If f'(x)= and f(1)=5, then f(3)=
(a)1.230
(b)3.585
(c)6.230
(d)8.535
(e)11.230

E

Step-by-step explanation:

Since the given expression is an elliptic integral, it's not easy to find F(x) explicitly. However, if we use a linear approximation, we can try to estimate F(3), though it won't be too close, since 3 is not very close to 1.

At the point (1,5) the slope of the tangent line is F'(1) =

So, using that line,

F(3) = F(1) + F'(1)(3-1) = 5+2 = 7.828

Well, that didn't work out too well.

So, let's pull out our handy integral calculator, and we find that

But, we know that F(1) = 5. So we need to add C = 3.889

Now, integrating again,

Oops. I messed up the limits, but you get the idea.

50x5=$250

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
