- Pediatric growth charts suggest a linear relationship between age (in years) and median height (in inches) for children between 2 and 12 years of age. Two year olds have a median height of 35 inches and 12 year olds have a median height of 60inches. Generate an equation to describe height as a of age. A) H(a)= -2.5a + 30 B) H(a)= 2.5a + 35 C) H(a)= 2.5a - 30 D) H(a)= .4a - 12 E) H(a)= 2.5a + 30arrow_forwardUse a graphing calculator to find the approximate point of intersection of the pair of equations 2.5x +3.6y = 12.3 , y=1.2 In(x-2.24) round to thousandth placearrow_forwardMichael threw a ball into the air from the top of a building. The height of the ball, in feet, is modeled by the equation h = -16t2 + 64t + 60, where t is the elapsed time, in seconds. Graph this equation on the set of axes below. h 1501 140- 130 120- 110- 100- 90- 80- 70- 60- 50- 40- 30- 20- 10- 1 2 3 4 Time (in seconds) Determine the average rate of change, in feet per second, from when Michael released the ball to when the ball reached its maximum height.
