Answer: = 62.8 pounds of CO₂

Step-by-step explanation:

1 kilowatt per hour produces 0.99 pounds of C02.

The total wattage in hours used was;

= 7,043 * 9 hours

= ‭63,387‬ watts

In kilowatts;

= ‭63,387‬/1000

= 63.387 kilowatts

CO2 produced;

= 63.387 * 0.99

= ‭62.75313‬

= 62.8 pounds of CO2

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (2, 5)

Point (-3, 7)

Step 2: Identify

x₁ = 2, y₁ = 5

x₂ = -3, y₂ = 7

Step 3: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{7-5}{-3-2}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{2}{-5}$
[Slope] [Fraction] Rewrite: $\displaystyle m=\frac{-2}{5}$

Given the two vertices and the centroids of a triangle, how many possible locations are there for the third vertex?

hoa [83]

Answer:

Step-by-step explanation:
