Answer:
<u>The correct answer is 58.82 square meters of solar panels will be needed to supply 2 kilowatts</u>
Step-by-step explanation:
Solar cell energy supply = 34 watts per square meter
Therefore, 100 square meters will supply 3400 watts which is 3.4 kilowatts.
How many square meters of solar panels would you need to 2 kilowatts?
Total energy = 2 kilowatts = 2,000 watts
Number of square meters = Total energy/Solar cell energy supply
Number of square meters = 2,000/34
<u>Number of square meters = 58.82</u>
<u>It will be necessary 38.82 square meters of solar panels to supply 2 kilowatts</u>
(x-h)^2=4p(y-k)
vertex is (h,k)
p is the distance from focus to vertex and distance from vertex to directix (vertex is in middle of directix and focus)
if p is positive, the parabola opens up and the focus is above the directix
if p is negative, the parabola opens down and the focus is below the directix
we see the directix is over the focus (1>-1) so the parabola opens down and p is negative
distance from (5,-1) to y=1 is 2 units
2/2=1
p=-1 since p is negative
1 up from (5,-1) is (5,0)
veretx is (5,0)
(x-5)^2=4(-1)(y-0)
(x-5)^2=-4y is the equation
