hooe this helps

Answer:

The slope is -5/6 and the y intercept is -2.

Step-by-step explanation:

One way to solve is rewriting the standard form ax+by=c to slope intercept form y=mx+b

5x+6y=-12

6y=-12-5x

Divide both sides by 6.

6y/6 = (-12-5x)/6

y=-2-(5/6)x

The slope is -5/6 and the y intercept is -2.

The value of a is of a = -1/3 and the equation of f(x) in factored form is f(x) = -1/3(x + 5)(x - 9)

We are given the roots for each function, hence the factor theorem is used to define the functions.

The function is defined as a product of it's linear factors, if x = a is a root, then x - a is a linear factor of the function.

The roots for this problem are given as follows:

Hence the function in factored form is defined as follows:

f(x) = a(x + 5)(x - 9)

When x = -2, f(x) = 11, hence the leading coefficient a is given as follows:

11 = a(3)(-11)

-33a = 11

33a = -11

a = -1/3.

Hence the equation is:

f(x) = -1/3(x + 5)(x - 9).

Answer:

To compute the average speed, multiply the total distance travelled by the whole time spent. There's a formula for speed, time and distance

Travel distance aboard the pterodactyl = 10 mph x 3 hours = 30 miles

Distance travelled on the spinosaurus = 2 miles x 1 hour = 2 miles

30 miles + 2 miles = 32 miles total distance travelled

Total time required = 3 hours + 1 hour = 4 hours

Average speed = total distance travelled divided by the total time taken = 32 miles divided by 4 hours = 8 mph

As a result, our average speed is 8 mph.

Answer:

It would take 6 workers 16 days to complete the job.

This is because the number of workers and the number of days are inversely proportional. This means that if the number of workers increases, the number of days will decrease, and vice versa.

In this case, the number of workers has decreased from 8 to 6. This means that the number of days will increase from 12 to 16.

Here is the formula for calculating the number of days it would take 6 workers to complete the job:

Number of days = (Number of workers x Number of days) / (New number of workers)

Plugging in the values, we get the following:

Number of days = (8 x 12) / 6 = 16

Therefore, it would take 6 workers 16 days to complete the job.

The expression tan²θ-Sin²θ = tan²θsin²θ is proven that the left hand side is equal to the right hand side.

To prove the expression, tan²θ-Sin²θ = tan²θsin²θ, start from the left-hand side and use the trigonometric identity tan²θ = sin²θ/cos²θ and the Pythagorean identity sin²θ + cos²θ = 1.

Starting from the left-hand side:

tan²θ - sin²θ = (sin²θ/cos²θ) - sin²θ

= sin²θ (1/cos²θ - 1)

= sin²θ ((1-cos²θ)/cos²θ)

= sin²θ (sin²θ/cos²θ)

= tan²θ sin²θ

Thus, it is shown that the left-hand side is equal to the right-hand side: tan²θ - sin²θ = tan²θ sin²θ.

The z-score of 1.6 corresponds to a probability of 0.0548 or 5.48%. Therefore, the probability that the force acting on the column is greater than 17 kips is 5.48%.

To answer this question, we need to use the concept of deviation. The deviation measures the distance of a data point from the mean. In this case, the mean force acting on the column is 15.0 kips, and the standard deviation is 1.25 kips.
We can use the normal distribution formula to calculate the probability that the force will be within a certain range. Since we are interested in the probability that the force is greater than a certain value, we need to calculate the z-score corresponding to that value. The z-score is the number of standard deviations that the value is from the mean.
To calculate the z-score, we use the formula:
z = (x - mu) / sigma
where x is the value we are interested in, mu is the mean, and sigma is the standard deviation. In this case, we want to find the probability that the force is greater than a certain value, say 17 kips.
z = (17 - 15) / 1.25

= 1.6
In summary, the deviation of a data point from the mean is an important concept when calculating probabilities using the normal distribution. By calculating the z-score, we can determine the probability that a data point falls within a certain range. In this case, the probability that the force acting on the column is greater than 17 kips is 5.48%.

The correct answer is B. The derivative is 2x - 49.

To find the derivative of the function (x - 50 + (x + 1)), we can apply the product rule, which states that the derivative of the product of two functions is the first function times the derivative of the second function, plus the second function times the derivative of the first function.

Let's break down the given function into its components:

f(x) = (x - 50) + (x + 1)

To differentiate this function, we can consider each term separately:

Term 1: (x - 50)

Term 2: (x + 1)

Now, applying the product rule, we differentiate each term and combine the results:

Derivative of Term 1 = 1  (since the derivative of x is 1)

Derivative of Term 2 = 1  (since the derivative of x is 1)

Using the product rule, the derivative of the function is:

f'(x) = (x - 50) * 1 + (x + 1) * 1

f'(x) = x - 50 + x + 1

f'(x) = 2x - 49

It represents exponential growth. As x increases, the value of f(x) will increase at an accelerating rate, reflecting the steady growth rate of 8.5% each year in the US credit card debt.

The given equation, f(x) = 86(1.085)^x, represents the US credit card debt in billions of dollars over time. To determine whether this equation shows exponential growth or exponential decay, we need to analyze the properties of the function.

Exponential growth is characterized by an increasing value over time. In this case, if the value of f(x) is increasing as x increases, then it indicates exponential growth.

Let's examine the equation: f(x) = 86(1.085)^x.

The base of the exponential term, 1.085, is greater than 1. This implies that the value of f(x) will grow exponentially as x increases. Each time x increases by 1, the term (1.085)^x will be multiplied by 1.085, causing the function to grow even further. This multiplication by a constant greater than 1 ensures exponential growth.

