1.1666666666667 times 500 = 583.333333333333 seconds

The formula for the volume of w sphere is v=4\3 r3 what is the formula solved for r?

Lyrx [107]

V of w sphere = $\frac{4}{3}$ $\pi$ r³
Multiply by 3 on either sides to get rid of the fraction.
$V * 3 = \frac{4}{3} *3 \pi r^3$
3V = 4 $\pi$ r³
Now divide either sides by 4 $\pi$ to isolate r³
$\frac{3V}{4 \pi } = \frac{4 \pi }{4 \pi }$ r³
4 $\pi$ and 4 $\pi$ cancels out
$\frac{3V}{4 \pi }$ = r³
Take the cube root to isolate r.
$\sqrt[3]{ \frac{3V}{4 \pi } } = \sqrt[3]{r^3}$
the cube root cancels the cube

$\sqrt[3]{ \frac{3V}{4 \pi } }$ = r

25/2 * 12/5 =

150/5 =

30 miles per gallon

Miranda's car :

(20 5/7) / (5/7) =

(145/7) / (5/7) =

145/7 * 7/5 =

145/5 =

29 miles per gallon

Given the parabola whose equation is , find the focus and determine if the parabola opens up or down.

ziro4ka [17]

The equation of a parabola is:
$y = ax {}^{2} + bx + c$
If a>0, then the parabola opens up;
If a<0, then the parabola opens down.
The coordinates of focus are:
$( - \frac{b}{2a} \: \: \frac{1 - b {}^{2} + 4ac}{4a} )$
