The temperature of a liquid in an experiment starts a 0 degrees celsius. the experiment calls for the temperature of liquid to change at a rate of -0.8 degrees celsius per minute. how long will it take for the liquid to reach -10.8 degrees celsius? estimate to show that your answer is reasonable.

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)

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
