Answer:
3.06 megawatts
Step-by-step explanation:
Firstly, we write the proportionality equation.
wind power varies directly as the square of the length r of one of the blades;
P ∝ r^2
Let’s introduce a constant of proportionality k; This means;
P = kr^2
Now let’s calculate the value of k when 1.5 megawatts and r is 35m
1.5 mw = 35^2 * k
k = 1.5/35^2 = 1.5/1225 = 0.001224489796 MW/m^2
Now we want to calculate the amount of megawatts to be produced by a turbine with 50m blades.
That would be;
P = 0.001224489796 * 50^2 = 3.06 megawatts
Answer:
A =16.25 cm^2
Step-by-step explanation:
The area of a triangle is given by 1/2 bh where b is the base and h is the height
A = 1/2 (5) * 6.5
A =16.25 cm^2

Step-by-step explanation:
Answer:
x=-4.67
Step-by-step explanation:
add like terms 3-17
then take x=2x-14
add 2x to both sides
3x=-14
divide by 3 and you get your answer
