Answer:

4 seconds

Step-by-step explanation:

On the ground, height = 0

-12x(x - 4) = 0

x = 0, 4

It was on the ground initially at x = 0, and again at x = 4

Which of the following equations is of a parabola with a vertex at (1,2)
labwork [276]

ANSWER

The choice is correct.

y = {(x -1)}^{2}  + 2

EXPLANATION

The equation of a parabola in vertex form is given by:

y = a {(x -h)}^{2}  + k

where (h,k) is vertex of the parabola and 'a' is the leading coefficient of the parabola.

From the given options, the leading coefficient must be a=1.

We also have the vertex of the parabola at (1,2). This implies that h=1 and k=2.

We substitute these values into the formula to get,

y = {(x -1)}^{2}  + 2

The second option is correct.

sara nick and robin were collecting cans for a recycling project . sara collected 5 times as many cans as robin . nick collected
artcher [175]
R = robins cans
s = sara's cans
n = nick's cans
T = total cans

s = 5r
n = 6r
T = 216 = s + r + n

we sub in the first two equations into the first

216 = 5r + 6r + r
216 = 12r
r = 18
sub this back into equations 1 and 2

thus

r = 18
s = 90
n = 108
