Answer:
6.2 seconds
Step-by-step explanation:
To translate into math, the question is asking you "for what approximate t value does h = 0?" In order to solve, you can plug in 0 for h and solve for t.
0 = -16t^2 + 620
-620 = -16t^2
620 = 16t^2
38.75 = t^2
= t
6.2 ~~ t (rounding to the nearest tenth)
Don't forget your units!

The value of the temperature in function notation is gotten as; f(x) = 91 - 11x
<h3>How to write a function Notation?</h3>
Let us first find the relationship between temperature and how long the turkey sits out.
The temperature after the normal 390 minutes is equal to approximately 6.5 hours.
Let us create a ratio and solve for x, which represents the temperature change during that extra hour after the "normal time sitting out".
Thus;
(7.5/6.5) = (80/80+ x)
Solving for x gives x = -10.7.
This means that for every extra hour it sits out, the turkey cools approximately 11°. When we add that to 80°, we have 91° which is the expected temperature after 390 minutes (6.5 hours) of sitting out.
Thus, the motion as a function of time is;
f(x) = 91 - 11x

Im gonna guess 6.00 beacause it says round to hundreths
