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 =
-Substitution
(x - 8)² + (y + 4)² =
²
-Result
(x - 8)² + (y + 4)² = 118
5.
Center (-10, 9) r = 
-Substitution
(x + 10)² + (y - 9)² =
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
The answer is
A. 1
B. 25
C. 10
D. -2
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.
Answer:
153.2 gallons per day
Step-by-step explanation:
To find out how much water he used each day, take the amount of water he used and divide by the number of days
1072.4 gallons / 7 days
153.2 gallons per day
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)
