Some fireworks are fired vertically into the air from the ground at an initial speed of 80 feet for second. The equation for this object’s height h at time t seconds after launch is h = -16t^2 + 80t. How long will it take the fireworks to reach the ground ?

Rose drew a regression line for this paired data set. her line passed through (1, 2) and (3, 5) . what is the equation of rose's regression line?

Will mark brainliest with 20 points! the table shows how far object 1 traveled as a function of time. *time (seconds) - 2 4 6 8 *distance traveled (feet) - 18 36 54 72 the equation shows how far object 2 traveled in feet as a function of time in minutes. *f(x) = 10x which object traveled at a faster speed? justify your response.
