Answer:
The first option ,f^-1(x)=1/2*x-1/2
Step-by-step explanation:
f(x)=2x+1
y=2x+1
Interchanging the places of x and y, we get,
x=2y+1
(x-1)/2=y
f^-1(x)=(x-1)/2
f^-1(x)=1/2*x-1/2
The first option.
Hello :
x : length y :<span> width
</span>xy = 50 ...(1)
x = 2y ...(2)
dubsct in (1) :

y = 5
x = 10
Answer: 379.94
Step-by-step explanation: To find the area of a circle, you do radius squared times pi. To find the radius, divide the diameter in half. So 22 divided by 2 is 11. 11 squared is 121. Then multiply 121 by 3.14. That equals to 379.94
