Iwant to paint all three walls of the kitchen. one wall is half a cylinder. i want to paint the walls only, not the ceiling. the walls are 9' high. how many square feet will i be painting? round to the nearest tenth.

335.5 sq ft.

Step-by-step explanation:

Let's start with the 2 straight 10-feet long walls, it's easier.

Each of those two wall sections are 10 feet long by 9 feet high...  They're rectangles, so their area is their base (10) by their height (9).

Wall 1 = 10 x 9 = 90 sq ft

Wall 2 = 10 x 9 = 90 sq ft

Now the half-circle portion.

The trick here is to calculate half of the circumference. The circumference of a circle is given by C = 2 π r, but we only want half of it... so C/2 = π r

We have the radius (r = 5.5 ft).

So, the half circle has a (half) perimeter of: 5.5 π r = 17.28 ft

Then we multiply this by the height of 9 feet: 17.28 = 155.52 sq ft

Then we add the two other walls:

Total area = 90 + 90 + 155.52 = 335.52, which we round down to 335.5 sq ft.

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
