You are jumping on a trampoline. For one jump, your height y (in feet) above the trampoline after t seconds can be represented by y= -16t^2+24t. How many seconds are you in the air?

.

Step-by-step explanation:

The person in this question is in the air whenever the height is greater than .

The graph of is a parabola opening downwards. Rearrange and find values of that would set this expression to .

.

The first factor, , suggests that would set this expression to - quite expected, since the person is on the ground right before jumping.

The second factor, , suggests that (in other words, ) would also set this expression to . Hence, this person would be once again on the ground seconds after jumping.

Hence, this person is in the air between and for a total of .

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
