Do not post random subjects in mathematics.

Also, pain is temporary.

If you end your life you just pass it onto someone else.

Try to find people online that understand you. The reason why you can't do anything is because you keep telling yourself that. This sounds cringe but try new things and venture. Try meditation or yoga. If you aren't an open person then you can do breathing exercises in private. While you take in your breath think positively. I hope this advice can help you! Never give up!

Answer: y=-3x-16

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is slope and b is y-intercept.

y-2=-3(x+6)        [distribute]

y-2=-3x-18          [add both sides by 2]

y=-3x-16

Now, we see that the equation above matches the slope-intercept form equation. You can see that m=-3 and b=-16.

Answer:

The area of the shelf is 86.59 square inches

Step-by-step explanation:

The formula of the area of the circle is A = π r², where

∵ The corner shelf is [tex]\frac{1}{4}[/tex] of a circle

→ That means its area is [tex]\frac{1}{4}[/tex] the area of the circle

∴ The area of the corner shelf = [tex]\frac{1}{4}[/tex] × area of the circle

∵ Area of the circle = π r²

∴ The area of the corner shelf = [tex]\frac{1}{4}[/tex] × π r²

∵ The radius of the shelf is 10.5 inches

∴ r = 10.5 inches

→ Substitute the values of r in the formula of the area

∴ The area of the corner shelf = [tex]\frac{1}{4}[/tex] × π × (10.5)²

∴ The area of the corner shelf = 86.59014751

→ Round it to the nearest hundredth

∴ The area of the corner shelf = 86.59 square inches

∴ The area of the shelf is 86.59 square inches

Answer:

a. The answers obtained are as follows:

Frequency for flossing 7 times per week = 24

Relative frequency for flossing 4 times per week = 0.1231

Cumulative Frequency at flossing 1 time per week = 22

b. The Cumulative Relative Frequency at flossing 7 time per week is 100%.

Step-by-step explanation:

Note: This question is not complete and the data in it are merged together. The complete question is therefore provided with the sorted data before answering the question. See the attached pdf file for the complete question.

The explanation to the answers is now provided as follows:

a. Complete the table (Use 4 decimal places when applicable)

Note: See part a of the attached excel for the complete table (answers are in bold red color)

Frequency is the rate at which something or an event occurs in a particular sample.

Since we already have frequency for others flossing times per week and we have 130 adults as the sample, the frequency for flossing 7 times per week is calculated by deducting the frequencies of others from 130 as follows:

Frequency for flossing 7 times per week = 130 – 10 – 12 – 14 – 18 – 16 – 21 – 15 = 24

Relative Frequency refers to the fraction of times an event occurs. The relative frequencies in this question are calculated by dividing each frequency by the total number of adults in the sample, i.e. 130. The relative frequency for flossing 4 times per week is therefore calculated as follows:

Relative frequency for flossing 4 times per week = Frequency for flossing 4 times per week / Total number of adults in the sample = 16 / 130 = 0.1231

Cumulative Frequency is calculated by adding the current frequency to the previous Cumulative Frequency. The Cumulative Frequency at flossing 1 time per week is therefore calculated as follows:

Cumulative Frequency at flossing 1 time per week = Cumulative Frequency at flossing 0 time per week + Frequency at flossing 1 time per week = 10 + 12 = 22

b. What is the cumulative relative frequency for flossing 7 times per week? %

Note: See part b of the attached excel for the complete table (answer is in bold red color)

The cumulative relative frequency refers to the accumulation of the previous relative frequencies.

Cumulative Relative Frequency is calculated by adding the current relative frequency to the previous Cumulative Relative Frequency. It should be noted that the first cumulative relative frequency equal to the first relative frequency.

The Cumulative Relative Frequency at flossing 7 time per week is therefore calculated in the attached excel file as follows:

Cumulative Relative Frequency at flossing 1 time per week = Cumulative Relative Frequency at flossing 6 times per week + Relative Frequency at flossing 7 times per week = 0.8154 + 0.1846 = 1.0000

Since the question indicates that the Cumulative Relative Frequency at flossing 7 time per week should be stated in percentage term, we therrefore have:

Cumulative Relative Frequency at flossing 7 time per week = 1.0000 * 100 = 100%.

1. After solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]

2. After solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]

Step-by-step explanation:

We need to Solve the equations.

