Break this problem down first. You have two lines each with length of 5. You also have two halves of a circle, combine them to get a full circle with a radius of 2. The formula to find the perimeter of a circle is
and this gives a perimeter of 12.566 for the circle. Add this to your sides and you get a total of 22.566 which is answer B
Answer:
y - 2 = -(x + 4)
Step-by-step explanation:
A max at (-4, 2) could very well be the vertex (as well as the max) of a parabola that opens down. The vertex form of a parabola is:
y - k = a(x - h), where (h, k) is the vertex or maximum.
Given that our max is at (-4, 2), write: y - 2 = -(x + 4), with that " - " sign stemming from the fact that the parabola opens down.
50 meters
Explanation
you can easily solve this by using a rule of three.
Step 1
Let
x represents the length of the actual lawn
then
the proportion is the same, so
Step 2
so, the length is 50 meters
