the pressure exerted on the floor by the heel of someone's shoe is inversely proportional to the square of the width of the heel of their shoe. When Megumi wears 2cm wide heels, she exerts a pressure of 400 kPa. Determine a function to represent the pressure, p, exerted by Megumi if she wears heels of width, w.
Answers
first of all you need to find k
But I kind of don't like the units of each value so let say
400KPa = 4 * 10^5 Pa = 4 * 10^5 N/m^2
2 cm = 2 * 10^-2 m
input values in the equation
4*10^5 = k/(4*10^-4) >>> k = 160 N
P = 160/w^2
it said if she wears a heel with a width of .5 cm
P = 160(0.5 * 10^-2)^2 >>> P = 6400 KPa

A rug maker is using a pattern that is a rectangle with a length of 96 inches and a width of 60 inches. The rug maker wants to increase each dimension by a different amount. Let l and w be the increases in inches and the length and width. Write and simplify an expression for the perimeter of the new pattern.
Answers
Increasing the width by [tex]w[/tex], we have the new expression for the width as [tex]60+w[/tex]
Perimeter of a rectangle is given by adding all the sides, so we have
[tex]P = 96 + l+96+l+60+w+60+w[/tex]
[tex]P=192+2l+120+2w[/tex]
[tex]P = 312+2l+2w[/tex]

plz help i am on a quiz right now if i get it right i will mark the one who helped me the brainlyest answer
Answers
(rs)(4)=(2rootX)(rootX)
(rs)(4)=2x
(rs)(4)=8
(r/s)(3)=(2rootX)/(rootX)
(r/s)(3)=2
To evaluate (rs)(4) and (r/s)(3) for the given functions, substitute the value of x into the functions and calculate the product and quotient, respectively.
Explanation:To find (rs)(4), we need to substitute the value of x into the functions r(x) and s(x) and then find their product. r(x) = 2√x, so r(4) = 2√4 = 2√2 = 2(2) = 4. s(x) = √x, so s(4) = √4 = 2. Therefore, (rs)(4) = 4(2) = 8.
To find (r/s)(3), we need to substitute the value of x into the functions r(x) and s(x) and then find their quotient. r(3) = 2√3 and s(3) = √3. Therefore, (r/s)(3) = (2√3) / √3 = 2.

if 4 apples cost $3.04 how much does just one cost
Answers
So, we can assume all of the apples are the same price right? It doesn't matter about size or color because the problem doesn't tell us that. So, we can conclude one apple is the same prices as another.
Well, to figure out how much one apple costs, we can divide 3.04 by 4. This is because we have 4 apples so we can take that price of the 4 apples total and divide it by haw many apples the problem gives us.
So, 3.04 / 4 = .76

The cost C (in dollars) for the care and maintenance of a horse and carriage is C=15x+2000 where x is the number of rides.
Rides cost 35$
A: write an equation for the revenue R in terms of the number of rides
B: How many rides are needed to break even.
Need help with both parts
Answers
Answer: 100 rides are needed to break even.
Step-by-step explanation:
We have given the cost function
C(x)=15x+2000 where x is the number of rides.
And rides cost 35$
⇒ revenue function would be 35 times x
i.e.R(x)=35 x , where x is the number of rides.
Break even point of a firm occurs when at a certain point x the total cost equals to the total revenue.
i.e. at break even point
total revenue=total cost
⇒35x=15x+2000
⇒35-15x=2000[subtract 15x from both sides]
⇒20x=2000 [simplify]
⇒x=2000/20[dividing both sides with 20]
⇒x=100
∴ 100 rides are needed to break even.
The revenue function will be 35x and the breakeven point will be 100 rides.
From the information given, the revenue function will be calculated by multiplying the price by the quantity. This will be:
= 35 × x
= 35x
The breakeven point will be the point where total revenue equals the total cost. This will be:
35x = 15x + 2000
35x - 15x = 2000
20x = 2000
x = 2000/20
x = 100
Therefore, the revenue function will be 35x and the breakeven point will be 100 rides.

