Answer:
0 ≤ t ≤ 5.
Step-by-step explanation:
In the function , is the independent variable. The domain of is the set of all values of that this function can accept.
In this case, is defined in a real-life context. Hence, consider the real-life constraints on the two variables. Both time and volume should be non-negative. In other words,
- .
- .
The first condition is an inequality about , which is indeed the independent variable.
However, the second condition is about , the dependent variable of this function. It has to be rewritten as a condition about .
.
Hence, t ≤ 5.
Combine the two inequalities to obtain the domain:
0 ≤ t ≤ 5.
6 1/4. So essentially, 6hrs and 15mins.
Answer:
36
Step-by-step explanation:
Answer:
21 for the first one, 144 for the second
Step-by-step explanation:
If you're seeing the same problem I am in class, the rule is: <em>N + 9</em>
N is equal to 12 in this equation
<em>12 + 9 is 21.</em>
So, the answer is 21
If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-
Is <em>12(12)= </em>144
Hope this helps!
(By the way, I'm horrible at math so this could be completely wrong)
