8.5? Give that a try!:)
What I did was I took a piece of paper, and listen those numbers from least to greatest, then I scratched off one number per side, till I got to the middle. From there, I added 8 and 9, the divided by 2. There, I got 8.5

Answer:
x = 20
y = 70
Step-by-step explanation:
Solve for x:
5x - 20 = 3x + 20
2x - 20 = 20
2x = 40
x = 20°
Solve for y:
x + y = 90°;
(20) + y = 90°
y = 90 - 20
y = 70°
Hope this helps!

Rates of change are the change of a quantity over another.
The rate of change of the mass position at 2.1 seconds is -89.6 cm/ s
The given parameters are:
-- the amplitude
--- the period
The position of the mass is modeled by:
Where:
So, we have:
becomes
Differentiate
When t = 2.1, we have:
Approximate
Hence, the rate of change of the mass position at 2.1 seconds is -89.6 cm/ s
