Answer:
226
Step-by-step explanation:
it's because I did addition
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.
He had $5,000,000 in CD sales; $3,300,000 in video sales; and he earned $1,245,000 in royalties.
1,000,000 CDs * $5 each = $5,000,000
550,000 videos * $6 each = $3,300,000
Total sales = 5,000,000+3,300,000 = 8,300,000
15% royalties = 0.15(8,300,000) = 1,245,000
