Jim spends 30 minutes writing 10 sentences (slowpoke!). If he has 30 more sentences to write and continues writing at this same rate, how long should it take him to finish the entire assignment? (I know the answer it's just that I want to see if anyone is going to reply...probably not)

Answer: second option.

Step-by-step explanation:

By definition, a function is even when:

[tex]f(x) = f(-x)[/tex]

Then, knowing this, given the function [tex]f(x)=x^3 +5x+1[/tex] you can substitute [tex]-x[/tex] into this function:

[tex]f(-x)=(-x)^3 +5(-x)+1[/tex]

Now you need to simplify the function. Then you get:

 [tex]f(-x)=-x^3 -5x+1[/tex]

In this case, you can see that:

 [tex]f(x)\neq f(-x)[/tex]

Therefore, the function [tex]f(x)=x^3 +5x+1[/tex] is not even.

As you observed in the procedure above, the statement that best describes how to determine whether the given function is even is:

Determine is [tex](-x)^3 +5(-x)+1[/tex] is equivalent to [tex]x^3 +5x+1[/tex]

Answer:

3

Step-by-step explanation:

Find the prime factorization of 81, which is 3 x 3 x 3 x 3. Next, do the same with 48, which is 2 x 2 x 2 x 2 x 3. Lastly, to find the gcf, multiply the prime factors that are common to both numbers. The GCF is 3

The required greatest common factor of 48 and 81 is 3.

To find the greatest common factor (GCF) of 48 and 81, we need to determine the largest number that evenly divides both 48 and 81.

We can start by listing the factors of each number:

Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

Factors of 81: 1, 3, 9, 27, 81

From the lists, we can see that the common factors of 48 and 81 are 1 and 3. However, we are looking for the greatest common factor, which in this case is 3.

Therefore, the greatest common factor of 48 and 81 is 3.

Answer:

-1 12⁄13

Step-by-step explanation:

-13x = 25 [Divide by -13]

x = -1 12⁄13

13 is your divisor, which will be your denominator, and the numerator is your remainder. Since 13 goes into 25 ONCE, 1 gets multiplied by 13 to get 13, then deduct that from 25 to get your remainder of 12. This is where you start putting the pieces together as a mixed number. Then attach the negative because whenever you divide a positive by a negative, you get a negative:

-25⁄13 = -1 12⁄13

When you find the measure of the intercepted arc, to find the measure of the angle/ divide the measure of the intercepted arc by 2, since the angle is on the circle and boom you get 90 degrees

Isolate “y” in one of the equations, then substitute it in the other equation. After you find x, put it in the isolated equation and you’ll find y value.

The value of x = 1 and y = 0.

Consider the given system of equation

4x - 2y = 4  ........(1)

6x - 4y = 6 ........(2)

Solve the system algebraically,

By using the elimination method,

Multiply equation (1) by 2, and we get,

(1) ⇒ 8x - 4y = 8 ............(3)

Subtract equation (2) from (3), we get,

8x - 4y - (6x - 4y) = 8 - 6

Simplifying the above equation, we get

8x - 4y - 6x + 4y = 2

8x - 6x = 2

⇒ x = 1

Substitute x = 1 in (1) and solve for y, we get,

⇒ 4x - 2y = 4

⇒ 4 (1) - 2y = 4

⇒ 2y = 4 - 4

⇒ 2y = 0

⇒ y = 0

Therefore, the value of x = 1 and y = 0.

b(2 ×10)+(3*1)+(0×1b)+(1×100)+(4×1000)

Final answer:

The number 23.014 in expanded form is (2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001), illustrating the value of each digit according to its place value.

Explanation:

Writing the number 23.014 in expanded form means expressing each digit according to its place value. Expanded form represents a number by showing the value of each digit. For the decimal number 23.014, we look at the place value of each digit: the digit in the tens place, the ones place, the tenths place (one place after the decimal), the hundredths place (two places after the decimal), and so on.

The correct expanded form for 23.014 is:
<(2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001)

This means:

The '2' is in the tens place, so it represents 2 x 10, or 20.

The '3' is in the ones place, so it represents 3 x 1, or 3.

The '0' is in the tenths place, but since it's 0, it adds no value (0 x 0.1 = 0).

The '1' is in the hundredths place, so it represents 1 x 0.01, or 0.01.

Finally, the '4' is in the thousandths place, so it represents 4 x 0.001, or 0.004.

Therefore, 23.014 written in expanded form is (2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001).

Answer:

The value of x is 2 or -2.

Step-by-step explanation:

Consider the provided equation.

[tex]3x^2= 12[/tex]

We need to solve the above equation for x.

Divide 3 from both the sides.

[tex]\frac{3x^2}{3}=\frac{12}{3}[/tex]

[tex]x^2=4[/tex]

Square root both the sides.

[tex]x=\pm \sqrt{4}[/tex]

[tex]x=\pm 2[/tex]

Hence the value of x is 2 or -2.

