need help on a few math problems 1) (y2)^-4- y8 2) (4y^4)^3/2 3)2n/4n^1/2-I assume that you mean: Problem 1) .. ( y^(2) )^(-4) - y^(8) = y^( 2 * (-4) ) - y^(8) = y^(-8) - y^(8) = 1/y^(8) - y^(8) = (

Help me with this math question..

I have this triange with the following meseaurments: In triangle ABC: angle A is : 37.5, side b is: 5.6, side c is :15.2 and side a is : 11.2 also angle C is: 124.9 How would this triangle look li

For a, b belong to R\{0} define a ~b if and only if a/b belong to Q

a) prove that ~ is an equivalence relation. b) find the equivalence class of 1. Can anybody help me on this. thanks in advance-a) For a,b,c in R \ {0}: Reflexive: a ~ a, because a/a = 1, which is in

1/2 a = 3/4 b (Algebra homework.)

1) 1/2 a = 3/4 b 2) y= 3( 5-2x) 3) 3a/2 + 2(b+3a)/3 = -1 4) S= 2n - 4 5) 5(3 - 2d) = 6(f + 4)-What is your Algebra hw asking you to do? Edit: OK, lets do a couple: 1) 1/2 * a = 3/4 * b a = 3b/4 / 1/

If h(x) = f(x) g(x), and it is known that f(3) = -4, f'(3) = 5, g(3) = 1, g'(3) = 2. Then h'(3) =

h(x) = f(x) g(x) h(x) = f(x) g(x) + f(x) g(x) h(3) = f(3) g(3) + f(3) g(3) = (-4)(2) + (5)(1) = -8 + 5 = -3

How do you integrate : taninverse(2x) / (1+4x²)

∫ arctan(2x)/(1 + 4x²) dx Let u = arctan(2x).Then, du/dx = 2/(1 + (2x)²) [Note that d/dx arctan(f(x)) = f(x)/(1 + f(x)²)] du/dx = 2/(1 + 4x²) du = 2/(1 + 4x²) dx du/2 = dx/(1 + 4x²) [Rearrange the t

Subtract imaginary numbers

subtract (-7-2i) - (-4-2i) Type answer in form of a + bi-(-7 - 2i) - (-4 - 2i) = -3 + 0i That can just be written as -3, too. Cheers!-Just treat i as any other variable: (-7 - 2i) - (-4 - 2i) -7 -
