Answer:

9 3/8.

Step-by-step explanation:

multiply 3 3/4 times 2 1/2.

When the expression inside the logarithm becomes zero, the natural logarithm is undefined and approaches negative infinity. In (c), as x approaches 9 from the left, the denominator becomes zero, resulting in the natural logarithm approaching infinity. In (d), as x approaches infinity, the expression 8/x approaches zero, and the natural logarithm of zero is negative infinity.

(a)  To evaluate the limit lim ln(x^2 - 25) as x approaches 5+, we substitute x = 5 into the function:

lim ln(x^2 - 25) = ln((5^2) - 25) = ln(0) = -INFINITY

(b)  To evaluate the limit lim ln(x^2 - 49) as x approaches -7-, we substitute x = -7 into the function:

lim ln(x^2 - 49) = ln((-7^2) - 49) = ln(0) = -INFINITY

(c) To evaluate the limit lim ln(1/(9 - x)) as x approaches 9-, we substitute x = 9 into the function:

lim ln(1/(9 - x)) = ln(1/(9 - 9)) = ln(1/0) = INFINITY

(d)  To evaluate the limit lim ln(8/x) as x approaches infinity, we substitute x = infinity into the function:

lim ln(8/x) = ln(8/infinity) = ln(0) = -INFINITY

Note: In (a) and (b), when the expression inside the logarithm becomes zero, the natural logarithm is undefined and approaches negative infinity. In (c), as x approaches 9 from the left, the denominator becomes zero, resulting in the natural logarithm approaching infinity. In (d), as x approaches infinity, the expression 8/x approaches zero, and the natural logarithm of zero is negative infinity.

Answer:

The sum of the two acute angles in a right triangle is always 90°, we can conclude that the smaller acute angle is 50°.

Step-by-step explanation:

To find the smaller acute angle in the right triangle, we can solve the given equation using inverse trigonometric functions.

sin(9°) = cos(41°)

Using the fact that sin(x) = cos(90° - x), we can rewrite the equation as:

sin(9°) = sin(90° - 41°)

Now, we can set the angles inside the sin function equal to each other:

9° = 90° - 41°

Rearranging the equation, we get:

41° = 90° - 9°

Combining like terms, we have:

41° + 9° = 90°

Simplifying further:

50° = 90°

Since the sum of the two acute angles in a right triangle is always 90°, we can conclude that the smaller acute angle is 50°.

The error in writing the rule for the nth term of the geometric sequence is in the step where the value of a₁ is determined. The correct value for a₁ is √(147/49) or √3, not √√21.

In a geometric sequence, each term is obtained by multiplying the previous term by a constant ratio (r). The general formula for the nth term (aₙ) of a geometric sequence is given by aₙ = a₁ * r^(n-1), where a₁ is the first term and r is the common ratio.
Given that a₃ = 147 and r = 7, we can find the value of a₁ by substituting these values into the formula. Let's correct the error in the calculation step:
a₃ = a₁ * r^(3-1)
147 = a₁ * 7²
147 = a₁ * 49
To isolate a₁, we divide both sides of the equation by 49:
a₁ = 147 / 49
a₁ = 3
Therefore, the correct value for a₁ in the geometric sequence is 3, not √√21 as stated in the error.

From the above-mentioned data, it can be inferred that: When the price of good 1 decreases, the substitution effect causes the individual to change consumption of good 1 by 10 while the income effect causes the individual to change consumption of good 1 by −6.

The total effect can be calculated as the sum of both substitution and income effects. The total effect = substitution effect + income effect= 10 - 6= 4Thus, the total effect is 4.Now, to determine whether good 1 is normal or inferior, we need to consider the sign of the income effect.

If the income effect is negative, the good is inferior, and if it's positive, the good is normal.Since the income effect here is negative (-6), we can conclude that good 1 is inferior.

According to the given data, we can calculate the total effect, which is the sum of the substitution and income effects.  The substitution effect refers to the change in consumption of a good due to the relative price change, while the income effect refers to the change in consumption of a good due to the purchasing power change.  when the price of good 1 decreases, the substitution effect causes the individual to change consumption of good 1 by 10, while the income effect causes the individual to change consumption of good 1 by −6. Therefore, the total effect can be calculated as the sum of both substitution and income effects, which is 10 - 6 = 4.From the data, it can also be determined whether good 1 is normal or inferior. A good is considered normal when its income effect is positive and inferior when its income effect is negative. Since the income effect here is negative (-6), it can be concluded that good 1 is inferior.Thus, the total effect is 4, and good 1 is inferior.

The total effect is 4, and good 1 is inferior.

The number in a radical needs to be square rooted to get placed out of it, so the square root of 20 can be split into the square root of 4 times the square root of 5, which can then be simplified to 2 rad 5, but there is a 2 outside of the radical, so then it becomes 4 rad 5, which is equivalent to 4 rad 5 so the first one is an answer.

