If point A is located at (0, -8) and B is located at (4, -5), what is the distance between them?
A. 5
B. 6
C. 7
D. 8
I know I don't usually ask for just the answer (I generally give what I got) but this was due on the 6th! I was in the hospital for pneumonia, and I didn't realize how behind I was in algebra. Please, please help as soon as possible!!
Please, please don't ban me. I just really need this. I'm panicking (I know, I'm such a suck-up), just please don't ban me. I'm not trying to cheat.
d =sqrt [ (y2-y1)^2 +(x2-x1)^2 ]
d =sqrt [ (-5 +8)^2 +(4-0)^2 ]
= sqrt [ 9+16 ]
= sqrt 25
Goodness, thank you.
You are welcome.
However when in danger or in doubt
SKETCH A PICTURE of it !
If you had done it, you would have seen the right triangle immediately.
Thanks it really helped me with this math equation
To find the distance between two points on a Cartesian coordinate plane, you can use the distance formula. The distance formula is derived from the Pythagorean theorem and is given by:
d = √((x2 - x1)^2 + (y2 - y1)^2)
In this case, point A is located at (0, -8) and point B is located at (4, -5). Let's substitute these coordinates into the distance formula:
d = √((4 - 0)^2 + (-5 - (-8))^2)
= √(4^2 + (-5 + 8)^2)
= √(16 + 3^2)
= √(16 + 9)
= √25
= 5
Hence, the distance between points A and B is 5 units.
Therefore, the correct answer is A. 5.
