An=a1(r)^(n-1)
an=5(-3)^(n-1)
so then each term is multiplied by -3

so
f(n)=-3(f(n-1))
and
f(n)=5

Please help! i'm confused!<br> Find the area of a kites with diagonals 9in and 12in.
kolbaska11 [484]
Notice the picture
the rhombus, or kite, is really just 4 triangles
all sides are the same lenght in a rhombus,

thus, find the area of all of the triangles,
and you already have two sides given,
and then, add them up

or just find the length of one, and multiply times 4 :)

recall, area of a triangle = 1/2 bh

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)
