We can split this up into 3 rectangles. 2 vertical ones (8 x 3) and one horizontal one in the middle (5 x (8 - 5)

8 x 3 = 24
24 x 2 = 48

5 x (8-5) = 5 x 3 = 15

now add 48 + 15 = 63 cm^2

What is the cofunction of cos 2pi/ 9

fiasKO [112]

The cofunction of cos is sin(90-x)

90 degrees is equal to PI/2

The cofunction becomes sin(PI/2 - 2PI/9)

Rewrite both fractions to have a common denominator:

PI/2 = 9PI/18

2PI/9 = 4PI/18

Now you have sin(9PI/18 - 4PI/18)

Simplify:

Sin(5PI/18)

the total charge for a yearly internet movie rental membership is $231.A registration fee of $15 is paid up front and the rest i

Flura [38]

New members pay a fee of $18 per month.

Step-by-step explanation:

Given,

Yearly movie rental cost = $231

Registration fee = $15

1 year = 12 months

Let,

x be the fee per month.

12x+15=231

$12x=231-15\\12x=216$

Dividing both sides by 12

$\frac{12x}{12}=\frac{216}{12}\\x=18$

New members pay a fee of $18 per month.