1.  [tex]10 - 6 x = 4 + 5 x[/tex]

Step 1: Subtract 5x on both sides

[tex]10 - 6 x-5x = 4 + 5 x-5x\\10-11x=4[/tex]

Step 2: Subtract 10 on both sides

[tex]10-11x-10=4-10\\-11x=-6[/tex]

Step 3: Divide both sides by -11

[tex]\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}[/tex]

So, after solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]

2. [tex]7-6x=1+5x[/tex]

Step 1: Subtract 5x on both sides

[tex]7 - 6 x-5x = 1 + 5 x-5x\\7-11x=1[/tex]

Step 2: Subtract 7 on both sides

[tex]7-11x-7=1-7\\-11x=-6[/tex]

Step 3: Divide both sides by -11

[tex]\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}[/tex]

So, after solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]

Answer:

1) Please find attached the diagram showing the answer to the question

The area of the diagram is (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares

∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2

2) When x = 1, (1 + 4)² = 25 ≠ 2 × 1² + 8 × 1 + 8 = 18

Therefore, (x + 4)² is not equivalent to 2·x² + 8·x + 8

Step-by-step explanation:

1) In the attached diagram, we have;

For x = 1

(3x + 1)(x + 2) = (3 + 1)(1 + 2)

Therefore, the length of the sides of the rectangle are;

Height = 4, and Width = 3

For x = 1, x² = 1² = 1

∴ 3·x² = 3, 7·x = 7 × 1 = 7, and 2 = 2

Therefore, from the diagram, we have;

The area = (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares

∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2

The diagram for when x = 3 is also included

2) For (x + 4)², we have;

When x = 1, (x + 4)² = (1 + 4)² = 25

However;

When x = 1, 2·x² + 8·x + 8 = 2 × 1² + 8 × 1 + 8 = 18

Therefore;

(x + 4)² is not equivalent to 2·x² + 8·x + 8

1) Please find attached the diagram showing the answer to the question

The area of the diagram is (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares

∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2

2) When x = 1, (1 + 4)² = 25 ≠ 2 × 1² + 8 × 1 + 8 = 18

Therefore, (x + 4)² is not equivalent to 2·x² + 8·x + 8

Step-by-step explanation:

1) In the attached diagram, we have;

For x = 1

(3x + 1)(x + 2) = (3 + 1)(1 + 2)

Therefore, the length of the sides of the rectangle are;

Height = 4, and Width = 3

For x = 1, x² = 1² = 1

∴ 3·x² = 3, 7·x = 7 × 1 = 7, and 2 = 2

Therefore, from the diagram, we have;

The area = (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares

∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2

The diagram for when x = 3 is also included

2) For (x + 4)², we have;

When x = 1, (x + 4)² = (1 + 4)² = 25

However;

When x = 1, 2·x² + 8·x + 8 = 2 × 1² + 8 × 1 + 8 = 18

Therefore;

(x + 4)² is not equivalent to 2·x² + 8·x + 8

Answer:

[tex]f(n) = 15 + (n + 1)[/tex]

Step-by-step explanation:

Tina earns $15 every week when she mows the lawn.

We would put $15 because she earns $15 every week.

She earns 15 every week, so we would put (n + 1).

Our final answer would be [tex]f(n) = 15 + (n + 1)[/tex]

Answer:

The explicit rule is:

[tex]f(n)=60+15(n-1)[/tex]

After 15 week, Tina will have $270 in her savings account.

Step-by-step explanation:

Let’s write down our sequence so we can see it better.

For the first week (i.e. the first term), Tina has $60.

For the second week (i.e. the second term), Tina has $75.

And for the 3rd, 4th, 5th, and 6th week, Tina has $90, $105, $120, and $135, respectively.

Therefore, we can write the following sequence:

60, 75, 90, 105, 120, 135...

Note that our initial term a is 60.

And our common diffference will be 15.

Let’s find the explicit rule. The standard format for an explicit rule is:

[tex]f(n)=a+d(n-1)[/tex]

Where a is the initial term and d is the common difference.

Let’s substitute 60 for a and 15 for d. Hence, our explicit formula is:

[tex]f(n)=60+15(n-1)[/tex]

So, to find the amount Tina will have in her savings account in 15 weeks, we will substitute 15 for n and evaluate. So:

[tex]f(15)=60+15(15-1)[/tex]

Evaluate:

[tex]\begin{aligned} f(15)&=60+15(14) \\ f(15)&=60+210 \\ f(15)&=270 \end{aligned}[/tex]

Hence, after 15 weeks, Tina would have $270 in her savings account.
