Find the equation of the line in
slope Intercept form if the
line passes through the
points (-5, -1) and (-4, -1)

Answer:

The width is 3 ft

The length is  12 ft

Step-by-step explanation:

Let w = width

l = 4w

A = l*w

Replace length with 4w

A = 4w*w

36 = 4 w^2

Divide each side by 4

36/4 = 4w^2/4

9 = w^2

Take the square root of each side

sqrt(9) = sqrt(w)

3 =w

The width is 3 ft

The length is 4*3 = 12 ft

Answer:

a

A sample survey; we want to gather information about a population based on a sample.

b

An experiment; we want to establish a cause-and-effect relationship

c

An observational study; there is no particular population from which we will sample, we simply observe.

Step-by-step explanation:

Considering the first question

  Are people generally satisfied with how things are going in the country right now?

Here the aim is to gather the opinion of the entire population and since it is impossible to ask each and everyone that make up the population then the best option is to taken a sample of the population and then draw conclusion from their opinion

So the correct option to question a  is  

A sample survey; we want to gather information about a population based on a sample

Considering the second question

Do college students learn basic accounting better in a classroom or using an online course?

Here in other to get the best answer to the question there is need to carry out  a statistical experiment using a group of college student where by a particular group of college student is exposed to learning a particular topic through class room and another group of college student is exposed to learning the same subject through online and then the same test is given to both group of student to determine the outcome of the experiment.

So the solution to the question b is

 An experiment; we want to establish a cause-and-effect relationship

Considering the third  question

How long do your teachers wait on the average after they ask their class a question?  

For the above  question we see that in order to get the correct solution to this problem there is a need to observe the teachers during question and answer section of their teaching so the correct answer to this question is

An observational study; there is no particular population from which we will sample, we simply observe.

Answer:

The length of one lap of the track would be about 377 feet

Step-by-step explanation:

∵ A circular race track has a diameter of 120 feet

→ That means the length of each lap equal the circumference of the track

∴ The length of one lap = C

∵ The diameter of the track is 120 feet

∴ d = 120 feet

∵ C = πd

∴ C = π(120)

→ Use π = 3.141

∴ C = (3.141)(120)

∴ C = 376.92 feet

→ Round it to the nearest whole number

∴ C ≅ 377 feet

∴ The length of one lap of the track would be about 377 feet

Answer:

She will pay $7,500 interest over the 5 years

She will have to pay back $17,500 in total

Step-by-step explanation:

Let us revise the rule of the simple interest

I = Prt and A = P(1 + rt) , where:

∵ Leah borrows £10,000 over 5 years at a simple interest rate of 15%.

∴ P = 10,000

∴ t = 5

∴ r = 15% = [tex]\frac{15}{100}[/tex] = 0.15

→ Substitute them in the first rule to find the interest

∵ I = 10,000(0.15)(5)

∴ I = 7,500

∴ She will pay $7,500 interest over the 5 years

→ Let us find A

∵ A = 10,000(1 + 0.15×5)

∴ A = 17,500

∴ She will have to pay back $17,500 in total

Hello,

As you have not provided the graph, I can teach you how to answer the question.

You are solving for the slope of the line. The slope can be found by using the following equation:

slope (signified by the variable m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Note that the numbers does not exactly matter, only that what you set as variable [tex]x_1[/tex], the y inside that coordinate will also be [tex]y_1[/tex], and likewise for point 2.

For example, let us say your points for your line is (3 , 6) and (10 , 4)

Let:

[tex](x_1 , y_1)[/tex] [tex]= ( 3 , 6)[/tex]

[tex](x_2 , y_2) = (10 , 4)[/tex]

Plug in the corresponding numbers to the corresponding variables:

slope [tex]m = \frac{4 - 6}{10 - 3} = - \frac{2}{7}[/tex]

The given points will result in a [tex]-\frac{2 }{7}[/tex] slope.

Hope this helps!

Answer:

The function is:

f(x) = x^3 - 4*x^2 - 3*x + 18.

Below, you can see the graph of the function.

The statements that are true are:

As x increases from negative infinity to positive infinity, the y-values increase, decrease, and then increase again.

