Mice21 [21]

For this case, we must find the quotient of

(15x ^ 3 + 12x ^ 2-9x) divided by3x, to verify if Tina was correct.

So:

\frac {15x ^ 3 + 12x ^ 2-9x} {3x} =\\\frac {15x ^ 3} {3x} + \frac {12x ^ 2} {3x} - \frac {9x} {3x} =\\5x ^ 2 + 4x-3

So, Tina was wrong, she had to divide by 3x.

In this circle, the area of sector COD is 50.24 square units. The radius of the circle is units , and units.
maks197457 [2]

Let angle be alpha

\\ \rm\Rrightarrow Area=50.24

\\ \rm\Rrightarrow \dfrac{\alpha}{360}\pi r^2=50.24

\\ \rm\Rrightarrow \alpha 3.14r^2=18086.4

\\ \rm\Rrightarrow \alpha r^2=5760

\\ \rm\Rrightarrow r^2=\dfrac{5760}{\alpha}

\\ \rm\Rrightarrow r=\sqrt{\dfrac{5760}{\alpha}}

If you have angle measure in degree put in place of Alpha and get the value elaw this is our final answer
