Answer:
13. 9.77 inches (rounded to 3 s.f.)
14. 249m² (rounded to 3 s.f.)
Step-by-step explanation:
13. To find the arc length, the formula is the angle of the arc out of 360° multiplied by the circumference of the full circle. Circumference of circle: pi × r × 2
× pi × 7 × 2 = 3
pi
= 9.77 inches (rounded to 3 s.f.)
14. To find the sector area, the formula is the angle of the sector out of 360° multiplied by the area of the full circle. Area of circle: pi × r × r
× pi × 10 × 10 = 79
pi
= 249m² (rounded to 3 s.f.)
(2x-1)(x+4)=0
Step-by-step explanation:
A random zero property of multiplication is taken to find the solution
(2x-1)(x+4)=0
consider a=2x-1 and b=x-4 a.b=0
either a or b or both must be 0
equating both the equations
2x-1=0 or x=4=0 x-4=0
2x-1=0 x=4
2x=1
x=1/2
substitute the values of x in the main equation
[2(1/2)-1][(1/2)+4]=0
I know the answer is 22.2
The statement that: pairs of corresponding points lie on parallel lines in a reflection, is false.
<h3>What are reflections?</h3>
When a point is reflected, then the point is flipped across a point or line of reflection
When a point is reflected, the following highlights are possible
- The corresponding points can line on the same line
- The corresponding points can line on parallel lines
Using the above highlights, we can conclude that the statement is false.
This is so because, corresponding points are not always on parallel lines

Smaller because it's basicly like a fraction and and the bigger the number the smaller the piece
