Answer:

Range: (-3,0,3,6,9)

Step-by-step explanation:

We need to evaluate each value in the domain of the function, so

f(-2)=3(-2)+3=-6+3=-3

f(-1)=3(-1)+3=-3+3=0

f(0)=3(0)+3=0+3=3

f(1)=3(1)+3=3+3=6

f(2)=3(2)+3=6+3=9

Why is any number to the zero power equal 1 example for kids?

professor190 [17]

Think of the power series ^2, ^3 etc as defining the characteristics of the line on a graph that the power function draws.

The awful reality is that the logical answer is buried in the axioms of set theory. So instead of having to teach kids axioms and derivations, just draw the lines on a graph as i described.

^0 = a line with zero slope, ^1 = a straight line with a slope of 1, ^2 = an exponential line... etc...

For kids, relating the power series to the shapes of lines on a graph will also help them later on when they learn about functions etc (like y = mx + c). Being able to associate the different powers with actual shapes on a graph will also help them to visualize relationships in physics, should they take that path. It's not the real truth, but a nice correlation with it's own merits.

1. Kim works as a book keeper and creates invoices for a variety of companies. Help Kim find the total

Zanzabum

This is about calculation of invoice.

1) Total for the invoice = $2641.25

2) Total for the invoice = $30

3) Total for the invoice = $1925

1) 12 cameras for $200 each

Amount for cameras = 12 × 200 = $2400

25 cables with length of 10 ft each cost $1.25

Amount for 10 ft cables = 25 × 1.25 = $31.25

12 ft specialty cables cost $1.75 per foot

10 of these cables will have length =12 × 10 = 120 ft

Amount for 10 of these cables = 1.75 × 120 = $210

Total for the Invoice = $2400 + $31.25 + $210

Total for the invoice = $2641.25

2) 250 yards of rope costs $500.

Thus, price per yard = 500/250 = $2 per yard

For a customer that wants 15 yard;

Total for the invoice = 15 × $2 = $30

3) Dump truck is rented for $275 per hour. And the minimum is 2 hours per day. This means that anything less than 1 hour, the money paid must be money for 2 hours.

Thus;

On monday; 1 hour will cost; 2 × $275 = $550

On Tuesday; 3 hours will cost; 3 × $275 = $825

On wednesday; 2hours will cost; 2 × $275 = $550

Total for the invoice = 550 + 825 + 550 = $1925

GalinKa [24]

Answer:

Sorry, If this late but here's the answer. The data plots represent the hours students study each week in two different classrooms. The mean number of hours a student in Mr. Hart’s class studies is 4.6 hours. The mean number of hours a student in Ms. Perry’s class studies is 2.8 hours. A typical student in Mr. Hart’s class studies More than a typical student in Ms. Perry’s class. Good Luck!
