Answer:
(22h - 8) centimeters
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
= 2{(9h - 1) + (2h - 4)}
= 2(9h - 1 + 2h - 4)
= 2(11h - 4)
= (22h - 8) centimeters
Hello :
the equation is : y -(-3) = 0(x-3)....(slope = 0 '<span>horizontal line')
y=-3</span>
Linear functions have no exponents higher than 1, and a graph that looks like a straight line. non-linear functions have at least one exponent higher than 1, and a graph that isn't a straight line
We know that sin2x=2sinxcosx
(search the net for proof if you wish)
So the original equation becomes
2sinxcosx-sinx=0
The two terms both have sinx that can be taken out to get:
sinx(2cosx-1)=0
This is true if sinx=0 or 2cosx-1=0 , rewritten: cosx=1/2
sinx=0 than x=2kπ
cosx=1/2 than x=π/3+2kπ
where k is an integer
