Multiply and simplify

That would be the cube root of (x+5)^11.

If desired, this could be reduced to the cube root of (x+5)^9*(x+5)^2, which would be

(x+5)^3*(x+5)^(2/3)

Find f'(x) for f(x) = cos^2(3x^3).

garik1379 [7]

$f(x) = \cos^2(3x^3)\\f'(x) = \frac{d}{dx}[\cos^2(3x^3)]\\= 2\cos(3x^3) \cdot \frac{d}{dx}[cos(3x^3)]\\= 2\cos(3x^3) \cdot (-\sin(3x^3)) \cdot \frac{d}{dx}[3x^3]\\= 2\cos(3x^3) \cdot (-\sin(3x^3)) \cdot 9x^2\\= -18x^2\cos(3x^3)\sin(3x^3)$

The opening soccer game at the new arena was attended by approximately 2,800 Caucasians, 4,800 African Americans, and 15,00 Hisp

worty [1.4K]

<u>Answer:</u>

The ratio of African Americans to Hispanics Americans present is 16 : 5

<u>Explanation:</u>

Given the people attending the soccer game were:

2800 among them are Caucasians

4800 are African Americans

1500 are Hispanics

And, 1400 of those were from other ethnic backgrounds

We have to find the Ratio of African Americans to Hispanics Americans

Therefore,

African Americans : Hispanics Americans = 4800 : 1500

$\frac{\text { African American }}{\text { Hispanics American }}=\frac{4800}{1500}=\frac{48}{15}=\frac{16}{5}$

Hence, the ratio of African Americans to Hispanics Americans present in the ratio were 16 : 5

The combined ages of megan and kyle are 27. if kyle is twice as old as megan, how old is kyle.

Natali [406]

kyle is 18 and megan is 9, because 9 + 18 = 27 and 27 / 3 = 9. hope this helps :)
