Answer:
A). interval 0 ≤ x ≤ 2
B). interval 2 ≤ x ≤ 4
C). interval 8 ≤ x ≤ 10
D). h(14) = 0
Step-by-step explanation:
Part A.
In the interval 0 ≤ x ≤ 2, height of the water balloon is increasing.
Part B.
In the interval 2 ≤ x ≤ 4, height of the water balloon is constant.
Part C.
In the interval 8 ≤ x ≤ 10, height of the water balloon is decreasing the fastest.
Slope of the line between x = 8 and x = 10 is the maximum.
Part D.
Since at x = 10 height of the water balloon is h = 0, therefore, at any moment after x = 10 seconds height of the balloon will remain zero.
No. Only moths because they are cool
Answer:
20
Step-by-step explanation:
We know that ΔBAC and ΔBED are similar becuase of the AA Postulate (they both have a right angle and they both share ∠B). Since AC is 15/3 = 5 times longer than ED, the scale factor is 5 which means AB is 5 times longer than EB. This makes EB = 25 / 5 = 5. Since AB = AE + EB and we know that AB = 25, AE = x and EB = 5, 25 = x + 5 which means x = 20.
