Answers
Note that where the above function is given, the equation in function notation is f(x) = (-2/3)x + 490. This function represents the profit Sal makes from lunch specials based on the number of sandwich and wrap lunch specials sold. See the graph attached.
What is the explanation for the above response?To change the given equation to slope-intercept form, we need to solve for y.
2x + 3y = 1470
3y = -2x + 1470
y = (-2/3)x + 490
Therefore, the slope of the line is -2/3 and the y-intercept is 490.
To graph this line using the slope-intercept method, we can plot the y-intercept first, which is (0, 490). Then, using the slope of -2/3, we can find another point by moving 2 units to the right and 3 units down from the first point. We can continue this pattern to plot additional points and then draw a straight line through them.
The equation in function notation is f(x) = (-2/3)x + 490. This function represents the profit Sal makes from lunch specials based on the number of sandwich and wrap lunch specials sold.
To graph the function, we can plot the intercepts (0, 490) and (735, 0), where 735 is the x-intercept. Then, using the slope of -2/3, we can find other points and draw a straight line through them.
If Sal's total profit on lunch specials for the next month is $1,593, then the equation would be 2x + 3y = 1593. The graphs of the functions for both months would have the same slope of -2/3, indicating that the profit per lunch special sold remains constant.
However, the y-intercept would be different, indicating a different starting profit for the month. The graphs would have different intercepts and intersect the y-axis at different points, reflecting the difference in starting profits.

What is the volume of a solid?The volume of a solid in geometry signifies the space it occupies inside a three-dimensional area. It denotes how much content can fill up its inner region, and as usual, measured in units like cubic feet, meters, or centimeters.
Finding the measurement formula varies from shape to shape but commonly involves multiplying width, height, and length. Given that many sectors rely on this term, such as engineering, architecture, and physics, understanding the concept of the volume of a solid weighs significantly.
If we take a cross-section of (x,y)perpendicular to the x-axis, with width dx, now the cross-section is a quarter circle with radius y.
Thus, the volume of the cross-section, since y = 2x becomes: [tex]\pi x^2 dx[/tex]
Now, the volume of the solid when integrated becomes: [tex]\frac{\pi }{3}[/tex]

a driveway consists of two rectangles one rectangle is 80 ft long and 15 ft wide the other is 30 ft long and 30 ft wide what is the area of the driveway
Answers
Answer: 2100 square feet
Step-by-step explanation:
To solve this question we must add the areas of the two rectangles.
area = length x width
Rect 1:
a = lw
= 80 x 15 = 1200 square feet
Rect 2:
a = lw
= 30 x 30 = 900 square feet
so in total, the driveway is 1200 + 900 = 2100 square feet
Answer:
To find the area of the driveway, we need to find the area of both rectangles and add them together.
The area of the first rectangle is:
80 ft x 15 ft = 1200 sq ft
The area of the second rectangle is:
30 ft x 30 ft = 900 sq ft
To find the total area of the driveway, we add the two areas together:
1200 sq ft + 900 sq ft = 2100 sq ft
Therefore, the area of the driveway is 2100 square feet.

The value of the integral [tex]\int -1^1 (13 - 12) dt[/tex] is 26.
How to evaluate the integral?To evaluate the integral [tex]\int-1^1 (13 - 12) dt[/tex] , we need to find an antiderivative of the integrand, which is simply:
∫ (13 - 12) dt = 13t - 12
Using this antiderivative, we can evaluate the definite integral by applying the theorem:
[tex]\int-1^1 (13 - 12) dt = [13t - 12]_{(-1)^1[/tex]
Evaluating this expression at the limits of integration (-1 and 1), we get:
[13(1) - 12] - [13(-1) - 12]

Answers
The best estimate for the volume of the tank in cubic feet is 5.5 cubic feet.
The volume of the tank is:
V = l x w x h
where l is the length, w is the width, and h is the height.
Substituting the given values, we get:
V = 25 x 34.5 x 11 = 9547.5 cubic inches
To convert cubic inches to cubic feet, we divide by (12 x 12 x 12), since there are 12 inches in a foot and 12 x 12 x 12 cubic inches in a cubic foot:
V = 9547.5 / (12 x 12 x 12) cubic feet
V ≈ 5.5 cubic feet
Therefore, 5.5 cubic feet is the best estimate for the tank's cubic foot capacity.
Hence , the volume of the rectangular glass tank is 5.490 feet³

A restaurant in Richmond, BC, lists the prices on its menus in fractions of a dollar. Three friends have lunch at the restaurant. Each of 3 friends orders a veggie mushroom cheddar burger for 11 % ( , with a glass of water to drink.
What was the total bill be fore taxes, in fractions of a dollar?
Answers
If each of the 3 friends orders a veggie mushroom cheddar burger for 11%, the cost of each burger would be:
11% of $1.00 = $0.11
Since the prices are listed in fractions of a dollar, we can express the cost of each burger as 11/100 of a dollar.
So, the total cost of 3 veggie mushroom cheddar burgers would be:
3 x 11/100 = 33/100 = $0.33
Assuming that the glass of water is free, the total bill before taxes would be $0.33 for the 3 burgers. However, it's important to note that this calculation is based on the assumption that the prices are listed in fractions of a dollar, which may not be the case. If the prices are listed in a different unit, the calculation would need to be adjusted accordingly.

