Jake tosses a coin up in the air and lets it fall on the ground. the equation that
models the height (in feet) and time in seconds) of the parabola is
- -16t2 + 24 + 6. when does the coin reach its greatest height?

The coin will reach the maximum height of 15 feet in second

Step-by-step explanation:

The equation that models the height (in feet) and time in seconds) of the parabola is

The coin will reach its greatest height at the parabola's vertex. Find the coordinates of the vertex.

From the function expression:

Now,

Then

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.
