A lunette is a semi-circle, which means that it is one half of a circle. To find its area, we can find the area of the whole circle and divide it by two.

Area of a circle: A = pi x r^2

r = 40 / 2 = 20

A = pi x 20^2

A = 400pi / 2 = 200pi

200pi = 628.32

The area of the lunette is approximately 628 in^2.

Hope this helps!! :)

Which statements prove that a quadrilateral is a parallelogram?
Ad libitum [116K]

Answer:

1st and 2nd statements are true.

Step-by-step explanation:  

We are asked to choose the correct statements that can prove that quadrilateral DEFG is a parallelogram.  

We will use parallelogram properties to answer this problem.    

Since we know that a parallelogram has two sets of opposite angles congruent, therefore, 1st option is a correct choice.    

Since a parallelogram has one set of opposite sides that are both congruent and parallel, therefore, second statement is true.  

Since the consecutive angles of a parallelogram are supplementary, therefore, 3rd statement is not true.  

Since the diagonals of parallelogram bisect each other, therefore, 4th statement is not true.

What is an equation of the line that passes through the points (-1, -6) and (6, 1)?
Agata [3.3K]

Answer:

Step-by-step explanation:

It is vital  to first find the gradient/ slope between the points

m=\frac{y2-y1}{x2-x1} \\=\frac{1-(-6)}{6-(-1})\\ \\m=1

let us use the point (6,1) to find the value of c

y=mx+c

1=1(6)+c

1-6=c

∴c=-5

the equation is given by

y=x-5

G(x)=3x-5 find g(-2)
lesya692 [45]

Answer:

g(2) = -11

Step-by-step explanation:

So, g(-2), basically meaning that x = -2.

Since we know that, we need to plug -2 into all of the x's.

g(2) = 3(-2) - 5

g(2) = -6 - 5

g(2) = -11
