The statement about the unit prices which is true is Kitty Kibbles has a lower unit price of $1.30/pound.

The correct answer choice is option D.

Cost of 16-pound bag of Kitty Kibbles = $20.80

Unit price of kitty kibbles = Price / number of pounds

= $20.80 / 16

= $1.30 per pound.

Step-by-step explanation:

What are the factors of: f(x) = \(x ^2 + 2x - 8\)

\(x ^2 + 2x - 8\)

a = 1

b =  2

c = -8

Find two numbers that add to 2 and multiply to -8:

-2 + 4 = 2

-2(4) = -8

factors are:

(x - 2)(x + 4)

Answer:

a. The present value of these receivables is $42,123.64

b. The total value at the end of 10 years is $69,257.02

c. The present value of these payments is $10,059.37

Step-by-step explanation:

1.\((x - 1)^2 / (2x^2)\)

2. Requires specific values for x to simplify further.

3. \(cot^2x\) is equivalent to \((cos^2x / sin^2x).\)

4. \((x^2 - 2x^3 + 7) / x\)

5. The equation represents a quadratic function with an inverted "U" shape.

S1: To simplify the expression, let's start by factoring out common terms from the numerator. We can factor out an \(x^4\), which leaves us with \(x^2 - 2x + 1\) . The denominator remains as \(2x^2\). Simplifying further, we have \((x^2 - 2x + 1) / (2x^2)\) . This expression can be rewritten as \((x - 1)^2 / (2x^2).\)

S2: To simplify the expression, let's break it down into individual terms. The first term is sec^3x, the second term is \(e^xsecx,\) and the third term is 1/secx. Unfortunately, we cannot simplify this expression further without specific values for x.

S3: The expression \(cot^2x\) represents the square of the cotangent of x. This can be rewritten as (cos^2x / sin^2x). Using the trigonometric identity cot^2x = 1 / tan^2x, we have 1 / tan^2x = (cos^2x / sin^2x). Therefore, cot^2x is equivalent to (cos^2x / sin^2x).

S4: The expression \((x^2 - 2x^3 + 7)\) / (cuberoot(x)) can be simplified by applying the rules of exponents. We can rewrite cuberoot(x) as x^(1/3), and then divide the exponents. This gives us\(x^(2 - 3(1/3)) = x^(2 - 1) = x^1\)= x. Therefore, the simplified expression becomes x^2 - 2x^3 + 7 / x.

S5: The equation \(y = x^(1/2) - x^2 + 2x\) represents a quadratic function. To analyze its behavior, we look at the exponents of x. The term x^(1/2) represents the square root of x, which has a non-negative value. The term -x^2 represents a downward-facing parabola, and the term 2x represents a linear function.

Thus, the overall graph would be a combination of these shapes. It starts from the top left quadrant, curves downward due to the negative x^2 term, and intersects the x-axis at one or two points depending on the discriminant of the quadratic equation. The linear term then pulls the curve upward, resulting in a graph that generally looks like an inverted "U" shape.

Step-by-step explanation:

I think It's just asking to put some ratios that go with the one given.

The bakery should use the range to determine whether or not the equipment changes have worked. The correct answer is C.

To determine whether the equipment changes made by the bakery have resulted in more uniform-sized muffins, they should use the measure of variability. The most suitable measure, in this case, would be the range.

The range is calculated by finding the difference between the maximum and minimum values in a data set. In this scenario, the bakery made 25 muffins and measured each one. By finding the range of the measurements, they can assess the spread of sizes among the muffins.

Here's how they can use the range to evaluate the effectiveness of the equipment changes:

Collect the measurements of all 25 muffins.

Determine the maximum and minimum measurements.

Calculate the range by subtracting the minimum measurement from the maximum measurement.

If the range of the muffin sizes is smaller compared to the range before the equipment changes, it suggests that the modifications have resulted in more uniform-sized muffins. Conversely, if the range remains similar or larger, it indicates that the changes might not have effectively improved the uniformity of muffin sizes.

Therefore, the bakery should use the range to determine whether or not the equipment changes have worked. The correct answer is C.

The number of nickels is 20 and the number of dimes is 10.

Given:

Brooklyn has $2 worth of nickels and dimes. She has a total of 30 nickels and dimes altogether.

Let x and y be the number of nickels and dimes.

0.05x + 0.10y = 2.0

multiply by 100 on both sides

5x + 10y = 200

x + y = 30

y = 30 - x

substitute y value in 5x + 10y = 200

5x + 10(30 - x) = 200

5x + 300 - 10x = 200

-5x = -100

5x = 100

divide by 5 on both sides

x = 100/5

Answer:

Step-by-step explanation:

The probability that a sample of size n = 62 is randomly selected with a mean between 189.7 and 213 is approximately 0.9702.

