What is a degree of a polynomial?

A polynomial is an expression that has more than two algebraic terms.

The degree of a polynomial is the value of the highest power in the given polynomial.

Example:

x³ + 2x² + 4x + 3 is a polynomial.

x³ + 5x² + 8x + 3 is a polynomial.

The degree is 3.

We have,

2 $x^(4)$ - 3 $x^(5)$ + x

This is a polynomial since it has more than two algebraicterms.

The highestpower of the algebraicterms given is 5.

$x^(4)$ , $x^(5)$ , and x are the algebraicterms in the given polynomial.

Thus,

The degree of the polynomial 2 $x^(4)$ - 3 $x^(5)$ + x is 5.

Write a function rule that represents the sentence
y is 5 less than the product of 4 and x.

Answers

y=5-4x
since less than is subtraction
is means equals
and product means you have to multiply the numbers

Final answer:

The function rule to represent the given sentence is y = 4x - 5.

Explanation:

To write a function rule that represents the sentence 'y is 5 less than the product of 4 and x,' we can use algebraic notation. The word 'less than' indicates a subtraction operation, so we can represent it as y = 4x - 5. In this function rule, 4x represents the product of 4 and x, and subtracting 5 from it gives us y.

The value of √-9 is not -3 because_______.A. 9^2 not congruent to -3
B. (-3)^2 not congruent to -9
C. 3^2 not congruent to -9
D. (-9)^2 not congruent to -3

Answers

B, because -3^2 is not -9. -3*-3 = 9, square roots of negative numbers aren't possible, because no number squared can be equal to them. Instead, they are expressed in terms of "i", which is defined as

i^2 = -1

The value of √-9 is not -3 because B. (-3)^2 not congruent to -9.

This is the answer because, (-3)^2 = 9 NOT -9. Any negative squared is equal to the positive squared. E.g. 2^2=4 & (-2)^2=4. Another tip is that in the number in the square root sign is negative the answer is no solution as it is impossible to square a number and get a negative answer.

The director of marketing at a large company wants to determine if the amount of money spent on internet marketing is a good predictor of company profit. She fits a least-squares regression line to 20 months of data and computes the following regression line:Profit = 372.6 + 17.2(advertising dollars)

What is the value of the residual for advertising dollars spent equal to $1,020 and Profit equal to $17,500? Round to the nearest integer.

Answers

Given:
Profit = 17,500
advertising dollar = 1,020

regression line:

Profit = 372.60 + 17.2(advertising dollar)
17,500 = 372.60 + 17.2(1020)
17,500 = 372.60 + 17,544
17,500 = 17,916.60

There is a residual value of 416.60.

17,916.60 - 17,500 = 416.60

What are the zero(s) of the function f(x) = the quantity of 5 x squared minus 25 x, all over x? x = 5 x = 0 and x = 5

Answers

Answer:

x=5

Step-by-step explanation:

$f(x)= (5x^2-25x)/(x)$

To find out zeros we replace f(x) with 0

$0= (5x^2-25x)/(x)$

Now solve for x

first we divide the numerator by x

$0=5x-25$

Now we facor out GCF 5

$0=5(x-5)$

Divide by 5 on both sides

$0=x-5$

Add 5 on both sides

x= 5

zero of the function is x=5

(5x^2-25x)/x
simplify
((x)(5)(x-5))/x=5(x-5)=5x-25=f(x)
(just fyi, that x we cancled is a hole)
set to zero
5x-25=0
5x=25
divide 5
x=5

zeroe is at x=5
or (5,0)

x=5 is answer
