 Polynomial equations are those created using exponents, coefficients, and variables. It may have several exponents, with the higher one being referred to as the equation's degree.

Polynomial equation illustration

     Write a polynomial equation in standard form before attempting to solve it. Factor it, then set each variable factor to zero after it has reached zero. The original equations' answers are the solutions to the derived equations. Factoring cannot always be used to solve polynomial equations.

This is a problem based on permutations. We must select four jobs among ten jobs and see how many arrangments can be made.

The formula for the number of permutations is:

Where:

• n = total number of jobs = 10,

• r = number of jobs to be selected = 4.

Replacing these data in the formula above, we get:

First, remember that:

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this problem, notice that:

2 + 3 is not greater than 5.

3 + 5 is not greater than 2.

2 + 5 is not greater than 3.

So, the statement is false. A triangle can't have sides 2

The values of the functions are:

1. f(2/3) = 2/9

2. f(1/4) = -21/4

If we are given the a function to find the value for which x assumes a given value, substitute the given value of x into the function and solve.

1. To find the value of f(2/3), substitute x = 2/3 into the function f(x) = 2x² - 4x + 2.

f(2/3) = 2(2/3)² - 4(2/3) + 2

f(2/3) = 2(4/9) - 8/3 + 2

f(2/3) = 8/9 - 8/3 + 2

f(2/3) = (8 - 24 + 18)/9

f(2/3) = 2/9

2. To find the value of f(1/4), substitute x = 1/4 into the function f(x) = 4x² + 2x - 6.

f(1/4) = 4(1/4)² + 2(1/4) - 6

f(1/4) = 4(1/16) + 1/2 - 6

f(1/4) = 1/4 + 1/2 - 6

f(1/4) = (1 + 2 - 24)/4

f(1/4) = -21/4

Answer:b

Step-by-step explanation:

b. You have to consider year 2000 as the initial year, i.e. as x=0.

To predict the percent of adults with diabetes in 2014, first, you have to calculate the difference between this year and the initial year to determine which value of x you need to use:

The value of x you have to use is x=14

Replace this value into the linear model calculated in item a to predict the percentage of adults with diabetes (y)

In the year 2014, the predicted percentage of adults with diabetes is 17.8%

c. You have to determine the year in which the model predicts the percent to be 27.96%.

To determine this year, you have to equal the linear model to 27.96% and calculate for x:

-Subtract 10.692 from both sides of the equal sign

-Divide both sides by 0.508

Next, add x=34 to the initial year:

The model predicts the percentage to be 27.96% for the year 2034

The height of the ball was 182.25 feet and it took 6 seconds for the ball to hot the ground.

Given that:-

Quadratic equation:-

[tex]h(t)=-16t^2+84t+72[/tex]

We have to find the ball's height, in feet and how many seconds it takes to hit the ground.

Differentiating the given equation, we get

dh/dt=-32t + 84

Putting dh/dt = 0, we get,

-32t + 84 = 0

t = 84/32 = 21/8 seconds

Putting t = 21/8, we will get the maximum height that the ball will reach.

Hence,

[tex]h(21/8)=-16(21/8)^2+84(21/8)+72[/tex]

h(21/8) = -16(441/64)+84(21/8)+72 = -110.25 + 220.50 +72 = 182.25 feet

At h = 0, the ball will have hit the ground.

Hence, we can write,

[tex]h(t) = 0 = -16t^2+84t+72[/tex]

Dividing -4 from the equation, we get,

[tex]4t^2-21t-18=0[/tex]

Using middle term split theorem, we can write,

[tex]4t^2-24t+3t-18=0\\[/tex]

4t(t-6)+3(t-6) = 0

(t-6)(4t+3) = 0

Hence, the values of t can be:-

t = 6, -3/4

As the time cannot be negative, hence the ball will hit the ground after 6 seconds.

We are given the information that Bailey reads 2 and a half books in 3 and a third weeks.

2 and a half books can be seen as 5/2 books, just as follows

On the other hand, 3 and a third weeks can be seen as 10/ weeks, just as follows:

Next, we just have to use a rule of three, its as follows: "if Bailey read 5/ books in 10/3 weeks, how many books does she reads per week?"

