Answer:

  [tex]f(x)=\left\{\begin{array}{cl}-x^2+11x-28&\text{for $4<x<7$}\\x^2-11x+28&\text{otherwise}\end{array}\right.[/tex]

Step-by-step explanation:

The absolute value function negates its contents when those contents are negative. Here, the quadratic factors as ...

 x^2 -11x +28 = (x -4)(x -7)

so will be negative when the factors have different signs. That will be the case for 4 < x < 7.

The piecewise function can be written in 3 parts, one part for x ≤ 4, another part for 4 < x < 7, and the remaining part for 7 ≤ x. The function expressions for x ≤ 4 and 7 ≤ x are identical.

In the answer above, we chose to write it with the part where the quadratic is negated being defined on the appropriate interval, and using "otherwise" for the rest of the function. It is a little unconventional to do it this way, but it is more compact and completely defines the function.

Use synthetic division to solve (x3 + 1) = (x - 1). What is the quotient?
o x2+x+1+12
O x2 - X+1
O x2+x+1+421
x - x² + x

Answers

Answer:

x² + x + 1 and remainder 2

Step-by-step explanation:

Given

(x³ + 1) ÷ (x - 1)

Without using a synthetic division, we can use easier method to find the quotient.

We know the formula:

x³ - 1 = (x - 1)(x² + x + 1)

Rewrite the given as:

x³ + 1 = x³ - 1 + 2 = (x - 1)(x² + x + 1) + 2

This expression, when divided by (x - 1) leave the quotient (x² + x + 1) and a remainder of 2

The quotient of the equation is A = x³ + x + 1 + ( 2/x + 1 )

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the first equation be p = x³ + 1

Let the second equation be q = x - 1

A = p / q

On simplifying , we get

A = x³ + 1 / ( x - 1 )

On dividing , we get the quotient as

A = x² + ( x² + 1 ) / ( x - 1 )

A = x³ + x + 1 + ( 2/x + 1 )

Hence , the quotient is A = x³ + x + 1 + ( 2/x + 1 )

You have hired a financial adviser to help you explore different loan options and decide which one is best for you. Below you will see the different loan options. You will need to calculate the total cost of each loan with interest. Once you have do this you and your group members will need to decide which of the loan options is best for you and why.

Option #1 – charges 5% simple interest per year; this is a short-term loan for only 5-years.






Option #2 – charges 7% simple interest per year; this is a short-term loan for only 3-years.








Option #3 – charges 3.2% simple interest per year; there is no time limit on this loan (as a group determine how long you think it will take you to make enough money to be able to pay back the loan with interest)

Step-by-step explanation:

Linear function:

Has the following format:

y = mx + b

In which m is the slope and b is the y-intercept.

In a linear function, when x changes by 1, y will always changes by the same amount.

Function A:

When x changes by 1, y can change by various amounts. So function A is non-linear.

A singles tennis court measures (8x – 2) ft long and (3x – 3) ft wide.Which expression represents the area of the court?

Answers

Answer:

The expression that represents the area of the court is: [tex]24x^2 - 30x + 6[/tex]

Step-by-step explanation:

Area of a rectangle:

A rectangle has length l and width w. The area of a rectangle is:

[tex]A = lw[/tex]

A singles tennis court measures (8x – 2) ft long and (3x – 3) ft wide.

This means that [tex]l = 8x - 2, w = 3x - 3[/tex]

Which expression represents the area of the court?

The tennis court is rectangular, so

[tex]A = lw = (8x - 2)(3x - 3) = 24x^2 - 24x - 6x + 6 = 24x^2 - 30x + 6[/tex]

The expression that represents the area of the court is: [tex]24x^2 - 30x + 6[/tex]

What is 0.63 divided by 0.18

Answers

Answer:

The answer is 3.5. I have included a screenshot that shows the work and how to get 3.5. I hope this helps!

And by the way yes, I do know this is a kinda old question, but I would like points and I have the answer.

:D

- Your friendly (a little bit late) responder!

When you divide 0.63 by 0.18, you get the result of 3.5.

To find the result of dividing 0.63 by 0.18, perform the division as follows:

0.63 ÷ 0.18 = 3.5

When you divide 0.63 by 0.18, the result is 3.5. This means that there are 3.5 sets of 0.18 in 0.63. To verify this, you can multiply 0.18 by 3.5:

0.18 × 3.5 = 0.63

So, 0.63 divided by 0.18 equals 3.5.

Roger has two golden retrievers, Sadie and Buddy. buddy weighs 14 pounds more than Sadie. If their total weight is 136 pounds, how much does Sadie weigh

Answers

Answer:

Sadie weighs 61 pounds.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

Sadie's weight is x.

Buddy's weight is y.

Buddy weighs 14 pounds more than Sadie.

This means that [tex]y = x + 14[/tex]

Their total weight is 136 pounds.

This means that

[tex]x + y = 136[/tex]

Since [tex]y = x + 14[/tex]

[tex]x + x + 14 = 136[/tex]

[tex]2x = 122[/tex]

[tex]x = \frac{122}{2}[/tex]

[tex]x = 61[/tex]

Sadie weighs 61 pounds.

What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) component, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                                   Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables. Equations with variables of power 1 are referred to be linear equations. One example with only one variable is where ax+b = 0, where a and b are real values and x is the variable.

equation 42 ÷ k = 14

              42/k = 14

                42 = 14 * k

                 k = 42/14

9. When Diego's phone is fully charged, it will last 18 hours. How much time 1 point

is left on his phone when the battery has 15% charge remaining? *

Answers

Answer:

2.7 hours

Step-by-step explanation:

Assuming that each percentage is worth the same amount of time. Then we can use the Rule of three since this is a ratio problem and we are given three values and a variable which is the amount of time that the battery lasts at 15%. This variable is represented by the letter x. To solve this we simply multiply the diagonal values and divide by the last remaining value which gives us the value of the variable like so...

100%  <====>  18 hours

 15%   <====>  x hours

(15 * 18) / 100 = 2.7 hours

Finally, we can see that 15% charge on the phone will last 2.7 hours
