What triangle? Is there one on here?
A = 1/3 * s^2 * h where s is a side of the base and h is the height.
Answer:
(-a,b)
Step-by-step explanation:
You use midpoint formula which is (x1+x2/2),(y1+y2/2)
The ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.
<u>Explanation:</u>
We need to find the time at which the ball will be at height 19 feet.
Equation:
h = 3 + 34t - 16t²
19 = 3 + 34t - 16t²
16 = -16t² + 34t
-16t² + 34t - 16 = 0
On solving the equation, we get
t1 = 0.7 s and t2 = 1.42s
Therefore, the ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.
