t = time
Multiply the acceleration by time and add to the height:
The equation becomes H(t) = -16 * t^2 + 90
set h(t) to 0
0 = -16*t^ +90
Subtract 90 from both sides:
-90 = -16*t^2
divide both sides by -16:
t^2 = -90 / -16
t^2 = 5.625
t = √5.625
t = 2.37 seconds, round to 2.4 seconds.
Answer:
Step-by-step explanation:
Start with the given
Divide the two on both sides to get
I think it’s an equilateral triangle meaning all sides are the same so:
2x+2x+2x= 180 (that’s how much a triangle is)
6x=180 divide both sides by 6
x= 30
each side is 60 degrees
I believe that the answer is, D.
I think this because 1.8 is greater than -66%, -66% would be last i believe. I think -66% is least out of all of them.
Hope this helps ya.
