Margo missed 24.6% of the free throw shots in a season During the season she took a total of 90 free throw shots. Which, of the

adoni [48]

Answer:

C. 22

Step-by-step explanation:

The problem statement tells you ...

missed = 24.6% × 90

= 0.246 × 90 = 22.14

The best estimate among the answers given is 22, choice C.

_____

Comment on the problem statement

The percentage given is supposedly computed from the number of shots attempted and missed this season. The ratio 22/90 would give a percentage rounded to 24.4%, not 24.6%.

24.4% of 90 is 21.96, closer to 22.

Use the shell method to find the volume of the solid generated by revolving the regions bounded by the curves and lines about th

RSB [31]

Answer:

The volume of the solid is:

$\displaystyle\frac{19\pi}{6}$

Step-by-step explanation:

See the graph of the region attached.

To find the intersection between the line and the parabola we set the equation equal to each other, and solve that quadratic equation by factorization:

$x^2=9-8x\\x^2+8x-9=0\\(x+9)(x-1)=0\\x=-9,x=1$

Since the region is the one for $x\ge 0$ then the intersection we are interested on is x=1 as it can also be seen in the graph.

Then we set the integral using shell method for revolving about the y-axis:

$\displaystyle\int_a^b 2\pi\,x\,h(x)\,dx$

Where h(x) is the height of the shell which here is the distance between the parabola and the line, so $8x-9-x^2$ (since the line is on the top we subtract from it the parabola)
