Find the midpoint between the two points (-11,-14) and (-40,22)

Mid = ( -51 / 2 ), 4

Step-by-step explanation:

Mid = ( x1 + x2,   y1 + y2 )

                /              /

                2             2

Mid = ( -11 + (-40)),   (-14 + 22 )

                /                      /

                2                    2

Mid = ( -51 ),   ( 8 )

            /           /

           2          2

Mid = ( -51 / 2 ), ( 4 )

I hope this helps!

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
