A rocket is shot off from a launcher. The accompanying table represents the height of the rocket at given times, where x is time, in seconds, and y is height, in feet.
a. Write a quadratic regression equation for this set of data, rounding all
coefficients to the nearest hundredth. y =___x^2+___x+_
b. Using this equation, find the height, to the nearest foot, at a time of 6.4 seconds_feet

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
