Nezavi [6.7K]

Answer:

Position function is s(t)=-12t^2

Step-by-step explanation:

Given a(t)=-24, since velocity is the antiderivative of acceleration, then v(t)=-24t.

Also, since position is the antiderivative of velocity, then s(t)=-12t^2.

C. Write an equation of the line that contains the given point and has the given slope. Write the equation in slope intercept fo
Harlamova29_29 [7]

Answer:

Step-by-step explanation:

For the first problem, we can plug in the slope of -5 for m:

y = -5x + b

To solve for b, we plug in the given point (-2, 2):

2 = -5(-2) + b

2 = 10 + b

b = -8

This gives us the equation:

y = -5x -8

For the second problem, we can plug in the slope of 1 for m:

y = x + b

To solve for b, we plug in the given point (0, -2):

-2 = 0 + b

b = -2

This gives us the equation:

y = x - 2
