Klio2033 [76]

Answer:

1.) 2/5

2.) -7/5

Step-by-step explanation:

Slope Formula: m = y2 - y1/x2 - x1

1.) 2/5

m = y2 - y1/x2 - x1

m = -1 - (-3)/0 - (-5)

m = -1 + 3/0 + 5

m = 2/5

2.) -7/5

(-2,3) and (3,-4)

m = y2 - y1/x2 - x1

m = -4 - 3/3 - (-2)

m = -4 - 3/3 + 2

m = -7/5

Area of a regular hexagon with an apothem of 15 cm
Anton [14]

Answer:

area = 779.4 cm²

Step-by-step explanation:

divide it into 6 equal equilateral triangles. Each corner of a triangle will be 60°.

tan 60° = 15/x

1.7321 = 15/x

x = 8.66 (this is one-half of the base of the triangle)

base = 17.32 cm

area of one triangle = 1/2(17.32)(15) = 129.9 cm²

129.9(6) = 779.4 cm²   (because 6 triangles make up the hexagon)
