Find the distance between (6,2) and (9,12)

bazaltina [42]

Distance bweteen (x1,y1) and (x2,y2) is
$D= \sqrt{(x2-x1)^2+(y2-y1)^2}$

so disatnce between (6,2) and (9,12) is
$D= \sqrt{(9-6)^2+(12-2)^2}$
$D= \sqrt{(3)^2+(10)^2}$
$D= \sqrt{9+100}$
$D= \sqrt{109}$

the distance is√109 units

PLEASE HELP ASAP WILL MARK BRAINLIEST

garik1379 [7]

Answer:

A (the marked answer is correct)

Step-by-step explanation:

The result of a single refection will look like the reverse of the letter Z, so the only possibilities are choices A and C.

Since the horizontal lines are still horizontal, the reflection must be across a horizontal or vertical line. If the reflection is across a horizontal line, the image will be vertically aligned with the preimage. If the reflection is across a vertical line, the image will be horizontally aligned with the preimage.

Choice A is horizontally aligned with the preimage. Choice C is not aligned either way. (It is a "glide reflection.")

Image A is the result of reflection across the y-axis.

Someone please answer and explain this for me!

Nesterboy [21]

Hello!

To find our answer, we will want to multiply our circumference by 15. The reason why is because the circumference is the distance around the circle, or tire in this case. If it goes around 15 times it will have traveled this distance 15 times.

Therefore, we find our circumference, multiplying pi by our diameter. It appears that the total height is 26 in.

26 $\pi$ ≈81.68

Note that it wants us to round for the nearest FOOT. Therefore, we divide our answer by 12 and round to the nearest whole number.

81.68/12≈6.81≈7

Therefore, it will have traveled 7 feet.

I hope this helps!
