400

Explanation:

1/3 of 600 is 200. That represents the boys.

Subtract 200 from 600, you get 400. That represents everybody else in the sample size (in this case, girls).

Find the definite integral from 0 to 1/16 of arcsin(8x)/sqrt(1-64x^2)dx

kolezko [41]

$\displaystyle\int_0^{1/16}\frac{\arcsin8x}{\sqrt{1-64x^2}}\,\mathrm dx$

First let $y=8x$ , so that $\mathrm dx=\dfrac{\mathrm dy}8$ to write the integral as

$\displaystyle\frac18\int_0^{1/2}\frac{\arcsin y}{\sqrt{1-y^2}}\,\mathrm dy$

Now recall that $(\arcsin y)'=\dfrac1{\sqrt{1-y^2}}$ , so substituting $z=\arcsin y$ should do the trick. The integral then becomes

$\displaystyle\frac18\int_0^{\pi/6}z\,\mathrm dz=\frac1{16}z^2\bigg|_{z=0}^{z=\pi/6}=\frac{\pi^2}{576}$

A store owner received 18 cases of soda. Each case has 24 cans of soda. The owner sells each can for $0.60. Which number sentenc

Radda [10]

Answer:

Total money get from soda cans = $259.2

Step-by-step explanation:

Given:

Number of soda cases = 18

Number of soda can in each case = 24

Price of each soda can = $0.60

Find:

Total money get from soda cans

Computation:

Total money get from soda cans = Number of soda cases x Number of soda can in each case x Price of each soda can

Total money get from soda cans = 18 x 24 x 0.60

Total money get from soda cans = $259.2

Write sin(19°) in terms of cosine.

Leto [7]

Answer:

cos(71)

Step-by-step explanation:

Since 19° is less than 90, we can express this in terms of confunction.

sin(θ) = cos(90-θ)

sin(19) = cos(90-19)

sin(19) = cos(71)
