The exponential equation equivalent to the logarithmic equation log; 9=x²+3 is \(10^(^2^+^3^)=9\). Hence the correct option is B.

To determine which exponential equation is equivalent to the given logarithmic equation, let's start by understanding the relationship between logarithms and exponentials.

In general, logarithmic and exponential functions are inverse operations of each other.

This means that if we have a logarithmic equation of the form log(base)b(x) = y, we can rewrite it as an exponential equation: \(b^y = x\).

In the given logarithmic equation log 9 = x² + 3, the base is not specified, so we assume it to be 10 (common logarithm).

To obtain the equivalent exponential equation, we need to rewrite the equation using the exponential form.

Using the inverse relationship, we have:

\(\[10^{(x^2 + 3)} = 9\]\).

Now let's analyze the provided options to determine which one matches this equation:

A. 10⁰ = 2² + 3: This equation does not match the original equation.

B. \(10^(^2^+^3^)=9\): This equation matches the original equation, as both sides are equal to 9.

C. (2² + 3) = 10: This equation does not match the original equation.

D. (x² + 3) * 10 = 9: This equation does not match the original equation.

Based on the analysis, option B. \(10^(^2^+^3^)=9\) is the exponential equation equivalent to the given logarithmic equation log 9 = x² + 3.

A 24 factorial design has been run in a pilot plant to investigate the effect of four factors on the molecular weight of a polymer.

(a) To construct a normal probability plot of the effects, follow these steps:
1. Calculate the main effects (A, B, C, D) and interaction effects (AB, AC, AD, BC, BD, CD, ABC, ABD, ACD, BCD, ABCD) using the given data.
2. Rank the effects in ascending order based on their absolute values.
3. Calculate the percentile for each effect using the formula: (i - 0.5) / n, where i is the rank and n is the total number of effects (in this case, 15).
4. Find the corresponding z-scores for each percentile from a standard normal distribution table.
5. Plot the z-scores against the effects in a scatter plot.

Active effects are those that deviate significantly from the straight line formed by the majority of the points in the plot.

(b) To construct an appropriate model and test for significant effects:
1. Include only the active effects identified in step (a) in your model.
2. Fit the model using multiple linear regression or another suitable method.
3. Perform hypothesis testing on the coefficients of the effects included in the model using t-tests or F-tests. If the p-value is below a chosen significance level (e.g., 0.05), then the effect is considered significant.

(c) To analyze the residuals from the model:
1. Calculate the residuals (observed - predicted values) for each observation.
2. Create a normal probability plot of the residuals using the same method described in step (a).
3. If the residuals follow a straight line, it indicates that they are normally distributed, which is an important assumption in linear regression models.
4. Plot the residuals against the predicted values of Y in a scatter plot to check for any patterns or trends. If no patterns are observed, it suggests that the model is a good fit for the data.

By following these steps, you'll be able to identify the active effects, construct an appropriate model, and analyze the residuals.

The dimensions of the poster be so that the least amount of poster is used are 10 and 20 inches.

Print area of the rectangular poster =128 in²

Let  "x"  and  "y" be the  dimensions for the print area of the poster .

And A[p] = print area of poster

⇒A(p)  = Print area of the poster = xy

⇒128 = xy    

⇒ y  = 128/x

Total area of the poster is:

A( t ) = ( y + 4 )( x + 2 )

A( t ) = yx +2y +4x + 8    And as  y = 128/x

Poster 's area as function of x is -

A(x)  =( 128 /x)x + 2 (128/x) + 4x + 8

⇒ A(x)  = 128 x² + 256/x + 4x + 8    ⇒  A(x)  = 128 + 256 /x + 4*x

On taking the derivatives on both sides of the equation :

A´(x)  =  - 256/x² + 4

A´(x)  = 0        

⇒ - 256 /x²  = -4    

⇒  4x² = 256

⇒ x² = 256/4     ⇒  x²  = 64

x = 8inches

And   y  =  128/x    

⇒y = 128/8   ⇒ y = 16 inches

After finding out the values of x and y the dimensions of the poster are:

w = x + 2    ⇒  w  = 8+ 2    w  = 10 in

Y  = y + 4   ⇒  Y  = 16+ 4   Y  =  20 in

Hence, the dimensions of the poster be so that the least amount of poster is used are 10 and 20 inches.

