Answer:
Step-by-step explanation:
hello
so to know the maximum to y we can check the maximum of
f(x)=
f is derivable and f'(x)=6-2x
f'(x)=0 <=> x = 3
so the maximum is reached for x = 3
f(3)=18-9=9
and then
to be rigorous, we can write the variation table of y to show that there is only one maximum
hope this helps
2 x 3 - (2-10) + (2 x 4) =
6 - (-8) + 8
6 + 8 + 8 = 22
So the answer would be g, 22.

D
Step-by-step explanation:
If the number is a repeated decimal it is irrational. If it does not repeat and stops it is rational. :)
Answer:
216 in^2
Step-by-step explanation:
a= h x b /2
= 24in x 18in / 2
= 216inches^2
Answer:
x= 8
y = 21
Step-by-step explanation:
27 + 3y = 90
3y = 90 -27
y = 63/3
y = 21
x+ 90 +8x+18 = 180. { linear pair}
9x +108 = 180
9x = 180-108
x= 72/9
x = 8
