Answer:
D
Step-by-step explanation:
The degree of a polynomial is determined by the largest exponent of a term within the polynomial.
Given
7x³ + 4x - 5 + 8
The term with the largest exponent is 8
with exponent 5
Thus the polynomial is of degree 5 → D
if we take £15837.77 to be the 100% and we increase it by 18.5%, that'll be 100% + 18.5% = 118.5%.

Answer. the answer for the problem you asked is A
Answer: x-bar = y-bar = 0 whereas z-bar = 8/3
M= (c^2)/8 which is intern equal to 2
Step-by-step explanation:
Find the area, by setting the limits as
= 



Therefore;
Mxy= 
z-bar = 8/3
M= 8
dividing it into two volume gives us = 4
means 

c=2
Answer:
81x^4/16 (81x to the fourth over 16)
Step-by-step explanation:
First you apply the exponent rule: (a/b)^c -> a^c/b^c
So it looks like this: 3x^2/4^2
Then you apply the exponent to the whole thing, and 3^4 is 81, x^4 stays like that, and 2^4 is 16
You can't simplify any more after that so that's your answer
Hope this helps!
