A flying disk is thrown into the air from a height of 25 feet at a time T=0. The function that models this situation is h(t) = 16t 2 squared + 75 t + 25, where T is measured in seconds and H is height in feet. What values of T best describe the times when the disc is flying in the air?

Incorrect question, the correct Question is h(t) = -16t 2 squared + 75 t + 25

Therefore,

t = 5 seconds suits the best value.Step-by-step explanation:

Given:

The function that models flying disk situation is

Where  is measured in seconds and h is height in feet.

To Find:

What values of T best describe the times when the disc is flying in the air?

t = ? at h(t) = 0

Solution:

The function that models flying disk situation is

Put h(t) = 0

As t cannot be negative

t = 5 s

Therefore,

t = 5 seconds suits the best value.

false

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
