The proof that point (1,3) lies on the circle that is centered at the origin and
contains the point (0, 2) is found in the table below. What is the justification
for the 5th statement?
Statement
Justification
A circle is centered at (0, 0) and
contains the point (0, 2).
Given
Definition of radius
The radius of the circle is the distance
from (0, 0) to (0, 2).
The distance from (0, 0) to (0, 2) is
VO-D) +(2-0) - 127-2
Distance formula
Definition of a circle
If (1, 3) lies on the circle it must be
the same distance from the center as
(0, 2).
The distance from (1, 3) is
VO - 1)2 - (0-3)? - v1+3 - 2
Since (1, 3) is 2 units from (0, 0), it
lies on a circle that is centered at the
Definition of a circle
Answers
The justification for the 5th statement regarding the circle is the distance formula.
How to depict the formula?It should be noted that the distance between the points will be found based on the information given.
From the information given, the distance from (0, 0 to (0, 2) will be:
= [tex]\sqrt{0 - 0}[/tex]² + [tex]\sqrt{2 -0}[/tex]²
= 4
= 2
In this case, the justification is the distance formula.

Answer:
5 = y
6.5 = x
Step-by-step explanation:
Since all the angles are the same, you can determine that all the sides are the same lengths.
8 = y + 3
8 - 3 = y
5 = y
8 = 2x - 5
8 + 5 = 2x
13 = 2x
13/2 = x
6.5 = x
Answer:
2x - 5 = 8
+5 +5
2x = 13
Divide by 2 on both sides:
X = 6.5
Y + 3 = 8
-3 -3
Y = 5
They must equal 8 since all sides are the same.

if there are 300 calories in 100 g of a certain food, how many calories are there in a 30 g portion of food
Answers
Answer:
90 calories
Step-by-step explanation:
Calories : quantity of food
there are 300 calories in 100 g of a certain food
300 calories : 100 g food
how many calories are there in a 30 g portion of food
Let x = number of calories
x calories : 30 g food
Equate both ratios
300 calories : 100 g food = x calories : 30 g food
300/100 = x/30
300 * 30 = 100 * x
9000 = 100x
x = 9000/100
x = 90
x = number of calories = 90 calories
