I suppose you mean to have the entire numerator under the square root?

We can use a trigonometric substitution to start:

Then for
,
; for
,
. So the integral is equivalent to

We can write

so the integral becomes

Step-by-step explanation:
X + 7x = 56 + 8
Simplifying x + 7x = 56 + 8 Combine like terms: x + 7x = 8x 8x = 56 + 8 Combine like terms: 56 + 8 = 64 8x = 64 Solving 8x = 64 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Divide each side by '8'. x = 8 Simplifying x = 8
Answer:
When the number of sessions is equal to 10, the total cost is the same in the two plans
Step-by-step explanation:
Let
y ---> the total cost
x ---> the number of sessions
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
Planet Fitness
we have
The slope is equal to

The y-intercept or initial value is equal to

substitute
----> equation A
Gold's Gym
we have
The slope is equal to

The y-intercept or initial value is equal to

substitute
----> equation B
Equate equation A and equation B

solve for x

therefore
When the number of sessions is equal to 10, the total cost is the same in the two plans