With that, we proceed with the division:

That means that Bailey reads 3/4 books per week

Zale's percent mark up is 37.5 percent.

Mark up percentage is calculated by dividing the gross profit of a unit by the cost of that unit.

In other words, Mark-up percentage is the difference between a product's selling price and cost as a percentage of the cost.

Therefore, Zale's sells diamonds for $1,100 that cost $800.

Hence,

mark up = 1100 - 800

mark up = $300

percentage mark up = 300 / 800 × 100

percentage mark up = 30000 / 800

Therefore,

percentage mark up = 37.5%

The given system of equations are

y=-3x/2 + 6

y=5x - 7

We would substitute values for x into the equations and find the corresponding y values. These values would be plotted on a graph. Where the lines of both equations meet would represent the solution of the system of equations.

For the first equation,

y = - 3x/2 + 6

if x = 0, y = 3 * 0/2 + 6 = 6

If x = 1, y = - 3 * 1/2 + 6 = 4.5

if x = 2, y = - 3 * 2/2 + 6 = 3

We would plot these values on the graph

For the second equation,

y = 5x - 7

if x = 0, y = 5 * 0 - 7 = - 7

If x = 1, y = 5 * 1 - 7 = - 2

if x = 2, y = 5 * 2 - 7 = 3

We would plot these values on the graph

The diagram of the graph is shown below

Looking at the graph, at the point where both lines meet,

x = 2, y = 3

Thus, the solution is (2,3)

Given:

a. The amount of flour that the bakery used this month was a 50% increase relative to last month.

So, we will draw a diagram that represents the situation

As shown, for last month, we have drawn a rectangle divided into two equal areas, each one represents 50%

this month was a 50% increase, so, we have drawn 3 areas which represent 50% increase

b. The amount of milk that the bakery used this month was a 75% decrease relative to last month.

As shown, for last month, we have drawn a rectangle with four equal areas

75% decrease, so, we have to remove 3 areas to make the remaining = 25%

So, the difference will give a 75% decrease

We need to calculate 1/5 + 1/2:

H = 1/5 + 1/2

Then: H = 7/10

Problem

Solution

We have the following sequence of terms 34,25,16,7,....

Part a

The common difference for this case would be:

25-34= -9

16-25=-9

7-16= -9

Then the answer for part a would be -9

Part b

We want to write the following form:

an = a1 + (n-1) d

For this case d=-9, a1= 34

And then we can write the genral expression like this:

an = 34 + (n-1 ) (-9)

With n = 1,2,3,4....

Part c

In order to find the 20 th term we can replace n =20 and we got:

a20= 34 + (20-1) (-9) = 34-171= -137

Solve the expression,

We have that a loaf of sandwich bread contains 24 slices, then we have that the ratio must be constant between the loaves and the slices. If we have 1 loaf: 24 slices, this ratio must be equal in the table.

Therefore, we have that the only table that follows this is the table that has:

If we have:

2/48 = 1/24

3/72 = 1/24

4/96 = 1/24

The ratio of loaves to slices is the same, that is, 1 / 24.

What is mean by Simple interest?

The simple interest is defined as;

Simple interest = P r t

Where, P is principal amount.

r is rate and t is time period.

Given that;

Student take 2 loans for pay the college.

One loan at 8% interest and the other at 9% interest.

And, The total borrowed amount = $3,500

and, The interest loan = $294

Let The first amount of loan = x

And, The other amount of loan = y

So, We can formulate;

x + y = $3,500  ..... (i)

And, The interest loan = $294

So, We can formulate;

8x/100 + 9y/100 = $294  

8x + 9y = 29400  ... (ii)

Solve equation (i) and (ii) , we get;

Multiply by 8 in equation (i) and subtract from (ii), we get;

y = $1400

Hence,

x + y = $3,500

x + 1400 = 3500

x = 3500 - 1400

x = $2,100

Therefore, The amount of each loan are $2,100 and $1,400.
