each sail on the windmill is 5 meters in length How much area do the sails cover as they turn from the force of the wind

1 answer:

When the windmill turns, its sails will form a circle of 5m radius.

So area = pi*radius^2

= 3.14*5^2

= 3.14*25

= 78.5 sq.m

Write the equation of the line with a slope of -5 and y-intercept of 12.

Wittaler [7]

Answer:

y=-5x+12

Step-by-step explanation:

Since slope-intercept form is y=mx+b, m is the slope, and b is the y-intercept. We substitute m for -5, since it is the slope, and we substitute 12 for b, since it is the y-intercept. I hope this helps!
