Answer:
in
Step-by-step explanation:
The formula to find the area of a circle: 
, where 
is the radius.
The formula to find the circumference (perimeter) of a circle: 
, where is the radius.
1) To find the circumference of the circle, we need to find the radius () first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.
Cancel the 
by bringing it to the other side.
÷
2) Find the circumference of the circle by using the formula, .
=

Answer:
x = 4 , y = ⅕
Step-by-step explanation:
2x + 5y = 9 (1)
3x - 5y = 11 (2)
Add (1) and (2)
5x = 20
x = 4
Using (1), find y
2(4) + 5y = 9
5y = 1
y = ⅕
The inverse of the function x^7 is x^-7 and it is also a function.
An inverse function or an anti function is defined as a function, which can reverse into another function.
A standard method to find inverse of a function is to set y=f(x)
let y= f(x)=x^7
thus
![\sqrt[7]{y}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7By%7D)
=x
thus 
(y)=
thus ![f^{-1} (x)=\sqrt[7]{x}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%28x%29%3D%5Csqrt%5B7%5D%7Bx%7D)
(To verify this if a function is inverse or not we are required to check for the identity)
f((x))=(f(x))=x
Therefore, The inverse of the function x^7 is x^-7 and it is also a function.

Answer:
I believe it is linear
Step-by-step explanation:
because if you are talking about percentage then it should be done on a linear graph so therefore i believe the answer is linear..................if i am incorrect i am very sorry but i believe i am correct.
Answer:
a) The present value is 688.64 $
b) The accumulated amount is 1532.60 $
Step-by-step explanation:
<u>a)</u><u> The preset value equation is given by this formula:</u>
where:
- T is the period in years (T = 10 years)
- r is the annual interest rate (r=0.08)
So we have:
Now we just need to solve this integral.
The present value is 688.64 $
<u>b)</u><u> The accumulated amount of money flow formula is:</u>
We have the same equation but whit a term that depends of τ, in our case it is 10.
So we have:
The accumulated amount is 1532.60 $
Have a nice day!
