To calculate the distance between two points on the coordinate system you have to use the following formula:
Where
d represents the distance between both points.
(x₁,y₁) are the coordinates of one of the points.
(x₂,y₂) are the coordinates of the second point.
To determine the length of CD, the first step is to determine the coordinates of both endpoints from the graph
C(2,-1)
D(-1,-2)
Replace the coordinates on the formula using C(2,-1) as (x₁,y₁) and D(-1,-2) as (x₂,y₂)
The length of CD is √10 units ≈ 3.16 units
Answer:
p = 8
Step-by-step explanation:
Given that,
42p = 414
We need to find the value of p. It can be done by dividing both sides by 42. So,
Out of the given options, option (b) i.e. 8 is the nearest option. So, the value of p = 8.
