F(-1) = -11
f(0) = -9
f(3) = -3
Answer:
B. 
Step-by-step explanation:
<em><u>To find the perimeter, use the formula:</u></em>
P = a + b + c
P = 12 + 12 + 9.7
P = 33.7
<em><u>To find area, use the formula:</u></em>
A = 
A = 
A = 
A = 54
Here are some factors of 20!
1x20=20
2x10=20
4x5=20
5x4=20
Therefore there are 4 factors of 20.
Regular polygon can be incribed in a circle of radius equal to its side.
so if you join all the vertices to the centre, you will get 6 equilateral triangles. each interior angle will have 2 angles of 60 each. thus interior angle = 120
exterior angle=180-120=60
The length of the diagonal of the rectangle will be 14.142 units.
<h3>What exactly is a rectangle?</h3>
It has four sides and is a polygon. The internal angle total is 360 degrees. The opposing sides of a rectangle are parallel and equal, and each angle is 90 degrees.
Rectangle diagonals are equally equal and meet at the midpoint.
O is the circle's center, MNOP is its rectangle, and the circle's area is 100 in the diagram to the left.
Area of circle=πr²
100 π= πr²
r= 10 units
The length of the rectangle is equal to the radius of the circle is 10 units. The length of the diagonal is √2 times the side of the rectangle;
L=√2 R
L=1.414×10
L=14.14
Hence the length of the diagonal of the rectangle will be 14.142 units.
