Tan(angle) = opposite leg/ adjacent leg
Tan(30) = x/22
X = 22 * tan(30 )
X = 12.701 feet.
Round as needed
Your taking off $20 from the amount that you have to begin with
This is hard in mathematical language, but there is only this way to present it. Let us denote by A the consentration of the substance and by A' its rate.
We have that b/A= t+c where c is a constant.
Hence A=b/(c+t)
By differentiating, we get that A'=-b/(C+t)^2
Then, we have that -(A)^2=A'/b
Hence at any point, we have that if we make the concentration 17 times, we have that there is a 17 times bigger , the rate will become bigger by 17*17, hence 289 times faster.
