I would say Powerpoint, Openoffices, and some other softwares just type in " Keynote " and download if you have a Mac. Also try Google Docs Presentation. And Sliderocket ( you can also add pics with it! ) Try 280 Slides or Prezi!
for 4 some one already gave you so you have: 4a: 1/sqrt(5) 4b 2/5 4c 1/2 4d 0
1/sqrt(2) -1/sqrt(2) 1/sqrt(2) 1/sqrt(2)
0.5, 0, 0, 0.5, 0, 0.5, 0.5, 0
0.5, 0, 0, 0.5, 0, 0.5, 0.5, 0
0.0887 is the answer....correct on and say thanks.....

Lacey was right!(:
3 is A 5 is C 9 is A 10 is B 11 is C Those are right because I did this test already. :) The ones I didn't mention already have the right answer.
I dunno, but maybe u can help me!

it is based off the equation: displacement = (initial velocity)*(change in time) + 1/2(acceleration)*(change in time squared) since that equation is linear, the equation recommended for this problem is: "angle" = 0 + 1/2(acceleration)*(change in time squared) that is...
Say, cost per day = D Say, cost per km = k 3D + 150k = 180 2D + 400k = 180 Multiply the first equation by 2 and the second by 3: 6D + 300k = 360 6D + 1200k = 540 Subtract the first equation from the second: 900k = 180 Divide both sides by 900: k = 0.2 2D + 400k = 180 2D + 400(...
There are no like terms. It cannot be simplified.
Say Aarons age = 2A years Therefore, Half of Aarons age = A years Therefore, Tanya's age = A+10 2A + A+10 = 55 3A + 10 = 55 3A + 10 -10 = 55 - 10 3A = 45 A = 15. Therefore, Tanya is 15 + 10 = 25 years old. (Aaron is 2 x 15 = 30 years old)

Your question, I assume, is to find the length and width of the rectangle? The diagonal creates 2 right triangles. L = length L - 4 = width By the Pythagorean theorem, d^2 = L^2 + (L - 4)^2 20^2 = L^2 + (L - 4)^2 Solve for L, the length width = L - 4

If this is your equation, M = −0.001t^3 + 0.1t^2 t = 14 min Substitute 14 for t and solve M = −0.001t^3 + 0.1t^2 M = −0.001(14)^3 + 0.1(14)^2 Now solve for M = number of words in 14 min
This assumes that sides PQ and ST are corresponding sides. You do not state the relation of the sides in your problem. Create a proportion matching the corresponding sides and perimeters. PQ/ST = Perimeter PQR/Perimeter STU 18/6 = 78/x 18x = 468 x = 26 = Perimeter STU
Multiply the area of the rectangle by the square of the scale factor to get the area of reduced rectangle. Reduced area = 720 * (1/6)^2 Reduced area = 720 * (1/36) Reduced area = 720/6 Reduced area = ? sq in.

Miss Sue, I think you missed the "0" before 45 (0.045 not 0.45) 0.045 = 45/1000 = 9/200 = 0.045 So, the fraction is, 45/1000 = 9/200 (reduced to lowest terms) 0.045 * 100 = 4.5% So, the percent is, 4.5%
Are 22, 16, and 28 the sides of this triangle? What is "a nine in the middle" mean? What does this "9" represent? Your question cannot be answered as worded. What exactly does your problem say or state to do?
You need to use parenthesis. If this is your problem v/(v+5)+v/3 = -4/(v+5) Multiply both sides by 3(v+5) 3v + v(v + 5) = -12 3v + v^2 + 5v = 12 v^2 + 8v + 12 = 0 (v + 2)(v + 6) v = -6 or v = -2 Make sure you check the solutions in the original equation. I have NOT checked the...

I think I read the question wrong. I thought the question wanted the slope of the tangent of f(x) at (1,-5) and the two equations at this point.

You need parenthesis. I'll assume your problem is, x/(x+1) + 5/x = 1/(x^2 + x) x/(x+1) + 5/x = 1/(x(x + 1)) Multiply both sides by x(x + 1) x^2 + 5(x + 1) = 1 x^2 + 5x + 5 = 1 x^2 + 5x + 4 = 0 (x + 1)(x + 4) = 0 x = -1 or x = -4 Make sure you check both answers in the orig...

If this is what you mean, cube root = cr (cr(81)) = (cr(27))*(cr(3)) (cr(81)) = 3*(cr(3)) (cr(81)) = 3(cr(3)) This can be written as 81^(1/3) = 3(3^(1/3)) 81^(1/3) = (3^(3/3)*(3^(1/3)) 81^(1/3) = 3^(4/3)
