Question

can someone please explain this to me?

Answer 1

\[\frac{d}{dx}\int_a^b f(x)dx = F(b)-F(a)\]

Answer 2

\[f(x) = R(t) = 2+\cos\left(\frac{\pi t}{11}\right)\]

Answer 3

can someone pleaseee do the problem with me cause i really dont understand this

Answer 4

okk

Answer 5

wait so i just put in 0 for t?

Answer 6

no do not integrate, that is already a function in gal/hr, use that and plug in the value for house

Answer 7

hours

Answer 8

You could just evaluate at R(6) - R(0)....

Answer 9

^ yep

Answer 10

\[\frac{d}{dx}\int_a^b f(x)dx = F(b)-F(a) = \left. 2+\cos\left(\frac{\pi t}{11}\right) \right|_0^6=~?\]

Answer 11

\[\left. 2+\cos\left(\frac{\pi t}{11}\right) \right|_{t=0}^{t=6}=~?\]

Answer 12

Hope that helps
