If an arrow is shot upward on mars with a speed of 54 m/s, its height in meters t seconds later is given by y = 54t − 1.86t^2. (round your answers to two decimal places.) (a) find the average speed over the given time intervals. (b) estimate the speed when t = 1.

step-by-step explanation:

the

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
