Write a function to describe the following scenario.

yKpoI14uk [10]

Answer:

$r=160-12m$

Step-by-step explanation:

Heart rate will be represented by $r$ , minutes will be represented by $m$ .

Here's the equation I came up with:

$r=160-12m$

We can also rearrange it to look like a point-slope equation. Either way works, it's the same equation.

$r=-12m+160$

This works because her heart rate is decreasing by a constant value. The initial heart rate is like the y-intercept, while the amount that it decreases by is the slope.

I hope this helps!

the square root of 4,356 is an integer. without a calculator , determine what the integer is by eliminating possibilities.

Zanzabum

It's more than 3600, so its greater than 60.
it's less than 4900, so its less than 70.
a no.'s root can end with six if the no. ends with 4 or 6.
so the no is either 64 or 66.
Now if it's 66, the square must be greater than sq of 65.
65 sq= 4225
the given no. is greater than sq of 65.
Therefore the number is 66.
