Question

PRECALC AB

Answer 1

Answer:

So, the original amount was 58 ounces , then in 15 secs, we get 28, So the amount we lost was 30 by 15, giving us the slope of 2 ounces lost per second. Now that we know the slope, we can answer the questions

A.  We can get the equation by finding the y int. (below) and writing it as y=-2x+68

B. Since we lost 2 ounces per second, we need to add up 2 ounces for every second lost. 2x5=10+58= 68 ounces at the beginning.

C. Since we have the formula and the slope, we just need to find when y hits 0. and that is: After 34 seconds.
