Given the sequence.
125, 25, 5, ...
Write the rule an using the geometric sequence formula:

Answer:

(-3,0) and (0,-3)

Step-by-step explanation:

When you are looking for an intercept one of the coordinates is going to be 0.

The line or linear function which has a y-intercept at -3 will be that line that passes through (-3,0) and (0, -3).

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

F(x) = x is a line through the origin and is the parent linear function.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

A linear function has a single and unique constant slope.

In the given problem the line which intercepts y at -3 will be that line in which one y coordinate should be -3 since, it is coordinated with 0, -3)  hence, it will be the correct answer.

Answer:

Cylinder

explanation:

The formula for the volume of a cylinder is V=πr²h

To find the volume of a cylinder, the formula V = πr²h is used, where you multiply the square of the radius by π and then by the height, ensuring consistent units throughout.

To get the volume of a cylinder, you need to use the formula V = πr²h, where V stands for volume, π is a mathematical constant approximately equal to 3.14159, r represents the radius of the cylinder's base, and h denotes the height of the cylinder. To calculate the volume, first square the radius, then multiply that by π, and finally multiply by the cylinder's height. For example, if a cylinder has a radius of 0.750 cm and a height of 5.25 cm, you would calculate the volume as follows: 3.142 × (0.750 cm)2 × 5.25 cm, which equals approximately 9.278 cm3. Remember to use consistent units throughout the calculation.

Answer:

x=-17 and x=-19

Step-by-step explanation:

-17+18=1

-19+18=-1

|-1| =1

Answer:

-17 and -19

Step-by-step explanation:

Absolute value equations have two problems and two solutions unless the original answer equals a negative-then it would be no solution.

x + 18 =1 subtract 18 from both sides to get x by itself

x = 1-18

x= -17

x +18 = -1  subtract 18 from both sides to get x by itself

x= -1 -18

x= -19

Answer:

-6x+y=0

Step-by-step explanation:

y+6=-6(x+1)

y+6=-6x-6

-6x+y=0

On converting y + 6 = -6(x + 1) to Ax+By=C form, get 6x + y = -6 with A=6, B=1, and C=-6.

To rewrite the equation y + 6 = -6(x + 1) in the Ax+By=C form, where A, B, and C are integers, we need to distribute the -6 and then move all terms involving variables to one side of the equation and the constant term to the other side.

First, distribute the -6:

y + 6 = -6x - 6

Now, move the variable terms to one side by adding 6x to both sides:

6x + y + 6 = 0

Finally, subtract 6 from both sides to isolate the constant:

6x + y = -6

Now the equation is in the desired format with A=6, B=1, and C=-6.

Answer:

$594.75

Step-by-step explanation:

Given

yearly salary of Stephen= $41,236

No of weeks in a year = 52

Therefore, one week salary of Stephen = $41,236/52 = $793

to get one week salary divide total salary by number of weeks

5 weeks salary of Stephen = 5*793 = $ 3,965

agency fees = 15% of Stephen's 5 week salary

                      (15/100)*($ 3,965)  = $594.75

Therefore, Stephen has to pay $594.75 to the agency.

two and a half batches?

Final answer:

Pauline used 1 cup of sugar and each batch of cookies requires 2/5 cup. By dividing 1 cup by 2/5 cup, we get 2.5 giving us ≈2 batches.

Explanation:

The question asks how many batches of cookies Pauline was able to make if she used 1 cup of sugar, with each batch requiring 2/5 of a cup of sugar. To find this, we can use a simple division process as our conversion factor. You divide the total amount of sugar used by the amount needed per batch.

Steps to calculate the number of batches:

Pauline uses 2/5 of a cup of sugar for each batch of cookies.

She used a total of 1 cup of sugar yesterday.

To find the number of batches made, divide the total amount of sugar by the amount per batch: 1 cup / (2/5 cup per batch) = 5/2 = 2.5 batches.

However, since you cannot make half a batch of cookies, Pauline must have made 2 batches.

The values are x=8 and y=35, if the given ΔABC and ΔDEC are equal, it is obtained by Pythagoras theorem.

