The function is defined as

This means that, taken an input m, the output is the input squared, plus 7.
So, if we take the input -4, we square it to get 16, and we add 7 to get 23.
Answer:
The scale factor used is 0.4
Step-by-step explanation:
Given


Required
Determine the scale factor of RST
The question can be solved using scale factor formula
Scale factor is calculated as thus;

In this case; R' is the new length and R is the old length

Substitute the values of R and R'

Factorize the denominator



<em>Hence, the scale factor used is 0.4</em>
826140 is read 'Eight hundred twenty-six thousand, one hundred and forty'
826140 = 800000 + 20000 + 600 + 100 + 40
The value of 8 is 800000 [Eight hundred thousand]
7,200 = (24)(20)h
15=h (just divide)
To check, 20*24*15 = 7,200 cubic centimeters so 15 cm is right
