For what values of the variable does the following expression make sense:
square root of 8c

Step-by-step explanation:

Given:

The given expression is:

A square root function always gives a result greater than or equal to 0.

For a square root function, the terms inside the square root must be greater than or equal to 0. Therefore,

Dividing both sides by 8 to isolate 'c', we get:

Therefore, the values of 'c' must be greater than or equal to 0 for the given square root function to exist. If the values of 'c' less than 0, then the square root function is undefined and doesn't give real values as result.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
