If Dakota lives 1,500 miles from school. She leaves for school walking at a speed of 60 meters per minuite. Write an equation for her distance D in meters from school after she walks for T minuites. How far is Dakota from school if she has been walking for 3 minuites?

Answers

Answer : R=1500−(60⋅t)
Explanation:
Total distance walked = 1500 meters.
Dakota's rate is 60 meters per minute.
The equation for distance walked over time = r⋅t .
Therefore the distance walked over time =
60 ⋅ t
The equation for distance remaining (let's call it R is 1500 −( 60 ⋅ t ). so the remaining distance to walk after a time t can be written as. "R = 1500 − ( 60 ⋅ t )

Answer:

Step-by-step explanation:

The formula for the volume of a cone is [tex]V =\frac{1}{3} \pi r^{2} h[/tex], where r is the radius of the base and h is the height.

In this figure, the cone's radius is 4 and the cone's height is 8.

Substituting in the values, we get:

[tex]V =\frac{1}{3} \pi (4)^{2} (8)[/tex]

Using 7 instead of 8 here would be a mistake, as 7 refers to the height of the cylinder below it.

Roller Coaster Crew

Ray and Kelsey have summer internships at an engineering firm. As part of their internship, they get to assist in the planning of a brand new roller coaster. For this assignment, you help Ray and Kelsey as they tackle the math behind some simple curves in the coaster's track.

Part A

The first part of Ray and Kelsey's roller coaster is a curved pattern that can be represented by a polynomial function.

1. Ray and Kelsey are working to graph a third-degree polynomial function that represents the first pattern in the coaster plan. Ray says the third-degree polynomial has four intercepts. Kelsey argues the function can have as many as three zeros only. Is there a way for the both of them to be correct? Explain your answer.

2. Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros.
g(x) = (x + 2)(x − 1)(x − 2)
g(x) = (x + 3)(x + 2)(x − 3)
g(x) = (x + 2)(x − 2)(x − 3)
g(x) = (x + 5)(x + 2)(x − 5)
g(x) = (x + 7)(x + 1)(x − 1)

3. Create a graph of the polynomial function you selected from Question 2.


Part B

The second part of the new coaster is a parabola.

4. Ray needs help creating the second part of the coaster. Create a unique parabola in the pattern f(x) = (x − a)(x − b). Describe the direction of the parabola and determine the y-intercept and zeros.

5. Create a graph of the polynomial function you created in Question 4.


Part C

6. Now that the curve pieces are determined, use those pieces as sections of a complete coaster. By hand or by using a drawing program, sketch a design of Ray and Kelsey's coaster that includes the shape of the g(x) and f(x) functions that you chose in the Parts A and B. You do not have to include the coordinate plane. You may arrange the functions in any order you choose, but label each section of the graph with the corresponding function for your instructor to view.

Answer:

See Explanation

Step-by-step explanation:

Part A

Ray and Kelsey are working to graph a third-degree polynomial function that represents the first pattern in the coaster plan. Ray says the third-degree polynomial has 4 intercepts. Kelsey argues the function can have as many as 3 zeros only. Is there a way for the both of them to be correct? Explain your answer.Ray and Kelsey are working to graph a third-degree polynomial function that represents the first pattern in the coaster plan. Ray says the third-degree polynomial has 4 intercepts. Kelsey argues the function can have as many as 3 zeros only. Is there a way for the both of them to be correct? Explain your answer.

Yes, they both can be correct. Ray is correct because you can have 4 intercepts. Only 3 can be zeros and 1 can be the Y-Intercept.

Part A - 2

Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros.

The zeros of function g(x)= x^3-x^2-4x+4 is -2,2, and 1. The other key features of polynomial functions include end behavior, Y- intercept and the axis of symmetry, and the vertex.

Provide a sketch of g(x), Label or identify the key features on the graph.

Part b

pART B

Ray needs help creating the second part of the coaster. Create a unique parabola in the pattern f(x) = ax2 + bx + c. Describe the direction of the parabola and determine the y-intercept and zeros.

The direction of the parabola would be both sides going up because they are the leading coefficient and the degree is both even and positive numbers. The zeros are 1.5 and -2. The Y-intercept is 6

The axis of symmetry is -1.75 and the vertex is 1.75 and 12.37

X= B/2A

X=7/2(2)

X= 1.75

2x^2+7X+6

2(1.75)^2+7(1.75)+6

2(-3.06)-12.25+6

-6.12-12.25+6

=12.37

The safety inspector notes that Ray also needs to plan for a vertical ladder through the center of the coaster's parabolic shape for access to the coaster to perform safety repairs. Find the vertex and the equation for the axis of symmetry of the parabola, showing your work, so Ray can include it in his coaster plan.

Create a graph of the polynomial function you created in Question 4.

TOPIC 3

part c

Now that the curve pieces are determined, use those pieces as sections of a complete coaster. By hand or by using a drawing program, sketch a design of Ray and Kelsey's coaster that includes the shape of the g(x) and f(x) functions that you chose in the Parts A and B. You do not have to include the coordinate plane. You may arrange the functions in any order you choose, but label each section of the graph with the corresponding function for your instructor to view.
