Your original answer was correct...
Both polygons have five sides, and five sided polygons are called pentagons.
20 feet because 5.5 times 2 is 11 and 4.5 times 2 is 9 so 11 plus 9 is 20. Hope this helps!
By using studying graph of function, the correct option is the fourth option
What is a function
A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.
There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.
Here,
For x
1, (Solid dot is given, so equality is maintained here),
At x = 1, y = -1.
This happens for the function y = -2x + 1
So for x
1, the function is y = -2x + 1
Now for x < 1, (Hollow dot is given, so the equality will not be maintained here ),
At x = 1, y = 1
This happens for y = -x + 2
So for x < 1, the function is y = -x + 2
So the function is
y = -2x + 1, x
1,
y = -x + 2, x < 1
Fourth option is correct

Answer:
B
Step-by-step explanation:
√((-20)²+21²)=√(400+441)=√841=29
cos θ=-20/29
sec θ=-29/20
Rearranging the equation shows that <span>a=9.5</span><span> (or </span><span>9<span>12</span></span><span>).</span>
