Marshall is renting a bike for the day. It costs $13 for up to one hour. After one hour, the price increases to $20. After three hours, the price increases again to $50. The maximum time he can rent the bike is 10 hours total
The piecewise function that represents the situation is therefore:
Costs Possible hours
13 0 < x ≤ 1
20 1 < x ≤ 3
50 3 < x ≤ 10
How to find the piecewise function ?We see that up to one hour, the cost to Marshall would be $ 13 so the possible hours at that price is 0 < x ≤ 1 .
Likewise from one hour, the price goes up to $ 20 which means that possible hours become 1 < x ≤ 3 because the price will increase at 3 hours again.
From 3 hours, the price becomes $ 50 and there are a maximum of 10 hours so the hours become 3 < x ≤ 10 .

I need help with this question.
Answer: The answer is (C
Step-by-step explanation:
FRACTIONS It is John's birthday and his mother decided to give him a birthday party. She bought him three cakes for his party; cake one was sliced into 8 pieces, cake two was sliced into 10 pieces, and cake three was sliced into 12 pieces. If the guests at the party ate 4 slices of cake one, 7 slices of cake two and 5 slices of cake three; calculate the amount of cake that was eaten in total.
There are 30 slices in total, so our denominator would be 30.
Now we simply have to add 4, 7 and 5. The answer to this would be 16.
So the amount of cake eaten in total is 16/30.
If your assignment is for improper fractions, I'm guessing the answer would be 16/3 instead.
Answer:
1 37/60 cakes
Step-by-step explanation:
You want the total cake eaten if 4 of 8 slices, 7 of 10 slices, and 5 of 12 slices were eaten.
SumThe sum of the three fractions is ...
4/8 +7/10 +5/12
= 5/10 +7/10 +5/12 . . . . . . . 4/8 = 1/2 = 5/10
= 12/10 +5/12
= 6/5 +5/12
= (6·12 +5·5)/(5·12) = 97/60 = 1 37/60
The total amount of cake that was eaten was equivalent to 1 37/60 cakes.

Solve the given differential equation 3 4ydx - 4xdy + x³dx = 7dx The solution is= (Type an equation.)
The solution of the given differential equation is y = x + Cx⁴ - x²/4, where C is a constant.
We begin by rearranging the terms as follows:
(4y + x³ - 7)dx = (4x)dy
Integrating both sides, we get:
4xy + (1/4)x⁴ - 7x = 2y² + C
where C is the constant of integration.
Next, we can rearrange this equation to solve for y:
y² = 2xy + (1/8)x⁴ - (7/2)x - C/2
y² - 2xy = (1/8)x⁴ - (7/2)x - C/2
We can complete the square to obtain a more useful expression:
(y - x)² = (1/8)x⁴ - (7/2)x - C/2 + x²
y - x = ±sqrt((1/8)x⁴ - (7/2)x - C/2 + x²)
Simplifying this expression, we get:
y = x ±sqrt(Cx⁴ - (1/4)x⁴ + 7x - C)
Taking the positive sign for simplicity, we get the final solution as:
y = x + sqrt(Cx⁴ - (1/4)x⁴ + 7x - C)
where C is the constant of integration.
We can also simplify this solution further by using the identity (a + b)² = a² + 2ab + b² to get:
y = x + Cx⁴ - x²/4
where C is a constant, as desired.

(a) if f(4) = 6, what is f-|(6)? f-'(6) = (b) Suppose a function can be described by y = f(x). The function and its inverse intersect when y = (c) Consider a linear function f (x) = ax + b where a 70. Is the inverse of this linear function always a linear function? (No answer given) If f(x) = ax + b and a € 0, then f-'(x) =
To find f-1(6), we need to find the value of x that gives f(x) = 6. However, we don't have enough information about the function f to do this. We need to know whether f is a linear function or not.
When the function and its inverse intersect, we have f(x) = f-1(x). Substituting y for both f(x) and f-1(x), we get y = f(y). To find the value of y when this is true, we need to solve for y:
y = f(y)
y = f-1(y)
Substituting y = f(x), we get:
f(x) = f-1(f(x))
f(x) = x
So the function and its inverse intersect when y = x.
If a = 0, then the linear function is f(x) = b, which is a constant function. Constant functions do not have inverses, so the inverse of f(x) = b does not exist.
If a ≠ 0, then the inverse of f(x) = ax + b is given by:
f-'(x) = (x - b) / a
This is also a linear function, so the inverse of a linear function is always a linear function when a ≠ 0.
(a) To find the inverse of a linear function, you need to swap the x and y values. Given that f(4) = 6, the inverse function f^(-1)(6) would yield the value of x when y = 6. Since we know that f(4) = 6, it implies that f^(-1)(6) = 4.
A function and its inverse intersect when the input value (x) is equal to the output value (y). In other words, they intersect when y = x.
(c) Yes, the inverse of a linear function is always a linear function. If f(x) = ax + b, where a ≠ 0, then the inverse function, f^(-1)(x), can be found by swapping x and y values and solving for y. In this case, x = ay + b. Solving for y, we get y = (x - b) / a, which is also a linear function.

