3. Your desktop computer uses between 100 - 250 watts when in use (depending on

the components) and around 3 watts when turned off (on average). NIPSCO is

currently charging $0.1165 per kilowatt-hour. How much would you pay for

electricity each year even if you never turned your computer on? What if you had it

on 24 hours per day, every day? What if you turned it off every night, and only

turned it on every evening for a few hours?

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

current in the circuit at time t is /, then the power delivered to the resistor is

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
