Answer:
5
Step-by-step explanation:
Whenever you multiply square roots that have the same number inside the radicand, you get the number under the radicand. For example, the square root of 4 squared will equal four. Similarly, you are simply squaring the square root of 5, so you should get 5 as your answer.
Answer:
x = 3
Step-by-step explanation:
since they are similar use these ratios
x/9 = 1/3
do cross multiplication
9*1 = 3*x
9/3 = x
3 = x
Answer: the volume is 10.5
Step-by-step explanation:
V=lwh
V= 4 x 3/4 x 3.5
V = 4 x 2.625
V = 10.5
Answer:
• mathematical: y ≤ 52
• reasonable: 0 ≤ y ≤ 52
Step-by-step explanation:
The reasonable range is the set of heights between the maximum height and the ground (y=0).
___
The maximum height is about 44.51 meters, so values between that and 52 meters are not in the reasonable range. A maximum height of 52 meters requires an initial velocity of about 15.4 m/s.
