A circle has a diameter of 12mm . what is its circumference? use 3.14 for π , and do not round your answer. be sure to include the correct unit in your answer.

Answers

Answer 1
c=πd therefore the answer is 37.68 mm
Answer 2

With a diameter of 12mm and using π as 3.14, the circumference is calculated as 37.68mm.

The circumference of a circle can be calculated using the formula:

Circumference = π x diameter

Given: Diameter = 12mm

Using π = 3.14:

Circumference = 3.14 x 12mm = 37.68mm

Therefore, the circumference of the circle is 37.68mm.

Answers

Just add 0.2 to 3.0 and the number after:

3.0, 3.2, 3.4, 3.6, 3.8

Hope I helped :)

Answer:

Decimals between 3.0 and 3.8 with an interval of 0.2 between each pair of decimals are:

3.2,3.4 and 3.6

Step-by-step explanation:

We have to find decimals between 3.0 and 3.8 with an interval of 0.2 between each pair of decimals

3.0

3.0+0.2= 3.2

3.2+0.2= 3.4

3.4+0.2= 3.6

3.6+0.2= 3.8

Hence, decimals between 3.0 and 3.8 with an interval of 0.2 between each pair of decimals are:

3.2,3.4 and 3.6

Which equation is the inverse of y = x2 – 36?

Answers

its B.y=±√​n+36​​​       

i hope that helps 

Answer:

The given equation of the curve is

 y= x² - 36

To find it's inverse we have to convert y in terms of x.

So, adding 36 to both sides of equation

→ y + 36=x² -36 + 36

→ y + 36 = x²

→ x² = y+ 36

→ x =[tex]\pm[/tex][tex]\sqrt{y+36}[/tex]

Now, to find inverse you can replace x by y, so by replacing x by y, the above equation becomes

y =[tex]\pm\sqrt{x+36}[/tex]

Second option is correct.

A scatterplot is produced to compare the size of a lake to the number of fish that are in it. There are 15 data points, each representing a different lake. The points are widely dispersed on the scatterplot with no pattern of grouping. Interpret what the results of the scatterplot tell you about the relationship between the two variables.

Answers

There is no direct relationship between the size of a lake and number of fish in it. There are other factors than size which determine how many fish may be present in the lake.

Answer:Since there is no cluster formed in the scatterplot, the two variables are not related. Therefore, based on the data shown in the scatterplot, the number of fish in a lake is not dependent on the size of the lake.

If you travel 156 miles on 4 gallons of gasoline how far can you travel on 12 gallons how many miles on 6 gallons

Answers

6 gallons should be 234 miles and 12 should be 468

You can travel a distance of 468 miles on 12 gallons of gasoline and a distance of 234 miles on 6 gallons of gasoline.

What is Proportion?

Proportion is the setting of two or more ratios to be equal.

That is, if there is a ratio between a and b and another ratio between c and d, then we can say that,

a : b = c : d ⇒ a/b = c/d ⇒ a d = b c

We have,

Distance travelled is 156 miles on 4 gallons of gasoline.

We have to find the distance travelled on 12 gallons and 6 gallons of gasoline.

Let x be the distance travelled on 12 gallons of gasoline and y be the distance travelled on 6 gallons of  gasoline.

We have a proportional relation here,

156 : 4 = x : 12 = y : 6

First taking the relation,

156 : 4 = x : 12

⇒ 156/4 = x/12

⇒ 39 = x/12

⇒ x = 39 × 12

⇒ x = 468

Taking the second relation,

156 : 4 = y : 6

⇒ 156/4 = y/6

⇒ 39 = y/6

⇒ y = 39 × 6

⇒ y = 234

Hence you can travel 468 miles on 12 gallons and 234 miles on 6 gallons.

2. Consider the function . a.) Find the inverse of f(x) and name it g(x). Show and explain your work. b.) Use composition to show that f(x) and g(x) are inverses of each other. c.) Draw the graphs of f(x) and g(x) on the same coordinate plane. Explain what about your graph shows that the functions are inverses of each other.

First correct answer will get 25 pts and brainliest!!!! So please help! :D

Answers

Part A:

Given that [tex]f(x)= \frac{1}{3} x+2[/tex], we find the inverse g(x) as follows:

First, we rewrite the function as: [tex]y=\frac{1}{3} x+2[/tex]

Next, we switch x and y and then solve for y as follows:

[tex]x=\frac{1}{3} y+2 \\ \\ \frac{1}{3} y=x-2 \\ \\ y=3(x-2) \\ \\ y=3x-6[/tex]

We then rewrite the equation using function notation to get:

[tex]g(x)=3x-6[/tex]



Part B:

For two function that are inverse of each other, the composition of the two functions gives x.

Thus,

[tex]f \circ g=f(g(x))=f(3x-6)= \frac{1}{3} (3x-6)+2=x-2+2=x \\ \\ g\circ f=g(f(x))=g( \frac{1}{3} x+2)=3( \frac{1}{3} x+2)-6=x+6-6=x \\ \\ \therefore f\circ g=g\circ f=x[/tex]

Since, f o g = g o f = x, hence g(x) is the inverse of f(x).



Part C:

The graphs of f(x) and g(x) are attached.

From the graph it can be seen that the prperties of both graphs are similar, the properties of one graph in the x-axis correspond to the properties of the other graph in the y-axis and vice-versa. Also, the two lines intersect at a point were x = y.

If (1, 2) and (3, 4) lie on the same line, give the slope-intercept equation of the line.

Answers

The slope of the line is  (4-2) / (3-1) = 2/2 = 1 
y - y1 = x - x1 
here x1 = 1 and y1 = 2 :-
y - 2 = x - 1
y = x + 1 <---- Answer

Final answer:

The slope-intercept equation of the line that passes through (1, 2) and (3, 4) is y = x + 1, with a slope of 1 and a y-intercept of 1.

Explanation:

To find the slope-intercept equation of a line that passes through the points (1, 2) and (3, 4), we first need to determine the slope of the line. We use the formula for the slope (m) given by the change in y over the change in x, or Δy/Δx. Calculating the slope, we get:

m = (4 - 2) / (3 - 1) = 2 / 2 = 1.

Now we have the slope, we can use the slope-intercept form of the line, which is y = mx + b, where m is the slope and b is the y-intercept. Plugging in one of the points, say (1, 2), into this equation gives us:

2 = (1)(1) + b

Which simplifies to:

b = 2 - 1 = 1

So the y-intercept (b) is 1. Therefore, the slope-intercept equation of the line is:

y = x + 1

In a company, it takes 4 employees 4 days to complete a task. It would take 2 employees 8 days to complete the same task. Which function can be used to represent e, the number of employees working on the task, and d, the number of days it takes them to complete that task?

Answers

The function representing the relationship between the number of employees and the number of days it takes to complete the task is[tex]\[ e \times d = 16 \][/tex].

To represent the relationship between the number of employees (e) and the number of days (d) it takes to complete a task, we can use the formula:

[tex]\[ e \times d = k \][/tex]

where  k is a constant representing the amount of work to be done.

Given the information that 4 employees complete the task in 4 days, and 2 employees complete it in 8 days, we can set up two equations using the formula:

[tex]\[ 4 \times 4 = k \][/tex]

[tex]\[ 2 \times 8 = k \][/tex]

Now, solve each equation for ( k):

[tex]\[ 4 \times 4 = 16 \][/tex]

[tex]\[ 2 \times 8 = 16 \][/tex]

Since both equations give us the same constant ( k ), we can conclude that:

[tex]\[ e \times d = 16 \][/tex]

Therefore, the function representing the relationship between the number of employees and the number of days it takes to complete the task is:

[tex]\[ e \times d = 16 \][/tex]

Step-by-step explanation:

The given inequality is  x+3y ≥ −8

Substitute all the given points in this inequality and check which points satisfy.

For (−6, 0)

-6+3(0) ≥ −8

- 6 + 0  ≥ −8

- 6 ≥ −8   => True.

Hence, (−6, 0) is a solution.

For (−1, −2)

-1 + 3(-2) ≥ −8

-1 - 6 ≥ −8

- 7 ≥ −8 => True.

Hence, (−1, −2) is a solution.

For (−5, −1)

-5 + 3 (-1) ≥ −8

- 5 -3  ≥ −8

-8 ≥ −8=> True.

Hence, (−5, −1) is a solution.

For (−16, 2)

-16 +3 (2) ≥ −8

-16 + 6 ≥ −8

-10≥ −8 => False.

Hence,(−16, 2) is not a solution.

For (0, -3)

0 + 3(-3) ≥ −8

-9  ≥ −8=> False.

Hence, (0, -3) is not a solution.

Therefore, below ordered pairs are solutions of the given inequality

(−6, 0) , (−1, −2)  and (−5, −1)