write an equation of the line that passes through each pair of points (5, 7), (-8, -4)
Answer:
y = 11x/13 + 36/13
Step-by-step explanation:
We can write the line using y = mx + b form.
To find the slope, m, we can use the formula (y1 - y2) / (x1 - x2):
(7-(-4)) / (5-(-8)) = (7+4) / (5+8) = 11 / 13.
To find b, we can plug in one of the points. Lets use (5, 7).
y = 11/13 * x + b
7 = 11/13 * 5 + b
7 - 55/13 = b
b = 91/13 - 55/13 = (91-55)/13 = 36/13.
Your equation is:
y = 11x/13 + 36/13.
Answer: y = [tex]\frac{11}{13}[/tex]x + [tex]\frac{36}{13}[/tex]
Step-by-step explanation:
First, we will find the slope.
[tex]m=\displaystyle \frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{-4-7}{-8-5} =\frac{-11}{-13} =\frac{11}{13}[/tex]
Next, we will substitute this slope and a given point in and solve for our y-intercept (b).
y = [tex]\frac{11}{13}[/tex]x + b
(7) = [tex]\frac{11}{13}[/tex](5) + b
(7) = [tex]\frac{11}{13}[/tex](5) + b
7 = [tex]\frac{55}{13}[/tex] + b
b = 7 - [tex]\frac{55}{13}[/tex]
b = [tex]\frac{36}{13}[/tex]
Final equation:
y = mx + b
y = [tex]\frac{11}{13}[/tex]x + [tex]\frac{36}{13}[/tex]

Joshua's mail truck travels 14 miles every day he works
and is not used at all on days he does not work. At the
end of his 100th day of work the mail truck shows a
mileage of 76,762. Model Joshua's truck mileage as a
function of the number of days he has worked. When
will he reach 100,000 miles?
Solving the equation, Joshua will reach 100,000 miles after approximately 1,760 days of work.
To model Joshua's truck mileage as a function of the number of days he has worked, we can use the following equation:
Mileage (M) = 14 * Number of days worked (D) + Initial Mileage (I)
First, we need to determine the initial mileage on the mail truck. To do this, we can use the information given for his 100th day of work:
76,762 = 14 * 100 + Initial Mileage
76,762 = 1,400 + Initial Mileage
Initial Mileage (I) = 76,762 - 1,400
Initial Mileage (I) = 75,362
Now we can rewrite the equation as:
Mileage (M) = 14 * Number of days worked (D) + 75,362
To find when Joshua will reach 100,000 miles, we can set M equal to 100,000 and solve for D:
100,000 = 14 * D + 75,362
24,638 = 14 * D
D ≈ 24,638 / 14
D ≈ 1,759.857
Since Joshua cannot work a fraction of a day, he will reach 100,000 miles after approximately 1,760 days of work.

In δmno, m = 540 inches, n = 330 inches and o=600 inches. find the measure of ∠o to the nearest 10th of a degree
The measure of ∠O in ΔMNO is approximately 41.5°.
To find the measure of ∠O, we can use the Law of Cosines in ΔMNO, with sides M = 540 inches, N = 330 inches, and O = 600 inches. The Law of Cosines states:
O² = M² + N² - 2MN * cos(∠O)
Rearrange the equation to solve for cos(∠O):
cos(∠O) = (M² + N² - O²) / (2MN)
Substitute the values:
cos(∠O) = (540² + 330² - 600²) / (2 * 540 * 330)
cos(∠O) ≈ -0.7944
Now, find the angle using the inverse cosine function:
∠O ≈ arccos(-0.7944) ≈ 141.5°
Since ∠O is an obtuse angle, we need to find its supplement to the nearest 10th:
180° - 141.5° ≈ 38.5°
Thus, the measure of ∠O is approximately 38.5°.

