I received a problem in class that Im having trouble solving. The problem is: There are twelve students in the student government (seven seniors and five juniors) who are conducting an election for f

How do you do this problem

(1/4x^2) - (x+1/x^2) = (1/2x^2) I am just really confused in how to do this problem.-1/(4x^2) - (x+1)/x^2 = 1/(2x^2) lowest common denominator is 4x^2: 1/4x^2 - 4(x+1)/4x^2 = 1(2)/4x^2 NOW drop

Can you answer these 6 math questions? please. I will give 10pts

1. Identify the vertex. tell minimum or maximum. y=-3x^2 2.y=5x^2+1 3.order from widest to narrowest graph. y=x^2,y=5x^2,y=3x^2 4.y=-8x^2,y=1/2x^2,y=-x^2 5. graph each function. just say coordinat

Formulae help with homework pleasee????!!!!!

guys i am stressed out and i dont know how to do this this is the question, how do we do it ---> Given the formula v=u + at, find the value of v if u=3, a=2 t=4-v = 3 + ( 2 x 4 ) v = 3 + 8 v = 11-Than

How to get the integral of f(x) when only given graph of f '(x)

also they give that f(x) is an even function and f (-3)=f (3)=0... and then they say that f(0)=0, and to find the integral of f(x) from -a to a. but i dont see how any of this info helps in finding th

Please check my answer!!!!

Consider the vectors and find the number using dot product. a = {-2,-2} b = {-3, 3} c = {5, -1} (a-b) . (b +c) = i got -10 but my online homework system says its wrong i reworked it numerous times and

-3x^2+12=0 BEST ANSWER. What did i miss

-3(x^2-4)=0 -3(x+4)(x-1)=0 x+4=0 , x-1= 0 x=-4 x=1-4,1 So why is this wrong? I think I followed every step. Can someone tell me what i missed?-Hi! Okay, so, when you took the x-squared minus 4 part a

Help how would I solve this equation: z^4 = 4z^2 + 32

z^4 = 4z^2 + 32; subtract 4z^2 from both sides z^4 - 4z^2 = 4z^2 - 4z^2 + 32; simplify z^4 - 4z^2 = 32; subtract 32 from both sides z^4 - 4z^2 - 32 = 32 - 32; simplify z^4 - 4z^2 - 32 = 0; factor (z^2

Please help me solve this math problem

Half-live of lead is 22 years. How long will it takes for a sample of this substance to decay to 80% of it original amount? A = A0e^kt the answer is 7.1 years-A = A0e^kt Ln(A)= Ln(A0)+kt Ln(A)- Ln(A

Help with geometry?? Volume, surface area?? 2 questions!

Integral of sinx+sinx tan^2x/sec^2x

Your integrand is not at all clear. As typed (perhaps there are missing parentheses) your function is sin(x) + sin(x)tan²(x)/sec²(x) = sin(x) + sin(x)tan²(x)cos²(x) = sin(x) + sin^3(x). The anti-d
