I have no idea
just so you know. i most likely answered this because i would like the points
Answer:
Step-by-step explanation:
6*8+(12-4)/2 = 0
(12-4)/2+48 = 0
8/2+48 = 0
4+48 = 0
52 = 0
L <> R
Since x dollars is the total monthly sales Paul makes when his sales exceed 20,000 dollars, then the function f(x) should add x dollars and $20,000. The answer is B. x+20,000.
Assuming that x dollars is still the sales after gaining $20,000, then 15 percent of x is modeled by B. 0.15x.

Hooke's law states that F = -kx, so
<span>k = - F/x = - ma / x = - 2.6kg · (-9.8m/s²) / (0.041m) = 621 N/m ← (a) </span>
<span>(b) f = (1/2π) · sqrt(k/m) = (1/2π) · sqrt(621N/m / 2.6kg) = 2.46/s = 2.46Hz </span>
<span>Amplitude is simply 2.1cm</span>
