A left the work after 3 days was solved by using work formula.
What is algebraic equation?An algebraic equation is a mathematical statement that asserts that two expressions are equal. These expressions can contain variables, which are represented by letters, and the equation states that the values of the expressions are equal for some particular values of the variables.
What is work formula?The work formula is a mathematical concept used to determine how long it will take two or more workers to complete a job together. The formula is based on the idea that the amount of work done is directly proportional to the time spent working.
In the given question,
Let's assume that A worked for x days, and therefore he left the work unfinished for (15 - x) days. During this time, B finished the remaining work in 7 days.
According to the work formula, the amount of work done by A and B together in one day is:
1/15 + 1/18 = 11/90
This means that in one day, they can complete 11/90th of the work together.
During the x days when A worked, the amount of work he did is:
x * (11/90)
And during the remaining (15 - x) days, the amount of work left undone is:
(15 - x) * (11/90)
When A left, B completed the remaining work in 7 days, so we can set up an equation:
(11/90) * 7 = (15 - x) * (11/90)
Simplifying and solving for x, we get:
x = 3
Therefore, A left the work after 3 days.

Oliver spots an airplane on radar that is currently approaching in a straight line, and
that will fly directly overhead. The plane maintains a constant altitude of 6900 feet.
Oliver initially measures an angle of elevation of 16° to the plane at point A. At some
later time, he measures an angle of elevation of 27° to the plane at point B. Find the
distance the plane traveled from point A to point B. Round your answer to the
nearest tenth of a foot if necessary.
The distance the plane traveled from point A to point B is approximately 8.15 miles or 43056 feet (rounded to the nearest tenth of a foot).
What are angles?An angle is a geometric figure formed by two rays, called the sides of the angle, that share a common endpoint, called the vertex of the angle. Angles are typically measured in degrees or radians, and they are used to describe the amount of rotation or turning between two lines or planes. In a two-dimensional plane, angles are usually measured as the amount of rotation required to move one line or plane to coincide with the other line or plane.
Let's first draw a diagram to visualize the problem:

d
We need to find the distance the plane traveled from point A to point B, which we'll call d. We can use trigonometry to solve for d.
From point A, we have an angle of elevation of 16° to the plane. This means that the angle between the horizontal and the line from point A to the plane is 90° - 16° = 74°. Similarly, from point B, we have an angle of elevation of 27° to the plane, so the angle between the horizontal and the line from point B to the plane is 90° - 27° = 63°.
Let's use the tangent function to solve for d:
x = h / tan(74°) = 19906.5 ft
d - x = h / tan(63°) = 23205.2 ft
So,
d = x + h / tan(63°) ≈ 43111.7 ft ≈ 8.15 miles.
Therefore, the distance the plane travelled from point A to point B is approximately 8.15 miles or 43056 feet (rounded to the nearest tenth of a foot).

How does the graph of g(x) = (x + 2)3 − 6 compare to the parent function of f(x) = x3? g(x) is shifted 2 units to the right and 6 units down. g(x) is shifted 6 units to the right and 2 units up. g(x) is shifted 2 units to the left and 6 units down. g(x) is shifted 6 units to the left and 2 units down.
Answer:
The function g(x) = (x + 2)³ − 6 is obtained by applying three transformations to the parent function f(x) = x³.
First, g(x) is shifted 2 units to the left by subtracting 2 from x inside the parentheses:
g(x) = (x + 2 - 2)³ − 6 = (x)³ − 6
This shows that option C, "g(x) is shifted 2 units to the left and 6 units down," is not correct.
Next, g(x) is shifted 6 units down by subtracting 6 from the entire function:
g(x) = (x + 2)³ − 6 - 6 = (x + 2)³ - 12
This shows that option A, "g(x) is shifted 2 units to the right and 6 units down," is correct.
Finally, g(x) is not shifted left or right by any additional units, but it is shifted 2 units up by adding 2 to the constant term:
g(x) = (x + 2)³ − 6 + 2 = (x + 2)³ - 4
This shows that option B, "g(x) is shifted 6 units to the right and 2 units up," is not correct.
Therefore, the correct answer is option A: g(x) is shifted 2 units to the right and 6 units down.

