Answer:
The answer to your question is x² + y² - 8x - 6y = 0
Step-by-step explanation:
Data
P (1, 7)
Q (8, 6)
R (7, -1)
Use the general equation of the Circle
x² + y² + Dx + Ey + F = 0
Process
1.- Substitute each point in the general equation and simplify
For P
(1)² + (7)² + D + 7E + F = 0
1 + 49 + D + 7E + F = 0
50 + D + 7E + F = 0
D + 7E + F = -50 Equation l
For Q
(8)² + (6)² + 8D + 6E + F = 0
64 + 36 + 8D + 6E + F = 0
100 + 8D + 6E + F = 0
8D + 6E + F = -100 Equation ll
For R
(7)² + (-1)² + 7D - E + F = 0
49 + 1 + 7D - E + F = 0
50 + 7D - E + F = 0
7D - E + F = -50 Equation lll
Solve the system of equations, I do not include the process but the solutions are
D = -8 E = -6 F = 0
-Substitution
x² + y² - 8x - 6y = 0
This is a division problem.
You need to divide 3/5 by 5.
(3/5) / 5 = (3/5 / (5/1) = 3/5 * 1/5 = 3/25
At first let us choose the 5 points
at x = 0, y = 0
The first point is (0, 0)
![y=ax^3](https://tex.z-dn.net/?f=y%3Dax%5E3)
We will choose a = 1/2
The points are
(-2, -4)
(-1, -1/2)
(0, 0)
(1, 1/2)
(2, 4)
Answer:
7%
Step-by-step explanation:
you take the $800 (beauty products she sold) and multiply it by 7% you come up with your commission of $56
Answer:
a) 53%
b) 58%
Step-by-step explanation:
a) (18+35)/100 × 100 = 53%
b) (35+23)/100 × 100 = 58%
