Answer:
m = 7 and b = -12 therefore y = 7x - 12
Step-by-step explanation:
From the question we are given the first derivative of the function g to be 7, and it is known that the first derivative of a function is the slope, therefore the slope, m = 7.
Since we are looking for 'b' at x = 3 and we know that our slope is 7, we have:
g(3) = 7*3 + b. We are given g(3) = 9 so we have:
9 = 21 + b and b = -12.
Therefore, m = 7 and b = -12 and the equation of the line is y = 7x - 12.
What is the coefficient of q for (2/3q-3/4)+(-1/6-2)
The coefficient of q is -1/12
What is coefficient?
A coefficient refers to a number or quantity placed with a variable. It is usually an integer that is multiplied by the variable and written next to it. The variables which do not have a number with them are assumed to be having 1 as their coefficient.
Now, Come to the question:
To find the coefficient of q
\((\frac{2}{3q}-\frac{3}{4}) +(\frac{-1}{6} -2)\)
Taking L.C.M

The sum of five consecutive integers is 46 less than 9 times the least of the integers. Find the largest consecutive integer.
Question 6 options:
A)
17
B)
10
C)
18
D)
19
Answer:
C) 18
Step-by-step explanation:
Let x represent the largest of the five consecutive integers. Then (x -4) is the smallest, and the sum of the five of them is ...
sum = 5((x +(x -4))/2 = 5x -10
That sum is 46 less than 9 times the smallest.
__
This relation can be written as ...
5x -10 = 9(x -4) -46
72 = 4x . . . . . . . . . . . . add 82-5x and simplify
18 = x . . . . . . . . . divide by 4
The largest of the consecutive integers is 18.
_____
Additional comment
Here, we have used the variable to represent what the problem is asking for--the largest of the integers. Often, in consecutive integer problems, it is convenient to let a variable represent the middle (or average) value of the consecutive integers. If we do that here, then sum of the 5 integers would be 5x, and the relation to find x would be ...
5x +46 = 9(x -2)
This resolves to 64=4x ⇒ x=16, so the largest integer is x+2=18. The number of steps is about the same, but the sum is easier to find, and there aren't as many constant terms to play with in solving for x.

c.
previous balance method
d.
there is not enough information to determine which method was used
Answer:
I got A and it was right
Step-by-step explanation:
The "Previous Balance Method" seems to be the one that aligns with the provided information.
Given that:
Beginning balance on 6/1: $265.40
Payment on 6/6: $90.00
Purchase on 6/16: $43.33
Purchase on 6/22: $37.71
They have also given the finance charge for June, which is $3.56.
The different methods according to the options are:
a. Daily Balance Method: This method calculates the finance charge based on the daily balance throughout the billing cycle. It takes into account daily changes in the balance due to transactions and payments.
b. Adjusted Balance Method: This method calculates the finance charge based on the adjusted balance at the end of the billing cycle. The adjusted balance is the beginning balance minus any payments made during the billing cycle.
c. Previous Balance Method: This method calculates the finance charge based on the previous month's balance, regardless of any payments made during the current billing cycle.
Based on the given information, we don't have the exact daily balances or the specific date of the finance charge calculation. However, we know the finance charge for the entire month of June is $3.56.
Out of the three methods, the "Previous Balance Method" seems to be the one that aligns with the provided information. It calculates the finance charge based on the previous month's balance, which would include the beginning balance on 6/1 and any outstanding balance from previous months.
So the correct answer is option C, Previous Balance Method.

In a random sample of 2,305 college students, 339 reported getting 8 or more hours of sleep per night. Create a 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night. Use a TI-83, TI-83 plus, or TI-84 calculator, rounding your answers to three decimal places.
Answer:
The 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.133, 0.161).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which
z is the zscore that has a pvalue of \(1 - \frac{\alpha}{2}\).
For this problem, we have that:
\(n = 2305, \pi = \frac{339}{2305} = 0.147\)
95% confidence level
So \(\alpha = 0.05\), z is the value of Z that has a pvalue of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).
The lower limit of this interval is:
\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.147 - 1.96\sqrt{\frac{0.147*0.853}{2305}} = 0.133\)
The upper limit of this interval is:
\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.147 + 1.96\sqrt{\frac{0.147*0.853}{2305}} = 0.161\)
The 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.133, 0.161).