Use Newton's method to approximate a root of the equation In (4x) = arctan(x -0.1) as follows. Let x1 = 0.1 be the initial approximation. The fourth approximation x4 is and the fifth approximation x5 is
Answers
To use Newton's method to approximate a root of the equation
In (4x) = arctan(x -0.1),
we will need to find the first derivative of the function f(x) = In(4x) - arctan(x-0.1). f(x) = In(4x) - arctan(x-0.1) f'(x) = 4/(4x) - 1/(1+(x-0.1)^2) Using the initial approximation x1 = 0.1,
We can find the second approximation x2: x2 = x1 - f(x1)/f'(x1) x2 = 0.1 - [In(4*0.1) - arctan(0.1-0.1)] / [4/(4*0.1) - 1/(1+(0.1-0.1)^2)] x2 = 0.1076
We can repeat this process to find the third approximation x3: x3 = x2 - f(x2)/f'(x2) x3 = 0.1076 - [In(4*0.1076) - arctan(0.1076-0.1)] / [4/(4*0.1076) - 1/(1+(0.1076-0.1)^2)] x3 = 0.1078
Now we can find the fourth approximation x4: x4 = x3 - f(x3)/f'(x3) x4 = 0.1078 - [In(4*0.1078) - arctan(0.1078-0.1)] / [4/(4*0.1078) - 1/(1+(0.1078-0.1)^2)] x4 = 0.1078
Finally, we can find the fifth approximation x5: x5 = x4 - f(x4)/f'(x4) x5 = 0.1078 - [In(4*0.1078) - arctan(0.1078-0.1)] / [4/(4*0.1078) - 1/(1+(0.1078-0.1)^2)] x5 = 0.1078

How to find a unit vector that satisfies the given conditions?To find a unit vector that is oppositely directed to v = (3, -4) and half its length, we can follow these steps:
Find the length of vector v:
|v| = sqrt(3^2 + (-4)^2) = 5
Divide vector v by 2 to get a vector with half its length:
v/2 = (3/2, -2)
To get a vector that is oppositely directed to v, we can reverse the direction of v/2:
-(3/2, -2) = (-3/2, 2)
Finally, we can find the unit vector in the direction of (-3/2, 2) by dividing it by its length:
|(-3/2, 2)| = sqrt((-3/2)^2 + 2^2) = sqrt(13/4)
u = (-3/2, 2) / sqrt(13/4) = (-3/2) * (2/sqrt(13))/2 + (2/sqrt(13)) * (1/2)

PLEASEEE
Answers
Paul and Marlena should deposit approximately $2,431.23 into an account now to have enough for their cruise in ten years.
So, the correct answer is B. $2,431.23.
To calculate the amount Paul and Marlena should deposit into an account now in order to have enough for their cruise in ten years, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^{ (nt)}[/tex]
Where:
A = the future value of the investment/loan, including interest
P = the principal amount (initial deposit)
r = the annual interest rate (in decimal form)
n = the number of times that interest is compounded per year
t = the number of years
In this case, the principal amount (P) is what we need to find.
The future value (A) is given as $5,800.
The interest rate (r) is 5.3% or 0.053 as a decimal.
The interest is compounded daily, so n = 365 (number of days in a year).
Using the formula, we can rearrange it to solve for P:
[tex]P = A / (1 + r/n)^{(nt)[/tex]
Substituting the given values:
[tex]P = 5800 / (1 + 0.053/365)^{(365\times 10)[/tex]
Calculating this expression:
P ≈ 2,431.23

Chandler earns $15.25 an hour as a hostess at a local restaurant. She
earns an additional $25 in tips each night from take-out orders.
Determine if this linear relationship is proportional. Explain.
Answers
No, this linear relationship is not proportional, because the ratio between Chandler's hourly wage and tips changes because the number of hours worked changes
Proportional relationships are those wherein the ratio between the two portions being as compared stays constant, no matter the values of those quantities.
In this case, we're evaluating Chandler's earnings primarily based on her hourly wage and her hints from take-out orders.
But, the ratio between Chandler's hourly wage of $15.25 and her tips of $25 per night varies relying on the number of hours she works.
For example, if Chandler works for 2 hours, her total income could be $30.50 (2 x $15.25) + $25 = $55.50.
If she works for four hours, her total earnings would be $61 (4 x $15.25) + $25 = $86. In this example, the ratio among her hourly salary and tips adjustments as her income increase with more hours worked.
Therefore, because the ratio between Chandler's hourly wage and tips changes because the number of hours worked changes, this linear relationship is not proportional.

Answers
The histogram for the frequency table is illustrated below.
To create the frequency table, we need to count how many times each time appears in the data set. The time 9:23 appears twice, so we would put a frequency of 2 in the row corresponding to 9:23. We do this for each time in the data set.
Here is the completed frequency table:
Time Frequency

9:01 1
9:14 1
9:15 1
9:18 1
9:23 2
As you can see, each time appears only once or twice in the data set. This tells us that there is no dominant time that most students ran the mile in.
To create the histogram, we'll draw a bar above each time on the x-axis with a height equal to the frequency of that time. For example, there are two times of 9:23, so we'll draw a bar above 9:23 with a height of 2.

