Please help. Question listed below
solmaris [256]

Answer:

f^{-1}(x) = ( \frac{9x-1}{8} )²

Step-by-step explanation:

f(x) = \frac{8\sqrt{x} +1}{9}

y = \frac{8\sqrt{x} +1}{9}

Solve equation for x

8√x + 1 = 9y

8√x = 9y - 1

√x = \frac{9y-1}{8}

(√x)² = ( \frac{9y-1}{8} )²

x =  ( \frac{9y-1}{8} )²

Switch "x" and "y"

y = ( \frac{9x-1}{8} )²

f^{-1}(x) = ( \frac{9x-1}{8} )²

Didn't get very far with the last question i asked but fr i need someones help. PLEASE.

Answer:

370000000=3.70000000\cdot10^8=3.7\cdot 10^8 \\ 7600=7.600\cdot 10^3

Step-by-step explanation:

Both numbers are integers (not fractions)

if you write an integer in scientific notation:

1) inset a comma between first and second digit (3.70000000)

2) calculate all digits on the right side of insetting comma (there are 8 digits after a comma: 7,0,0,0,0,0,0,0)

3) a fraction from point 1) you multiply by 10 to the power, which is equal to a number of digits after comma (8)

4) according this tips, you have 3.70000000\cdot 10^8

5) for a better notation, you may remove ending zeros

3.7\cdot 10^8
