Answer:
See below in bold.
Step-by-step explanation:
A). s(t)= -16t^2+64t+200
Converting to vertex form.
s(t) = -16 (t^2 - 4t) + 200
s(t) = -16 [(t - 2)^2 - 4] + 200
s(t) = -16(t - 2)^2 + 64 + 200
s(t) = -16(t - 2)^2 + 264
The maximum height is after 2 seconds and it is 264 feet.
B) The ball hits the ground when s(t) = 0 so we have:
-16t^2+64t+200 = 0
x [-64 +/- sqrt (64^2 - 4*-16*200) ] / -32
x = 6.06, -2.06
So the answer is 6.06 seconds.
-1(18+4x)=8
Then you distribute
-18-4x=8
-4x=26
X= -6.5
Thats a tough one :/ good luck
Answer:
Center (7,2); Radius - Square Root of 10
Step-by-step explanation:
Equation for a Cricle:
(x−h)^2 + (y−k)^2 = r^2
Where:
h = x-coordinate of the center of the circle
k = y-coordinate of the center of the circle
r = radius of the circle
For this problem, your h = 7, k = 2, and r = square root of 10
