Answer:
![||AB||=\sqrt{65}](https://tex.z-dn.net/?f=%7C%7CAB%7C%7C%3D%5Csqrt%7B65%7D)
Step-by-step explanation:
If you have two points:
![A=(x_1,y_1,z_1)\\B=(x_2,y_2,z_2)\\\\||AB||=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}](https://tex.z-dn.net/?f=A%3D%28x_1%2Cy_1%2Cz_1%29%5C%5CB%3D%28x_2%2Cy_2%2Cz_2%29%5C%5C%5C%5C%7C%7CAB%7C%7C%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%2B%28z_2-z_1%29%5E2%7D)
Then, we have:
![A=(1,2,3)\\B=(-3,2,-4)](https://tex.z-dn.net/?f=A%3D%281%2C2%2C3%29%5C%5CB%3D%28-3%2C2%2C-4%29)
And we have to <em>calculate</em> ![||AB||](https://tex.z-dn.net/?f=%7C%7CAB%7C%7C)
![||AB||=\sqrt{(-3-1)^2+(2-2)^2+(-4-3)^2}\\\\||AB||=\sqrt{(-4)^2+(0)^2+(-7)^2}\\\\||AB||=\sqrt{16+49} \\\\||AB||=\sqrt{65}](https://tex.z-dn.net/?f=%7C%7CAB%7C%7C%3D%5Csqrt%7B%28-3-1%29%5E2%2B%282-2%29%5E2%2B%28-4-3%29%5E2%7D%5C%5C%5C%5C%7C%7CAB%7C%7C%3D%5Csqrt%7B%28-4%29%5E2%2B%280%29%5E2%2B%28-7%29%5E2%7D%5C%5C%5C%5C%7C%7CAB%7C%7C%3D%5Csqrt%7B16%2B49%7D%20%5C%5C%5C%5C%7C%7CAB%7C%7C%3D%5Csqrt%7B65%7D)
The answer is:
![||AB||=\sqrt{65}](https://tex.z-dn.net/?f=%7C%7CAB%7C%7C%3D%5Csqrt%7B65%7D)
Answer:
No
Step-by-step explanation:
Q=78
R=40
S=62
T=42
U=76
180-42-62=76
180-78-62=40
Answer:
<h2>See the explanation.</h2>
Step-by-step explanation:
Here, an equation of straight line is given.
The equation is
.
If you put x = 0, in the above equation, you will get y = 0.
Hence, the equation passes through (0, 0).
Again if we put, x = 1 in the above equation, we will get y = - 1.5.
It means the equation also passes through (1, -1.5).
Joining these two points, you can graph the straight line.
