Answer:
Yes, it is a function
Step-by-step explanation:
A function is a set of ordered pairs where there is no two of the same domain. The domain is the first coordinate which is x. In this case, the x coordinates are 4, 0, 11, 17. There is no two of the same domain so this is a function.

Answer:
x = 97.6
Step-by-step explanation:
cos = adjacent over hypotenuse

* multiply each side by x *

* divide each side by cos ( 55 ) *

we're left with x = 97.63302055
Our last step is to round to the nearest tenth of a foot
We get that x = 97.6
Answer:
Actually it's not polygon. it's a nonagon. With r=8.65mm″, the law of cosines gives us side a:
a=√{b²+c²−2bc×cos40°}
a=√{149.645−149.645cos40°}
Area Nonagon = (9/4)a²cos40°
=9/4[149.645−149.645cos40°]cot20°
=336.70125[1−cos(40°)]cot(20°)
Applying an identity for the cos(40°) does not get us very far…
= 336.70125[1−(cos2(20°)−1)]cot(20°)
= 336.70125[2−cos2(20°)]cot(20°)
= 336.70125[2−(1−sin2(20°))]cot(20°)
= 336.70125[1+sin2(20°)]cos(20°)sin(20°)
= 336.70125[cot(20°)+sin(20°)cos(20°)]mm²
The volume of the fourth box is of 410.1 cubic inches.
---------------------
The volume of a rectangular prism is given by the <u>base area multiplied by the height,</u> that is:

---------------------
- For the first three boxes, the height is constant at 9 inches.
- At the base, the <u>edge length is multiplied by 1.5</u> each time, as
, thus, for the fourth box, the edge length, in inches, will be of 
---------------------
- Square base, of<u> length 6.75 inches</u>, thus:

- Height of <u>9 inches</u>, thus
and:

The volume of the fourth gift box will be of 410.1 cubic inches.
