Mason throws a ball straight up into the air with an initial velocity of 12m/s2 12 m / s 2 . If the point at which Mason released the ball from his hand was 1.25 meters above the ground is modeled by the equation h(t) = −4.9t2+12t+1.25 h ( t ) = - 4 . 9 t 2 + 12 t + 1 . 25 , how long will the ball be in the air for rounded to the nearest tenth?

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

6e14 is the answer.

the answer is b.
