Answer: (4, -3)
Step-by-step explanation:
First turn them into slope intercept form:
y=3x-15
y= -1x+1
then I used a calculator that graphs them for me
N - 6 = 15
I’m not sure if this is exactly what you’re asking for but I’m positive that this is the answer
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.
