The answer is r to the 14th power.
Answer:
<em>3.94 seconds </em>
Step-by-step explanation:
h = - 16t² + 248
If stone is dropped, then h = 0
- 16t² + 248 = 0
t² =
t = ±
t < 0 is a solution of equation, but not a solution of the task
t = ≈ <em>3.94 seconds</em>
Answer:
Step-by-step explanation:
hello :
A= πr² r = 6
so : A= 3.14(36) = 113.04
Knowing base angles theorem, we know that if the triangle is isosceles, then the bottom base angles and congruent. That means that, we must subtract 80 from 180 and then divide the number by 2, since we must find 1 base angle. This brings us to the answer, 50 degrees.
