mRS = 121°
Calculus HELP PLEASE? A highway runs due north. A car traveling at 50 mph exits the highway at a 30° angle. After driving another 1.5 hours at the same speed and direction, how far away is the car from the highway?
Answer:
37.5 miles is the answer.
Step-by-step explanation:
Since car is travelling with a speed = 50 mph
Angle between the highway and the track on which the car is travelling = 30°
Now we know sin∅ = distance between highway and the car/Distance traveled by the car on the new track
Distance traveled by the car in 1.5 hours = speed × time
= 50 × 1.5 = 75 mi.
Therefore sin 30° = x/75
x = 75×sin30° = 75 × 1/2 = 37.5 mi.
Therefore the answer is 37.5 mi away.

A classic counting problem is to determine the number of different ways that the letters of "personnel""personnel" can be arranged. find that number.
The number of different ways in which the letter of “PERSONNEL” can be arranged is [tex]\boxed{\bf 90,720}[/tex].
Further explanation:
A permutation is an arrangement of objects in their order in which we find number of ways that can occur in a period of time.
If all the letters are different then the number of arrangement can be written as follows:
[tex]\boxed{\begin{aligned}P(n)&=n!\\&=n\cdot (n-1)\cdot (n-2)...2\cdot 1\end{aligned}}[/tex]
The number of different permutation can be calculated as follows:
[tex]\boxed{p(n)=\dfrac{n(n-1)(n-2)...2\cdot 1}{n_{1}!\cdot n_{2}!}}[/tex]
Here, [tex]n_{1}[/tex] and [tex]n_{2}[/tex] are the different kind of object such that [tex]n_{1}+n_{2}+n_{3}+\cdot \cdot+n_{k}=n[/tex].
Given:
The given word is “PERSONNEL”.
Calculation:
Step 1:
First consider that all the letters are different i.e, repetition of letter is allowed.
The given word “PERSONNEL” has [tex]9[/tex] letters.
Therefore, the number of ways for arranging nine letters can be calculated as follows:
[tex]\begin{aligned}P(9)&=9\cdot (9-1)\cdot (9-2)\cdot \cdot 2\cdot 1\\&=9\cdot 8\cdot 7\cdot 6\cdot 5\cdot 4\cdot3 \cdot 2\cdot 1\\&=362,880\end{aligned}[/tex]
Therefore, the different arrangements of the given word is [tex]362,880[/tex].
Step 2:
Since, the letter N and E is repeated two times in given word “PERSONNEL” then the half of the arrangement is repeated of these two letters.
Use the formula for finding the number of distinguishable permutation. It can be calculated as follows:
[tex]\begin{aligned}\text{Number of permutation}&=\dfrac{362880}{2!\cdot 2!}\\&=\drac{362880}{4}\\&=90,720\end{aligned}[/tex]
The number of different ways that the letter of “PERSONNEL” can be arranged is [tex]90,720[/tex].
Thus, the number of different ways that the letter of “PERSONNEL” can be arranged is [tex]\boxed{\bf 90,720}[/tex].

Chapter: Permutation
Keywords: Permutation, combination, personnel, counting, arrangement, different ways, order, letters, different ways, repetition, arranged objects, distinguishable permutation, counting problem.
The number of different ways to arrange the letters of 'personnel' is calculated using combinatorics and permutation formulas, resulting in 151,200 unique arrangements.
To find the number of different ways to arrange the letters of the word "personnel", we must use the principles of combinatorics and permutations.
The word 'personnel' consists of 9 letters with repetitions: there are three E's, two N's, one P, one S, one O, and one L. To count the number of unique arrangements, we start with the total factorial of all letters, which is 9!, but then we need to account for repeated letters by dividing by the factorials of the frequency of each repeating letter.
This results in the following permutation formula:
N! / (n1!)n2!...nk!
Where N is the total number of letters, and n1, n2, ..., nk are the number of times each unique letter is repeated.
So for 'personnel': 9! / (3!)(2!) = 151,200
There are therefore 151,200 unique ways to arrange the letters in 'personnel'.

The price of 6 pretzels is $5.10. Simon and Sofia bought 8 pretzels an shared the cost equally. How much did each person pay?
Answer:
$3.40
Step-by-step explanation:
To find out the amount each person paid, let's find the total cost of the pretzels first.
6 pretzels ----- $5.10
1 pretzel ----- $5.10 ÷6= $0.85
8 pretzels ----- 8($0.85)= $6.80
The total cost of 8 pretzels is thus $6.80.
Since the total cost was shared equally amongst two people, each person paid half of the total cost.
Amount each person paid
= $6.80 ÷2
= $3.40
By taking a quotient between the total cost and the number of people, we can see that each one pays $3.40
How much did each person pay?We know that the price of 6 pretzels is $5.10, then the price for each pretzel is given by the quotient:
$5.10/6 = $0.85
We know that Simon and Sofia bought 8 pretzels, so they pay:
P = 8*$0.85 = $6.80
And they divide that evenly between the two, so we can take the quotient:
p = $6.80/2 = $3.40
That is the amount that each person pays.

