The function f(t) =16t 2 + 248 models the height f(t) in feet of a stone t seconds after it is dropped from the edge of a vertic
Hatshy [7]

Answer:

The time it takes for the stone to reach the ground is 3.94 s. This answer is correct.

Step-by-step explanation:

I believe there's a mistake in the equation shown, the acceleration (number that multiplies t²) should be negative, since the stone is falling, therefore I'll answer assuming it's -16 instead of 16, otherwise there would be no real solution to the equation.

In order to calculate how long it'll take for the stone to hit the ground we must make f(t) = 0 and find the time "t" that makes the equation valid, so we have:

f(t) = -16t² + 248 = 0

-16t² = -248

t² = -248/(-16) = 15.5

t = sqrt(15.5) = 3.94

Need to find A and B, I already found C
Semenov [28]
I'm going to assume you've learn sin, cos, and tan. To find a you must do:
sin^{ - 1}  =  \frac{a}{12}
Once you find a, you can use the Pythagorean Theorem to find b:
{a}^{2}  +  {b}^{2}  =  {c}^{2}
Or you can do:
cos^{ - 1}  =  \frac{b}{12}
You can find these functions on a scientific calculator. Let me now if you need more help.
