Answer:
-90
Step-by-step explanation:
(8-h)(jh+jh)
Since the values of h and j are given, we use substitution to replace the variables with their number values
(8-(-1))(j(-1)+j(-1) replaced all the h with -1
(8-(-1))((5)(-1) + (5)(-1)) replaced all the j with 5
Then we solve inside the parenthesis first
(8+1)(-5+(-5))
(9)(-10)
Then, multiply

TOPIC: Should students be required to participate in at least 1 after school extra-curricular activity?
I am writing for the __________ side. (affirmative or negative)
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.

The function f(c)=c/20 represents the number of ferry boat trips, f(c) needed to transport c cars in one day. If there are no more than 5,000 cars transported by the ferryboat daily, what is the maximum value for the function f?
Answer:
250
Step-by-step explanation:
Equation is f(c)= c/20
We know that there are NO MORE than 5,000 cars transported.
New equation would be
f(5000) =5000/20
5k divided by 20 is 250
less or equal to 250 in a euation would be
f(c) < or equal to 250

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]

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.

So 45 is a 150% increase from 18.
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.

Work out the value of angle x and how ??
Answer:
160 degrees
Step-by-step explanation:
Step 1: A straight line is 180 degrees. So 180 - 100, is 80 degrees. as the opposite angle measurement of the 100 degree.
Step 2: An isosceles triangle has two equal angle measurements, so two of its angles are 80 degrees.
Step 3: All angles in a triangle equal 180 degrees. So add them up (we will call the missing angle, Z) 180 = 80+80+Z. which equals 180= 160+z
Step 4: Solve it. You subtract 160 from both side which comes out to 20 = Z.
Step 5: Now you have the opposite angle of X. Going back to step 1, A straight angle is 180 degrees. 180 - 20 = 160. X = 160 degrees
