Suppose that the distance d feet that a car travels in t seconds is given by d(t)=2t^2. calculate the average speed (average rate of change.) in feet per second from t=5 to t=9. (an exact number.)

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a

step-by-step explanation:

mark brainliest!

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
