Answer:

Step-by-step explanation:
we are given a function

we would like to simplify it for h(-1)
in order to do so
substitute the value of x

by order of PEMDAS
simplify square:

simplify multiplication:

simplify addition:

simplify subtraction:

reduce fraction:

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)
Well there are no specific numbers, but the area of a rectangle is the length x the width, and the width is the area ÷ the length.
N(1/3)-8=-13 is the correct answer.