Raising a number to the exponent of 1/2 is basically square rooting it.

For the second one, it's rad 6 - rad 5, which is not equal to 4 rad 5. That is not an answer.

For the third one, it's 3 times rad 5 + rad 5. That's 3rad5 + rad5. That's 4 rad 5, which is equal to 4 rad 5 at the top, so this is an answer.

For the fourth one, it's 4 times rad 5, so that's 4 rad 5, which is equal to 4 rad 5. That is an answer.

For the fifth one, 10 cannot be simplified to get out of the radical because it's only factors are 2 and 5, and neither of them are squares. That is not an answer.

For the sixth one, it's 3 times rad 5, so it's 3 rad 5. That is not an answer.

The answers are the first one, third one, and fourth one.

The general solution to the linear system Ax = b is X = Xp + Xn, where Xp = [3, -1, 0]T and Xn = [t, s, t]T.

Given the coefficient matrix A and the constant vector b, we can set up the augmented matrix [A|b] and perform row operations to find the row-echelon form. The row-echelon form will help us determine the particular solution Xp and the solution Xn.

Performing row operations on the augmented matrix [A|b], we have:

[1 2 -1 | 3]

[2 -2 2 | -3]

[3 3 3 | 0]

After performing row operations, we obtain the row-echelon form:

[1 2 -1 | 3]

[0 -6 4 | -9]

[0 0 0 | 0]

From the row-echelon form, we can determine that the system has a free variable, which means it has infinitely many solutions. The associated homogeneous system of equations has a solution of the form Xn = [t, s, t]T, where t and s are free variables.

To find the particular solution Xp, we set the free variables to 0 and solve for the remaining variables in the row-echelon form. In this case, we obtain Xp = [3, -1, 0]T.

Therefore, the general solution to the linear system Ax = b is X = Xp + Xn, where Xp = [3, -1, 0]T and Xn = [t, s, t]T.

The given information consists of a series of equations involving variables b1, b3, and b4, as well as the constant values 8, 9, and 10. The objective is to calculate the value of b3.

To find the value of b3, we need to analyze the given equations and use algebraic techniques to solve for the unknown variable.
From the equations given, we can observe that b1 = 10, b4 = 9, and 62 = 8. These values provide fixed points of reference.
Next, we examine the equations involving b3. We have two equations: b3 - a = 15 and b3 - b = 10. However, there is no information provided about the values of a and b. Without additional information or constraints, we cannot determine the specific value of b3.
It is important to note that the solution to the problem depends on having all the necessary information or additional equations that can be used to solve for the unknowns. In this case, the lack of information about the values of a and b prevents us from calculating the exact value of b3.

The lifespans of lions in a particular zoo are normally distributed. The average lion lives 12.5 years; the standard deviation is 2.4 years. Use the empirical rule (68-95-99.7\%)(68−95−99.7%) to estimate the probability of a lion living between 5.3 to 10. 1 years.

Answer:

Thehe probability of a lion living between 5.3 to 10. 1 years is 0.1585

Step-by-step explanation:

The empirical rule formula states that:

1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

3) 99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

Mean is given in the question as: 12.5

Standard deviation : 2.4 years

We start by applying the first rule

1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

μ - σ

12.5 -2.4

= 10.1

We apply the second rule

2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

μ – 2σ

12.5 - 2 × 2.4

12.5 - 4.8

= 7.7

We apply the third rule

3)99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

μ - 3σ

= 12.5 - 3(2.4)

= 12.5 - 7.2

= 5.3

From the above calculation , we can see that

5.3 years corresponds to one side of 99.7%

Hence,

100 - 99.7%/2 = 0.3%/2

= 0.15%

And 10.1 years corresponds to one side of 68%

Hence

100 - 68%/2 = 32%/2 = 16%

So,the percentage of a lion living between 5.3 to 10. 1 years is calculated as 16% - 0.15%

= 15.85%

Therefore, the probability of a lion living between 5.3 to 10. 1 years

is converted to decimal =

= 15.85/ 100

= 0.1585

Answer:

The probability of a particular lion living less than 10.1 years is 16%

Answer:

284/3 πx³

Step-by-step explanation:

Volume of a cylinder is expressed as shown:

V = πr²h

r is the radius of the cylinder

r = diameter/2

r = 8x/2

r = 4x

Height of the cylinder = 6x

Volume of the roll with out the hole

V = π(4x)²(6x)

V = 16x²π(6x)

V = 96πx³

The hole in the middle will be a solid sphere with diameter 2x (radius will be x)

Volume of the hole = 4/3πr³

Volume if the hole = 4/3πx³

Volume of the toilet paper roll = volume of the roll without a hole - volume of the hole

= 96πx³ - 4/3πx³

= (96-4/3)πx³
