The temperature drops 22<span>°F in 15 minutes.
22</span>°F / 15 = 1.46<span>°F per minute
Hope I helped!</span>
Differentiate each term with respect to x , then solve y'.
dy/dx = y+2x^3/ x(1+x)
<span>a = 1/2 x b x h
h = 3b
so 1/2 x b x 3b = (1/2)(3b^2) = 150
(150 x 2)/3 = b^2
100 = b^2
b = square root of 100 = 10
h = 3b = 3 x 10 = 30</span>

V = d/t = 8.8 miles/[80/60] hours = 6.6 miles/hour
t = d/v = d/6.6
Answer: d/6.6, where d is the number of miles to run.
