You know
Squaring both sides gives
Then raising both sides to any integer power 
gives
That is, any power of 
where the power is a multiple of 4 will always be equal to 1.
So
But perhaps you mean to write 20+1 as the exponent, in which case
The answer for plato is C The<span> expression (1.09)x reveals the approximate rate at which the files are corrupted per minute.</span>
The expression for (r-s)(x) is found by subtracting s from r. That difference is
. The expression for (r+s)(x) is found by adding them, which is
. Now we are told to evaluate (r*s)(x) which means they want us to multiply those and state the "new" expression that results.
. There you go!
I don't know domain but range is the smallest number and largest number, median is the middle number when the numbers are ordered from least to greatest, and the mode is the most common or reoccuring variable in a set of numbers.
The answer to this question is letter C
We can approach this by first finding the rate of feet per second traveled.
240(feet)/30(seconds)= 8 feet per second.
This answer resembles the slope for answer choice C.
To find the distance traveled in 10 seconds we do 10*8= 80 feet.
I hope this helps, please like and brainliest if correct, thank you!
