<u>Answer:</u>
Point Q lies on the circumference of the circle.
<u>Step-by-step explanation:</u>
We are given a circle with the point C (4,3) as its center with a radius of 3.16 units and we need to figure which of the given point lies on the circumference of the circle.
We can find this by using the distance formula:
Distance between C and P = 
Distance between C and Q = 
Distance between C and R = 
Since the distance between the points C and Q equals to the radius of the circle, therefore point Q lies on the circumference of the circle.
<h3><u>Question:</u><u>-</u></h3>
A coca cola costs 150 yen. You buyed 30 bottles of cola and sold them at the price of 155 yen each. Find profit %
<h3><u>Answer</u><u>:</u><u>-</u></h3>
3.33%
<h3><u>Explanation</u><u>:</u><u>-</u></h3>
Cost price = ¥150
Selling price = ¥155
Total profit = Selling price - Cost price
→ = ¥155 - ¥150
→ = ¥5
Profit % = Profit × 100/cost price
️ = 5 × 100/150
️ = 10/3 = 3.33%
M = 135/19 and n = -5/19
You have to give them like terms so that when you eliminate they cancel out and you can solve. The easiest way to do so is by multiplying the top equation by -4 and the bottom by 3.
