Cos θ = adj/hyp = 5/sqrt(5^2 + (-12)^2) = 5/sqrt(25 + 144) = 5/sqrt(169) = 5/13

I need to find the shaded part of this shape help I'm confuzzled

You just have to imagine it as a rectangle, with a square.

The rectangle inside is 18" by 8".

The square, made of the outside two triangle pieces, is 8" by 4". (Yes, I know it isn't really a square.)

Area = length x width.
A1 = 18 x 8
= 144.
A2 = 8 x 4
= 32.
A1 + A2 = 176 square inches.

Find the compound interest earned by the deposit of $1800 at 6% compounded quarterly for 6 years.

Delvig [45]

For compound interest questions know the formula , after that just substitute accordingly
if the question is asking for the interest , do not forget to subtract off the amount you started with
