Answer: a,b, and c are the correct solutions
Step-by-step explanation:
You are substituting each (x,y) for the equation given. They must equal the same on both sides.
Answer:
<h3>2√3</h3>
Step-by-step explanation:
The standard equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the center of the circle
r is the radius of the circle
Given the equation (x - 7)^2 + (y + 13)^2 = 12
On comparing;
r² = 12
Take the square root of both sides
√r² = √12
r = √12
r = √4*3
r = 2√3
Hence the radius of the circle is 2√3
Answer:
10m/s,15m/s,20m/s,5m/s
Step-by-step explanation:
Speed = distance / time
a) distance = 100m , time = 10s
Speed = distance / time
Speed = 100m/10s
Speed = 10m/s
b) distance = 300m , time = 20s
Speed = distance / time
Speed = 300m/20s
Speed = 15m/s
c) distance = 700m , time = 35s
Speed = distance / time
Speed = 700m/35s
Speed = 20m/s
d) distance = 1000m , time = 200s
Speed = distance / time
Speed = 1000m/200s
Speed = 5m/s
