Answer:B
Step-by-step explanation:
Let F be the primitive of f, i.e.

Then, we have

So, we have
![\displaystyle \int_0^5(2x-2)\;dx = \left[x^2-2x\right]_0^5 = 25-10=15](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cint_0%5E5%282x-2%29%5C%3Bdx%20%3D%20%5Cleft%5Bx%5E2-2x%5Cright%5D_0%5E5%20%3D%2025-10%3D15)
As for the sine, we can spare the integral: the sine is an odd function, which means that it is symmetrical with respect to the origin. Any odd function integrated over a symmetrical neighborhood of zero (i.e. any interval of the form [-n,n]) returns zero: by symmetry, there is an equal amount of positive and negative area. So, we have

Answer:
$1559.40
Step-by-step explanation:
1. Find the perimeter of the garden

2. Convert to feet
1 yd = 3ft
50 x 3 = 150
50 yd = 150 ft
3. Divide by 2.5 to find out how many sections are needed
150/2.5 = 60 sections
4. Multiply by 25.99
60 x 25.99 = 1559.4
It will cost $1559.40
