It hits the ground at h=0
0=-16t^2-16t+96
undistribute -16
0=-16(t^2+t-6)
factor
0=-16(t-2)(t+3)
set to zero
0=t-2
2=t
t+3=0
t=-3, nope, we can't have negative time
at t=2, or 2 seconds
Circumference = 2*pi*radius
find the radius using this formula.
then use this formula => area of circle = pi*radius*radius
put the value of the radius that you get with the first formula to find the area
hope it helps you
The dimensions would be 7√2, 7√6 and 14√2.
A 45-45-90 triangle has two equal legs and a hypotenuse that is equal to the leg multiplied by the square root of two (t, t, t√2).
A 30-60-90 triangle has legs that are equal to t, t√3, and 2t.
The longest side on the 45-45-90 triangle will be 14√2. This will also be the longest side of the 30-60-90 triangle; this gives us
2t = 14√2
Dividing both sides by 2, we have
2t/2 = 14√2/2
t = 7√2
We now have t and 2t; we lack t√3:
t = 7√2
t√3 = 7√2(√3) = 7√6.
Answer:
0 + 1=0
