A.) The average rate of change is $0.50, meaning that for each minute of talk time, the monthly bill increases by $0.50.
B.) The average rate of change is $0.50, meaning that for every ten minutes of talk time, the bill increases by $0.50.
C.) The average rate of change is $0.05, meaning that for each minute of talk time, the monthly bill increases by $0.05.
D.) The average rate of change is $0.05, meaning that for every ten minutes of talk time, the bill increases by $0.05.
For this case, the first thing we must do is find the average rate of change for the mentioned interval.
By definition we have to:
Substituting values we have:
Rewriting we have:
Answer:
C.) The average rate of change is $0.05, meaning that for each minute of talk time, the monthly bill increases by $0.05.

Answer:
Option 3 -
Step-by-step explanation:
Given : Options in the figure.
To find : Which of the following is a complex number?
Solution :
Complex number is defined as the number which contains real number along with imaginary number.
The complex number is in the form of a+ib.
Now, we determine one by one.
Option 1 - -7
-7 is the real number not complex.
Option 2 -
is the real number not complex.
Option 3 -
is in the form a+ib so it is a complex number.
Option 4 -
is the real number not complex.
Therefore, Only option 3 is the complex number.
65% of the floor space is covered, how many square feet are NOT covered?
Answer:
47,250 ft^2
Step-by-step explanation:
Area: 450 * 300 = 135,000 ft^2
65% of 135,000 =
135,000 * 0.65 = 87,750 ft^2 (space covered)
135,000 - 87,750 = 47,250
Answer:
A=30,32,44,48
B=22,34
intersect=26
numbers going outside is 24,28,36,38,40,42,46
b) 1/14
Step-by-step explanation:
a)The numbers that will go into the A bracket will be 30,32,44 and 48. The numbers that will go into the B bracket will be 22 and 34. The number that will go into the intersect will only be 26. And finally the numbers going on the outside of the venn diagram will be 24,28,36,38,40,42,46.
b)The answer will be 1/14
