here is a graph of a polynomial function with degree 4 what statements are true about the function?

Answers

The leading coefficient is positive (starts and ends positive given an even degree polynomial)

It has 4 linear factors (the graph crosses the x-axis at 4 places)

One of the zeroes is x=2 (the graph crosses the x-axis at x=2)

The statements that are true about the functions are:

The leading coefficient is positive.

It has two relative maximums

It has four linear factors.

One of the zeroes is x = 2.

What is a polynomial?

Polynomial is an equation written as the sum of terms of the form kx^n.

where k and n are positive integers.

We have,

From the graph,

The graph passes through the following points on the graph.

x = -4

x = -2

x = 2

x = 6

This means the polynomial function is:

P(x) = (x + 4)(x + 2)(x - 2)(x - 6)

If we simplify the polynomial we get,

P(x) = (x² + 2x + 4x + 8) (x² + 6x - 2x + 12)

P(x) = [tex]x^{4}[/tex] + 6x³ - 2x³ + 12x² + 2x³ + 12x² - 4x² + 24x + 4x³ + 24x² - 8x² + 48x + 8x² + 48x - 16x + 96

P(x) =[tex]x^{4}[/tex] + 10x³ + 44x² + 104x + 96

The leading coefficient is positive 1 so it is positive.

The constant term is a positive number (96).

The relative maximum is a point on the graph where the function changes from increasing to decreasing.

So,

From the graph, there is only one point.

So only one relative maximum.

The relative minimum is a point on the graph where the function changes from decreasing to increasing.

So,

From the graph, there are two relative maximums.

The function has four linear factors

(x + 4), (x + 2), (x - 2), and (x - 6).

x = -4, x = -2, x = 2, and x = 6

Thus,

The statements that are true about the functions are:

The leading coefficient is positive.

It has two relative maximums

It has four linear factors.

One of the zeroes is x = 2.

A polynomial is a factor of another polynomial if when divided they have a remainder of zero. True or False.

Answers

Answer:

True

Step-by-step explanation:

The Factor theorem states that  for any polynomial f(x) if f(c)=0 then x-c is a factor of the polynomial f(x).

If any polynomial f(x) is divided by x-a and remainder is 0 that means f(a)= 0 .In other words we can say x-a is a factor of the polynomial f(x).So the statement :If a polynomial is divided by (x-a) and the remainder equals zero then (x -a) is a factor of the polynomial is True.

Mr. Flores opened an account with a deposit of $5,000.


• The account earned annual simple interest.

• He did not make any additional deposits or withdrawals.

• At the end of 4 years, the balance of the account was $6,500.


What is the annual interest rate on this account?

A. 5.8%

B. 7.5%

C. 3.3%

D. 1.9%

Answers

Answer:

B. 7.5%

Step-by-step explanation:

First, we need the Simple Interest (S.I)

Total = Principal + Simple Interest

T = P + S.I

6500 = 5000 + S.I

[make S.I the subject of the formula]

S.I = 6500 - 5000

S.I = 1500

Simple Interest = (Principal × Rate × Time) / 100

S.I = (P × R × T) / 100

1500 = (5000 × R × 4) / 100

1500 = 20000R / 100

1500 = 200R

[divide both sides of the equation by 200]

1500 / 200 = 200R / 200

R = 1500 / 200

R = 7.5

The annual interest rate is 7.5%

Mia is 7.01568 x 10^*6 minutes old. Convert her age to more appropriate units using years, months, and
days. Assume a year has 365 days and a month has 30 days.
Mia is
years=,
= months, and =
days old.

Answers

[tex]7.01568 * 10^6=7015680[/tex] minutes

There are:

60 minutes in an hour

24 hours in a day (60 * 24 = 1440 minutes)

30 days in a mouth (1440 * 30 = 43,200 minutes)

360 days in a year (1440* 365 = 525,600 minutes)

To find out how many years old she is we must divide the number of minutes old she is by the number of minutes in a year.

7015680 / 525,600 = 13 years with a remainder of 182,880 minutes

To find out how many months old she is we must divide the remaining minutes by the number of minutes in a month.

182,880 / 43,200  = 4 months with a remainder of 10,080 minutes

To find out how many days old she is we must divide the remaining minutes by the number of minutes in a day.

10,080 / 1440 = 7 days

The sum of two numbers is 50 and the difference is 4

Answers

Step-by-step explanation:

let the 2 numbers be x and x + 4 as their deference is 4.

their sum = 50

now,

x + x + 4 = 50

2x + 4 = 50

2x = 50 - 4 = 46

x = 46/2 = 23

therefore two numbers are,

x = 23

x + 4 = 23 + 4 = 27

hope this answer helps you dear...take care and may u have a great day ahead!

Step-by-step explanation:

x + y = 50

x - y = 4

x = y + 4

let's use that as substitute in the first equation

y + 4 + y = 50

2y = 46

y = 46/2 = 23

=>

x = y + 4 = 23 + 4 = 27

the 2 numbers are 23 and 27.
