While gaming, a Playstation 4 uses about 140 Watts of energy. A flat-screen TV uses about 150 Watts. If you are gaming for 4 hours a day 5 times a week for a year, how much will that cost you if you pay 5 cents/kWh? Your answer should have $/kWh as the unit. *

Step-by-step explanation:

The problem statement tells you the cost of energy is $0.05/kWh. If those are the units required for the answer, that is the answer.

__

The question, "how much will that cost you?" suggests the units of the answer should be dollars (not dollars per kWh). In that case, we need to know the number of kWh used during the year. The total annual cost will be ...

  (0.14 kW +0.15 kW)(4 h/day)(5 day/wk)(52 wk/yr)(1 yr)($0.05/kWh)

  = (0.29)(4)(5)(52)($.05) = $15.08

Your cost will be $15.08 for the electricity for a year.

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
