We are asked to determine the lengths of the line segment drawn with these points as endpoints. The equation of the distance between points is,
d = sqrt ((y2 - y1)² + (x2 - x1)²)
Substituting the coordinates of the points,
d = sqrt ((14 - 9)² + (4 - 2)²)
The numerical value for d is approximately 5.39.

Say that a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse. Find b if a = 21 and c =

maria [59]

When the triangle is a right triangle, you can use the Pythagorean theorem. The formula would be

c^2 = a^2 + b^2

If a = 21 and c=29, thus

b^2 = c^2 - a^2
b^2 = 29^2 - 21^2
b^2 = 400
b = square root (400)
b = 20 units.

Thus, the answer is D) B = 400

Tell whether the given value is a solution of the inequality. a/6 > -4; a = -18

balandron [24]

First we simplify the inequality

1. multiply 6 by the other side of the inequality (-4)

Now we have ...

a > -24

Anything that can be a solution to the inequality must be greater than -24

-18 is greater than -24

This means that, YES! a = -18 IS a solution to the inequality
