Answer:
58 square feet
Step-by-step explanation:
The room is already broken down into two smaller rectangles.
The smaller of the two measures 4 ft by 2 ft. , so substitute 4 for
and 2 for
.
(smaller rectangle)
, or
.
(smaller rectangle)
The larger measures 10 ft by 5 ft, so using the same method, multiply times
.
(larger rectangle)
, or
.
(larger rectangle)
Add the two rectangles' areas together to find the total area of the room.
8 + 50 = 58
Answer:
f(x) = 3x⁴ - - 17x +
Step-by-step explanation:
To find f'(x), we will follow the steps below:
We will start by integrating both-side of the equation
∫f'(x) = ∫(12x^3 - 2x^2 - 17)dx
f(x) = 3x⁴ - - 17x + C
Then we go ahead and find C
f(1) = 8
so we will replace x by 1 in the above equation and solve for c
f(1) = 3(1)⁴ - - 17(1) + C
8 = 3 - - 17 + C
C =8 - 3 + 17 +
C = 22 +
C =
C =
f(x) = 3x⁴ - - 17x +
