If an arrow is shot upward on mars with a speed of 58 m/s, its height in meters t seconds later is given by y = 58t − 1.86t2. (round your answers to two decimal places.) (a) find the average speed over the given time intervals.

answer:

your answer is: c. 196 7/8 in^3.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
