Answer:
After 4s
Step-by-step explanation:
Given the ball is initially projected upwards with a velocity of 64ft per sec and we are required to find the time at which it reaches the ground .There are many approaches to solve this problem we will follow this one:
It is also known as the time of flight for the ball which can be found by doubling the time taken for the ball to reach to its maximum height or the point where velocity is zero.
Now 
For the time taken to reach the max height 
.
Which implies that -32t+v=0.
∴Time taken to travel halfway through the path =2sec.
∴total time =
Answer:
y = C/h - 2
Step-by-step explanation:
Equation
C = (2 + y)*h
Solution
C = (2 + y)*h Divide by h
C/h = (2 + y)*h/h
C/h = 2 + y Subtract 2 from both sides
C/h-2 = 2-2+ y Combine
C/h - 2 = y
Answer:
$360
Step-by-step explanation:
I am pretty sure this is the answer i am not that sure. But $9,000 at 8% is 760
and 360 is half of 760
Answer:
The answer is 8.91 or 8.9
Step-by-step explanation:
SInce the circumference is 56, you'll divide it by pi or 3.14. It's as if you're doing it backwards, but not always. After you divide it by 3.14, you'll get your diameter, or in this case, 17.8. Divide the diameter by 2 because the diameter is twice the radius. Eventually your final answer will be 8.91 or 8.9