Which equation represents the volume of each cone?
Answers
The equation which represents the volume of each cone is as follows:
V = (1/3)πr²h
Explanation :
In this equation, "V" represents the volume of the cone, "r" represents the radius of the base, and "h" represents the height of the cone.
V represents the volume of the cone. Volume is a measure of the space occupied by an object, and in this case, it refers to the space inside the cone.
π (pi) is a mathematical constant approximately equal to 3.14159. It is used in calculations involving circles and spheres.
r represents the radius of the base of the cone. The radius is the distance from the center of the base to any point on its circumference. Squaring the radius, r², gives us the area of the base.
h represents the height of the cone. It is the perpendicular distance from the base to the vertex (top) of the cone.
When we multiply the area of the base (πr²) by the height (h) and divide the result by 3, we get the volume of the cone. The division by 3 is necessary because the volume of a cone is one-third the volume of a cylinder with the same base and height.
So, the equation V = (1/3)πr²h provides a way to calculate the volume of a cone based on its radius and height.

a) how long does janets journey take?
(b) how much longer does andrew spend driving than janeta
Answers
1) Bona can drive 108 miles if she drove for 3 hour at the same speed as Claire.
2) Janet would take 1.5 hour to complete the journey and Andrew spend half hour more driving than Janet.
1) Bona speed is 44mph
Time taken by Bona is 3 hour
distance travelled by Claire is 144 miles
Time taken by Claire is 4 hour
Claire's speed = distance / time
Claire's speed = 144/4
Claire's speed = 36 mph
Distance travelled by Bona = speed × time
Distance travelled by Bona = 36 × 3
Distance travelled by Bona = 108 miles
2) Janet distance = 60 miles
Janet speed = 40 mph
Time taken by Janet = distance / speed
Time taken by Janet = 60/40
Time taken by Janet = 1.5 hour
Janet would take 1.5 hour to complete the journey
Andrew distance = 80 miles
Andrew speed = 40 mph
Time taken by Andrew = distance / speed
Time taken by Andrew = 80/40
Time taken by Andrew= 2 hour
Andrew spend half hour more driving than Janet.

The measure of arc a must be 2 times measure of inscribed angle, which is 90 degrees.
What is arc?
In geometry, an arc is a segment of a circle's circumference. It is defined by two endpoints and all the points on the circle's circumference between them.
What is inscribed angle?
An inscribed angle is an angle formed by two chords in a circle that have a common endpoint.
According to given information:For any inscribed angle in a circle, the measure of the angle is always half the measure of the arc that it intercepts. This is known as the inscribed angle theorem.
So, if we have an inscribed angle with a measure of 45 degrees, then the measure of its corresponding arc would be 2 times that, which is 90 degrees.
Therefore, if the inscribed angle is associated with arc a, and the measure of the corresponding angle is 45 degrees, then we know that the measure of arc a must be 2 times that, which is 90 degrees.

The average weight of Carl, Carla, Carmen, Clark, and Cathy is 107.6 lb. Cathy weighs 115 lb. What is the average weight of the other four? Show your work.
Answers
Answer:
Step-by-step explanation:
Let's start by finding the total weight of all five people:
Total weight = Average weight x Number of people
Total weight = 107.6 x 5
Total weight = 538
We know that Cathy weighs 115 lb, so we can subtract her weight from the total weight to find the total weight of the other four people:
Total weight of other four = Total weight - Cathy's weight
Total weight of other four = 538 - 115
Total weight of other four = 423
To find the average weight of the other four, we can divide the total weight of the other four by the number of people:
Average weight of other four = Total weight of other four / Number of people
Average weight of other four = 423 / 4
Average weight of other four = 105.75 lb
Therefore, the average weight of the other four is 105.75 lb.

What are the coordinates of the point on the directed line segment from (-3,-5) to (9,−8) that partitions the segment into a ratio of 2 to 1?
Answers
The coordinates of the point are (7,0).
How to solve for the coordinatesdistance from (-3,-5) to (x,y) = 2 * distance from (x,y) to (9,-8)
Using the distance formula, we can write this equation as:
√[(x - (-3))^2 + (y - (-5))^2] = 2 * √[(9 - x)^2 + (-8 - y)^2]
Simplifying this equation, we get:
[tex](x + 3)^2 + (y + 5)^2 = 4[(9 - x)^2 + (-8 - y)^2][/tex]
Expanding and simplifying further, we get:
[tex]17x + 16y = 119[/tex]
So the coordinates of the point on the directed line segment from (-3,-5) to (9,-8) that partitions the segment into a ratio of 2 to 1 are:
x = (119 - 16y)/17
y = any value (since we can choose any value of y and then calculate x using the equation above)
For example, if we choose y = 0, then we get:
x = (119 - 16(0))/17 = 7
So the coordinates of the point are (7,0).
