Using function concepts, it is found that the domain is 0 ≤ t ≤ 2.4, given by option C.
----------------------
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.

Answer:
140
Step-by-step explanation:
- 143,622 bacteria present on day 15
- the bacteria doubles twice a day
that means each day backwards, the bacteria is four times less the day before
therefore:
- on day 14, the number of bacteria is 143,622 / 4
which is 35,905.5
and so on!
so:
- day 13 = 8,976.375
- day 12 = 2,244.09375
- day 11 = 561.0234375
- day 10 = 140.255859375
this rounded to the nearest whole number is
= 140 bacteria
(you can't have a part of a bacteria!)
hope this helps! :)
if it is solution point (4, –2) must satisfy both equations
(1) –3x – 2y = –8-->-3*4-2*(-2)=-8
-12+4=-8 then-->-8=-8 ok
(2) y = 2x – 5
-2=2*4-5=3---------->-2 is not 3
the point (4, –2) is not solution of the system of equations
It’s the circle. Obviously
