Step-by-step explanation:

y-6 = 4/7 (x-(-4)

y - 6 = 4/7 (x+4)

y - 6 = 4/7 x + 16/7

y = 4/7 x + 16/7 + 6

y = 4/7 x + (16+42)/7

y = 4/7 x + 58/7

10 = 4/7 x + 58/7

4/7 x = 10 - 58/7

4/7 x = (70-58)/7

4/7 x = 12/7

7/4 * 4/7 x = 12/7 * 7/4

Answer:

\(f(x)=\frac{1}{2}x+-6\) or y=1/2x+-6

Step-by-step explanation:

You can use any two points on a line to find slope. For example, I used:

(x1, y1) 2, -5

(x2, y2) 4, -4

To find slope, the following formula is needed:

\(m=\frac{y_2-y_1}{x_2-x_1}\)

Input our values:

\(m=\frac{(-4)-(-5)}{4-2}\) which means m=1/2

b is equal to y-intercept which is -6

The equation is:

\(y=\frac{1}{2}x+-6\)

to get the equation of any straight line, we simply need two points off of it, let's use the points from the picture below.

\((\stackrel{x_1}{-4}~,~\stackrel{y_1}{-8})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-4}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-4}-\stackrel{y1}{(-8)}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{(-4)}}} \implies \cfrac{-4 +8}{4 +4} \implies \cfrac{ 4 }{ 8 }\implies \cfrac{1}{2}\)

\(\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-8)}=\stackrel{m}{\cfrac{1}{2}}(x-\stackrel{x_1}{(-4)}) \implies y +8= \cfrac{1}{2} (x +4) \\\\\\ y+8=\cfrac{1}{2}x+2\implies {\LARGE \begin{array}{llll} y=\cfrac{1}{2}x-6 \end{array}}\)

Answer:

(3,-9)

Step-by-step explanation:

The given equations are :

−5x−3y=12 (1)

y=x−12 ....(2)

Put the value of y from equation (2) in equation (1)

−5x−3(x-12)=12

-5x-3x+36 = 12

Taking like terms together

-5x-3x = 12-36

-8x = -24

x = 3

Put the value of x in equation (2)

y=3−12

y = -9

Hence, the solution of the above equations is x = 3 and y = -9 or (3,-9).

f(x) is an exponential function with an initial value of 33,966.17 and a decay rate of 0.310, which matches the trend of the data.

We can plot the data points and look for a pattern to see if an exponential or linear function better fits the provided data.

The provided data point can first be plotted as a scatter plot.

(1, 16890.32) (2, 14259.09) (3, 12001.57) (4, 10051.16)

To find the specific exponential function that would fit this data, we can use the formula for exponential decay:

f(x) = a * \(e^(-bx)\)

where f(x) is the value of the investment at time x, a is the initial value of the investment, and b is the decay rate.

Using the given data, we can plug in the values for f(x) and x to solve for a and b. Here is the calculation:

16,890.32 = a * \(e^(-b1)\)

14,259.09 = a * \(e^(-b2)\)

12,001.57 = a * \(e^(-b3)\)

10,051.16 = a * \(e^(-b4)\)

Dividing the second equation by the first, and the third equation by the second, and so on, we can get rid of the constant a:

14,259.09/16,890.32 = \(e^(-b)\)

12,001.57/14,259.09 = \(e^(-b)\)

10,051.16/12,001.57 = \(e^(-b)\)

Taking the natural logarithm of both sides, we get:

ln(14,259.09/16,890.32) = -b

ln(12,001.57/14,259.09) = -b

ln(10,051.16/12,001.57) = -b

Simplifying these equations, we get:

b ≈ 0.310

a ≈ 33,966.17

So the exponential function that best models this data is:

f(x) = 33,966.17 * \(e^(-0.310x)\)

This function has an initial value of 33,966.17 and a decay rate of 0.310, which matches the trend of the given data.

