car, and arc, however ar is also a word, not distinctly though.
compute the arc length of the curve:
x(t)=2t^(3/2)+2, y(t)=2t-3, 0<=t<=2
The length of the arc is = [tex]\frac{2}{27}22^{\frac{3}{2} }[/tex]m
What is Integration ?In mathematics, an integral lends numerical values to functions to represent concepts like volume, area, and displacement that result from combining infinitesimally small amounts of data. Integration is the action of locating integrals.
According to the given information
We can find the length of the arc by
L = [tex]\int\limits^a_b {\sqrt{\frac{dx}{dt} ^{2}+\frac{dy}{dt} ^{2} } } \, dt[/tex]
Find the derivative of x w.r.t to t
dx/dt = [tex]3t^{\frac{1}{2} }[/tex]
Find the derivative of y w.r.t to t
dy/dt = 2
Putting the values in above equation
We get
L = [tex]\int\limits^a_b {\sqrt{\frac{dx}{dt} ^{2}+\frac{dy}{dt} ^{2} } } \, dt[/tex]
L= [tex]\int\limits^2_0 {\sqrt{9t+4} } \, dt[/tex]
L = [tex]\frac{2}{27}(9t+4)^{\frac{3}{2} }[/tex]
limit approaches from 0 → 2
Hence
The length of the arc is = [tex]\frac{2}{27}22^{\frac{3}{2} }[/tex]m

Adam is wanting to start saving for retirement but they don’t know how much they can afford to save from their monthly budget. Help Adam find their monthly cash flow.
Adam works at Tim Horton’s making $15/hour, 32 hours a week. (Assume they take no vacations.)
Expenses are: Rent: $650/month, Groceries: $75/week, Utilities: $120/month, Car Insurance: $118/month, Gasoline: $30/week, and Miscellaneous: $400/month
Saving for Retirement (20 Pts)
Now, let’s pretend you are Adam. How much of your ending cash flow would you want to save for retirement? This will be the amount they will put in the IRA monthly.
Retirement Amount (20 Pts)
If Adam retires in 35 years and finds an IRA for 4.8%, how much money will be in their retirement account when they retire?
Amount Deposited (20 Pts)
How much will Adam deposit in total to their IRA?
Interest Accrued (20 Pts)
How much will Adam accrue in interest from their IRA?
1) Adam's monthly cash flows are:
Cash Inflows = $2,080Cash Outflows = $1,743.2) I would save $300 monthly from the ending cash flow balance for retirement savings.
3) If Adam retires in 35 years and finds an IRA for 4.8%, the future value of their retirement account will be $326,070.43 when they retire.
4) In 35 years, Adam will deposit $126,000 in total to their IRA.
5) The accrued interest from the IRA will be $200,070.43.
What is the future value?The future value represents the balance in Adam's retirement savings account after 35 years of depositing $300 monthly at 4.8% interest.
The future value is computed by compounding the periodic deposits (present values).
Adam's total monthly earnings = $2,080 ($15 x 32 x 52 x 1/12)
Monthly Expenses:
Rent $650
Groceries $325 ($75 x 52 x 1/12)
Utilities $120
Car Insurance $118
Gasoline $130 ($30 x 52 x 1/12)
Miscellaneous $400
Total monthly expenses = $1,743
Ending cash flows = $337 ($2,080 - $1,743)
Retirement period = 35 years
IRA interest rate = 4.8%
Monthly savings = $300
N (# of periods) = 420 months (35 years x 12)
I/Y (Interest per year) = 4.8%
PV (Present Value) = $0
PMT (Periodic Payment) = $300
Results:
Future Value (FV) = $326,070.43
Sum of all periodic deposits = $126,000 ($300 x 420)
Total Interest = $200,070.43

Gavin already had 12 rolls of towels, and he is buying 3 rolls per week.
What is slope?Slope tells us the change between two points given, and is shown by the change in the y coordinate divided by the corresponding change in the x coordinate.
Given that, Gavin is stocking up on paper towel rolls. He already has some at his house, and begins buying more every week at a constant rate. The line y = 3x + 12 represents this scenario.
Here the equation is y = 3x+12
When comparing with standard equation of the line, y = mx+c where m is slope, we get,
m = 3 and c = 12
Therefore, the change is 3, that means, he is buying 3 rolls per week,
and the constant is 12 that tells that he already have 12 rolls in stock.
Hence, a) he is buying 3 rolls every week, b) he has 12 rolls in stock.

