Answer:
It will take 13.5 minutes for the liquid to reach - 10.8°C.
Step-by-step explanation:
The initial temperature of the experiment is 0°C and as the experiment goes on, the temperature of the liquid is changing at a rate of - 0.8°C per minute.
So, the equation that models the situation is
T = 0 - 0.8t
⇒ T = - 0.8t ................. (1)
Where T is the temperature of the liquid in °C and t is the time of spending after the experiment starts in minutes.
Now, given T = - 10.8°C and we have to find the corresponding time (t) in minutes.
So, from equation (1) we get,
- 10.8 = - 0.8t
⇒ t = 13.5 minutes
Therefore, it will take 13.5 minutes for the liquid to reach - 10.8°C. (Answer)
When multiplying terms with the same base with exponents, you keep the base and add the exponents.
2^4 * 2^3 = 2^7
Any number with an exponent of zero equal one.
4^0 = 1
Multiply exponents when the term is being multiplied by a power.
(2^4)^3 = 2^12
When dividing terms with exponents, you keep the base and subtract the exponents.
9^7/9^5 = 9^2 9^5/9^7 = 1/9^2
