Answer:
3
Step-by-step explanation:
because if you look closely at the graph you see
The value of the length of the rhombus will be found as follows:
cos θ=adjacent /hypotenuse
θ=108/2=54°
adjacent = 9/2=4.5 inch
hypotenuse=length of the rhombus
thus
cos 54=9/x
x=4.5/cos 54
x=7.6558~8 inches
the answer is 8 inches
ANSWER
Domain:

Range:

EXPLANATION
The domain refers to the values of x for which the function is defined.
The least value of x is 0.
Therefore the domain is
![[0,\infty]](https://tex.z-dn.net/?f=%5B0%2C%5Cinfty%5D)
.
or

The range refers to values of y for which x is defined.
The highest value on the y-axis that the graph can attained is 4. The function decreases without bound.
There the range is
![(- \infty,4]](https://tex.z-dn.net/?f=%28-%20%5Cinfty%2C4%5D%20)
.
or
A = l²
A = 7.2²
A = 51.84
51.84 inches
