Let the trajectory of the ball be represented by $f(x) = -0.05\cdot (x-16)^{2}+11$ , where $x$ is the horizontal distance of the ball from origin, in feet, and $f(x)$ is the height of the ball above ground, in feet.

If Deshawn does not block Chris's shot, then we should check if shot will be a goal and this condition must be fulfilled:

$f(25\,ft) < 8\,ft$ (1)

If we know that $x = 25\,ft$ , then the height of the ball at the start of the goal is:

$f(x) = -0.05\cdot (x-16)^{2}+11$ (2)

$f(x) = 6.95\,ft$

Since $f(25\,ft) < 8\,ft$ , then we conclude that it will be a goal.

Answer:

The first one is 15.75 lbs or 15 3/4. The second one is 28 years old. The third one is$9.90 each t-shirt

Step-by-step explanation:

For the first one you multiply 18 by 14 and you get 252. Then there is 16 ounces in a pound so you divide by 16. Then you get 15.75. So that is your answer. The 2nd one you take 84 and multiply it by 1/6 then since she is twice the age of her sister you multiply by 2. so it would look like: 84 times 1/6= 14

14 times 2 = 28. So she is 28 years old. The third one you take 32 and subtract it by 12.20. You will be left with 19.8. Then both t-shirts cost the same so you would divide 19.8 by 2. You are left with 9.9. So the answer is $9.90. Sorry this took 10 minutes.