At a science competition, 25 problems were given. Each correct answer earned 4 points, and 2 points were deducted for each incorrect answer. No points were deducted for any unanswered problem. Logan answered all but one of the problems, receiving a score of 66. How many correct answers did Logan have?
Answers
x + y = 24 4x-2y = 66
since he only answered 24 questions
therefore max he can get is 96
x + y = 24
4x-2y = 66 from first equation,
y = 24-x plug that in second equation :
4x - 2(24-x) = 66
4x - 48 + 2x = 66
6x = 114
x = 19
Answer:
Correct answers of Logan is 19.
Step-by-step explanation:
Since, Logan didn't answered one problem.
Thus, total problem he attempt is 24.
Let the number of correct answer = x
and, Number of wrong answer = y
Then x + y = 24
And since it is given that,
He earned 4 points for correct answer and deduct 2 points for wrong answer. and he got score 66.
Thus we get equation,
4x - 2y = 66
Solving these two equation we get,
x = 19 and y = 6
Thus, Correct answers of Logan is 19.
factor -1/3 out of 1/3y-3/2
please help
Answers
When factoring, you are essentially dividing the GCF by all the terms.
So to factor out -1/3 from the binomial, we divided it all of the terms by -1/3:
First Term:
[tex]\frac{1}{3}y/-\frac{1}{3}[/tex]
[tex]=\frac{1}{3}y*-\frac{3}{1}[/tex]
[tex]=-3/3y[/tex]
[tex]=-1y[/tex]
Second Term:
[tex]=-\frac{3}{2} / - \frac{1}{3} [/tex]
[tex]=-\frac{3}{2} * - \frac{3}{1} [/tex]
[tex]=\frac{9}{2}[/tex]
The factored polynomial result would be:
[tex](-\frac{1}{3})(-1y+\frac{9}{2})[/tex]

To factor out -1/3 from 1/3y - 3/2, distribute the negative sign to both terms resulting in -1/9y + 1/2.
Explanation:To factor out -1/3 from the expression 1/3y - 3/2, we can distribute the negative sign to both terms. This results in -1/3(1/3y) + (-1/3)(-3/2). Simplifying this further, we get -1/9y + 1/2.

Find a polynomial function with real coefficients that has the given zeros. (There are many correct answers.) −5, −5, 1 + 2 i
Answers
Because complex zeros occur in conjugate pairs, the zeros are
-5, -5, 1 + 2i, 1 - 2i.
The polynomial is
f(x) = (x+5)²[x- (1+2i)][x -(1-2i)]
Note that
[x - (1+2i)][x - (1-2i)]
= x² - x(1 - 2i) - x(1+2i) + (1 - 4i²)
= x² - 2x +5
Therefore
f(x) = (x+5)²(x²-2x+5)
Answer: f(x) = (x+5)²(x²-2x+5)

Hopefully this example and explanation has helped you understand the concept of using the Distributive Property.
Now, let’s apply this to our current expression.
-8(5v - x - 5)
Remember that when you multiply a negative by a positive, the product remains negative. When you multiply a negative by a negative, the product is positive.
-8(5v - x - 5)
-8(5v) = -40v
-8(-x) = 8x
-8(-5) = 40
Our product is:

Solve the equation on the interval 0 ≤ θ < 2π.
1 - sin θ = 1/2
Answers
Final answer:
To solve the equation 1 - sin θ = 1/2 on the interval 0 ≤ θ < 2π, isolate the sine function and find the values of θ that satisfy the equation by taking the inverse sine of both sides. The solutions are θ = -π/6 and θ = 5π/6.
Explanation:
To solve the equation 1 - sin θ = 1/2 on the interval 0 ≤ θ < 2π, we can start by isolating the sine function. Subtracting 1/2 from both sides of the equation, we get -sin θ = -1/2. Next, we can find the values of θ that satisfy this equation on the given interval by taking the inverse sine (sin⁻¹) of both sides. This gives us θ = sin⁻¹(-1/2).
Using the unit circle or a calculator, we can find the values of θ that satisfy this equation. Let's first find the value of θ in the first quadrant. Here, sin θ = -1/2, so θ = sin⁻¹(-1/2) = -π/6.
Since we are looking for solutions on the interval 0 ≤ θ < 2π, we need to find the other solution that lies in the second quadrant. In the second quadrant, sin θ is also negative, but the angle is measured from the positive x-axis in the clockwise direction. Therefore, θ = -π + π/6 = 5π/6 is the other solution.
Final answer:
To solve the equation 1 - sin θ = 1/2 on the interval 0 ≤ θ < 2π, you can isolate the sine function and apply the inverse sine function to find the solutions.
Explanation:
To solve the equation 1 - sin θ = 1/2 on the interval 0 ≤ θ < 2π, we can start by isolating the sine function. Subtracting 1/2 from both sides of the equation, we get -sin θ = -1/2.
Next, we can apply the inverse sine function to both sides. This will give us two possible values for θ within the given interval: θ = π/6 and θ = 5π/6.
Therefore, the solutions to the equation 1 - sin θ = 1/2 on the interval 0 ≤ θ < 2π are θ = π/6 and θ = 5π/6.