Which of the following equations will reduce the graph shown below
The equation y = -1/2(x-3)² + 5 reduces the graph, which means that the graph decreases as we move away from the vertex (3, 5) in both directions along the x-axis.
What is graph?In mathematics, a graph is a visual representation of a set of objects (called vertices or nodes) and the connections (called edges) between them.
The equation y = -1/2(x-3)² + 5 is a quadratic function in vertex form. The vertex of this parabola is at the point (3, 5), and the coefficient of the x² term is negative (-1/2), which tells us that the parabola opens downwards. This means that the graph of this equation reduces.
To see why this is the case, consider the behavior of the y-values as x moves away from the vertex. Since the leading coefficient is negative, the y-values will decrease as x moves to the left or right from the vertex. Additionally, the squared term inside the parentheses means that the graph will be symmetric around the x-coordinate of the vertex, which is 3 in this case.
Thus, as x moves away from the vertex to the left or right, the y-values decrease in a symmetric manner, resulting in a graph that reduces. This can be seen in the shape of the parabola as it curves downwards from the vertex.
Therefore, the equation y = -1/2(x-3)² + 5 reduces the graph, which means that the graph decreases as we move away from the vertex (3, 5) in both directions along the x-axis.

Answer:
11 over 9 [tex](\frac{11}{9})[/tex]
Step-by-step explanation:
What is a fraction?A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
To solve for [tex]\frac{2}{3} +\frac{5}{9}[/tex], we need to first convert these fractions so that they share a common denominator.
What is a common denominator?A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.
If a common denominator just refers to 2 fractions having the same denominator, we can simply multiply the numerator and denominator of the fraction [tex]\frac{2}{3}[/tex] by a number. To solve for that number, we can divide 9 by 3.
9 ÷ 3 = 3Now that we know that the number is 3, multiply both by 3.
2 × 3 = 63 × 3 = 9Now the fraction looks like this: [tex]\frac{6}{9}[/tex].
We can now change the expression to this:
[tex]\frac{6}{9}+ \frac{5}{9}[/tex]When adding fractions with the same denominator, we can just add the 2 numerators and keep the common denominator the same.
6 + 5 = 11Now just insert 11 in as the numerator:
[tex]\frac{11}{9} = 1\frac{2}{9}[/tex]Therefore 2 over 5 plus 5 over 9 is 11 over 9.
Veronica walks dogs in her neighborhood for extra money during the summer. For each dog walk, she earns $5.25. On Monday, she completes 3 walks, and on Tuesday she completes 2 walks. She estimates that in order to save up for a new purse that costs $86, she needs to complete 12 more walks by the end of the week.
Answer:
Veronica is correct
Step-by-step explanation:
On Monday, Veronica earns 3 walks * $5.25 per walk = $15.75.
On Tuesday, Veronica earns 2 walks * $5.25 per walk = $10.50.
So far, Veronica has earned a total of $15.75 + $10.50 = $26.25.
To reach her goal of $86, Veronica needs to earn an additional $86 - $26.25 = $59.75.
Since Veronica earns $5.25 per walk, she needs to complete $59.75 ÷ $5.25 per walk = 11.38 walks.
Since Veronica cannot complete a fraction of a walk, she will need to complete 12 more walks (rounded up from 11.38) by the end of the week.

The area of the sector formed by angle DFE is approximately 3.29 square feet.
What is area of the sector?
To find the area of a sector of a circle, we need to know the central angle that defines the sector and the radius of the circle. We can then use the formula:
Area of sector = (central angle / 360 degrees) x π x (radius)²
In this case, we are given that the radius of the circle is 4 feet and the central angle that defines the sector is 75 degrees. Therefore, the area of the sector can be calculated as:
Area of sector = (75 / 360) x π x (4)²

people at time t=0 In each of the following cases, write a formula for the population P, of the town as a function of year t
(a) The population increases by 60
people per year.
P= X people x=?
Answer:
The formula for the population P, of the town as a function of year t, if the population increases by 60 people per year, is:
P(t) = 1900 + 60t
where t is the number of years elapsed since t=0.
The formula for the population P, of the town as a function of year t is
P = 1900 + 60t
We have,
If the population increases by 60 people per year, then we can use the following formula to find the population P as a function of time t (in years):
P = 1900 + 60t
Here, the initial population at t=0 is 1900 people, and the population increases by 60 people per year,
So we add 60t to the initial population to get the population at time t.
For example,
If we want to find the population after 5 years, we can substitute t=5 into the formula:
P = 1900 + 60(5) = 2200
So the population after 5 years would be 2200 people.
Thus,
The formula for the population P, of the town as a function of year t is

