Find f if f ''(x) = 12x2 + 6x − 4, f(0) = 5, and f(1) = 4.
Taya2010 [7]
This is a differential equations problem.  We are to work backwards and determine the function f(x) when given f "(x) and initial values.

<span>f ''(x) = 12x^2 + 6x − 4, when integrated with respect to x, yields:

                x^3        x^2
f '(x) = 12------ + 6----- - 4x + C, or 4x^3 + 3x^2 - 4x + C, and
                  3            2

             x^4         x^3        x^2
f(x) = 4------- + 3------- - 4------ + Cx + D, or f(x)=x^4 + x^3 - 2x^2 + Cx + D
               4              3         2

Now, because f(0)=5, 5=0^4 + 0^3 -2(0)^2 + C(0) + D, so that D=5.
Determine D in the same manner:  Let x=1 and find the value of C.

Then the solution, f(x), is x^4 + x^3 - 2x^2 + Cx + 5.  Replace C with this value and then you'll have the desired function f(x).</span>

Assoli18 [71]

Answer:

42.7 m

Step-by-step explanation:

The Circumference of a circle is found by multiplying the radius of the circle by 2π.  Here the radius is 6.8 m.  The circumference of this circle is

C = 2π(6.8 m) = 13.6π m, or (to 1 decimal place, 42.7 m.

Your information isn't complete. Therefore, an overview of the fraction will given.

Let's assume that Lisa ran 1/2 of a mile and Jane ran 3/4 of a mile. In order to know who ran more, you can convert the fraction to percentage.

This will be:

Lisa = 1/2 × 100 = 50%

Jane = 3/4 × 100 = 75%

Therefore, Jane ran more.
