Find a sine function with these properties

amplitude 8 period 5 phase shift +pi is the answer f(x) = 8sin(2pi/5(x-pi)) and f(x) = -8sin(2pi/5(x-pi)) or just the first one? If its only the first one why so?-f(x) = 8sin(2pi/5(x-pi)) is the ans

I already compute the integral of the function and I got 1.1 but it is wrong!

compute integral of the following function when upper bound is 6 and lower bound is 4 f(x)=(5(x^2)+1)/(x^2)-(5x^2 + 1) / x^2 => (5x^2 / x^2) + 1 / x^2 => 5 + x^(-2) Integrate: 5x - x^(-1) From 4 to

X-intercept of y= 5x^2-2x +4

help? and explain please! thanks-no x-intercept vertex x = 5/2 , y = (5/2)^2-5(5/2)+16 = ...-oh god.....my brain hurts. maybe google it, look for some math help. google is better than yahoo.

How do you solve 81+2k=5k

subtract 2k from both sides so you have 81=3k then divide both sides by 3 so you get 27=k :D-Subract 2k from both sides. This gives you: 81=3k Then divide both sides by 3. This gives you: 27=k Ho
