Answer:
The maximum height is:
The ball reaches the ground in 1.79 s.
Step-by-step explanation:
We need to take the derivative and equal to zero to find the time at the maximum height.
(1)
Now, we just need to put t(max) into equation (1) to find h(max)
If we want to get the time when the ball reaches the ground we just need to equal h(t) to zero.
Let's solve this quadratic equation.
We will get two solutions and we must choose the positive value.
t1 = 1.79 u
t2 = -0.10 u
Therefore, the ball reaches the ground in 1.79 u.
I hope it helps you!
Answer:
A. (2(4x+7x))=P
B. 2(4(3)+7(3))=2(12+21)=2(33)=66
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
40 because since we know c is 25 and b is 65 we have to subtract 25 from 65 and get 40
AB = 15
Since both sides are the same you can match both of the equations and solve for X which in this case is 3. So 4 * 3 = 12 + 3 = 15 and 5 * 3 also is 15 which makes it true since they are the same triangle.
