Answer:
0
Step-by-step explanation:
Slope = Δy/Δx
Slope = 10-10/4-1
Slope = 0/3
Slope = 0
It is a Horizontal Line

Answer:
![(x+1)^2 + (y + 1)^2 = 13](https://tex.z-dn.net/?f=%28x%2B1%29%5E2%20%2B%20%28y%20%2B%201%29%5E2%20%3D%2013)
Step-by-step explanation:
<u><em>To find the centre of the circle, find the mid - point of PQ :</em></u>
<u><em /></u>![Centre =( \frac{x_1+x_2}{2} \ , \ \frac{y_1 + y_2}{2}) = (\frac{-2}{2} \ , \ \frac{-2}{2}) = (-1, -1)](https://tex.z-dn.net/?f=Centre%20%3D%28%20%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%20%5C%20%2C%20%5C%20%5Cfrac%7By_1%20%2B%20y_2%7D%7B2%7D%29%20%3D%20%28%5Cfrac%7B-2%7D%7B2%7D%20%5C%20%2C%20%5C%20%5Cfrac%7B-2%7D%7B2%7D%29%20%3D%20%28-1%2C%20-1%29)
<em><u>Diameter = 2 x Radius , To Find the diameter, find distance between P and Q:</u></em>
<em><u /></em>
<em><u /></em>
![= \sqrt{6^2 + 4^2} = \sqrt{36+ 16} = \sqrt{52} = \sqrt{4 \times 13} = 2 \times \sqrt{13}](https://tex.z-dn.net/?f=%3D%20%5Csqrt%7B6%5E2%20%2B%204%5E2%7D%20%20%3D%20%5Csqrt%7B36%2B%2016%7D%20%3D%20%5Csqrt%7B52%7D%20%3D%20%5Csqrt%7B4%20%5Ctimes%2013%7D%20%20%3D%202%20%5Ctimes%20%5Csqrt%7B13%7D)
PQ is the diameter , therefore radius :
![r = \frac{1}{2} \times 2 \sqrt{13} = \sqrt{13}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%202%20%5Csqrt%7B13%7D%20%20%3D%20%5Csqrt%7B13%7D)

Answer:
8.5
Step-by-step explanation:
58.65/6.9= 8.5
The cost of the car is $27,546
<h3>How to calculate the cost of the car ?</h3>
The sales tax is 7%
Jorge bought a ford mustang having a sales tax of $1,928.22
Therefore the cost of the car can be calculated as follows
7/100 = 0.07
1928.22/0/07
= 27,546
Hence the cost of the car is $27,546
