Which value is needed to create a perfect square trinomial from the expression x2 + 8x + _____?

1 answer:

4 0

I believe it's +16, if you complete the square you'd have (x+4)^2 - 16 + a = 0 where a is the value you're looking for, so to make this correct you need a = 16

(3, - 2)

given y = - 2, then

- 2x + 4 = - 2 ( solve for x )

subtract 4 from both sides

- 2x = - 6 ( divide both sides by - 2 )

x = $\frac{-6}{-2}$ = 3

Given the following acceleration function of an object moving along a line, find the position function with the given initial ve

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 $s(t)=-12t^2$ .
