3\\\\-\frac{1}{5}x \le 4\\\\x \ge 4*(-5)\\\\x \ge -20\\\\[/tex]

Note how the inequality sign flips when we multiply both sides by the negative number.

Since x can be -20 or larger, this means that the values -20,-10,0,10,20 are all solutions. Only -30 is a non-solution. It might help to draw out a number line to see which values work and don't work.

--------------------------------

An alternative method is to plug each value from the set {-30,-20,-10,0,10,20} into the original inequality and simplifying. If you get a true statement at the end, then the value is a solution.

I'll show an example with x = -30 and x = -20 to show a non-solution and a solution. I'll let you check the others.

So let's start with x = -30

[tex]-\frac{1}{5}x + 3 \le 7\\\\-\frac{1}{5}(-30) + 3 \le 7\\\\6 + 3 \le 7\\\\9 \le 7\\\\[/tex]

The last statement is false because 9 is not 7 or smaller than 7. So that's why x = -30 is not a solution.

Now let's try x = -20

[tex]-\frac{1}{5}x + 3 \le 7\\\\-\frac{1}{5}(-20) + 3 \le 7\\\\4 + 3 \le 7\\\\7 \le 7\\\\[/tex]

This is a true statement since any number is equal to itself.

You should find that x = -10, x = 0, x = 10, and x = 20 lead to true statements.

Yes this is actually correct, labelling numbers gives it a meaning, and also makes it understandable to whoever is reading or solving a problem associated with the number

12+2=3 ordinarily would be false because

12+2=14

but when a label is attached

that is  12 inches + 2 feet= 3 feet

12 inches is  the same as 1 foot

so 1foot+2feet= 3 feet

Step-by-step explanation:

y=–2x

–4=–2(1)

–4=–2 (error)

The absolute maximum value of f(x, y) on D is 0, and the absolute minimum value is -64.

(a) To find the critical points of the function f(x, y) = 4xy^2 - x^2y^2 - xy^3, we need to find the values of x and y where the partial derivatives with respect to x and y are equal to zero.

Taking the partial derivative with respect to x:

∂f/∂x = 4y^2 - 2xy^2 - y^3

Taking the partial derivative with respect to y:

∂f/∂y = 8xy - 2x^2y - 3xy^2

Setting both partial derivatives equal to zero and solving the resulting system of equations will give us the critical points.

4y^2 - 2xy^2 - y^3 = 0   ...(1)

8xy - 2x^2y - 3xy^2 = 0   ...(2)

From equation (1), we can factor out y^2:

y^2(4 - 2x - y) = 0

This gives us two possibilities: y = 0 or 4 - 2x - y = 0, which simplifies to y = 4 - 2x.

Substituting y = 0 into equation (2), we get:

8xy = 0

This implies that either x = 0 or y = 0.

So, we have three possible cases for the critical points:

Case 1: y = 0, which implies x = 0 from equation (2).

Case 2: x = 0, which implies y = 4 from the equation y = 4 - 2x.

Case 3: Solving the equations 4 - 2x - y = 0 and 8xy - 2x^2y - 3xy^2 = 0 simultaneously will give us additional critical points.

(b) To find the absolute maximum and minimum values of f(x, y) on the closed triangular region D, we need to evaluate the function at the vertices of the triangle and at the critical points found in part (a).

The vertices of the triangle D are (0, 0), (0, 6), and (6, 0).

Evaluate f(x, y) at the vertices:

f(0, 0) = 0

f(0, 6) = 0 - 0 - 0 = 0

f(6, 0) = 4(6)(0)^2 - (6)^2(0)^2 - (6)(0)^3 = 0

Evaluate f(x, y) at the critical points:

f(0, 0) = 0

f(0, 4) = 4(0)(4)^2 - (0)^2(4)^2 - (0)(4)^3 = -64

f(2, 2) = 4(2)(2)^2 - (2)^2(2)^2 - (2)(2)^3 = 8 - 8 - 16 = -16

Therefore, the absolute maximum value of f(x, y) on D is 0, and the absolute minimum value is -64.

The simplified ratio f:h:w is 20:15:8.

The ratio of f:h:w, we need to combine the given ratios of f:h and f:w.

The ratio f:h is given as 4:3 means that for every 4 units of f, there are 3 units of h.

The ratio f:w is given as 5:2 means that for every 5 units of f, there are 2 units of w.

To simplify the ratio f:h:w, we need to find the common factors among the three quantities (f, h, and w).

The common factor is f.

So, the simplified ratio is obtained by dividing each quantity by the common factor f.

Dividing f by f results in 1, which simplifies the ratio.

Dividing h by f gives us h/f, and dividing w by f gives us w/f.

Therefore, the simplified ratio f:h:w is 1:h/f:w/f.

Since h/f = 3/4 and w/f = 2/5, the simplified ratio becomes:

1 : 3/4 : 2/5

To remove the fractions, we can multiply each term by a common multiple of the denominators.

The least common multiple (LCM) of 4 and 5 is 20.

Multiplying the ratio by 20, we get:

20 : (3/4) × 20 : (2/5) × 20

which simplifies to:

20 : 15 : 8
