In one day a movie store rented out 32 comedies. If the ratio of comedies to action movies rented was 8:7, how many action movie

Shalnov [3]

$\bf \cfrac{comedie}{action}\qquad 8:7\qquad \cfrac{8}{7}\qquad \qquad \cfrac{32}{a}=\cfrac{8}{7}\implies \cfrac{32\cdot 7}{8}=\stackrel{action}{a}$

Write 0.4 as a fraction.

ICE Princess25 [194]

I don't see the answer choice here that 0.4 should be ,which is 4/10,once reduced by dividing both 4 and 10 by 2 ,you would get an answer of 2/5???Are you sure these choices are correct?

The region in the first quadrant bounded by the x-axis, the line x = In(pi), and the curve y = sin(ex) is rotated about the x-ax

Basile [38]

Answer:

Step-by-step explanation:

Please refer to the graph below.

So, we want to find the volume of the solid generated by revolving the green area about the x-axis.

We can use the disk method. The disk method is given by:

$\displaystyle V=\pi\int_a^bR(x)^2\, dx$

Where R(x) is the radius or height of the representative rectangle.

We are integrating from x = 0 to x = ln(π). The height of a representative rectangle is given by y. Therefore, the volume is:

$\displaystyle V=\pi\int_0^{\ln(\pi)}(\sin(e^x))^2\, dx$

Simplify:

$\displaystyle V=\pi\int_0^{\ln(\pi)}\sin^2(e^x)\, dx$

Approximate. So, the volume of the generated solid is:

$V\approx 2.498\text{ units}^3$

The solid is shown in the second figure.