You can see this in the graph and may be really hard to see it without the graph, the easier way would be to see the derivate of f(x) and see that is first positive, then negative, and then positive.

f'(x) = 3*x^2 - 8*x - 3

As the leading coefficient is positive, the arms oppen up, and f'(0) = -3

Then is easy to see that from left to right, is positive, then negative, and then positive again.

The domain and range of the function are the set of real numbers.

For the domain, we do not have any denominator nor weird function that has problems in a particular value, so the domain is the set of all real numbers.

And as you can see, as the leading coefficient is an odd power of x, the range will go from minus infinity to infinity (you can also see it in the graph).

The function has a double root.

Yes, in the graph you can see two roots, but this is a 3rd-degree polynomial, so it must have 3 roots, this means that one of the roots in the graph is a double root. (Where the double root is at x = 3, as you can see in the graph)

Answer:

[tex]d = 9.2[/tex]

Step-by-step explanation:

Given

Points: (-2,-2) and (0,7)

Required

Determine the distance between them.

Distance is calculated as thus:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Where:

[tex](x_1,y_1) = (-2,-2)[/tex]

[tex](x_2,y_2) = (0,7)[/tex]

So, we have:

[tex]d = \sqrt{(0 - (-2))^2 + (7 - (-2))^2}[/tex]

[tex]d = \sqrt{(0 +2)^2 + (7 +2)^2}[/tex]

[tex]d = \sqrt{2^2 + 9^2}[/tex]

[tex]d = \sqrt{4 + 81}[/tex]

[tex]d = \sqrt{85}[/tex]

[tex]d = 9.2[/tex] --- Approximated

Answer:

Well, the correct answer is 119.4347826086956521739130 (after the 130 the whole decimal is repeated.

Step-by-step explanation:

Although if your assignment is asking for an estimate you could probably just say 119 since the first and second decimal is less then 5

The estimation of the expression 8.2 × 6.7 divided by 0.46 is approximately 112.

It is a rough calculation of the value, number, quantity, etc. It doesn't use real calculation but estimation by some method like prediction, using approximation etc.

For this case, we've to esimate the value of the expression:

[tex]E = \dfrac{8.2 \times 6.7}{0.46}[/tex]

Instead of using exact values, let we use:

[tex]8.2 \approx 8\\6.7 \approx 7\\0.46 \approx 0.5 = 1/2[/tex]

Then, we get:

[tex]E = \dfrac{8.2 \times 6.7}{0.46} \approx \dfrac{8 \times 7}{1/2} = 2 \times 8 \times 7= 2 \times 56 = 112[/tex]

Thus, the estimation of the expression 8.2 × 6.7 divided by 0.46 is approximately 112.

Answer:

The statements are not provided, so let's do a complete description of f(x)

In the graph, we can see two asymptotes at x = 1.

This means that the denominator is equal to 0 when x = 1, then we can write:

f(x) = A/(x - 1)

Where we can start thinking that A is a constant.

Now we also can see that when x = 2, f(2) is equal to 1, or:

f(2) = 1.

Then:

f(2) = 1   = A/(2 - 1) = A/1

Then we have  A = 1.

Then our function is:

f(x) = 1/(x - 1)

Answer:

the function would look like: f(x)=(x³+3)-1

the graph would literally look like the cubic parent graph, just shifted 3 left and 1 down

Answer: 819,000

Step-by-step explanation:

182000×9=1638000÷2=819000

Lisa's friend must pay Lisa $819,000 to become her partner in the business, half the worth of Lisa's business today.

The worth of an object is the price of that object currently. The worth of almost every object in this world is variable (not fixed) with time and use.

In the question, we are said that ten years ago, Lisa bought a hair salon for $182,000. Her business is now worth nine times what she paid.

∴ Worth of the business 10 years ago = $182,000.

Worth of the business now = 9*$182,000 = $1,638,000

We have been informed that Lisa has decided to sell half of her business to a friend. We are asked to find the amount her friend needs to pay, to become her partner.

As we have been told, she is selling half of her business, her friend will need to pay half of her business' worth at the present date.

∴ Her friend pays the amount = 1/2 * worth of the business now

or, Her friend pays the amount = 1/2 * $1,638,000

or, Her friend pays the amount = $819,000.

∴ Lisa's friend must pay Lisa $819,000 to become her partner in the business, half the worth of Lisa's business today.
