Arlecino [84]4 years ago
4 0

Answer:

$34,800

Step-by-step explanation:

5% of 8000 is 400

(1% is 80, 80 x 5 = 400)

8000+400=8400.

32000 - 8000 = 24000

10% of 24000 is 2400

2400 + 24000 = 26400

26400 + 8400 = 34800

Part 2: Use the information provided to write the standard form equation of each circle
Archy [21]

Answer:

The answer to your question is below

Step-by-step explanation:

- The Standard form of the equation is

                  (x - h)² + (y - k)² = r²

4.

Center (8, -4)    r = \sqrt{118}

-Substitution

                 (x - 8)² + (y + 4)² =\sqrt{118}²                

-Result

                 (x - 8)² + (y + 4)² = 118

5.

Center (-10, 9)     r = \sqrt{37}

-Substitution

                  (x + 10)² + (y - 9)² = \sqrt{37}²                

-Result

                  (x + 10)² + (y - 9)² = 37

6.-

Center (-8, 0)       r = 6

-Substitution

                  (x + 8)² + (y - 0)² = (6)²

-Result

                  (x + 8)² + (y - 0)² = 36

An 80-watt coffee maker is used an average of 0.5 hours a day. Find the cost of using the coffee maker for two weeks at a cost o
slavikrds [6]
80 W divided by 1000 (to convert to kW) = 0.08 kW
The total cost can be calculated by multiplying wattage by time by electricity cost. Note how the units will cancel out, given that 2 weeks is equal to 14 days.
(0.08 kW)(0.5 h/day)(14 days) = 0.56 kWh
Multiply by the cost: ($0.08/kWh)(0.56 kWh) = $0.0448

So the closest answer is the first choice.

Three vertices of a parallelogram are shown in the figure below. Give the coordinates of the fourth vertex.
Radda [10]

Answer:

(1,-8)

Step-by-step explanation:

We were given three vertices of a parallelogram to be:

(3,-2), (-1,-4), (5,-6).

After plotting the points as shown in the attachment, we realize (3,-2) and (-1,-4) form a diagonal.

The midpoint of this diagonal using the midpoint formula is  

is  

Recall that, the midpoint of both diagonals are the same.

Let the fourth point have coordinates (x,y).

Then using the midpoint formula again with (3,-2), we have:

This implies that:

and  

and  

x=1 and y=-8

The coordinates of the fourth point are:

(1,-8)
