Please help I don't understand. The height of a penny dropped from a 64-foot tall bridge is modeled by the function

h = -16t² + 64, where t is the time in seconds and h is the height of the penny above the lake.

What is the height if the time is 2 seconds?

Is this function linear or nonlinear?

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) part b: which function has a greater y-intercept? justify your answer. (4 points)

What is the point slope form of a line with slope -5 that contains point (2,-1)

Measure a and b and find their sum. how are the angles related?
