Answer: this is true

Step-by-step explanation:

The distance traveled by the race car along the circular track is given as follows:

4.33 feet.

Before obtaining the distance traveled by the car, we need to obtain the circumference of the circle.

The circumference of a circle of radius r is given by the multiplication of 2π and r, as follows:

C = 2πr.

The radius for the circle in this problem is of:

r = 2.7 feet.

Then the circumference of the circle is of:

C = 2π x 2.7 = 17 feet.

(replacing r by it's numeric value).

The entire circumference is equivalent to 2π radians. The car traveled 1.6 radians, hence the distance traveled is given as follows:

Distance = 1.6/2π x 17 = 4.33 feet.

The distance between the building and the ladder is 34.876 foot.

A triangle in which one of the angle measure is equal to 90 degree is called a right triangle.

The ladder forms a right triangle with the building and the ground,

The length of the triangle is 40 foot

The angle made by the ladder is 29.32 degree

By using Trigonometric Ratios

cos 29.32 = Base /  Hypotenuse

cos 29.32 = Base / 40

0.8718 × 40 = Base

Base = 34.876 foot

Base is the distance between the building and the ladder.

Base of the ladder = 34.876 foot

→ 9(x-6)+41 = 75. Transposing the like terms.

→ 9(x-6) = 75 - 41 Performing subtraction of the term in RHS

Step-by-step explanation:

we can solve the equation using the inverse of A:\(\[x = A^{-1}v = \begin{bmatrix} -1 & 2 & -5 \\ 5 & -9 & 20 \\ -1 & 2 & -4 \end{bmatrix} \begin{bmatrix} 1 \\ 1 \\ 1 \end{bmatrix} = \begin{bmatrix} -4 \\ 16 \\ -3 \end{bmatrix}\]Therefore, the four vectors:\[u_1 = \begin{bmatrix} 1 \\ -1 \\ 2 \end{bmatrix} , \; u_2 = \begin{bmatrix} 2 \\ 1 \\ 0 \end{bmatrix} , \; u_3 = \begin{bmatrix} -1 \\ 3 \\ -1 \end{bmatrix} , \; v = \begin{bmatrix} -4 \\ 16 \\ -3 \end{bmatrix}\]\)form a basis of .

To do that, we will solve the equation:\[Ax = v\]where x is a column vector of three unknowns. We want v to be linearly independent from the columns of A, so we need the equation to have a unique solution. We can achieve that by taking v to be any vector that is not in the column space of A. For example, we can take:\\([v = \begin{bmatrix} 1 \\ 1 \\ 1 \end{bmatrix}\]\)Then, we can solve the equation using the inverse of A:\(\[x = A^{-1}v = \begin{bmatrix} -1 & 2 & -5 \\ 5 & -9 & 20 \\ -1 & 2 & -4 \end{bmatrix} \begin{bmatrix} 1 \\ 1 \\ 1 \end{bmatrix} = \begin{bmatrix} -4 \\ 16 \\ -3 \end{bmatrix}\]Therefore, the four vectors:\[u_1 = \begin{bmatrix} 1 \\ -1 \\ 2 \end{bmatrix} , \; u_2 = \begin{bmatrix} 2 \\ 1 \\ 0 \end{bmatrix} , \; u_3 = \begin{bmatrix} -1 \\ 3 \\ -1 \end{bmatrix} , \; v = \begin{bmatrix} -4 \\ 16 \\ -3 \end{bmatrix}\]\)form basis of .

The rate of change remains the same over the mentioned intervals, function f cannot be quadratic or exponential.

Hence, it can be concluded that function f is a linear function.

Based on the given information that the rate of change of function f is the same from x = -9 to x = -4 as it is from x = 1 to x = 6, we can conclude that function f is a linear function.

A linear function is characterized by a constant rate of change, meaning that the change in the function's value is consistent over any given interval.

In this case, the rate of change remains the same from x = -9 to x = -4 and from x = 1 to x = 6.

On the other hand, a quadratic function is characterized by a changing rate of change, meaning that the function's value changes at an increasing or decreasing rate over different intervals.

An exponential function, on the other hand, exhibits a rapid growth or decay with an increasing rate of change.

Answer:

40

Step-by-step explanation:

To solve this, we can create an equation that represents this situation. Since Christopher score 7 more than twice what Mathew scored, the equation will be:

C = 2M + 7

(Variables are representative of the first letter of each name)

Seeing as Christopher scored 87, we can put that into the equation and solve for M.

So, the equation will be:

87 = 2M + 7

Subtract 7 from both sides in order to isolate variable M on the right side.

80 = 2M

Now solve for M, which is 40 (divide both sides by 2).

The confidence interval gives us an estimate of where the true population parameter θ likely falls, with a 95% probability. It does not mean that there is a 95% probability that θ is distributed within the interval [a, b].

A 95% confidence interval [a, b] for a parameter (let's call it θ) is a range of values within which the true value of θ is likely to fall with 95% probability. In other words, if we were to repeat the sampling process many times and calculate the confidence intervals, approximately 95% of those intervals would contain the true value of θ.

The correct description for a 95% confidence interval [a, b] is: "With 95% probability, the interval [a, b] covers the true value of θ."

Here's a step-by-step explanation:

1. Collect data: First, gather a random sample from the population of interest.

2. Calculate the sample statistic: Based on the data, calculate the sample statistic (e.g., mean, proportion, etc.) that will be used to estimate the population parameter θ.

3. Determine the standard error: Calculate the standard error of the sample statistic. The standard error measures the variability of the sample statistic across different samples.

4. Find the critical value: Determine the critical value that corresponds to a 95% confidence level. This value depends on the sampling distribution and can be found using a table or a calculator.

5. Calculate the margin of error: Multiply the standard error by the critical value. This gives you the margin of error, which represents the uncertainty in the estimate.

6. Construct the confidence interval: Add and subtract the margin of error from the sample statistic to obtain the lower and upper bounds of the 95% confidence interval, [a, b].

Remember, the confidence interval gives us an estimate of where the true population parameter θ likely falls, with a 95% probability. It does not mean that there is a 95% probability that θ is distributed within the interval [a, b].

Using the tangent ratio to create an equation, the value of x is calculated as: A. 53.6 feet.

We can apply the tangent ratio to write an equation that will enable us solve for the value of x. The tangent ratio is expressed as: tan ∅ = opp. / adj., where:

Given the following:

Reference angle (∅) = 40 degrees.

Opposite side length = 45 ft

Adjacent side length = x ft

Apply the tangent ratio to create an equation:

tan 40 = 45/x

x * tan 40 = 45

Divide both sides by tan 40

x = 45 / tan 40

x ≈ 53.6
