<span>Let's solve your equation step-by-step.
-x^2 = -36
</span><span>Step 1: Divide both sides by -1.
</span><span>-x^2/-1 = -36/-1
x^2 = 36
</span><span>Step 2: Take square root.
</span>x=<span>±<span>√<span>36
</span></span></span><span>x=<span><span>6 or </span>x</span></span>=<span>−<span>6
</span></span><span>
Answer: </span><span>x=<span><span>6<span> or </span></span>x</span></span>=<span>−<span>6

Answer:
Answer is below
Step-by-step explanation:
The vertical asymptote is x = 1. The horizontal asymptote is y = 2.
I graphed the function on the graph below.
A 120 watt light bulb uses about 0.1 kilowatt of electricity per hour.if electricity costs $0.20 per kilowatt hour.
Let's solve how much does it cost to have a bulb on
for an hour.
=> 120 watt = 0.1 kilowatt per hour which costs 0.20 per kilowatt per
=> 0.1 kilowatt per hour * 0.20 = 0.02 dollars in an hour.
