Answer:

A(x)=7x^2-2x+10

Step-by-step explanation:

Long Division

The polynomial long division implies the sequential division of each term of the dividend polynomial by the terms of the divisor polynomial. The procedure is a well-know sequence of steps from which there are two outputs: the quotient and the remainder.

We have two mathematical models, one for the total number of visitors who went to a theme park:

F(x)=126x^3+279x^2+90x+450

The other for the number of shows played at the theme park in the same period

G(x)=18x+45

Where x is the number of days since October 1. We are required to find the expression for the average number of visitors per show. It comes by dividing F(x) by G(x). We must perform a long division as shown  below.

The average number of visitors per show is

A(x)=7x^2-2x+10

For example, day 5

A(5)=7\ 5^2-2(5)+10=175

There were 175 visitors per show (on average)

The price of an item has dropped to $39 today. Yesterday it was
Kobotan [32]

Answer:

40% decrease

Step-by-step explanation:

First, let's find the value decrease of the item from yesterday to today

$65 - $39 = $26

That means that $65 was 100% of the price and decreasing it by 26 gets us to 39

We need to find the percentage of 39 in 65

39/65 = 0.6 or 60%

If 39 is 60% of 65, then there was a 40% decrease form 100%

To check we can calculate the percentage of 26 in 65:

26/65 = 40%

There was a 40% decrease

Which relation is a function?
zimovet [89]

Answer:

D

Step-by-step explanation:

A relation is a set of related points. A function is a set of related points where no inputs repeat.

A. {(1, 2), (2, 3), (3,  2), (2, 1)}

This repeats (2,3) and (2,1). Not a function.

​B. {(4, 2), (3, 3), (2,  4), (3, 2)}  

This repeats (3,3) and (3,2). Not a function.

C. {(1, −1), (−2, 2), (−1,  2), (1, −2)}

This repeats (1,-1) and (1,-2). Not a function.

D. {(1, 4), (2, 3), (3,  2), (4, 1)}

This doe NOT repeat. Function.

Please help I have a quiz soon
Novay_Z [31]

Answer:

The option that no represent a linear function is f(x)=3^x

Step-by-step explanation:

we know that

The graph of a linear function is a straight line

The equation of a linear function in slope intercept form is equal to

f(x)=mx+b

where

m is the slope

b is the y-intercept

<u><em>Verify each case</em></u>

option 1) we have

f(x)=3x-2

This option represent a linear function

where

m=3

b=-2

option 2) we have

f(x)=x

This option represent a linear function

where

m=1

b=0

This option represent a linear direct variation function

option 3) we have

f(x)=3^x

This option not represent a linear function

This option represent a exponential function

option 4) we have

f(x)=3x

This option represent a linear function

where

m=3

b=0

This option represent a linear direct variation function
