What is the area of the sector bound by the center of the circle and arc CD in the circle below? (1 point) Circle A is shown wit
1 answer:
Answer:
19.54 square feet.
Step-by-step explanation:
The Area of sector of any circle can be calculated by the formula :
Area=÷360
Where alpha is the angle made at center of the circle.
In the given question r=8 ft and angle made at center alpha = 35 degrees.
Substituting these values in the formula Area=
(Substituting π=3.14)
Answer:19.54 square feet.

Answer:
This is the same as writing 7*Ln( e^(2x) + 10) + C
=======================================================
Explanation:
Start with the equation
Apply the derivative and multiply both sides by 7 like so
The "multiply both sides by 7" operation was done to turn the 2e^(2x) into 14e^(2x)
This way we can do the following substitutions:
Integrating leads to
Be sure to replace 'u' with e^(2x)+10 since it's likely your teacher wants a function in terms of x. Also, do not forget to have the plus C at the end. This is a common mistake many students forget to do.
To verify the answer, you can apply the derivative to it and you should get back to the original integrand of
