If the following is a polynomial function, then state its degree and leading coefficient. If it is not, then state this fact. f(

Fed [463]

By definition, a polynomial is an expression with more than one term. That is a monomial. We have names for 2-termed polynomials (binomials) and 3-termed polynomials (trinomials), but that's where the naming stops and they all are called polynomials after that. Our degree is the same as the highest exponent. So our degree is a fifth degree. The leading coefficient is the number that starts out the whole polynomial AS LONG AS IT IS IN STANDARD FORM. If our polynomial started with the -4x^4, our leading coefficient would NOT be -4 since the highest degree'd term will always come first in standard form. Your choice for your answer is the first one given. Degree: 5 Leading Coefficient: -13.

in base ten, the two-digit prime N is 45 more than the number formed by reversing the digits of N, find all the possible values

Drupady [299]

Let $N=10x+y$ , so that $x$ is the digits in the tens place and $y$ is the digit in the ones place. (Clearly $x\neq0$ .)

$10x+y=45+10y+x\implies 9x-9y=45\implies x-y=5$

There are five possible two digits integers that satisfy this relation:

$x=5,y=0\implies N=50$
$x=6,y=1\implies N=61$
$x=7,y=2\implies N=72$
$x=8,y=3\implies N=83$
$x=9,y=4\implies N=94$

But the first, third, and fifth candidates are even, so they are not prime. The remaining are prime, however, so $N=61$ or $N=83$ .

Two types of tickets are available for a charity ball event: $18 for a reserved seat and $9 for general admission. The number of

Murljashka [212]

Answer:

# of reserved seats = R; # of general admission seats = G

G - R = 85

$18R + $9G =$3600

Multiply 1st equation by 18: 18G - 18R = 1530

Rearrange 2nd equation: $9G + $18R =$3600

Combine the equations: 27 G = 5130

G = 190

R = 105

Separate 846 into 3 parts so that the second part is twice the first part and the third part is triple the second part. Which of

saveliy_v [14]

Let us assume the first part to be = x
Then
The second part will be = 2x
The third part will be = 3 * 2x
   = 6x
Then we can get to the equation
x + 2x + 6x = 846
9x = 846
x = 846/9
   = 94
So
The first part will be = 94
The second part will be = 2x
   = 2 * 94
   = 188
The third part will be = 6x
   = 6 * 94
   = 564
So the three parts are 94, 188 and 564.The second option of 846 = x + 2x + 6x is the correct option.
