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)
The polynomial function f(x) with roots 4 – 13i and 5 have factor of x - (4 - 13)
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Polynomial function f(x) has roots 4 – 13i and 5. Hence:
x = 4 - 13i; and x = 5
x - (4 - 13) = 0; and x - 5 = 0
f(x) = [x - (4 - 13)](x - 5)
The polynomial function f(x) with roots 4 – 13i and 5 have factor of x - (4 - 13)
