Given are the points A(0,1) and B(4,-7). Find an equation (the point-slope form is perfectly acceptable) of the perpendicular bisector of line segment AB

Step-by-step explanation:

Find the slope of the given line using the coordinates of A and B.

The slope:

Find the midpoint of segment AB:

The perpendicular line has a slope of 1/2 ( opposite-reciprocal of -2) and passes through the point (2, -3).

The equation of this line is:

Slope-intercept form:

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
