Instantaneous

If you are given y = -2x^2 + 3 Find the instantaneous at x= 1/2 if you know... Secant Line 1 Passes through [1/2f(x)] and [1f(1)] Secant Line 2 Passes through [1/2f(x)] and [2f(2)] Secant Line 3 Passes through [1/2f(x)] and [3f(3)]

A train travelling at a constant speed of 100 km/h travels west for 45 minutes, northwest for 30 minutes and finally north for 15 minutes. What is the trains average velocity for the trip?

Explain how you can tell whether a polynomial equation is a function and not just a relation.

I was wondering if you could help me solve this projectile motion problem. A projectile is launched with an initial speed of 14.5 m/s at an angle of 35° above the horizontal. The object lands at the same height from which it was launched. Air resistance i...

A red and blue six-sided die are rolled. What is the probability that the red die shows a face greater than the blue die?

Solve for n given: nP2 = 110

Vi = 0 m/s Vf = 28 m/s Δt = 4s Average Acceleration = Vf - Vi / Δt = 7 m/s^2 d=vi*t + 1/2*a*t^2 = 1/2(7*16) = 56m

D=VT T = D/V T = 1.65m/152 m/s T = 0.0109 s

Option D makes more sense.

For each value of the independent there is either none or one value for the dependent right? Meaning that x cannot have 2 y values and then its a function. (Passes VLT)

Nevermind, I solved the problem.
