X equals 62 because you take 147 and subtract it from 180 and that gives you 33.
then you add 33 and 85 together to give you 118. Then you subtract 118 from 180 and that gives you 62.

Find f such that f'(x) = 5x² + 9x - 7 and f(0) = 8.

faltersainse [42]

Answer:

$\frac{5}{3}x^3+\frac{9}{2}x^2-7x+8\\$

Step-by-step explanation:

Integrate your function with respect to x to get the non-differentiated form.

$\int(5x^2+9x-7)dx=\frac{5}{3}x^3+\frac{9}{2}x^2-7x+c\\$

Plug in your known value of x to get your value for your constant

$f(0) = 8\\ \frac{5}{3}(0^3)+\frac{9}{2}(0^2)-7(0)+c = 8 \\c=8$

This gives you your function to be

$\frac{5}{3}x^3+\frac{9}{2}x^2-7x+8\\$

Christine runs 7 miles in 60 minutes. at the same rate, how many miles would she run in 24 minutes?

Mashcka [7]

Let x = the unknown amount of miles she would run. We are going to set up a proportion.

$\frac{7 miles}{60 min} = \frac{x miles}{24 min}$

Now we are going to cross-multiply and solve for x.

60x = 7(24)
60x = 168
x = 168 / 60
x = 2.8

Christine runs 2.8 miles in 24 minutes.
