I've tried to do it by using the points 0,0,0 and two other points contained in the line and creating a matrix. However, whenever i try to calculate it, I end up recieving a singular matrix error in my calculator. The points arnt collinear, why is this?

i just dont understand these problems:

1. region bounded by graph of f(x)=cosx and the x-axis, x E [-pi/2, pi/2], is revolved about the x-axis. find the volume of the resulting solid.

2. region bounded by the y-axis and the graphs of y=sinx and y=cosx, 0
TIA

Say a car dealership sells one type of car. The car has three options, of which a buyer can get any combination (none, one, two, or all three). The car also comes in four colors.

If the dealership sold 100,000 of these cars, what is the MAXIMUM number of any one type of car (meaning a distinct set of options/color) that you can GUARANTEE were sold.

At first I thought this was easy, then I thought about it and am unsure of how to solve it.

I am trying to evaluate the Bromwich integral which computes the inverse Laplace transform of a given function. The integral is as follows:

/c+i*infinity
|
I F(s)*exp(s*t) dt
|
/ c-i*infinity

where F(s)= s^p/(s^2+1)^q
p and q are positive, c is greater than the real part of all the singularities of F(s), and i^2=-1.

So the integration is done along the vertical line x=c in the complex plane.

I appreciate all answers or hints. If you can't work with F(s), substitute values for p and q and work with that.

at the end of my H.S math class today our teacher asked the class if they could solve this problem. (this is not my homework)

you have 4 numbers: 7, 7, 3, 3. What can you do with these numbers to get 24 and you cant use exponents. And trust me there is an answer.

equation:
(2/3) (1-2x) - (3/2x) + (5/6x) "greater than or equal to" (2x-1) / (3) + 1

would i have to distribute the 2/3 first and mulitply by 3 then solve?
would the interval notation be (-infinity, -1/3] ?
thanks for the help.

suppose that a square picture frame has sides that vary between 9.9 in and 10.1 in. what range of values is possible for the perimeter P of the picture frame? and how do i express this using a three-part inequality?

i know the perimeter is 39.6 for the 9.9" and 40.4 in for the 10.1". do i need to calcute the 40 in perimeter for sides of 10"?
thanks for the help.

I find advanced trigonometry [*extremely*] easy and I find advanced algebra [*extremely*] easy and I find *all* 'high level' mathematics easy [*extremely*]. Now, 'simple' addition and subtraction, now that I find hard.

Please please just tell me I'm normal.

I spose I'm not; I'll just have to help society another way. Say something nice.

I am doing my homework but this one problem I've done 3 times always comes out wrong.

3x-5y+z=8
4y-z=10
7x+y=4

I get y= -11.4
x=2.2
z=55.6

I know I'am doing it wrong but what am I doing wrong?