Eric is observing the velocity of a runner at different times. After one hour, the velocity of the runner is 5 km/h. After three hours, the velocity of the runner is 3 km/h.
Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the runner at different times. Show your work and define the variables used. (5 points)
Part B: How can you graph the equation obtained in Part A for the first 5 hours? (5 points)
(10 points)
Answer:
Step-by-step explanation:
Part A:
Let's assume that the velocity of the runner changes linearly over time. We can use the slope-intercept form of a linear equation, y = mx + b, to describe the velocity of the runner at different times. In this case, the y-axis represents the velocity in km/h and the x-axis represents time in hours. We can define:
y = velocity of the runner in km/h
x = time in hours
The velocity of the runner changes by -2/3 km/h for every hour that passes. This gives us a slope of -2/3. We can use the point-slope form of a linear equation to find the equation of the line:
y - 5 = -2/3(x - 1)
Simplifying this equation, we get:
3y - 15 = -2x + 2
Rearranging to standard form, we get:
2x + 3y = 17
So the equation in two variables in standard form that can be used to describe the velocity of the runner at different times is 2x + 3y = 17.
Part B:
To graph the equation obtained in Part A for the first 5 hours, we can simply plot points for different values of x and y. For example, we can use x = 0, 1, 2, 3, 4, and 5 to find the corresponding values of y using the equation 2x + 3y = 17. Then we can plot these points on a graph and connect them with a straight line.
Here are the values of y for different values of x:
x = 0, y = 17/3
x = 1, y = 5
x = 2, y = 13/3
x = 3, y = 3
x = 4, y = 7/3
x = 5, y = 1
Plotting these points and connecting them with a straight line, we get the graph of the equation 2x + 3y = 17 for the first 5 hours:

Part A:
Let v be the velocity of the runner in km/h and let t be the time elapsed in hours. We can use the two given data points to form a system of two equations:
v = 5 when t = 1
v = 3 when t = 3
To find the equation in standard form, we can first use point-slope form:
v - 5 = m(t - 1) (using the point (1, 5))
v - 3 = m(t - 3) (using the point (3, 3))
Simplifying both equations:
v - 5 = m(t - 1)
v - 3 = m(t - 3)
v = mt + (5 - m)
v = mt + (3m - 3)
Setting the right-hand sides equal to each other:
mt + (5 - m) = mt + (3m - 3)
Simplifying and rearranging:
-m = -2
m = 2
Substituting m = 2 into one of the equations above:
v = 2t + 3
This is the equation in two variables in standard form that describes the velocity of the runner at different times.
Part B:
To graph the equation v = 2t + 3 for the first 5 hours, we can plot points for different values of t and then connect them with a line. For example:
When t = 0, v = 3, so the point (0, 3) is on the line.
When t = 1, v = 5, so the point (1, 5) is on the line.
When t = 2, v = 7, so the point (2, 7) is on the line.
When t = 3, v = 9, so the point (3, 9) is on the line.
When t = 4, v = 11, so the point (4, 11) is on the line.
When t = 5, v = 13, so the point (5, 13) is on the line.
Plotting these points on a coordinate plane and connecting them with a line, we get the graph of the equation v = 2t + 3 for the first 5 hours:

Step-by-step explanation:
Rewrite the following equations in the form (x−p)2=q 0=x^2-18x+1 and the equation x^2+26x+167.5=0
For the first equation, we can complete the square to find its vertex form. Here's how we do it:
0 = x^2 - 18x + 1
0 = (x - 9)^2 - 80
So we have (x - 9)^2 = 80. This is in the form (x - p)^2 = q, where p = 9 and q = 80.
For the second equation, we can complete the square in a similar way:
x^2 + 26x + 167.5 = 0
x^2 + 26x = -167.5
x^2 + 26x + (26/2)^2 = -167.5 + (26/2)^2
(x + 13)^2 = 9.25
So we have (x + 13)^2 = 9.25. This is in the form (x - p)^2 = q, where p = -13 and q = 9.25.
I hope that helps!
Please anyone help me with number 2 ? Thank you:))
Answer:
subtract 20; 80, 60, 40
The pattern is to subtract 20 from the previous term.
Next three terms: 20, 0, -20.
Therefore, the sequence continues as follows:
80, 60, 40, 20, 0, -20.
A, B, and C started a business with Rs 60,000. Amount invested by 'A' and 'C' together is twice that of 'B', while the amount invested by 'A' and 'B' together is thrice that of 'C'. 'A' invested for 6 months, 'B' for 9 months, and 'C' for a year. Find the share of 'B' (in Rs) out of the total profit of Rs 3400.
Answer:
Step-by-step explanation:
Let the amount invested by A, B, and C be denoted by a, b, and c respectively.
From the given information,
a + b + c = 60000 ---(1)
a + c = 2b ---(2)
a + b = 3c ---(3)
Multiplying equation (2) by 3 and equation (3) by 2, we get:
3a + 3c = 6b
2a + 2b = 6c
Adding these two equations, we get:
5a + 5b + 5c = 0
a + b + c = 0
This is not possible as the sum of the investments cannot be zero. Therefore, there must be an error in the problem statement.
Without further information or correction, it is not possible to find the share of B in the profit.
