Answer:

How long is the [shirt] in the air? 3 seconds

How many seconds after launching is the t-shirt at 17 feet? 0.25 seconds

Step-by-step explanation:

Formula to represent the shirt's flight path (given): h=-16t^2+vt+c, where h is the height of the shirt, v is the initial velocity of the shirt, c is the shirt's starting height, and t is elapsed time since launch.

The function forms a parabola concave down. Since the shirt is caught at 17 feet, we want to second x-coordinate of a point with a y-coordinate of 17 that the function passes through. This is because the shirt was caught going down, not up.

Therefore, let h=17:

17=-16t^2+52t+5,\\\\-16t^2+52t-12=0,\\\\ y= \frac{-52\pm\sqrt{52^2-4(-16)(-12)}}{2(-16)},\\\\y=\frac{1}{4},\boxed{y=3}.

The second x-coordinate is the larger of the two and therefore the shirt was in the air for 3 seconds.

However, the first time the shirt reaches a height of 17 feet is on its way up, which occurs at 1/4 or 0.25 seconds (the first x-coordinate). Therefore, the t-shirt reached a height of 17 feet 0.25 seconds after launching.

When you flip a biased coin, the probability of getting a tail is 0.31. Find the probability of getting a head
Genrish500 [490]
Well if the probability of getting a tail is 0.31 then the probability of getting a head must be 0.69 because 0.31 is much like 31% and the last 0.69 makes 69% resulting in the total 100% chance when combining the outcome chances seeing as a coin only has 2 sides. (Assuming we are speaking of an U.S. coin here) <span />

slamgirl [31]
A decagon is a polygon which has ten sides. A regular decagon is characterized by equal side lengths. An important dimension of this polygon is the side length. The area is expressed as:
A=(5/2)a^2(√5+(2√5))
A = <span>(5/2)16^2(√5+(2√5))</span>A = 1969.72
