Answer:
Average temperature = 9°F per minute
Step-by-step explanation:
Given : the temperature of a pot of water fell from 72°F to 36°F in 4 minutes.
To find : Find the average temperature per minute.
Solution : We have given
Temperature decreases in 4 minute = 72°F to 36°F
72 -36 = 36°F
Temperature decreases in 4 minute = 36°F
Temperature decreases in 1 minute = .
Temperature decreases in 1 minute = 9°F
Average temperature = .
Average temperature = 9°F per minute.
Therefore, Average temperature = 9°F per minute.

Answer:
Step-by-step explanation:
From the graph, the x-intercepts are;
These are root of the polynomial function represented by the given graph.
By the remainder theorem;
According to the factor theorem, if is a factor of
, then
This implies that;
are factors of the required function.
Hence;
We expand using difference of two squares to obtain;
We expand using the distributive property to get;
Rewrite in standard form to obtain;
Rationalizing the denominator, simply means "getting rid of that pesky root at the bottom", and we do so by simply multiplying it by something to take it out, of course, we multiply the bottom, we have to also multiply the top,
