Enter your answer in the boxes.
y =
x +
Answer:
y = [tex]-\frac{3}{5}[/tex] x + 3
Step-by-step explanation:
To find slope you need to take y2-y1 divided by x2-x1. First to the subtraction. Y2 is 3 in this problem and y1 is 0. X2 is 0 and x1 is 5. 3-0 = 3 and 0-5 = -5. Now we have the equation [tex]-\frac{3}{5}[/tex] as the slope.
Slope-intercept form is y= mx+b so plug in [tex]-\frac{3}{5}[/tex] to get y = [tex]-\frac{3}{5}[/tex] x + b
The y-intercept is the coordinate where the x is equal to zero. (0,3) is the coordinate that meets this requirement. The y coordinate is 3 so that is the y-intercept. Plug that in to y = [tex]-\frac{3}{5}[/tex] x + b to get = [tex]-\frac{3}{5}[/tex] x + 3.

A worker on a scaffolding 75 ft above the ground needs to lift a 500 lb bucket of cement from the ground to a point 30 ft above the ground by pulling on a rope weighing 0.5 lb/ft. Choose the integral needed to calculate how much work is required?
Answer:
W = 15900 ft.lb
Step-by-step explanation:
From the given information.
Consider y to be the distance from the ground towards the bucket of the cement.
At height y, suppose the bucket is lifted by Δy.
Then, the workdone can be = 500Δy + 0.5(75 - y) Δy
where;
The bucket of the cement = 500Δy
The remaining of the rope = 0.5(75 - y) Δy
However; the workdone (W) can be calculated as:
[tex]W = \int^{30}_{0} \ 500 \ dy + \int^{30}_{0} \ 0.5 (75-y ) \ dy[/tex]
[tex]W = 500 \times 30 + 0.5 \bigg(75 \times 30 - \dfrac{1}{2} \times 30^2 \bigg )[/tex]
W = 15000 + 0.5 ( 2250 - 450)
W = 15000 + 900
W = 15900 ft.lb
The required work is [tex]15,900 \ ft-lb[/tex].
Integral Calculus:Integral Calculus is the branch of calculus where we study integrals and their properties. Integration is an essential concept which is the inverse process of differentiation. Both the integral and differential calculus are related to each other by the fundamental theorem of calculus.
Let [tex]x[/tex] be the distance from the ground to the bucket of cement.
At the height [tex]x[/tex], if the bucket is lifted by [tex]\Delta x[/tex], the work done is,
[tex]500\Delta x+0.5\left ( 75-x \right )\Delta x[/tex].
(See the attached figure below).
The [tex]500\Delta x[/tex] term is due to the bucket of cement; the [tex]0.5\left ( 75-x \right )\Delta x[/tex] term is due to the remaining cable.
So, the total work, [tex]W[/tex], required to lift the bucket is,
[tex]W=\int_{0}^{30}500dx+\int_{0}^{30}0.5\left ( 75-x \right )dx \\ =500.30+0.5\left ( 75.30-\frac{1}{2}30^{2} \right ) \\ =15,900 \ ft-lb.[/tex]

find the difference 41 - 275
Answer:
-234
Step-by-step explanation:
Subtracting 275 from 41 would equal -234.
The difference between 41 and 275 is -234.
To find the difference between 41 and 275, we perform subtraction.
Subtraction is the process of finding the difference between two numbers. In this case, we are subtracting 275 from 41, which means we want to find how much smaller 275 is compared to 41.
Let's set up the subtraction:
41
- 275
Starting from the rightmost column, we subtract 5 from 1. Since 5 is greater than 1, we borrow 1 from the tens column, making the ones column 11 - 5 = 6. Then, we move to the tens column and subtract 7 from 4, which is not possible without borrowing from the hundreds column. So, we borrow 1 from the hundreds column, making it 3 - 1 = 2. Now, we can subtract 7 from 12 in the tens column, which gives us 5. Finally, we subtract the 2 in the hundreds column from 2, resulting in 0.
The final result is 234, indicating that 275 is 234 units larger than 41. In other words, the difference between 41 and 275 is 234.
Subtraction is an essential arithmetic operation used in various real-life situations, such as calculating changes in quantities, measuring distances, determining differences between values, and more. Understanding subtraction helps us comprehend the relationships between numbers and enables us to solve a wide range of mathematical and practical problems.

the area of square base of a water tank is 4m² and the height of the tank is 2.5m. find the capacity of the tank.in litre
Answer:
10000L
Step-by-step explanation:
Given parameters:
Area of square base = 4m²
Height of tank = 2.5m
Unknown:
Capacity of tank = ?
Solution:
The capacity of the tank is the volume of tank;
Volume of the tank = base area x height
Insert the parameters and solve;
Volume of the tank = 4 x 2.5 = 10m³
Now convert m³ to Litre;
1m³ = 1000L
10m³ will be 10 x 1000 = 10000L

1. 3 claims we can start off with are….we can support these claims by……
2. Our opponent believes….., however you should believe our side for the following reasons…..
3. The summary of the stance we are taking for our debate in 25 words is….
Answer:
No, students should not have to partake in extra after school activities. This is because, Students already have to work for about 7-8 hours, and then come home to maybe take care of sick parents, siblings, take care of pets, cook dinner, clean, study, do homework, and a lot more. It wouldn't be fair towards the student if they had add on stress. It's already tough to finish school and homework alone, and if you wanna throw on something else to their cheduloe they would never have time for themselves, or to get a good night of sleep to keep up their good grades.
