Answer:

Step-by-step explanation:
We are given that a function

We have to find the average value of function on the given interval [0,7]
Average value of function on interval [a,b] is given by

Using the formula

![f_{avg}=\frac{1}{7}[e^{\frac{x}{7}}\times 7)]^{7}_{0}](https://tex.z-dn.net/?f=f_%7Bavg%7D%3D%5Cfrac%7B1%7D%7B7%7D%5Be%5E%7B%5Cfrac%7Bx%7D%7B7%7D%7D%5Ctimes%207%29%5D%5E%7B7%7D_%7B0%7D)
By using the formula


Because 

Hence, the average value of function on interval [0,7]

Answer:
Step-by-step explanation:
Please use parentheses so that there's no question about what constitutes the argument of the sqrt function:
y=2 sqrt x+4 → y = 2√(x + 4)
This result is obtained from y = √x by:
1) translating the graph of y = √x 4 units to the LEFT, and
2) stretching the resulting graph vertically by a factor of 2.
Answer:


Step-by-step explanation:
Given

Required
Solve for x and for y

Add 31 to both sides


Solving for x
Subtract 4y from both sides


Divide by 2

Solving for y

Subtract 2x from both sides


Divide by 4

Split

Answer:
(j,l)
Step-by-step explanation:
It's the only combination left
It would take you 6 hours just have to divide 375 by 55 to get your answer :P
