Answer:

A = 19.6

Step-by-step explanation:

A = C² / 4π

C² = 246.49

4π = 12.56

246.49 / 12.56 = 19.625

Rounded to the nearest tenth = 19.6

An Air Conditioner uses 850 Watts of electricity and local emissions from electricity produce 1.37 pounds of CO2 per kWh. If you
Zina [86]

Answer: 6,987,000 pounds fo CO₂ per kWh.

Step-by-step explanation: <u>Quilowatt</u>-<u>hour</u> <u>(kWh)</u> is a unit of energy that measures the amount of energy expended in 1 hour.

The AC uses 850 Watts, which in kW is 850,000 kW

If you leave the AC on for 6 hours, it will consume

850,000(6) = 5,100,000 kWh

Eletricity produces 1.37 pounds of CO₂ per kWh, then in 5,100,000 kWh:

1.37 \frac{pounds}{kWh}.(5,100,000kWh) = 6,987,000 pounds

If you open a window for 6 hours, you would keep 6,987,000 pounds of CO₂ for entering the atmosphere.

What is the perimiter of ABC with vertices A (-2,9), B(7-3), and c(-2,-3) in the coordinate plane?
Serggg [28]

Answer:

|AB| = √((7 - (-2))^2 + (-3 - 9)^2) = 15

|BC| = √((-2 - 7)^2 + (-3 - (-3))^2) = 9

|AC| = √((-2 - (-2))^2 + (-3 - 9)^2) = 12

Perimeter = 15 + 9 + 12 = 36

Can anybody help me with the explanation
Delvig [45]

Answer:

see explanation

Step-by-step explanation:

f(3) means the y-coordinate of the point (3, y) that lies on f(x).

Aha! Now we have a path to the solution!

We can test random values for y, such as (3, 1), (3, 2), or even (3, 1000).

This leads us to drawing lines.

Answer: We draw the line x=3(equivalent of testing out random points), and where it intersects the graph of f(x)! is our answer!

(Note: it can only intersect once, otherwise it would fail the vertical line test and wouldn't be a function)