Additionally, the initial value, 86 billion, further supports the idea of growth. As x increases, the exponential term will cause the function to increase rapidly, reflecting the compounding effect of the growth rate.

The sum of the first ten terms of the sequence is approximately -22.17.

Let the first term of the sequence be a, and let the common ratio be r. Then the third term is ar², the fourth term is ar³, and the fifth term is ar⁴.

We are given:

ar² + ar³ = -12

ar² + ar⁴ = 60

ar³ + ar⁴ = 24

Subtracting the first equation from the second gives:

ar⁴ - ar³ = 72

Subtracting the first equation from the third gives:

ar⁴ -ar²= 36

Dividing these two equations gives:

r - 1/r = 2

Multiplying both sides by r gives:

r² - 1 = 2r

r² - 2r - 1 = 0

Using the quadratic formula, we find:

r = 1 + √2 or r= 1- √2

Since the terms of the sequence must be real numbers, we can discard the second solution. Therefore, the common ratio is:

r = 1 + √(2)

To find the first term a, we can use the equation:

ar² + ar³ = -12

Substituting r and simplifying, we get:

a = -12 / (3 + 2√(2))

The store keeper used 125 pounds of flour worth $2.40 per pound and 175 pounds of flour worth $3 per pound to get 300 pounds of mixed flour.

The assertion that two expressions are equal when they are connected by the equals sign ("="), is the mathematical definition of an equation. As an example, 2x - 5 = 13. The equations in this example are 2x - 5 and 13. The symbol "=" links these two expressions together.

Let x be the number of pounds of the flour worth $2.40 per pound, and y be the number of pounds of the flour worth $3 per pound. Since the store keeper wants to end up with 300 pounds of flour, we have:

x + y = 300

We also know that the store keeper wants to sell the mixed flour for $2.05 per pound. This means that the total cost of the flour (x pounds at $2.40 per pound, plus y pounds at $3 per pound) must be equal to:

300 pounds × $2.05 per pound = $615

In other words:

2.40x + 3y = 615

Two equations with two unknowns are now present:

x + y = 300

2.40x + 3y = 615

We can find x and y using algebra. One way to do this is to solve the first equation for x:

x = 300 - y

We can then substitute this expression for x into the second equation:

2.40(300 - y) + 3y = 615

Expanding the parentheses and simplifying, we get:

720 - 2.4y + 3y = 615

0.6y = 105

y = 175

So, the store keeper used 175 pounds of flour worth $3 per pound. To find the amount of flour worth $2.40 per pound, we can substitute y = 175 into the equation x + y = 300:

x + 175 = 300

x = 125

Therefore, the store keeper used 125 pounds of flour worth $2.40 per pound and 175 pounds of flour worth $3 per pound to get 300 pounds of mixed flour.

There is no significance difference in the variation in the listening times for men and women.

In this study conducted by Arbitron Media Research Incorporated, the iPod listening habits of men and women were examined. One aspect of the study focused on the mean listening time for both genders. The objective is to determine if there is a significant difference in the variation of listening times between men and women. To do so, statistical analysis will be conducted using the given data.

To determine if there is a significant difference in the variation of listening times between men and women, we can perform a hypothesis test. Let's denote the mean listening time for men as μ₁, the mean listening time for women as μ₂, the standard deviation for men as σ1, and the standard deviation for women as σ₂.

Null Hypothesis (H₀): There is no difference in the variation of listening times between men and women. In mathematical terms, H₀ : σ₁ = σ₂.

Alternative Hypothesis (H₁): There is a difference in the variation of listening times between men and women. In mathematical terms, H₁ : σ₁ ≠ σ₂.

We will use a significance level of 0.10, which indicates that we are willing to accept a 10% chance of rejecting the null hypothesis when it is true.

To test this hypothesis, we can use the F-test for comparing variances. The F-test compares the ratio of the variances between two independent samples. In this case, the samples are the listening times of men and women. The F-test statistic is calculated as follows:

F = (s₁²) / (s₂²)

where s₁ and s₂ are the sample variances. In this case, the sample variances are the square of the standard deviations provided.

Let's calculate the F-test statistic using the given data:

For men:

Sample size (n₁) = 8

Sample standard deviation (s₁) = 12 minutes/day

Sample variance (s₁²) = (12²) = 144 minutes²/day²

For women:

Sample size (n₂) = 10

Sample standard deviation (s₂) = 16 minutes/day

Sample variance (s₂²) = (16²) = 256 minutes²/day²

Calculating the F-test statistic:

F = (s₁²) / (s₂²) = 144 / 256 ≈ 0.5625

Next, we need to determine the critical value for the F-test statistic at a significance level of 0.10. This critical value can be found in the F-distribution table. Since the sample size is small, we will use the F-distribution table.

With a sample size of 8 for men and 10 for women, the degrees of freedom for the numerator (df₁) is 7 (n₁ - 1) and the degrees of freedom for the denominator (df₂) is 9 (n₂ - 1).

Looking up the critical value from the F-distribution table with df₁ = 7 and df₂ = 9, at a significance level of 0.10, we find the critical value to be approximately 2.76.

Now, we compare the calculated F-test statistic with the critical value. If the calculated F-test statistic is greater than the critical value, we reject the null hypothesis; otherwise, we fail to reject the null hypothesis.

In this case, the calculated F-test statistic (0.5625) is less than the critical value (2.76). Therefore, we fail to reject the null hypothesis. This means that there is no enough evidence to conclude that there is a significant difference in the variation of listening times between men and women at the 0.10 significance level.
