Answer:
16 ft/s²
Step-by-step explanation:
s(t) = sin(t) - 4cos(2t)
Differentiation for v
v(t) = cos(t) + 8sin(2t)
Differentiate for a
a(t) = -sin(t) + 16cos(2t)
At t = π
a(π) = -sin(π) + 16cos(2π)
= 0 + 16
= 16
Answer:

Step-by-step explanation:
We have been given an equation
. We are asked to find the zeros of equation by factoring and then find the line of symmetry of the parabola.
Let us factor our given equation as:

Dividing both sides by 2:

Splitting the middle term:




Using zero product property:



Therefore, the zeros of the given equation are
.
We know that the line of symmetry of a parabola is equal to the x-coordinate of vertex of parabola.
We also know that x-coordinate of vertex of parabola is equal to the average of zeros. So x-coordinate of vertex of parabola would be:

Therefore, the equation
represents the line of symmetry of the given parabola.
ANSWER: Yes, because 52:4 = 13
