The expression 
is called as <u>option d)</u> Quartic Trinomial.
<u>Step-by-step explanation:</u>
The given expression is .
<u>To find the number of terms :</u>
- one-term polynomial is called a monomial
- two-term polynomial is called a binomial and
- three-term polynomial is called a trinomial
"The number of terms in the expression is Three."
<u>The three terms are as follows :</u>
⇒ First term is 
⇒ Second term is 15x³
⇒ Third term is 53x²
Therefore, the given expression is called a "trinomial" with respect to the number of terms in it.
<u>To find the degree :</u>
The degree of a polynomial is the highest of the degrees of the individual terms in it with non-zero coefficients.
Here, in this expression the highest degree is 4.
Fourth degree is known as "Quartic".
Now, combining the number of terms and degree in the given expression, it is known as "Quartic Trinomial" which is option D).
Given that the radius r of a circle is written as a function of the area A with the following equation:
![r=\sqrt[]{\frac{A}{\pi}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B%5D%7B%5Cfrac%7BA%7D%7B%5Cpi%7D%7D)
The domain of the above function is the area A of the circle.
This is because, in this context, the area is an independent and unique variable.
A is the input value.
Answer:
Step-by-step explanation:
11) strategy: since they tell us. indirectly, that the length of JK is the same as LM then we can set those two equal, solve for X and then.. when we have X we can figure out the lenght of JK and LM and then just divide that by 2 go get PK ( :0 Player Killer ??? no , not that PK)
solve JK and LM
3x + 23 =9x-19
42 = 6x
7 = x
now that we know x = 7 plug it into either equation to come up with the length of JK or LM . I'll pick JK just b/c it was 1st
3(7) + 23 = JK
21+23 = JK
44 = JK
now take half of 1/2*JK= 22 that is PK ( are you sure that 's not player killer?)
PK = 22
12) strategy: set the two arcs BG and GC equal and solve for X, then plug x into either equation and the multiply the answer by 2 to find arc AB
9x-20 = 5x + 28
4x = 48
X = 12
9(12) -20 = BG
88 = BG
2*88 + AB
176 = AB
13) done
14) strategy: find the angle at L, and that will also be the arc of MK
<em>copy and past the below</em> helpful trig functions into your computer
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
<em>copy and past the above</em> :
use which ever trig function you want , we have all the sides of the triangle, I'll use CAH
Cos(Ф) = 9/15
Ф = arcCos(9/15)
Ф = 53.13010°
arc MK = 53.13010°
15) strategy: arc JK is just 2 times MK
2*MK = 106.26020°
arc MK = 106.26020°
16) find arc JPK strategy: JPK is just the remaining part of a full circle of 360 - MK = 253.7397°
arc JPK = 253.7397°
