Answer:
E. Definition of Supplementary Angles
Step-by-step explanation:
9x^3-6x^2+3x
Basically with this you just wanna simplify each term one-by-one.
For instance, look at the first term, 27x^4
Imagine 27x^4/3x
3 goes into 27 9 times, and x goes into x^4 4 times (cuz x to the power of 4 is just x times x times x times x)
So you’re left with 9x^3
Answer:
C
Step-by-step explanation:
Since the circle is inscribed inside of the square, its diameter is the same as the side length of the square, or 8. This means that the radius is 8/2=4. The formula for the volume of a circle is 
, or in this case 
. The area of the square is 8*8=64 square feet. 50.24/64 is equal to 78.5%, or answer choice C. Hope this helps!
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
