The equation of motion is
s(t) = (1/2)a·t² +v₀·t +s₀
where a is the acceleration, v₀ is the initial velocity, and s₀ is the initial position.
For t in seconds and s(t) in feet, your values make this equation be
s(t) = 5t² -20t +8

Let , missing value(_)=A
As, it is given that ,

To convert the value of A into Radians,
360°=2 π Radians

So, missing value to the nearest hundredth= 1.26 Radians
Answer:
A
Step-by-step explanation:
Given
-4x²(5
- 3x² + x - 2)
Multiply each term in the parenthesis by - 4x²
= - 20
+ 12
- 4x³ + 8x²
