Answer:
27
Step-by-step explanation:
3 x 9 = 27
you just multiply the two. (if it asks for temperature after the hours just subtract)
The correct answer would be:
A) Sunbathers at a free suntan lotion booth on a popular beach were asked about their favorite suntan lotion.
-_-
If A=38x-x^2 then
dA/dx=38-2x
d2A/dx2=-2
Since the acceleration, d2A/dx2 is a constant negative, when velocity, dA/dx=0, it will be an absolute maximum for A(x)
dA/dx=0 only when 38=2x, x=19
A(19)=38(19)-19^2
A(19)=722-361
A(19)=361 ft^2
So the maximum possible area is 361 ft^2
(This will always be true as the maximum possible area enclosed by a given amount of material will always be a perfect square...)
Answer:
4x - 6
Step-by-step explanation:
6 less is -6
