Step-by-step explanation:
From the question we are told that:
Radius
Co-ordinate of x axis at C
Let
x' represent the x axis
y' represent the y axis
Since the intercept across the radius has values on the x' and y' axis
Therefore
Generally the Trigonometric equation for cos x is mathematically given by
Generally the Trigonometric equation for sin x is mathematically given by
Since x is in the IV quadrant sin x is negative
Step-by-step explanation:
Given that a centre has an origin (0,0) and (5,7) at the edge.
What is the radius of the circle
This is a direct question, we can apply coordinate geometry by finding the distance between two point, .
From co-ordinate geometry, the distance between two points is
d =√[(x2-x1)² + (y2-y1)²]
So, applying this
Point 1 = (x1,y1) = (0,0)
Point 2 = (x2,y2) = (5,7)
The radius of the is
r = √[(x2-x1)² + (y2-y1)²]
r = √[(5-0)² + (7-0)²]
r = √[5² + 7²]
r = √(25 + 49)
r = √74
The correct answer is D
D. √74

A(5;-12); O(0;0)
r=OA=√(5²+12²)=√169=13
r=13
A(5;-12); O(0;0)
r=OA=√(5²+12²)=√169=13
r=13