Step-by-step explanation:

The given are,

           From ΔABC,

                    AB= 6

                    BC= 10

                    AC = x

           From ΔDEC,

                    CD= 28

                    DE= 21

                    CE = y

Step:1

        Pythagoras theorem from  ΔABC,

                    [tex]BC^{2}=AB^{2} + AC^{2}[/tex]...............(1)

       Substitute the values,

                   [tex]10^{2}[/tex] = [tex]6^{2}[/tex] + [tex]AC^{2}[/tex]

                  100 = 36 + [tex]AC^{2}[/tex]

                   [tex]AC^{2}[/tex] = 100 - 36

                           = 64

                    AC = [tex]\sqrt{64}[/tex]

                    AC = 8

                  AC = x = 8

Step:2

        Pythagoras theorem for ΔDEC,

               [tex]CE^{2} = CD^{2} + DE^{2}[/tex]................(2)

       From the values,

              [tex]CE^{2}[/tex] = [tex]28^{2}[/tex] + [tex]21^{2}[/tex]

             [tex]CE^{2}[/tex] = 784 + 441

                     = 1225

              CE = [tex]\sqrt{1225}[/tex]

              CE = 35

             CE = y = 35

Result:

         The values are x=8 and y=35, if the given ΔABC and ΔDEC are equal.

To calculate the confidence interval for the mean age of cars in the commuter lot, we'll use the formula:

[tex]\[ \text{Confidence interval} = \bar{x} \pm t \left( \frac{s}{\sqrt{n}} \right) \][/tex]

where:

- [tex]\(\bar{x}\)[/tex] is the sample mean age (14.5 years),

- [tex]\(s\)[/tex] is the sample standard deviation (4.6 years),

- [tex]\(n\)[/tex] is the sample size (16),

- [tex]\(t\)[/tex] is the critical value from the t-distribution corresponding to the desired confidence level (90% in this case).

First, we need to find the critical value \(t\) for a 90% confidence level with [tex]\(n-1 = 15\)[/tex] degrees of freedom. Using a t-distribution table or calculator,[tex]\(t \approx 1.753\).[/tex]

Now, we can plug in the values:

[tex]\[ \text{Confidence interval} = 14.5 \pm 1.753 \left( \frac{4.6}{\sqrt{16}} \right) \][/tex]

[tex]\[ \text{Confidence interval} = 14.5 \pm 1.753 \times \frac{4.6}{4} \][/tex]

[tex]\[ \text{Confidence interval} = 14.5 \pm 1.753 \times 1.15 \][/tex]

[tex]\[ \text{Confidence interval} = 14.5 \pm 2.12595 \][/tex]

[tex]\[ \text{Confidence interval} = (12.37405, 16.62595) \][/tex]

Complete question:

Ignacio is curious about the average age of cars in the commuter lot at his large university. He takes a random sample of 16 cars and finds that their average age is [tex]$\bar{x}=14.5$[/tex] years and their standard deviation is [tex]$s_x=4.6$[/tex]years. The distribution of ages in the sample was roughly symmetric with no obvious outliers.

Based on this sample, which of the following is a [tex]$90 \%$[/tex] confidence interval for the mean age of cars (in years) in this commuter lot?

Choose 1 answer:

(A) [tex]$(6.44,22.56)$[/tex]

(B) [tex]$(12.05,16.95)$[/tex]

(c) [tex]$(12.48,16.52)$[/tex]

(D)[tex]$(12.61,16.39)$[/tex]

(E) [tex]$(13.35,15.65)$[/tex]

The 90% confidence interval for the mean age of cars in the commuter lot is (12.48, 16.52). The correct answer is: c) (12.48, 16.52)

Step 1

To determine the 90% confidence interval for the mean age of cars in the commuter lot, we can use the formula for the confidence interval of the mean for a normally distributed sample:

[tex]\[ \text{CI} = \bar{x} \pm t \left(\frac{s}{\sqrt{n}}\right) \][/tex]

Where:

- [tex]\(\bar{x}\)[/tex] is the sample mean (14.5 years)

- [tex]\(s\)[/tex] is the sample standard deviation (4.6 years)

- n is the sample size (16)

- t is the t-value for the 90% confidence level with [tex]\(n-1\)[/tex] degrees of freedom (df = 16 - 1 = 15)

First, we find the t-value for 90% confidence and 15 degrees of freedom. Using a t-table or a calculator, the t-value (two-tailed) is approximately 1.753.

Step 2

Next, we calculate the margin of error:

[tex]\[ \text{Margin of Error} = t \left(\frac{s}{\sqrt{n}}\right) = 1.753 \left(\frac{4.6}{\sqrt{16}}\right) = 1.753 \left(\frac{4.6}{4}\right) = 1.753 \times 1.15 \approx 2.016 \][/tex]

Now, we calculate the confidence interval:

[tex]\[ \text{CI} = 14.5 \pm 2.016 \][/tex]

So, the lower bound is:

[tex]\[ 14.5 - 2.016 = 12.484 \][/tex]

And the upper bound is:

[tex]\[ 14.5 + 2.016 = 16.516 \][/tex]

Thus, the 90% confidence interval for the mean age of cars is approximately:

[tex]\[ (12.48, 16.52) \][/tex]

This interval suggests that we are 90% confident that the true mean age of cars in the commuter lot lies between 12.48 and 16.52 years.