Determine the common ratio for each of the following geometric series and determine which ones have an infinite sum
The common ratio for the geometric series 1, 1/2, 1/4, 1/8, ... is 1/2 and the sum of series is 2 which is finite.
To determine whether the series has an infinite sum, we can use the formula for the sum of an infinite geometric series, which is:
S = a/(1-r),
where a is the first term and r is the common ratio.
In this case, a = 1 and r = 1/2, so
S = 1/(1 - 1/2) = 2.
Since the value of S is finite and not infinite, we can conclude that the given geometric series has a finite sum of 2.
The common ratio of a geometric series is the ratio between consecutive terms. For example, in the series 1, 2, 4, 8, 16, ..., the common ratio is 2 because each term is obtained by multiplying the previous term by 2.
To determine whether a geometric series has an infinite sum, we can use the formula for the sum of an infinite geometric series, which is S = a/(1-r), where a is the first term and r is the common ratio.
If the value of r is between -1 and 1 (excluding -1), then the series has a finite sum. If the value of r is greater than 1 or less than -1, then the series has an infinite sum.
In the given series 1, 1/2, 1/4, 1/8, ..., the common ratio is 1/2. To find the sum of the series, we can use the formula S = a/(1-r) with a=1 and r=1/2, which gives S=2. Since the value of S is finite and not infinite, we can conclude that the given geometric series has a finite sum of 2.

Molly's cafe has regular coffee and decaffeinated coffee. this morning, the cafe served 30 coffees in all, 40% of which were regular. how many regular coffees did the cafe serve?
The cafe served 12 regular coffees.
Out of the 30 coffees served at Molly's cafe this morning, 40% were regular coffee. To determine the number of regular coffees, we can calculate 40% of 30.
To find the value,
Step 1: Convert the percentage to a decimal by dividing it by 100. So, 40% = 40/100 = 0.4.
Step 2: Multiply the total number of coffees served by the decimal. So, 30 * 0.4 = 12.
Hence, the cafe served 12 regular coffees. The remaining 60% (or 18 coffees) would be decaffeinated. It is important to note that percentages represent proportions or fractions of a whole. In this case, 40% indicates that 40 out of 100 parts (or 40/100) are regular coffees. By applying this proportion to the total number of coffees served (30), we can determine the specific quantity. This method can be used in various scenarios involving percentages to find a portion of a whole. Therefore, Molly's cafe served 12 regular coffees and 18 decaffeinated coffees, making a total of 30 coffees.
Your answer: Molly's cafe served 12 regular coffees this morning.

Find the coordinates of the points on the curve x(????)=3????^2 +1 ????????????y(????)=????^3 −1, for which the tangent linehas a slope of 1/2
The coordinates of the point on the curve where the tangent line has a slope of 1/2 are (4, 0).
To find the coordinates of the points on the curve x(t) = 3t^2 + 1 and y(t) = t^3 - 1, where the tangent line has a slope of 1/2, follow these steps:
1. Calculate the derivatives of x(t) and y(t) with respect to t:
dx/dt = 6t
dy/dt = 3t^2
2. The slope of the tangent line is given by dy/dx, so calculate dy/dx using the chain rule:
dy/dx = (dy/dt) / (dx/dt) = (3t^2) / (6t) = t/2
3. Set the slope equal to 1/2 and solve for t:
t/2 = 1/2
t = 1
4. Plug the value of t back into the original equations for x(t) and y(t) to find the coordinates of the point:
x(1) = 3(1)^2 + 1 = 4
y(1) = (1)^3 - 1 = 0
The coordinates of the point on the curve where the tangent line has a slope of 1/2 are (4, 0).

When the price of a certain product is $40, 25 items can be sold. When the price of the same
product costs $20, 185 items can be sold. On the other hand, when the price of this product
is $40, 200 items will be produced. But when the price of this product is $20, only 100 items
will be produced. Use this information to find supply and demand functions (assume for
simplicity that the functions are linear), and compute the consumer and producer surplus at
the equilibrium price
Based on the information, the equilibrium price is $56.67
How to calculate the equillbriumUsing the first data point, we have:
25 = a - 40b
Using the second data point, we have:
185 = a - 20b
Solving these two equations simultaneously, we get:
a = 325
b = 5/2
So the demand function is:
Qd = 325 - 5/2 P
the supply function is:
Qs = -100 + 5P
325 - 5/2 P = -100 + 5P
425 = 15/2 P
P = $56.67

