Is the area of a reg. decagon with a perimeter of 240, A=4431.86? PLEASE HELP ME-A decagon with a perimeter of 240 has a side of 24. The angle between two consecutive radii is 36°
a/sin(72°) = 12/sin

A company manufactures computer chips, and it is known that 3% of them are faulty. In a batch of 500 such chips, find the probability that between 1 and 2 percent (inclusive) of the chips are faulty.-
I got an easy A is calculus, but a hard to obtain B+ in precalc-Hey, BoxingTiger,
Im with you. When I first took calculus, I was blown away by the simplicity and elegance with which it allows us to s
Integral from D (2x+3y)dxdywith respect to D: limited line x+y>=-2,x-Probably the trickiest part with these equations is determining the limits of integration. The lines you describe give a triangular
Because its easier to state, and were going from a value of -1 to 1. the other would go from a value of 1 to -1-Sine function is a circular function.
Its ordinates always lie in the interval[-1,1]
Its
and what is the domain of y=ln(3-x)
please show your work
thanksss-Well, the domain of (x + 3) / (x^2 + 9) would be all the values for which the expression is defined. The way I wrote it, the domain
through the points P(1, 2, 1) & Q(2, 1, 4), and is parallel to the x-axis.
I managed to get the right answer using the unit vector for the x-axis [1, 0, 0], the vector PQ and one of those two points,
1.Find the equation of the circle whose center and radius are given.
center ( -2, -5), radius = 1
and
2.Find the equation of the circle whose center and radius are given.
center ( 5, 6), radius =
When we are studyinga function and trying to figure how it looks like we usually study the sign of this function, putting f(x) > 0.And then we will have a region of the graph where its positive and re
I cant remember how to do this so,
The US population is 311,430,000; I have to find out how many of them is 76 percent.
I have no idea how to do this. Its my key component in my essay. Please help.
that has the same x & z intercepts as the plane with equation 2x + 5y - z + 7 = 0.In vector form.
One of the points is (0, 0, 7), another is (-7/2, 0, 0), and using those I can get the vector [7/2, 0
if they give us 2 points:
A( 5,-12) b(2,-1)
how do u graph it!???
i know u find the slpe. but what about the y intercept ?? how do u find that??
TANX-lets first review the slope-intercept form:
y
I know how to do the whole numbers such as 9^3/2...........but I cant figure out how to do one with a fraction, like this....(1/4)^3/2
I know the answer, I could use help with the steps please-For (1