A) f has a relative minimum at x = 1.5
B) f has relative maximum at x = -1.5
C) f is decreasing on the interval from x = 1 to x = 2
D) none of these are true
https://seminole.flvs.net/webdav/assessment_images/educator_apcalcab_v14/08_01_04.gif
The only statement that is true as regards the graph of f ′(x) is;
C: f is decreasing on the interval from x = 1 to x = 2
We are told that the graph of f ′(x) has x-intercepts at x = –3, x = 1 and x = 2.Now, f'(x) is simply the derivative of f(x) and the derivative of f(x) is defined as the slope.
Since x-intercepts of the derivative are at x = –3, x = 1 and x = 2. It means that the values of x that will make the slope to be zero are x = –3, x = 1 and x = 2.Now, the minimum for the derivative graph usually happens when the the graph goes from negative to positive. This means that the graph is decreasing when the x-intercepts of the slope is positiveIn contrast the graph is increasing when the x-intercepts of the slope is negative.
Let us look at the options;
Option A; This is not correct because the derivative has to be zero at minimum point. Option B; This is not also correct because the derivative has to be zero at maximum point.Option C; This is correct because slope is positive when the graph is decreasing and from x = 1 to x = 2 is positive interval.Read more about graph of derivative of a function at; https://brainly.com/question/2284808

How would paying off the lowest outstanding balance credit card first be beneficial over paying off the one with the highest interest rate?
Paying off the lowest outstanding balance credit card first can be beneficial for motivation and momentum, even if it's not the most mathematically efficient approach.
Explanation:When paying off credit card debt, it can be beneficial to start by paying off the credit card with the lowest outstanding balance. This approach is called the Snowball Method and is popularized by financial expert Dave Ramsey. The Snowball Method focuses on tackling the smallest debt first, regardless of the interest rate, as it provides a psychological boost and motivates individuals to continue paying off their debts.
By paying off the smallest debt first, you can quickly eliminate one of your credit card balances. This can give you a sense of accomplishment and momentum to continue paying off your other debts. It's important to note that while the Snowball Method may not be the most mathematically efficient approach in terms of saving on interest payments, it can be effective in helping individuals stay motivated and committed to paying off their debts.

Final answer:
The measure of dispersion which is not measured in the same units as the original data is the variance.
Explanation:
The measure of dispersion which is not measured in the same units as the original data is the variance. The variance is a squared measure and does not have the same units as the data. On the other hand, the standard deviation is derived from the variance and it measures the spread in the same units as the data.
Then again, the standard deviation, which is the square foundation of the fluctuation, is estimated in similar units as the first information. It gives a proportion of the spread of the information that is all the more effectively interpretable. The middle is a proportion of focal inclination and doesn't give data about the scattering or spread of the information.
The coefficient of assurance, otherwise called R-squared, is a proportion of how well the relapse line fits the information and isn't straightforwardly connected with scattering.

Find the equation of the line with the given properties: slope of 2, contains the point ( 4, -3).
Answer:
y = 2x - 11
Step-by-step explanation:
We are given that a line has a slope of 2 and passes through the point (4, -3).
As the question doesn't specify, we can write the equation of the line in any format.
There are 3 ways to write the equation of the line. They are:
Slope-intercept form, which is y=mx+b, where m is the slope and b is the value of y at the y intercept.Standard form, which is ax+by=c, where a, b, and c are free integer coefficients, however a and b cannot be 0 and a cannot be negative. Point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.Although while all of these choices are valid, let's write the equation in slope-intercept form, as that is the most common way to write the equation of the line.
As we are already given the slope of the line, we can immediately plug it into the equation as m.
Replace m with 2.
y = 2x + b
Now we need to find b.
As the line contains the point (4, -3), we can use its values to help solve for b.
Substitute 4 as x and -3 as y.
-3 = 2(4) + b
Multiply.
-3 = 8 + b
Subtract 8 from both sides.
-11 = b
Substitute -11 as b in the equation.
y = 2x - 11

Group of kids rode horses to canyon. 20 eyes 30 legs between them. How many horses
Final answer:
To solve this problem, we set up equations based on the total number of eyes and legs. By solving the system, we find that the group consists of 5 horses.
Explanation:
The question asks us to solve a problem involving a group of kids and horses by using the given information about the total number of eyes and legs. Since humans have two eyes and two legs, and horses have two eyes and four legs, we can set up a system of equations to find the solution.
Let's denote the number of kids as 'k' and the number of horses as 'h'. Since each human and horse has two eyes, the total number of eyes is given by the equation: 2k + 2h = 20. Similarly, the total number of legs is given by the equation: 2k + 4h = 30. Solving these equations will give us the number of kids and horses in the group.
Solving for 'k' from the first equation gives us k = 10 - h. Substituting this into the second equation gives us 2(10 - h) + 4h = 30. Simplifying this equation results in 20 - 2h + 4h = 30, which further simplifies to 2h = 10, and thus h = 5. Therefore, there are 5 horses in the group.