A public health official claims that more than 5.8 percent of the population suffers from long-term COVID symptoms. Use p, the true percentage of the population that suffers from long-term COVID. Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (μ, ρ, σ) for the indicated parameter. A. H0 : p = 5.8% H1 : p < 5.8% B. H0 : p = 5.8% H1 : p > 5.8% C. H0 : p = 5.8% H1 : p ≤ 5.8% D. H0 : p = 5.8% H1 : p ≥ 5.8%
Answer:
B. H0 : p = 5.8% H1 : p > 5.8%
The null hypothesis, denoted H0, is a statement that asserts that there is no significant difference between a sample statistic and a population parameter. In this case, the null hypothesis would be that the true percentage of the population that suffers from long-term COVID symptoms is equal to 5.8 percent. This is represented symbolically as H0 : p = 5.8%.
The alternative hypothesis, denoted H1, is a statement that contradicts or negates the null hypothesis. In this case, the alternative hypothesis would be that the true percentage of the population that suffers from long-term COVID symptoms is greater than 5.8 percent. This is represented symbolically as H1 : p > 5.8%.

Match the equations of perpendicular lines. (You will not use all answer choices on the right.)
The equations of the perpendicular lines are matched as follows:
y = 1/3x + 4 → y = -3x - 4.
y = 2/5x - 7 → y = -5/2x + 7.
y = -5/2x + 8 → y = 2/5x - 6.
y = -2x + 6 → y = 1/2x + 3.
y = 7/5x - 9 → y = -5/7x - 11.
What are the Equations of Perpendicular Lines?If the equations of lines are written in slope-intercept form as y = mx + b, where the slope is the value of m, then the slope of lines that are perpendicular to each other will be negative reciprocal of each other.
For example, if the equation of a line is y = 1/2x + 5, the equation of a line that is perpendicular to it would have a slope of -2.
y = 1/3x + 4 has a slope of 1/3. The negative reciprocal of 1/3 is -3. Therefore, the line that is perpendicular to it would be, y = -3x - 4.
y = 2/5x - 7 has a slope of 2/5. The negative reciprocal of 2/5 is -5/2. Therefore, the line that is perpendicular to it would be, y = -5/2x + 7.
y = -5/2x + 8 has a slope of -5/2. The negative reciprocal of -5/2 is 2/5. Therefore, the line that is perpendicular to it would be, y = 2/5x - 6.
y = -2x + 6 has a slope of -2. The negative reciprocal of -2 is 1/2. Therefore, the line that is perpendicular to it would be, y = 1/2x + 3.
y = 7/5x - 9 has a slope of 7/5. The negative reciprocal of 7/5 is -5/7. Therefore, the line that is perpendicular to it would be, y = -5/7x - 11.

We know that Martin will need 16.5 gallons of gasoline using mathematical operations.
What are mathematical operations?An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
The operation's arity is determined by the number of operands.
The rules that specify the order in which we should solve an expression involving many operations are known as the order of operations.
PEMDAS stands for Parentheses, Exponents, Multiplication, Division, and Addition Subtraction (from left to right).
So, each day Martin travels:
12 * 2 / 24 miles from home to work and back home.
As she works for 22 days: 24*22 = 528 miles
So, the equation can be:
32x = 528

Challenge The members of the city cultural center have decided to put on a play once a night for a week. Their
auditorium holds 500 people. By selling tickets, the members would like to raise $2,050 every night to cover all expenses.
Let d represent the number of adult tickets sold at $6.50. Let s represent the number of student tickets sold at $3.50 each.
If all 500 seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise
exactly $2,050? At one performance there were three times as many student tickets sold as adult tickets. If there were
480 tickets sold at that performance, how much below the goal of $2,050 did ticket sales fall?
There are 100 students and 400 adults.
The 480 tickets sold had a $10 fall in ticket sales.
What is system of equations?
A set of one or more equations involving numerous variables is referred to as a system of equations. The variable mappings that satisfy all component equations are the solutions to systems of equations, or the points where the components of these equations intersect.
Let d be the number of adults and y be the number of students.
⇒ d + s = 500 ..(1)
The number of adult tickets sold at $6.50 and the number of student tickets sold at $3.50 each.
⇒ 6.5d + 3.5s = 2050 ..(2)
From equation (1) d = 500 - s
Plug the value of d in equation (2)
6.5(500 - s) + 3.5s = 2050
3250 - 6.5s + 3.5s = 2050
3250 - 3s = 2050
3s = 3250 - 2050
3s = 1200
s = 400
Plug s = 400 in d = 500 - s
⇒ d = 500 - 400 = 100
Hence, there are 100 students and 400 adults.
Now, at one performance there were three times as many student tickets sold as adult tickets.
⇒ s = 3d
3d - s = 0 ..(3)
d + s = 480 ..(4)
⇒ 4d = 480
d = 120 Adults
Plug d = 120 in equation (4)
120 + s = 480
s = 480 - 120
s = 360 Students
The money earned from these 480 people is
120 * 6.5 + 360 * 3.5 = 780 + 1260 = $2040.
$2040 - $2040 = $10
Hence, the 480 tickets sold had a $10 fall in ticket sales.

