Answers
y + 5x = 0 is the line's equation in point-slope form.
Given is a line with a slope of 0 and a point at (0, -10) on it. We must determine the line's point slope form equation.
What shape does a line's point slope take?The line's point-slope shape is ( y -[tex]Y_{1}[/tex] ) = m ( x - [tex]X_{1}[/tex] ).
According to the query, slope (m) = 0 and
the line is going through ( [tex]X_{1}[/tex] , [tex]Y_{1}[/tex] ) = ( 0 , -10 )
∴ ( y - [tex]Y_{1}[/tex] ) = m ( x - [tex]X_{1}[/tex] )
y + 10 = 0 ( x - 0 )
y + 10 = 0
y + 5x = 0
As a result, the equation for the line in point-slope form will be
y + 5x = 0.

Answer: Choice A) [tex]\boldsymbol{78.67\% \ \pm \ 9.46\%}[/tex]
======================================================
Explanation:
phat = 59/75 = 0.7867 = 78.67% approximately is the sample proportion
n = 75 is the sample size
Your teacher doesn't mention a confidence level, so I'll assume it's the default 95%.
Let's compute the margin of error at 95% confidence
E = z*sqrt(phat*(1-phat)/n)
E = 1.96*sqrt(0.7867*(1-0.7867)/75)
E = 0.0927 approximately
E = 9.27% approximately
Unfortunately the margin of error 9.27% isn't listed among the four answer choices, but let's change the z = 1.96 to z = 2 instead.
Recalculate the margin of error.
E = z*sqrt(phat*(1-phat)/n)
E = 2*sqrt(0.7867*(1-0.7867)/75)
E = 0.0946 approximately
E = 9.46% approximately
This margin of error is listed among the four answer choices.
------------------
We found that
phat = 78.67% approximatelyE = 9.46% approximatelyThe confidence interval in the format [tex]\text{phat} \ \pm \ \text{E}[/tex] is approximately [tex]78.67\% \ \pm \ 9.46\%[/tex] which points us to choice A as the answer.
Answer:
[tex]\textsf{a)} \quad 78.67\% \pm 9.46\%[/tex]
or d) None of the answers are correct. (Please see notes below).
Step-by-step explanation:
P-hat is the probability that a given outcome will occur given a specified sample size.
[tex]\boxed{\begin{minipage}{7.5 cm}\underline{P-hat formula}\\\\$\hat{p}=\dfrac{X}{n}$\\\\where:\\\phantom{ww}$\bullet$ $\hat{p}$ is the probability. \\ \phantom{ww}$\bullet$ $X$ is the number of occurrences of an event. \\ \phantom{ww}$\bullet$ $n$ is the sample size.\\\end{minipage}}[/tex]
Given:
X = 59n = 75Substitute the given values into the formula to find p-hat:
[tex]\implies \hat{p}=\dfrac{59}{75} =0.78666666...[/tex]
The critical value for a 95% confidence level using normal distribution is:
[tex]z=1.9600\;\;\sf (4\;d.p.)[/tex]
[tex]\boxed{\begin{minipage}{5.2 cm}\underline{Margin of error}\\\\$ME=z \cdot \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$\\\\where:\\\phantom{ww}$\bullet$ $z$ is the critical value. \\ \phantom{ww}$\bullet$ $\hat{p}$ is the sample proportion. \\ \phantom{ww}$\bullet$ $n$ is the sample size.\\\end{minipage}}[/tex]
Substitute the given values into the margin of error formula:
[tex]\implies ME=1.9600 \cdot \sqrt{\dfrac{\dfrac{59}{75}\left(1-\dfrac{59}{75}\right)}{75}}[/tex]
[tex]\implies ME=0.092715036...[/tex]
Therefore, an estimate of the proportion of young-adult novels that include a love triangle (including a margin of error) is:
[tex]\implies \hat{p}\pm ME[/tex]
[tex]\implies 0.7867\pm 0.0927[/tex]
[tex]\implies 78.67\% \pm 9.27\%[/tex]
This result if not given in the list of answer options. However, the final result depends on the accuracy of the z-score and p-hat used in the calculations.
If we round the critical value to the nearest integer then:
[tex]\implies z=2[/tex]
Substitute the rounded z-value into the margin of error formula:
[tex]\implies ME=2\cdot \sqrt{\dfrac{\dfrac{59}{75}\left(1-\dfrac{59}{75}\right)}{75}}[/tex]
[tex]\implies ME=0.094607180...[/tex]
Therefore, an estimate of the proportion of young-adult novels that include a love triangle (including a margin of error) using z = 2 is:
[tex]\implies 78.67\% \pm 9.46\%[/tex]
Note: It is likely that this question required the critical value to be rounded to the nearest integer, however please note that this is not normal practice as it produces a different result, as evidenced above.

