the first question is 7.87

Thanks :D

i think the next question is 150

Point A is at (3, 2.7) and point B is at (3, 1.4) on a coordinate grid. The distance between the two points is ____. Input numbers and decimal point only, such as 5.8.

OpenStudy (anonymous):

The coordinates of point P on a coordinate grid are (−5, −6). Point P is reflected across the y-axis to obtain point Q and across the x-axis to obtain point R. What are the coordinates of points Q and R? Q(5, 6) and R(−5, −6) Q(−5, −6) and R(5, 6) Q(−5, 6) and R(5, −6) Q(5, −6) and R(−5, 6)

For unit conversion: See this video: https://www.khanacademy.org/math/pre-algebra/rates-and-ratios/metric-system-tutorial/v/unit-conversion As for finding the distance between points you just use Pythagorean theorem \[( (x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2 )^{\frac{1}{2}} = distance\] see: http://www.purplemath.com/modules/distform.htm For the last problem you posted I recommend graphing the point, also by reflected it means that if you were to fold the graph paper in half along the y axis both points would be overlapping for example: |dw:1438134584455:dw|

OpenStudy (anonymous):

Oh ok ill watch the videos thanks :D

OpenStudy (australopithecus):

I made a mistake in the graph, as far as the coordinates If you were reflect the point (2,1) about the y axis you would get point (-2,1) |dw:1438134703836:dw|
