How can I perform an action within a `for` loop every 5 results? Basically I'm just trying to emulate a table with 5 columns.

An object moves in a straight line with acceleration a(t) = t^2 ft/s^2. If the initial velocity of the object is −9 ft/sec, at what time t does the particle change direction?

1.  (ab -2) (ab +2) = ab^2 + 4   (is this correct)   2.  Can 8a^3 -27 be factored?  I cannot find a way to do it   3.  Can x(x -2)(x +3) = 0 be solved?  I did x=2 and y = -3 and nothing fits to... more

Which of the following gives the length of the path described by the parametric equations x=(1/4)t^4 and y=t^3, where 0≤t≤2?   a) ∫ t^6+9t^4 dt from 0 to 2   b) ∫ sqrt(t^6+1) dt from 0 to... more

The length of a curve from x=0 to x=1 is given by ∫ sqrt(1+16x^6) dx from 0 to 1. If the curve contains the point (1, 4), which of the following could be an equation for this curve?    a)... more

Can someone, anyone answer this asap please it is for my homework and I don't know how to do this and I will be having a test on it.

prove that  1 - Cos^2x = Cos^2x Tan^2x

Find lim as (x, y)--->(0, 0) for (8x^2*y^2)/(x^4+y^4). lim as (0, y)--->(0, 0) =0/y^4=0 lim as (x, 0)--->(0, 0) =0/x^4=0 The limit is 0, right? But doesn't exist is the answer for this... more

Factor each polynomail completely. If it cannot be factored say it is prime.
