Answer:
Step-by-step explanation:
4y2 - 2x + 7 + 2y for x = 7 and y =2.
= 4(2)^2 -2(7) +7 + 2(2)
= 4(4) - 14 +7 + 4
= 16 - 14 + 7 + 4
= 13
The answer is:

Formula for "S.A." (Surface area) of a cylinder
S.A.
= 2
r² + 2
* r * h ;
_______________________________________in which "r" = length of radius of circle at the end; and "h" = "height" ;
__________________________________________Given: r = 2 m ; and h = 3 m ;
__________________________________________ We can "plug in" these given values; and solve for the "surface area" in terms of
"
" .
____________________________________________S.A. = 2
r² + 2
* r * h ;
= 2
* (2)² + 2
* (2) * (3) ;
= 2
* (4) + 2
* (6) ;
= (8
) + (12)
= 20 m² ._______________________________________
Answer:
The quotient rule means dividing
Step-by-step explanation:
"The quotient rule says that if we have exponents with the same base being divided, we can just subtract the exponents. Ultimately this is about <u>dividing</u> exponential expressions."
That curve represents a cardioid.
Answer:
x = 69
Step-by-step explanation:
Given
35 + x + 76 = 180, that is
x + 111 = 180 ( subtract 111 from both sides )
x = 69
