It's 3, I believe. Divide both point "A"'s buy each other
Answer:
Distance between point
and midpoint of line joining
and
=
units.
Step-by-step explanation:
Given:
Points:
![A(3,4)\\B(8,10)\\C(4,6)](https://tex.z-dn.net/?f=A%283%2C4%29%5C%5CB%288%2C10%29%5C%5CC%284%2C6%29)
To find distance from point A to midpoint of BC.
Midpoint M of BC:
![M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%5Cfrac%7By_1%2By_2%7D%7B2%7D%29%5C%5C)
[Plugging in points
]
![M=(\frac{12}{2},\frac{16}{2})\\](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7B12%7D%7B2%7D%2C%5Cfrac%7B16%7D%7B2%7D%29%5C%5C)
![M=(6,8)\\](https://tex.z-dn.net/?f=M%3D%286%2C8%29%5C%5C)
Distance between A and M:
![D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D%20%5C%5C)
[Plugging in points
]
![D=\sqrt{(3)^2+(4)^2} \\](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%283%29%5E2%2B%284%29%5E2%7D%20%5C%5C)
![D=\sqrt{9+16} \\](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B9%2B16%7D%20%5C%5C)
![D=\sqrt{25} \\](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B25%7D%20%5C%5C)
![D=\pm5](https://tex.z-dn.net/?f=D%3D%5Cpm5)
Since distance is always positive ∴
units

Subtraction
(left to right)
4²-(3.1+6.4)+4.5
According to PEMDAS, we will do what is inside the parenthesis.
3.1+6.4 = 9.5
<em>4²-9.5+4.5</em>
Then we do figure out the exponent.
4² = (4)(4) = 16
<em>16-9.5+4.5</em>
Then we do subtraction then addition because PEMDAS also tells us we should do adding and subtracting from left to right. In this expression, subtracting is on the left side so we should do that first.
16-9.5 = 6.5
<em>6.5 + 4.5 = 11</em>
11 is your answer :)
Answer:
Yes it can be be the reflected figure
