For this case we have the following equation:
h = -16t2 + 64t + 80
To find the maximum height, we derive the equation:
h = -32t + 64
We match zero:
-32t + 64 = 0
We clear t:
t = 64/32
t = 2
We substitute the value of t in the given equation:
h (2) = -16 * (2) ^ 2 + 64 * (2) + 80
h (2) = 144
Answer:
The maximum height is 144 feet and the time to reach this height is 2 seconds.
You have the opposite and the hypotenuse given. So you use the sine ratio
Sin x = 6/9
x= sin inverse of 6/9 = 41.8 degrees
Basically you just divide:
123/3 = 41
So the sale price of the coat would be $41
Answer:
$27 000