borrowing?
A. Debtors would less likely want to borrow.
B. There would be a government law against rising
interest rates.
C. There would be no impact on borrowing.
D. There would be an increase in borrowing.
Answers
Consequently, borrowing would increase with the change in interest rate from 10 % to 2 %. The correct answer is Option D.
What happens to interest rates when borrowing becomes more expensive?The greater the ability of banks to lend, the greater the amount of credit available to the economy. And as the supply of credit expands, so does the cost of borrowing (interest). The amount of credit available to the economy decreases as lenders decide to postpone loan repayment.What effect does a change in interest rates have on business borrowing?Higher interest rates make it more expensive for businesses to borrow money through loans and lines of credit, and they also affect how much interest you pay on credit card or home purchase purchases.
Given that the interest rate has risen from 10% to 2%.
Borrowers can easily borrow by paying less interest now that the interest rate has dropped from 10% to 2%.
As a result, borrowing would increase with the decrease in interest rates. Option D is thus correct.

The factored form of y = x² - x + 12 will be (x + 3)(x - 4).
What is factor?It should be noted that a factor simply means the number than can be multiplied by another number to get the original number. The factored form is when a quadratic expression is a product of two factors, each of which is a linear expression. By expanding, or multiplying out the factors, an equation in factored form can be restated in standard form.
This will be illustrated as:
x² - x - 12

Answers
1)
Consider P to be at the same vertical distance between the maximum and minimum height the blades can reach. Therefore, at t=0, P has to be at h=0 (the maximum height is 1 and the minimum one is -1).
Then, since the fan blades rotate counterclockwise, after t=0, h has to increase until it reaches a value of 1.
Finally, a revolution is completed after 1 second; therefore, at t=1, the h has to be equal to 0 (the same height as at t=0).
Thus, the graph that models the function is option D.2)
Approximately, every year the Earth reaches its maximum distance from the sun and its minimum distance once a year, and that is a cycle that repeats almost without alteration. Furthermore, since the position of the Earth around the sun is given by an ellipse, the position of the Earth around the Sun can be expressed using trigonometric functions (because of polar coordinates).
Similarly, a rotating wheel will reach its maximum and minimum height eventually; therefore, it can be modeled using trigonometric functions which are periodic.
Finally, as for the area of a sheet of paper. Notice that the more we fold it, the less its area becomes, it does not reach its maximum anymore.
Given x inches, the number of centimeters is 2.54x, this is not a periodic function.
Due to the effects of gravity, the height of a pendulum can be expressed using a periodic function given that no energy is lost.
The trajectory of a tossed ball is given by a parabola, unless one tosses the ball again at the same initial height, option F cannot be modeled using a periodic function.

Answers
The function rule of the scenario is f(x) = 15 + 8x
How to determine the function rule?From the question, the given parameters are:
Flat fee = $15
Rate = $8
To determine the function rule of the scenario, we make use of the following template equation
f(x) = Flat fee + Rate * Number of hours
Where
f(x) = total and x = number of hours
So, we have
f(x) = Flat fee + Rate * x

f(x) = 15 + 8x

Slope is 1/4 (0.25) while y-intercept is 5.

We can get the slope by using any two points

Mathematically; slope

To get the y-intercept, we proceed
kindly recall that the equation of a straight line is;
y = mx + c
where m is the slope and c is the y-intercept
Let’s take any of the points (28,12)