Write a completely simplified rational expression that represents the exchange rate Salma will receive in dollars per euro. Explain how you came up with your expression.
The exchange rate that She will receive is an algebraic expression
The exchange rate that Salma will receive in dollars per euro is \(\frac{12x - 9}{4x -6}\)
How to determine the exchange rateThe amount of dollars with Salma is given as:
\(Dollar = \frac{12x^2 + 15x - 18}{2x^2 + 14x + 20}\)
The amount of Euro she can buy is:
\(Euro = \frac{2x^2 -x-3}{x^2 + 6x +5}\)
Let the exchange rate be r.
So, we have:
\(Dollar * \frac 1r = Euro\)
The equation becomes
\(\frac{12x^2 + 15x - 18}{2x^2 + 14x + 20}* \frac 1r = \frac{2x^2 -x-3}{x^2 + 6x +5}\)
Factorize the expressions
\(\frac{3(x + 2)(4x - 3)}{2(x + 5)(x +2)}* \frac 1r = \frac{(x +1)(2x -3)}{(x + 5)*x + 1)}\)
Cancel out the common factors
\(\frac{3(4x - 3)}{2}* \frac 1r = \frac{(2x -3)}{1}\)
Make r the subject
\(\frac 1r = \frac{2(2x -3)}{3(4x - 3)}\)
Expand
\(\frac 1r = \frac{4x -6}{12x - 9}\)
Make r the subject
\(r = \frac{12x - 9}{4x -6}\)
Hence, the exchange rate is \(\frac{12x - 9}{4x -6}\)

The graph is increasing on the interval x > –3.
The graph is positive only on the intervals where x < –7 and where
x > 1.
The graph is negative on the interval x < –4.
Answer:
The vertex of the function is at (–3,–16)
The graph is increasing on the interval x > –3
The graph is positive only on the intervals where x < –7 and where
x > 1.
Step-by-step explanation:
The graph of \(f(x)=(x-1)(x+7)\) has clear zeroes at \(x=1\) and \(x=-7\), showing that \(f(x) > 0\) when \(x < -7\) and \(x > 1\). To determine where the vertex is, we can complete the square:
\(f(x)=(x-1)(x+7)\\y=x^2+6x-7\\y+16=x^2+6x-7+16\\y+16=x^2+6x+9\\y+16=(x+3)^2\\y=(x+3)^2-16\)
So, we can see the vertex is (-3,-16), meaning that where \(x > -3\), the function will be increasing on that interval

You are playing a game where you draw a card from a standard deck, and you will win $13 if you draw a face card, $6 if you draw an ace and lose $3 if you draw any other card. What is the expected gain from this game?
Answer:
There are 12 face cards and 4 aces in a standard deck, so the probability of drawing a face card is 12/52 = 3/13, the probability of drawing an ace is 4/52 = 1/13, and the probability of drawing any other card is 1 - 3/13 - 1/13 = 9/13.
The expected gain from drawing a face card is $13, from drawing an ace is $6, and from drawing any other card is -$3. Therefore, the expected gain from this game is:
(3/13)($13) + (1/13)($6) + (9/13)(-$3) = $0
This means that over many games, on average, you would neither win nor lose any money playing this game.

"los ceros son 0, -1, 1, 3/2, P(-3) = 300"
The polynomial with the given zeros is:;
P(x) = (300/108)*x*(x + 1)*(x - 1)*(x - 3/2)
How to find the polynomial?Remember that if a polynomial has the zeros a, b, c, and d, then we can write it as:
P(x) = K*(x - a)*(x - b)*(x - c)*(x - d)
Where K is a coefficient.
Here the zeros are 0, -1, 1, 3/2
Then we can write:
P(x) =K*(x - 0)*(x + 1)*(x - 1)*(x - 3/2)
P(x) =K*x*(x + 1)*(x - 1)*(x - 3/2)
We also know that when x = -3, P(x) = 300
Then we can write:
300 = K*(-3)*(-3 + 1)*(-3 - 1)*(-3 - 3/2)
300 = K*(-3)*(-2)*(-4)*(-9/2)
300 = K*108
300/108 = K

Find the perimeter of the triangle whose vertices are (−7,−1), (5,−1), and (5,4). Write the exact answer. Do not round.
The perimeter of the triangle is 30 units
How to determine the perimeter?The vertices are (−7,−1), (5,−1), and (5,4).
Start by calculating the distance between the vertices using:
\(d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2\)
So, we have:
\(d1 = \sqrt{(-1 + 1)^2 + (5 + 7)^2\)
d1 = 12
\(d2 = \sqrt{(-1 - 4)^2 + (5 - 5)^2\)
d2 =5
\(d3 = \sqrt{(-1 - 4)^2 + (-7 - 5)^2\)
d3 = 13
The perimeter is then calculated as:
P = d1 + d2 + d3
This gives
P = 12 + 5 + 13
Evaluate
P = 30
Hence, the perimeter of the triangle is 30 units
