Aball is thrown into the air with an initial velocity of 22 meters per second. the quadratic function h(t)=-4.9t2+22t+5.5represents the height of the ball above the ground, in meters, with respect to time t, in seconds.

A ball is thrown into the air with an initial velocity of 22 meters per second.

The quadratic function h(t) = -4.9t2 + 22t + 5.5 represents the height of

the ball above the ground, in meters, with respect to time t, in seconds.

Determine h(3) and explain what it represents.

h(3) = 27.4

h(3) = 27.4 means that the ball throw into the air with an initial velocity of 22 meters per second is 27.4 meters above the ground after 3 seconds.

The quadratic equation that represents the height of the ball above the ground, h(t), in meters, with respect to time, t, in seconds is given by:

To find h(3), substitute t = 3 into given quadratic equation and solve for it

Plug in t = 3 in h(t)

Thus h(3) = 27.4

h(3) = 27.4 means that the ball throw into the air with an initial velocity of 22 meters per second is 27.4 meters above the ground after 3 seconds.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,
