PLEASE HELP!! I have asked this many times with no answers I really need help. 1. What is the direction, y-intercept, and zeroes of f(x) = 4x^2 + 10x + 12.

2. Find the vertex and the equation for the axis of symmetry of the parabola, showing your work

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
