The table below shows temperatures of a mixture in a chemistry experiment over 5 days.
On which two days did the mixture’s temperature have the same absolute value?

Days
Monday
Tuesday
Wednesday
Thursday
Friday
Temperature (*C)
-7.1
-3.4
-1.2
2.1
3.4

Step-by-step explanation:

3.4 and -3.4 both have the same absolute value.

It appears that these days would be Tuesday and Friday based on the data you have provided.

Absolute Value

Absolute value is based on the numbers alone, and not the sign in front of them (negative or positive)

When considering absolute value, ignore positive and negative signs. Absolute value is indicated by terms inside of | | straight vertical lines

Example:

|3.4| = 3.4

|-3.4| = 3.4

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