Answer:

The surface area of this cuboid is 420 square inches.

Step-by-step explanation:

All we have to do is calculate each rectangle. For the width, we have 10 x 5 which is 50. Then we multiply it by 2 because we have two of those sides. Then we get 100. Then we have 11 x 5 which is 55. We multiply that by 2 and we get 110. Then we do that to the final two sides and we get 220. So the final answer if we add them all up is 420 square inches.

Therefore, at the given point (1, 1, 2, 4), ∂u/∂t = (ln(2) / 2) × ∂t/∂u, and ∂t/∂u cannot be determined from the given equation.

To calculate the partial derivatives ∂u/∂t and ∂t/∂u using implicit differentiation of the given equation, we'll differentiate both sides of the equation with respect to the variables involved, treating the other variables as constants.

Let's break it down step by step:

Given equation: (-2ln(-x) = ln(2)(tx - v) × 2ln(w - uv) = ln(2)

We'll differentiate both sides of the equation with respect to u and t, treating x, v, and w as constants.

Differentiating with respect to u:

Differentiate the left-hand side:

d/dt (-2ln(-x)) = d/dt (ln(2)(tx - v))

-2(1/(-x)) × (-1) × dx/du = ln(2)(t × du/dt - 0) [using chain rule]

Simplifying the left-hand side:

2(1/x) × dx/du = ln(2)t × du/dt

Differentiating with respect to t:

2ln(w - uv) × d/dt (w - uv) = 0 × d/dt (ln(2))

2ln(w - uv) × (dw/dt - u × dv/dt) = 0

Since the second term on the right-hand side is zero, we can simplify the equation further:

2ln(w - uv) × dw/dt = 0

Now, we substitute the given values (1, 1, 2, 4) into the equations to find the partial derivatives at that point.

At (1, 1, 2, 4):

-2(1/(-1)) × dx/du = ln(2)(1 × du/dt - 0)

2 × dx/du = ln(2) × du/dt

dx/du = (ln(2) / 2) × du/dt

2ln(w - uv) × dw/dt = 0

Since the derivative is zero, it doesn't provide any information about ∂t/∂u.

Therefore, at the given point (1, 1, 2, 4):

∂u/∂t = (ln(2) / 2) × ∂t/∂u

∂t/∂u cannot be determined from the given equation.

The slope of the line that passes through the points (-5, 6) and (-9, -6) is 3

What is slope ?

A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).

Let the given points as shown:

(x1,y1)= (-5, 6) and (x2,y2)= (-9, -6)

Slope = m = (y2-y1) /( x2-x1)

                 = (-6-6) /(-9-(-5))

                 = -12/-4

                 = 3

Step-by-step explanation:

To answer question a, we use the formula:

time taken = (number of tyres to fit x time taken to fit one tyre) / number of tyres fitted at once

In this case, Liam takes 124 minutes to fit 4 tyres to a lorry. To find out how long it would take him to fit 6 tyres, we plug in the values:

time taken = (6 x 124) / 4
time taken = 186 minutes

So it would take Liam 186 minutes to fit 6 tyres to a lorry.

For question b, we know that Liam takes 124 minutes to fit 4 tyres, so he takes 31 minutes to fit 1 tyre. If he works for 93 minutes, we can find out how many tyres he can fit:

number of tyres = time taken / time taken to fit one tyre
number of tyres = 93 / 31
number of tyres = 3

So Liam can fit 3 tyres in 93 minutes.

The answer is option d. -1.865, as it is the value that satisfies P(Z ≤ b) = 0.0311. The other options (-1.87, -1.86, -1.8) do not correspond to the given cumulative probability.

In this scenario, P(Z ≤ b) represents the cumulative probability of a standard normal distribution up to the value of b. To find the corresponding value of b, we need to find the z-score that corresponds to a cumulative probability of 0.0311.

By looking up the z-table or using a statistical calculator, we can find that the z-score corresponding to a cumulative probability of 0.0311 is approximately -1.865.

Therefore, the answer is option d. -1.865, as it is the value that satisfies P(Z ≤ b) = 0.0311. The other options (-1.87, -1.86, -1.8) do not correspond to the given cumulative probability.