The solution to the equation  [tex]3x^2 = 12[/tex]  is [tex]x = \pm2[/tex], which is [tex]x = 2[/tex] and [tex]x = -2.[/tex]

To solve the equation [tex]3x^2 = 12[/tex] algebraically:

Divide both sides of the equation by 3 to isolate the [tex]x^2[/tex] term:

[tex]\frac{3x^2}{3}=\frac{12}{3}[/tex]

[tex]x^2 = 4[/tex]

Take the square root of both sides to solve for x:

[tex]\sqrt{x^2}=\sqrt{4}[/tex]

[tex]x = \pm2[/tex]

Hence, the solutions to the equation [tex]3x^2 = 12[/tex] are [tex]x = 2[/tex] and [tex]x = -2.[/tex]

Answer:

f(2) = 3

Step-by-step explanation:

We are given:

f(0) = 3

and

f(n+1) = -f(n) + 5

We have to find the value of f(2). In order to find f(2) we first have to find f(1)

f(n + 1) = - f(n) + 5

Using n = 0, we get:

f(0 + 1) = - f(0) + 5

f(1) = -f(0) + 5                                                     Using the value of f(0), we get

f(1) = -3 + 5 = 2

Now using n = 1 in the function, we get:

f(1 + 1) = - f(1) + 5                                               Using the value of f(1), we get

f(2) = -2+ 5

f(2) = 3

Answer:

A = 30m + 35

Step-by-step explanation:

let A be the amount saved and m represent month

Note the difference in the amount saved is constant, that is

185 - 155 = 155 - 125 = 125 - 95 = 95 - 65 = 30

We can express this as

A = 30m + c

To find c use any pair from the table and substitute into the equation

using (3, 125) then

125 = (3 × 30) + c

125 = 90 + c ( subtract 90 from both sides )

c = 125 - 90 = 35, thus

A = 30m + 35 ← linear relationship

As a check

When m = 4, A should be 155

A = (4 × 30) + 35 = 120 + 35 = 155 ← correct

Linear function representing the table is

A(m) = 30m + 35

This is a step function which is a type of function defined by two or more functions. To write the function, we can follow these steps:

STEP 1. A linear function.

This function goes from [tex]-\infty[/tex] to [tex]2[/tex] without including this last value in the domain because at [tex]x=2[/tex] we have a hole. By writing the equation:

[tex]The \ equation \ of \ the \ line \ with \ slope \ m \\ passing \ through \ the \ point \ (x_{1},y_{1}) \ is:\\ \\ y-y_{1}=m(x-x_{1})[/tex]

So:

[tex]P_{1}(1,0) \\ P_{2}(2,2) \\ \\ y-0=\frac{2-0}{2-1}(x-1) \\ \\ y=2(x-1) \therefore \boxed{y=2x-2}[/tex]

[tex]f(x)=2x-2, \ \ -\infty<x \leq 2[/tex]

STEP 2. Constant function.

This function goes from [tex]2[/tex] to [tex]5[/tex] including both values in the domain because at [tex]x=2[/tex] and at [tex]x=5[/tex] we have dots.

So:

[tex]f(x)=4, \ \ 2 \leq x \leq 5[/tex]

STEP 3. Linear function.

This is also a linear function but goes from [tex]5[/tex] to [tex]+\infty[/tex] without including [tex]x=5[/tex] in the domain because we have a hole here. By writing the equation:

So:

[tex]P_{1}(5,6) \\ P_{2}(6,7) \\ \\ y-6=\frac{7-6}{6-5}(x-5) \\ \\ y=x-5+6 \therefore \boxed{y=x-1}[/tex]

[tex]f(x)=x+1, \ \ 5<x \leq +\infty[/tex]

Finally, our step function is:

[tex]f(x)=\left\{ \begin{array}{c}2x-2,\;-\infty<x\leq2\\4,\;2\leq x\leq5\\x+1,\;5<x\leq+\infty\end{array}\right.[/tex]

The exponential regression equation for the data set is;

[tex]y=0.3258e^{0.1074x}[/tex]

Step-by-step explanation:

Exponential regression can easily be carried out in Ms. Excel. The first step is to enter the data in any two adjacent columns with the headers x and y in order to differentiate the response from the predictor variable.

The next step is to highlight the data, click the insert ribbon and choose the scatter-plot feature. This step will create an x, y scatter-plot for the data. The next step we click on the Add-Chart Element feature and add an exponential trend line to the scatter-plot while ensuring the Display Equation on chart is checked.

Ms. Excel provides the following exponential regression equation that models the data;

[tex]y=0.3258e^{0.1074x}[/tex]

Answer:

[tex]f'(-8)=\frac{9}{64}[/tex]

Step-by-step explanation:

Given the function

[tex]f(x)=\frac{-9}{x}[/tex]

We can rewrite it as

[tex]f(x)=-9x^{-1}[/tex]

Now we can apply the power rule

[tex]f'(x)=9x^{-2}[/tex]

Now we can rewrite it

[tex]f'(x)=\frac{9}{x^{2} }[/tex]

Now we can plug in x=-8

[tex]f'(-8)=\frac{9}{(-8)^{2} }\\f'(-8)=\frac{9}{64}[/tex]

The derivative of f(x) = -9/x at x = -8 is 9/64.

To find the derivative of f(x) = -9/x at x = -8, we can use the power rule for differentiation. The power rule states that if we have a function of the form f(x) = x^n, then the derivative of f(x) is given by f'(x) = n*x^(n-1).

In our case, the function is f(x) = -9/x. Rewriting it as f(x) = -9*x^(-1), we can apply the power rule and find that the derivative is f'(x) = (-1)*(-9)*x^(-1-1) = 9/x^2.

Substituting x = -8 into the derivative formula, we get f'(-8) = 9/(-8)^2 = 9/64.
