Answer:
only -2 is in the domain
Step-by-step explanation:
For negative values under the sqrt, there is no real answer, hence
-2x ≥ 0
only for x=-2 this is the case.
The domain represents all the valid input values for x.
a. Sean drank at a rate of 5 milliliters per second.
b. It took Sean 55 s to drink all the slushy.
<h3>a. How to find the rate at which Sean drank?</h3>
Since Sean darnak at a constant rate and originally there were 275 milliliters of slushy in the cup. After 13 seconds, 210 milliliters of slushy remained.
The rate at which Sean drank, r = Change in volume of slushy/time for change
= (275 mL - 210 mL)/13 s
= 65 mL/13 s
= 5 mL/s
So, Sean drank at a rate of 5 milliliters per second.
<h3>b. How long did it take Sean to drink all the slushy?</h3>
The time it takes Sean to drink all the slushy is given by
T = V/r where
- V = total volume of slushy = 275 milliliters and
- r = rate of drinking by Sean = 5 mL/s
So, T = V/r
= 275 mL/5 mL/s
= 55 s
So, it took Sean 55 s to drink all the slushy.
