The perimeter of the rectangle is (23.5y + 1) feet.
The perimeter of the rectangle formula:
The perimeter = the width + the length + the width + the length
The perimeter = 2 × (the width + the length)
The perimeter = 2 × ((4.25y - 7.5) + (7.5y + 8))
The perimeter = 2 × ((4.25y + 7.5y) + (- 7.5 + 8)
The perimeter = 2 × (11.75y + 0.5)

when looking to invest money in a company by purchasing stock why is it important to look at many companies to invest
Evaluating multiple companies before making an investment decision helps to make informed decisions, diversify your portfolio, and maximize returns.
It is critical to consider multiple companies before investing because:
Diversification reduces the risk of loss because the performance of one company does not determine the overall performance of your portfolio.
Opportunity Cost: Comparing and selecting the best investment options allows you to avoid missing out on potential higher returns by evaluating multiple companies.
Due Diligence: Investing in a company necessitates extensive research and due diligence. When you look at multiple companies, you can compare financial statements, management, products, and other factors that can affect stock performance.
Finally, evaluating multiple companies prior to making an investment decision allows you to make informed decisions, diversify your portfolio, and maximize returns.

Car X travels 174 miles in 3 hours.
a. Write the equation of the line that describes the relationship between distance and time. Use x for the time in hours and y for the distance in miles.
b. What is the graph that represents the relationship between distance and time for Car X? Explain.
Answer:
Step-by-step explanation:
a. The equation of the line that describes the relationship between distance and time for Car X can be found by using the slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
To find the slope (m), we can use the formula: m = (change in y) / (change in x) = (distance traveled) / (time elapsed) = 174 miles / 3 hours = 58 miles per hour.
Since the car starts at time x = 0 and has traveled 174 miles at time x = 3, the y-intercept (b) can be found by setting x = 0 and solving for y: y = 58x + b, and y = 174 when x = 3, so b = 174 - 58(3) = -160.
Putting it all together, we get the equation: y = 58x - 160.
b. The graph that represents the relationship between distance and time for Car X is a line that passes through the point (0, -160) and has a slope of 58. This line represents the linear relationship between the distance traveled and the time elapsed for Car X.
The y-intercept of -160 represents the distance traveled when time is equal to 0. The slope of 58 represents the rate of change of the distance traveled with respect to time. This means that for every hour that passes, Car X travels 58 miles.

A department store buys 300 shirts at a cost of $1,800 and sells them for $9 each. What is the percent markup? A department store buys 300 shirts at a cost of $1,800 and sells them for $9 each. What is the percent markup?
The percent markup for the cost of shirt = 50%
Let us assume that the cost of each shirt be x dollars
A department store buys 300 shirts at a cost of $1,800.
Using unitary method the price of each shirt would be,
x = 1800/300
x = 6 dollars
A department store sells 300 shirts for $9 each.
So, Selling price of one shirt = $9
Price markup = Selling price - Cost price
= $9 - $6
= $3
The percent markup would be,
p = (Price markup / cost price) × 100
p = (3/6) × 100
p = 50%

Step-by-step explanation:
A particle is moving along a spiral path defined by the equation r = a * e^(b * θ), where a and b are constants. Determine the velocity of the particle at a given value of θ.
Step-by-step explanation:
The velocity of the particle at a given value of θ can be found by taking the derivative of the position vector with respect to time:
v(θ) = dr/dt = dr/dθ * dθ/dt = dr/dθ * ω
where ω is the angular velocity and dr/dθ is the derivative of the position vector with respect to θ.
The position vector r = a * e^(b * θ) * i + a * b * e^(b * θ) * j
Taking the derivative with respect to θ:
dr/dθ = a * b * e^(b * θ) * i + a * b^2 * e^(b * θ) * j
So the velocity of the particle is given by:
v(θ) = a * b * e^(b * θ) * ω * i + a * b^2 * e^(b * θ) * ω * j
Answer:
Step-by-step explanation:
v(θ) = a * b * e^(b * θ) * ω * i + a * b^2 * e^(b * θ) * ω * jj

The diagram shows a circle with centre O.
A, B & C lie on the circumference of this circle.
Given that AC is a diameter of the circle and ∠BCA = 5 × ∠BAC, find the size of ∠BCA as highlighted in the diagram.
Answer:
∠ BCA = 75°
Step-by-step explanation:
∠ ABC = 90° ( angle in a semicircle )
then the 2 remaining angles in Δ ABC = 90° , that is
∠ BAC + ∠ BCA = 90° ( ∠ BCA = 5 × ∠ BAC )
∠ BAC + 5 ∠ BAC = 90°
6 ∠ BAC = 90° ( divide both sides by 6 )
∠ BAC = 15°
Then
∠ BCA = 90° - 15° = 75°
What expression represents the value of y?
Answer:
Second choice:
[tex]\mbox{\large y = \sqrt{wz}}[/tex]
Step-by-step explanation:
Consider the right triangle ABC
By the Pythagorean theorem,
AB² = BC² + AC²
BC = x, AC = (w + x) and AB = v
Plug in above values
(w + z)² = v² + x² (1)
In right triangle BCD,
BC² = BD² + CD²
Plugging in values we get
x² = w² + y² (2)
In right triangle ABD
AB² = BD² + AD²
v² = y² + z² (3)
Plug in values of x² from eq (2) and v² from eq 3 into equation (1) to get
(w + z)² = y² + z² +w² + y²
Left side (w + z)² = w² + 2wz + z²
==> w² + 2wz + z² = y² + z² +w² + y²
w² and z² cancel out since they are on both sides of the equation with same sign
=> 2wz = y²+y²
2wz = 2y²
Divide by 2:
wz = y²
Switch sides:
y² = wz

You must pay $2,089.90 at the end of the month to bring the balance to the acceptable debt ratio percentage.
How to determine the amount to payFrom the question, we have the following parameters that can be used in our computation:
Balance = $3589.90
Credit limit = $5000
To determine the acceptable debt ratio percentage, we make use of 30% minimum credit utilization rate.
So, the acceptable balance on the credit card is:
Balance = $5,000 * 30% = $1,500.
Since the current balance is $3,589.90, we have
Payment = $3,589.90 - $1,500
Payment = $2089.9

Suppose you know that ∠S and ∠Y are complementary and that m∠S = 5(m∠Y) − 240°. Find m∠Y.
The measure of angle Y, according to the stated statement, is 55 degrees.
What does the term "complementary" mean?An adverb used to describe something which goes together with something else and improves or completes it is complimentary (as in complementary colors)
The total of two complimentary angles is 90 degrees. As a result, we have:
m∠S + m∠Y = 90
Substituting the given equation m∠S = 5(m∠Y) − 240°, we get:
5(m∠Y) − 240° + m∠Y = 90
By merging like variables in the equation, we can reduce it to:
6(m∠Y) - 240° = 90
Adding 240 to both sides, we get:
6(m∠Y) = 330
Dividing both sides by 6, we get:
m∠Y = 55
Therefore, the measure of angle Y is 55 degrees.

The probability of drawing at least 7 clubs in 15 draws from a standard deck of 52 cards is approximately 0.496.
The number of ways to draw 7 or more clubs in 15 draws can be found by using the cumulative distribution function for the binomial distribution. This distribution models the number of successful outcomes (clubs) in n independent trials (card draws), each with the same probability of success (drawing a club).
