Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
0=2x²−10x+7
Step 1: Subtract 2x^2-10x+7 from both sides.
0−(2x²−10x+7)=2x²−10x+7−(2x²−10x+7)
−2x²+10x−7=0
For this equation: a=-2, b=10, c=-7
−2x²+10x+−7=0
Step 2: Use quadratic formula with a=-2, b=10, c=-7.
Answer:
<h2>$ 0.06 per kWh</h2>Step-by-step explanation:
Capital costs of the Solar Energy Project is expected at $ 995,000.
Average yearly operating costs are $ 175,000. The project is estimated to run for 25 years, producing a total 89,500,000 kWh.
LCOE = Levelized Cost of Energy =
LCOE =
∴ Levelized Cost of Energy = $ 0.06 per kWh
Answer:
Approximately, there is a distance of 25,6 foot between the base of the flagpole to the house.
Step-by-step explanation:
We are given the following in the question:
Height of pole = 20 foot
Angle between pole and ground = 85 degrees
Angle of elevation from the base of the house to the top of the pole = 55 degrees
Then, the third angle of the triangle can be found as:
Angle sum property of triangle: The sum of the three angles of a triangle is 180 degrees.
Thus, by the sin rule, we can write:
Approximately, there is a distance of 25,6 foot between the base of the flagpole to the house.
