Shen started to run on a treadmill after setting its timer for 93 minutes. The display says that he has finished 69% of his run.

djverab [1.8K]

Answer:

64.2 minutes

Step-by-step explanation:

We are given that

Shen set timer to run=93 minutes

He has finished his run=69%

We have to find total number of minutes have gone by.

69% of 93

= $\frac{69}{100}\times 93$

By using

a% $=\frac{a}{100}$

69% of 93= $\frac{6417}{100}$

69% of 93=64.17 min

69% of 93 $\approx 64.2min$

Hence, 64.2 minutes have gone by.

What is the inverse function of y=x^2-7

Vikentia [17]

With inverse functions you just swap 'x' and 'y' and solve for 'y'.

$\sf y=x^2-7$

Swap 'x' and 'y':

$\sf x=y^2-7$

Add 7 to both sides:

$\sf x+7=y^2$

Take the square root of both sides:

$\sf y=\boxed{\sf\pm\sqrt{x+7}}$