Step-by-step explanation:

We need to find g(f(2)). In order to do that, we have to first find f(2), and then take g of the answer. As we can see from the graph on the left, when x is 2, y is equal to 1 since (2,1) is on the graph. Therefore, f(2) is equal to 1.

Now, we have to find g(f(2)), which is g(1). As we can see from the graph on the right, the point (1,3) is on the graph. This means g(1) is equal to 3.

Therefore, our final answer is 3  

Answer:  is 3

Step-by-step explanation:

The answers that  best explains how we check to make sure that this condition is met is: c. Make sure there is similar spread around the sample mean of y.

The equal spread condition states that the residuals (differences between the actual and predicted values of y) should have roughly equal variance at each value of x.

To check if this condition is met, we examine the residual plot, which is a scatterplot of the residuals versus the independent variable x. If the spread of residuals around the mean is roughly equal for all x, then the equal spread condition is satisfied.

Therefore the correct option is C.

A polynomial is an expression in mathematics that consists of indeterminates (also known as variables and coefficients) that exclusively uses the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. x2 4x + 7 is an illustration of a polynomial of one uncertain x.

In both mathematics and science, polynomials are widely used. For instance, they are used to define polynomial functions, which can be found in a variety of contexts, from basic chemistry and physics to economics and social science, and they are used in calculus and numerical analysis to approximate other functions. Polynomial equations are used to encode a wide range of problems, from simple word problems to complex scientific problems.

Therefore, the surface represented by the given equation is a sphere centered at the origin with a radius of 6 units.

The given equation rho^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36 represents a surface in spherical coordinates. Let's break down the equation to identify the surface:

ρ^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36

Here, ρ represents the radial distance, φ is the polar angle, and θ is the azimuthal angle.

By analyzing the equation, we can see that it combines both the azimuthal and polar angles. The terms sin^2(φ)sin^2(θ) and cos^2(φ) involve both angles.

The equation ρ^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36 describes a sphere centered at the origin with a radius of 6 units. The constant value of 36 indicates that the squared radial distance from the origin to any point on the surface is 36.

Out of 90 reservation made, 77 diners are expected to show up. And the standard deviation of this binomial distribution is 3.39

We have been given that

   Percentage of people who make reservation and didn’t show up = 15%                       = 0.15

   Number of reservation made = 90

 Now we have to calculate number of people expected to show up that is we have to calculate mean. As this a binomial distribution in which we have been given

    n = 90   and q = 0.15  

Thus, µ = np = 90*(1-0.15) = 90*0.85

          µ = 76.5 ≈ 77

Thus it is expected to have 77 diners to show up.

Now standard deviation is given as:

To determine the best policy for Brennan Aircraft's plotter pen replacement, we can simulate the problem and compare the expected costs for both scenarios: replacing one pen or replacing all four pens each time a failure occurs.

Let's calculate the expected costs for each scenario:

Replacing one pen:

We'll calculate the expected cost per hour of plotter failure by multiplying the probability of each failure duration by the corresponding cost per hour, and then summing up the results.

Expected cost per hour = Σ(Probability * Cost per hour)

Expected cost per hour = (10 * 0.05 + 20 * 0.15 + 30 * 0.15 + 40 * 0.20 + 50 * 0.20 + 60 * 0.15 + 70 * 0.10) * $50

Expected cost per hour = $39.50

Replacing all four pens:

We'll calculate the expected cost per hour using the same method as above, but using the probability distribution for the scenario of replacing all four pens.

Expected cost per hour = (100 * 0.15 + 110 * 0.25 + 120 * 0.35 + 130 * 0.20 + 140 * 0.00) * $50

Expected cost per hour = $112.50

Comparing the expected costs, we can see that replacing one pen each time a failure occurs results in a lower expected cost per hour ($39.50) compared to replacing all four pens ($112.50). Therefore, the best policy for Brennan Aircraft would be to replace one pen each time a failure occurs.
