Question

alones · Answer

i'm not sure tho but is is 5√ 5

shastri007 · Answer

Using Pyth Thrm, c^2 = a^2 + b^2
c^2 = (5)^2 + (10)^2
c^2 = 25 + 100
c = Squareroot of 125
Which 5 root 5
Indeed correct.! Good job

thanks! ;)

Let$$f(x)=-\frac{1}{2}x+5.$$Then$$f'(x)=-\frac12$$and$$\int_0^{10}\sqrt{1+\left(-\frac12\right)^2}\,dx=\left.\frac{\sqrt5}{2}x\right|_0^{10}=5\sqrt5.$$