how do you solve for the y intercept ?
Y Intercept is the point where a line or curve crosses the y-axis of a graph or in other words where x=0.
Knowledge of the y-intercept can be used when graphing lines or when writing an equation in slope-intercept form.
Formula to calculate y-intercept.
We get the y-intercept by using the equation of a straight line which is;
y = mx + b
Where;
m is the gradient of the slope
b is the y-intercept.
We can use the following formula to calculate the y-intercept.
y – a = m ( x – b )
a and b being a point on a line.
Example:
Suppose you have a straight line whose gradient is 3 and a point 2,1, calculate its y-intercept.
Since the y-intercept is when x=0, therefore;
y – 2 = 3 ( x – 1 )
y – 2 = 3x – 1
y = 3x – 1
Therefore, the number that has replaced b is -1, which means that -1 is the y-intercept.

Calculate the total price for the car and the bank fees. Then, find the monthly payment if you get a $5 year loan to buy
the car from Bank AAA?
The total price for the car is $26000.
The monthly payment is $500.
How to calculate the price?From the information illustrated, Bank AAA is charging 4% in total fees to borrow money for a car loan and the person want to buy a car that costs $25,000.
The total amount that will be paid will be:
= Amount of car + Interest
= $25000 + ($25000 × 4%)
= $26000
The amount on a 5 year loan will be:
Interest = PRT
= ($25000 × 4% × 5)
= $5000
Total amount to be paid = $25000 + $5000
= $30000
Monthly payment = Total amount / Number of months
= $30000 / 60

pls help
Answer: (-1,1)
Step-by-step explanation:
since y is equal to 2x+3 you can sub 2x+3 into the y value of 12x+4y=-8
12x+4(2x+3)=-8
Multiply the numbers inside the parentheses using the distributive property
12x+8x+12=-8
Combine like terms
20x+12=-8
Isolate x by moving all other numbers to the right side
Subtract 12 on both sides
20x+12-12=-8-12
20x=-20
divide both sides by 20 to isolate and get the value of x
x=-1
Now that we know the x value substitute the value of x in any of the above equations. I am using y=2x+3

The solution to the given system of equations is the point (-1, 1) which is determined by the substitution method.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The system of equations is given as:
12x + 4y = −8
y = 2x + 3
To solve this system of equations using the substitution method, you can substitute the second equation into the first equation to eliminate one of the variables.
Substituting y = 2x + 3 into the first equation gives:
12x + 4(2x + 3) = -8
12x + 8x + 12 = -8
20x + 12 = -8
20x = -20
x = -1
Substituting this value of x back into the second equation gives:
y = 2(-1) + 3
y = -2 + 3
y = 1
Therefore, the solution to the system of equations is the point (-1, 1).

Simplify -x-(-4x-6)=6
Answer:
To simplify the given equation, we can start by using the rules of algebra to rearrange the terms and combine like terms on both sides of the equation. This gives us:
-x - (-4x - 6) = 6
We can then distribute the negative sign on the left side of the equation to get:
-x + 4x + 6 = 6
We can then combine like terms on the left side of the equation to get:
3x + 6 = 6
We can then subtract 6 from both sides of the equation to get:
3x = 0
We can then divide both sides of the equation by 3 to get the final result:
x = 0
Therefore, the simplified form of the given equation is x = 0.

θ is an acute angle. Find the value of θ in degrees.
sec(θ)=2
The value of θ is 60°.
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin, cos , tan , cosec , sec and cot
Let the angle be θ , that is;
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
Thus, tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data that the angle be represented as θ
Now , we are given that the angle θ is acute
Since Acute angles measure less than 90 degrees
So , the value of θ < 90°
when the value of sec θ = 2
cos θ = 1/sec θ
, cos θ = 1/2
