Answer:
a) 8²
b) 2⁴ and 5⁴
Step-by-step explanation:
The power of a number is the base together with the exponent of the number.
The given expresion is
We can rewrite this as:
Over here the power being multiplied is
Also, the powers being multiplied in
are 2⁴ and 5⁴
Answer:
- 0.7 m/s
Step-by-step explanation:
Because we are talking about "elevation", we assume that going upwards will result in a positive elevation change and going downwards will result in a negative elevation change.
We also assume, since we are talking about free-diving, that he starts from the surface (i.e elevation 0 m) and he free dives to a distance of 42 meters downwards (i.e elevation of -42)
In our case, the change in elevation
= final elevation - intital elevation
= -42 - 0
= -42 m
time elapsed is given as 60 sec.
Hence rate of change of elevation
= change in elevation ÷ time elapsed
= -42 ÷60
= - 0.7 m/s
Answer:
im pretty sure that it is B?
Step-by-step explanation:
Answer:
h = 440.94 feet
Step-by-step explanation:
It is given that,
An architect is standing 370 feet from the base of a building, x = 370 feet
The angle of elevation is 50°.
We need to find the approximate height of the building. let it is h. It can be calculated using trigonometry as follows :
So, the approximate height of the building is 440.94 feet
