The height of the apple after t seconds is given by:

- The domain of a function is the <u>set that contains all possible input values.</u>
- The possible input values for this situation are the values of t between 0 and the instant in which the apple hits the ground, which is t for which
.
----------------------

Which is a quadratic equation with 
To find the solutions:



The apple is in the air for 0 ≤ t ≤ 2.4, which means that the domain is given by option C.

Just substitute the first equation into the second and solve for x: <span><span>32</span>x=−<span>12</span>x+4⟹2x=4⟹x=2</span><span>Now, since y = 3/2 * x, we have y = 3 and we are done.</span>
Answer:
option 4 and 6
Step-by-step explanation:
Answer:
15 percent of 90 hours = 13.5 hours
What is 15% of 90?
Y is 15% of 90
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 15% * 90
Converting percent to decimal:
p = 15%/100 = 0.15
Y = 0.15 * 90
Y = 13.5
