The International Space Agency has landed a robotic explorer on a planet. The robot launches a baseball directly upward at 147 ft/s. The equation for the path of the baseball is: h = -149t^2 +...

I don't know how to do this problem

I don't normally ask for this extent of help. but can someone walk me through the last bit of this equation. I know the steps, but I keep getting it wrong, my teachers out of town, and I don't have...

I've been working on this problem for a while now and I just can't figure out where i'm going wrong. Find the quadratic function y+ ax^2p+ bx+ c whose graph passes through...

Aon object is launched at 17.2 m/s from a 25-meter tall platform. The equation for the object's height h at time t seconds after launch is: h(t) = -4.9t^2 + 17.2t +25, where h is...

Find the gradients of the lines with y intercept 1 that are tangents to the curve y=3x^2+5x+4

Find the values of m for which the lines y=mx-2 are tangents to the curve with equation y=x^2-4x+2

Step by step problem solution

My answer booklet says the answer is 4/2 (or 1/2), but I don't understand why it's not 4/1. Thank you in advance!
