Answer:
6
Step-by-step explanation:
Your function is split into 4 parts.
We want to use the piece that includes x=6.
This only included in the inequality that says x is greater than or equal to 5. Since that is, we use the expression that corresponds to that to find f(6).
f(6)=2(6)-6
f(6)=12-6
f(6)=6
Parametize C of the line integral as

from 0<=t<1 then

which means by substituting x with e^t and y with and dx with e^t dt we get

by adding exponents

7 & 13 have an odd product.
Hope this Helps!!
Answer:
up or down over left or right to the next point
Step-by-step explanation:
Using the Pythagorean theorem 4 would be the height and 8 would be the hypotenuse, you need to find the base
4^2 + X^2 = 8^2
16 x x^2 = 64
x^2 = 64-16
x^2 = 48
x = sqrt(48) = 6.92 feet ( round answer as needed )
