Answer:
<h2>a) center (2, -3)</h2><h2>b) radius r = 3</h2><h2>c) in the attachment</h2>
Step-by-step explanation:
The standard form of an equation of a circle:

(h, k) - center
r - radius
We have:

a) center (2, -3)
b) radius r = 3
c) in the attachment
3(18 - x/3 = -7)
54-x = -21
-x = -75
x = 75
Answer: 75% 45/60 is .75 witch is 75%
Step-by-step explanation:
Given :
A boat is located a sea level. A scuba diver is 80 feet along the surface of the water from the boat and 30 feet below the water surface.
A fish is 20 feet along the horizontal plane from the scuba diver and 10 feet below the scuba diver.
To Find :
The slope between the scuba diver and fish.
Solution :
Horizontal distance between diver and fish is 20 feet.
Fish is 10 feet below the scuba diver.
Slope between scuba diver and fish is :

Therefore, the slope between the scuba diver and fish is 0.5 .
83 1/3 % = 5/6 so
20 = (5/6)x
x = (6/5)(20) = 24
