What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given that Eric works in a restaurant. Sometimes he clears tables.

The scatter plot shows how much he earned in tips by clearing tables on different days.

From the scatter plot, number of tables are represented on the x axis.

Tips earned in dollars are represented on y axis.

Eric will earn about $10 for clearing 6 tables is not true because eric earns $11 dollars for cleaning 6 tables.

Eric will earn about $16 for clearing 11 tables is true from scatter plot.

Hence, option D is correct, Eric will earn about $16 for clearing 11 tables.

A repairperson buys a new heavy-duty electric drill with installment payments. The initial cost of the drill is $300. The repairperson makes six payments. The total payments for the drill add up to $324. How much interest does the repairperson pay?

Answers

The repair person paid an amount of interest of $24.

What is Subtraction?

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference.

Given that,

A repairperson buys a new heavy-duty electric drill with installment payments.

Initial cost of the drill = $300

Number of installment payments made = 6

Total payment for the drill = $324

Amount of interest = Total payment for the drill - Initial cost of the drill

                               = $324 - $300

                               = $24

Hence the interest paid is $24.

The total number of burgers sold from a restaurant from Monday to Sunday can be modeled by the function f(d)=200d3+542d2+179d+1605and the number of visitors to the restaurant from Monday to Sunday can be modeled by g(d)=100d+321, where d is the number of days since Monday. What is the average number of burgers per person?

Answers

Answer:

2d^2-d+5

Step-by-step explanation:

The total number of burgers sold from a restaurant from Monday to Sunday:

f(d)=200d^3+542d^2+179d+1605

The number of visitors to the restaurant from Monday to Sunday:

g(d)=100d+321

To find the average number of burgers per person, just divide f(d) by g(d).

First, multiply g(d) by 2d^2 and subtract the result from f(d):

200d^3+542d^2+179d+1605-2d^2(100d+321)\n \n=200d^3+542d^2+179d+1605-200d^3-642d^2\n \n=-100d^2+179d+1605

Then, multiply  g(d) by -d and subtract the result from -100d^2+179d+1605:

-100d^2+179d+1605-(-d)(100d+321)\n \n=-100d^2+179d+1605+100d^2+321d\n \n=500d+1605

Now, multiply  g(d) by 5 and subtract the result from 500d+1605:

500d+1605-5(100d+321)\n \n=500d+1605-500d-1605\n \n=0

Hence,

f(d)=g(d)(2d^2-d+5)

and the function

b(d)=2d^2-d+5

represents the average number of burgers per person.
