a particle moves along the x-axis so that its position at time t is given
by x(t) = x2 – 7t + 12. for what value of t is the velocity of the par-
ticle zero?
(a) 2.5
(b) 3.
(c) 3.5
(d) 4
(e) 4.5

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