The slope of the tangent line to the function [tex]s(t) = 8 - 41t^2[/tex] at t = -3 is 246.
Process of finding slope:1. Differentiate the function s(t) with respect to the independent variable t: [tex]s(t) = 8 - 41t^2[/tex].
2. Calculate the derivative s'(t).
3. Evaluate the derivative at the given value of t.
Step 1: Differentiate the function [tex]s(t) = 8 - 41t^2[/tex].
To differentiate this function, we apply the power rule for differentiation.
The derivative of a constant (8) is 0, and the derivative of 41t^2 is -82t
(since we multiply the exponent 2 by the coefficient 41 and then subtract 1 from the exponent).
Step 2: Calculate the derivative s'(t).
s'(t) = 0 - 82t
Step 3: Evaluate the derivative at the given value of t (t = -3).
s'(-3) = -82(-3) = 246
The slope of the tangent line to the function [tex]s(t) = 8 - 41t^2[/tex] at t = -3 is 246.

A force of 80 pounds on a rope is used to pull a box up a ramp inclined at 10 degrees from the horizontal. The rope forms an angle of 33 degrees with the horizontal. How much work is done pulling the box 26 feet along the ramp?
The work done on the displacement is 301.95J
What is the work done in pulling the boxTo determine the work done, we need to find the displacement in which the box moved.
cos θ = adjacent / hypothenuse
cos 33 = adjacent / 80
adjacent = 80 * cos 33
adjacent = 67.1 lbs
The force applied is 67.1lbs
The displacement on the ramp;
sin θ = opposite / hypothenuse
sin 10 = opposite / 26
opposite = 26 * sin 10
opposite = 4.5 ft
The work done in moving the object can be calculated as;
work done = force * displacement
work done = 67.1 * 4.5
work done = 301.95 J

Answer the following:
Myla bought an item P2,500. She decided to sell it wil 2% markup. How much will Myla’s selling price be?
Joan sold her old iphone for P5000 at 8% markdown rate. Find the markdown and the original cost of the phone.
A student assistant bought an item for P520 but later decided to sell it at P550. What is the markup?
Mother organize a garage sale and earned P120 on one item at 60% markdown. How much did mother buy the item?
The cost of a t-sirt from the manufacturer is P400. If loan wants a 30% markup based on the selling price, how much will her selling price be?
1. Myla bought an item for P2,500 and decided to sell it with a 2% markup. The selling price will be P2,500 + (2% of P2,500) = P2,500 + P50 = P2,550.
2. Joan sold her old iPhone for P5,000 at an 8% markdown rate. To find the markdown and the original cost, we first calculate the markdown: P5,000 = 92% of original price. So, the original price was P5,000 ÷ 0.92 ≈ P5,434.78. The markdown is P5,434.78 - P5,000 = P434.78.
3. The student assistant bought an item for P520 and sold it for P550. The markup is P550 - P520 = P30.
4. Mother earned P120 on an item at a 60% markdown. Let X be the original price, then X * 60% = P120. X = P120 ÷ 0.60 = P200. So, the mother bought the item for P200.
5. The cost of a t-shirt from the manufacturer is P400. If Loan wants a 30% markup based on the selling price, we'll let X be the selling price, then X - 30% of X = P400. So, 0.7X = P400. X = P400 ÷ 0.7 ≈ P571.43. Loan's selling price will be P571.43.

Stephanie throws a paper airplane off the roof of her school. Her classmates measure the plane’s height, in feet, after each second. The table shows some of her data.
T= 0, 1, 2, 3, 4
h(t)= 200, 208, 212, 212, 208
Find the equation for h(t), and use it to determine how long it will take the plane to hit the ground. Round to the nearest hundredth
The paper airplane will not hit the ground within the given time frame.
To find the equation for h( t), we need to find the rate of change or the pitch of the function. We can do this by chancing the difference in height and time for any two points on the line. Let's choose the first two points,( 0,200) and( 1,208).
pitch = ( change in height)/( change in time)
pitch = ( 208- 200)/( 1- 0) = 8
So, the equation for h( t) can be written in pitch- intercept form as h( t) = 8t b
To find the value of b, we can use any of the given points.
Let's use( 0,200) 200 = 8( 0) b b = 200
So, the equation for h( t) is h( t) = 8t 200
To find how long it'll take the aeroplane to hit the ground, we need to find when h( t) = 0,
since that would mean the height is 0 bases or the ground position. 0 = 8t 200 working for t,
we get t = -25
Since time cannot be negative the paper airplane will not hit the ground within the given time frame.
