Answer:
Step-by-step explanation:
We want to find equation of a circle with center (-4,6) and radius 9cm.
The equation of a circle with center (h,k) and radius units is given by;
We substitute the radius and the center to obtain;
The required equation is:
Answer:
The distance between Harry’s home and his office? is 15 miles.
Step-by-step explanation:
The speed, distance time formula is:
Given:
Speed (<em>s</em>) = 30 miles/hour
Then the relation between distance and time is:
If Speed was 60 miles/hour the time taken is hours.
Then the relation between distance and time is:
Use the value of <em>d</em> = 30t in (ii)

Determine the distance as follows:
Thus, the distance between Harry’s home and his office? is 15 miles.