To find the probability that a single randomly selected value is between 189.7 and 213, we can use the standard normal distribution.

Step 1: Calculate the z-scores for the given values using the formula:

  z = (x - μ) / σ

  For 189.7:

  z1 = (189.7 - 189.7) / 96.7 = 0

  For 213:

  z2 = (213 - 189.7) / 96.7 ≈ 0.2417

Step 2: Utilize a standard typical conveyance table or number cruncher to find the probabilities comparing to the z-scores.

  P(189.7 < X < 213) = P(0 < Z < 0.2417) ≈ 0.0939

Therefore, the probability that a single randomly selected value is between 189.7 and 213 is approximately 0.0939.

To find the probability that a sample of size n = 62 is randomly selected with a mean between 189.7 and 213, we use the central limit theorem. Under specific circumstances, the testing dispersion of the example mean methodologies a typical conveyance

Step 1: Calculate the standard error of the mean (σ_m) using the formula:

  σ_m = σ / sqrt(n)

  σ_m = 96.7 / sqrt(62) ≈ 12.2878

Step 2: Convert the given qualities to z-scores utilizing the equation:

  z = (x - μ) / σ_m

  For 189.7:

  z1 = (189.7 - 189.7) / 12.2878 = 0

  For 213:

  z2 = (213 - 189.7) / 12.2878 ≈ 1.8967

Step 3: Utilize a standard typical conveyance table or mini-computer to find the probabilities relating to the z-scores.

  P(189.7 < M < 213) = P(0 < Z < 1.8967) ≈ 0.9702

Therefore, the probability that a sample of size n = 62 is randomly selected with a mean between 189.7 and 213 is approximately 0.9702.

The shareholder's equity if $450 was put on credit is $175. Option D

The purchase of equipment for $625 represents a decrease in the company's shareholder equity, since assets have increased while the equity has not changed.

If $450 was put on credit, this means that the company has only paid $625 - $450 = $175 towards the equipment.

The shareholder's equity is reduced by this amount, so the new shareholder's equity is:

Shareholder's equity = Initial equity - Decrease in equity

Shareholder's equity = 0 - $175

Shareholder's equity = -$175

Since the shareholder's equity is negative, it means that the company owes more than it owns. Therefore, the answer $175.

Answer:

22° + m<C = 90°

Step-by-step explanation:

We are given that <A (which is equal to 22°) and <B are vertical angles, and that <B is complementary to <C.

We want to write an equation that will help us solve <C.

Recall that vertical angles are congruent by vertical angles theorem.

This means that <A ≅ <B; it also means that the measure of <B is also 22°.

Also recall that complementary angles add up to 90°.

This means that m<B + m<C = 90°.

Since we deduced that m<B is 22°, we can substitute that value into the equation.

Hence, an equation that can be used to solve for <C is:

22° + m<C = 90°

Answer:

f(x) = x³ - 4x + 6

f'(x) = 3x² - 4

a) f'(2) = 3(2²) - 4 = 12 - 4 = 8

6 = 8(2) + b

6 = 16 + b

b = -10

y = 8x - 10

b) 3x² - 4 = 0

3x² = 4, so x = ±2/√3 = ±(2/3)√3

= ±1.1547

f(-(2/3)√3) = 9.0792

f((2/3)√3) = 2.9208

c) 3x² - 4 = 8

3x² = 12

x² = 4, so x = ±2

f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6

6 = -2(8) + b

6 = -16 + b

b = 22

y = 8x + 22

f(2) = 6

y = 8x - 10

The equation perpendicular to the tangent is y = -1/8x + 25/4

-The smallest slope on the curve is 2.92

The curve has the smallest slope at the point (1.15, 2.92)

The equations at tangent points are y = 8x + 16 and  y = 8x - 16

From the question, we have the following parameters that can be used in our computation:

y = x³ - 4x + 6

Differentiate

So, we have

f'(x) = 3x² - 4

The point is (2, 6)

So, we have

f'(2) = 3(2)² - 4

f'(2) = 8

The slope of the perpendicular line is

Slope = -1/8

So, we have

y = -1/8(x - 2) + 6

y = -1/8x + 25/4

We have

f'(x) = 3x² - 4

Set to 0

3x² - 4 = 0

Solve for x

x = √[4/3]

x = 1.15

So, we have

Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6

Smallest slope = 2.92

So, the smallest slope is 2.92 at (1.15, 2.92)

Here, we set f'(x) to 8

3x² - 4 = 8

Solve for x

x = ±2

Calculate y at x = ±2

y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)

y = (2)³ - 4(2) + 6 = 6: (2, 0)

The equations at these points are

y = 8x + 16

y = 8x - 16
