That would be 0.75:) hope this helps!
Area covered by the solar cells = 269.5 m^2
Area of one cell = 150 cm^2
Convert the area of one cell to m^2 by using the conversion factor 1m^2 = (100cm)^2 => 1 = 1m^2 / 1000 cm^2
=> 150 cm^2 * [1m^2 / 1000 cm^2] = 0.150 m^2
Now finf the number of times that 0.150 is contained in 269.5 by dividing 269.5 by 0.150
269.5 = 0.150 = 1,796.67
Which means that the number of cells is betwee 1796 and 1797.
Tanα=5/12
α=arctan(5/12)°
α≈22.62° (to nearest hundredth of a degree)
20x^4-39x^3-16x
Make sure to multiply all the terms by each other in the two parentheses
