Answer:
The value of
is
.
Step-by-step explanation:
We know that the position function is given by

Velocity is defined as the rate of change of position. Therefore,

So, the velocity function is

When a body reaches a vertical velocity of zero, this is the maximum height of the body and then gravity will take over and accelerate the object downward. Thus,

We know that the ball bearing reaches its maximum height 21 seconds after being launched (t = 21 s).
So, the value of
is
.
Answer:
A = arctan(BC/CA) = arctan(8/2) = 75.96 deg

50 degrees because 50+50= 100 +80 = 180 and there is 180 degrees in a triangle
Answer:
c. 1,417
Step-by-step explanation:
200,000 (8.5%) = 17,000
17,000 / 12 = 1,416.67 or 1,417
1220/8= 152.5
So 8 can go into 1220 152.5 times
