Find the inverse of the function.

Mathematics
1 answer:
liq [111]3 years ago
3 0

Answer:

The option 'b' is true.

Step-by-step explanation:

Given the expression

f\left(x\right)=\frac{2}{x+7}

A function g is the inverse of the function f if for y=f(x), x=g(y)

y=\frac{2}{x+7}

Replace x with y

\:x=\frac{2}{y+7}

solve for y

y=\:\:\frac{2}{x}-7

Thus,

f^{-} (x)=\frac{-7x+2}{x}

Therefore, option b is true.

Lucy borrowed $425 from Colleen. Colleen charges Lucy 5.3% interest if Lucy pays Colleen back in 3 years how much does she pay C
Sonja [21]

Answer: Lucy pays $ 492.58  back altogether.

Step-by-step explanation:

Formula : Interest = Principal x Rate x Time

Given: Principal  = $425  , rate = 5.3% = 0.053 , time = 3 years

Interest = 425 x 0.053 x 3 ≈ $ 67.58

Total amount need to pay back = Principal + Interest

= $ (425+67.58)

= $ 492.58

Hence, Lucy pays $ 492.58  back altogether.

Could you guys help me find the area of these please? i don't understand how to do this
vova2212 [387]

Answer:

for 9, the answer is 246.49

Step-by-step explanation:

This is area of a circle correct?

The formula is PI x radius squared.

3.14 x the radius, which is 5, squared

I am re-editing this

so sorry the answer is actually 78.54

The reason why it is 78.54 is that you need to square the radius before multiplying with PI.
