I really need help with these two questions. I wrote what I think they are, but I'm not sure. Please help me double check them.

1. The first polynomial listed is just the number 9.

We can identify two key things here:

There is one term, so it's a monomial.

There are no factor's, so it has a degree of 0, or is constant.

Your answer is correct.


2. In the next polynomial, we can identify the same things:

There are three terms, so it's a trinomial.

The degree of the polynomial is determined by observing the higher power in a given term, in this case, it's three.

The prefix for relating to a multiple of three is cubic, we so know that this is a cubic trinomial.

Your answer is correct again, well done!

Answer:

central angle=18

arc length=2.5 π feet

area of a sector=31.25π square feet

Step-by-step explanation:

Given

wheel radius=25 feet

attached cars=20

Space between cars along the circumference of wheel= 360/20

                                                                                          =18

Finding arc length:

arc length= radius x angle(in radians)

 angle in radian = 18 x π/180 = 0.1π radians

arc length   = 25 x 0.1π

                 =2.5π feet  

Area of the circle = πr^2

Area of the circle = π(25)^2

Area of the circle = 625π square feet.  

As the ratio of the central angle to the full circle angle is proportional to the area of the sector to the complete circle:

central angle/360=area of sector/area of circle

Area of sector= area of circle x 18/360

                       = 625π(1/20)

                        =31.25π !

7 < 2x = 25
6x + 12 > 32 (put a line under the greater than sign)
x/5 = 22
18 < 3/4b = 23
