Determine the name of the following triangle using the given points: A(5,6), B(-1,-2) and C(-3,2). Be as specific as possible. I used the distance formula and found that AB had a side of 10 BC had a side of 2 sqrt 5 CA had a side of 4 Sqrt 5 I found that...

Determine the domain of the following function: f(x)=sqrt x-7/x^2-5x-6 I think the domain is [7,all real numbers) Can you please tell me if this is correct?

An open box is formed by cutting squares out of a piece of cardboard that is 22 ft by 27 ft and folding up the flaps. What size corner squares should be cut to yield a box that has a volume of less than 235 cubic feet? I know that the size corner squares...

A pizzeria sells a rectangular 18 X 24 inch pizza for the same price that it sells its large 24" diameter pizza. If both pizzas have the same thickness, which option gives the most pizza for the money. Gosh I'm really rusty on my geometry. Can you give me...

Determine the solution. x^2=|x|algebraically I have no idea how to proceed with this. Can you please help?

Determine the center and the radius of the following circle: x^2+y^2+6x-4y-5=0 I got for the radius 3(sqrt2) I got for the center (-3,2) Can you please tell me if I am correct? The radius seems wierd.

Use the following conditions to create a sketch of the function by hand. a. f(x) is increasing from (-infinity,-4)union(-4, infinity) b. there is a vertical asymptote at x=-4 c. There is a horizontal asymptote at y=2 d. f(0)=-5; f(1)=-3; f(3)=1 I have an...

Here I am again stuck with another geometry type question. Here goes: A rectangle is inscribed between the x-axis and the parabola y=36-x^2 with one side along the x-axis. He drew the picture with the parabola at points (-6,0) (6,0) (0,6) the rectanle is...

I already asked this question and had some help, but I am still confused on a piece of it. I'm not sure what differentiate is. I understand how you got a and b, but I am confused with c. What is differentiate and how did you get the equation dA/dx = 72 -...

Can you simplify radical 253?

A pool, that is 12 feet wide and 18 feet long, is to have a sidewalk of uniform length constructed around its perimeter. a. write the equation for the area A, of the pool with the sidewalk b. determine the domain of the area of the pool with the sidewalk...

Find the dimensions of the rectangle with minimum perimeter if its area is 400 square meters. Find the least perimeter. I know that a rectangle has two sides that are equal and two other sides that are equal but I am unsure about what type of equation to...

Hornworts differ from mosses and liverworts in containing: a. small leaves b. photosynthetic sporophytes c. gametphytes d. sporophytes e. spores Well, First I thought ok its small leaves and that was wrong. Next I thought it would be spores and that was w...

Thanks so much for your explanation. I was able to figure it out and now got your answer.

Ok, so you're using the pathagorean theorum. I'm a bit rusty on my geometry so does that make it a right scalene?

:) Thanks!

I used the same equation you said then put it in the graphing calculator and found the intersection points. I'm thinking that you would put [.42,9.46) to show that it is more than .42 and less than 9.46.

Thanks so much. Any ideas on my other question?

Ok, so I got x=0 x=1 x=0 x=-1 is that right?

Thank you for your guidance! Have a great night.

I understand how you got a and b, but I am confused with c. What is differentiate and how did you get the equation dA/dx = 72 - 6x^2

f(x)=7x-4 So, you substitute: a. 7(0)-4=-4 b. 7(-3)-4=-25 can you take it from here?

OOPS, I meant Pre-Calc not ap Calc sorry

Ok, well now I'm really confused. I thought about substituting 400/x into y but I still don't have anything to put it equal to. Can you please try to explain it.

When I graphed it, I got a reciprocal function not a parabola. I don't know how to find a minumum that's not a parabola or a cubic. Should I just go with the guess and check and call it 20 X 20?
