First you have to find 20% of $8. you have to convert 20% into a decimal and multiply that by 8 which would be 1.6. then, add that to the $8. your answer would be $9.60.
The height of water increases by 2 inches per minute option first "The height of the water increases 2 inches per minute" is correct.
<h3>What is the slope?</h3>
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

We have given a table:
Time height
2 8
4 12
6 16
8 20
10 24
The slope of the line = (12-8)/(4-2) = 4/2 = 2
The value of the slope is positive we can say, the height of water increases as time passes.
Thus, the height of water increases by 2 inches per minute option first "The height of the water increases 2 inches per minute" is correct.

so your answer would be
-11b^2+8b-4
