summation to integral? calculus
Answers
You should recognize the [tex]\dfrac3n=\dfrac{b-a}n[/tex] term on the right to represent the width of each equally-spaced subinterval of the integration interval [tex][a,b][/tex]. We don't know the endpoints' exact values just yet.
[tex]n[/tex] represents the total number of subintervals. If we fix it to some manageably small number, we can get a better picture of what the [tex]\left(\dfrac{3k}n-1\right)^4[/tex] term represents.
If [tex]n=3[/tex], the partial sum reduces to
[tex]\displaystyle\sum_{k=1}^3\left(\dfrac{3k}3-1\right)^4\dfrac33=\sum_{k=1}^3(k-1)^4=0^4+1^4+2^4[/tex]
This suggests the sum represents the left-endpoint Riemann summation to find the integral of [tex]x^4[/tex], and in particular, the integral seems to be taken over the interval [0, 3]. Taking the limit, we get
[tex]\displaystyle\lim_{n\to\infty}\sum_{k=1}^n\left(\dfrac{3k}n-1\right)^4\frac3n=\int_0^3x^4\,\mathrm dx[/tex]
Final answer:
In calculus, summation involves adding discrete values, while integration is akin to adding an infinite number of infinitesimally small products to find areas, volumes, etc. Integral calculus extends these concepts to continuous functions and is used, for example, to find position from acceleration by integrating twice.
Explanation:
The transition from summation to integral in calculus is an important concept that bridges the discrete world with the continuous. When we summate, we're adding together values to find a total amount. In a similar vein, an integral can be thought of as a continuous sum, where we're adding up infinitely small products to calculate an area, volume, or other quantities.
When performing an integral, the dimensions of what we're integrating must be consistent. For example, if we're integrating velocity (v) with respect to time (t), we obtain a dimension that is the product of the two, such as distance. This principle is rooted in the requirement of dimensional consistency, analogously understood in the phrase "You can't add apples and oranges."
Understanding the relationship between discrete sums and continuous integrals is crucial for applications in various fields, such as physics where integrals can represent cumulative effects over time or space. For example, integrating an acceleration function gives us velocity, and further integration yields position. This process allows us to work backward from acceleration to position, utilizing the power of integral calculus.

Let ABCD be a cyclic quadrilateral. Let P be the intersection of AD and BC, and let Q be the intersection of AB and CD. Prove that the angle bisectors of angle DPC and angle AQD are perpendicular.
Answers
Cyclic quadrilateral ABCD.
Produce AD and BC to meet at P.
Produce AB and CD to meet at Q,
Angle bisector PJ of angle DPC divides angle DPC into two equal parts,x.
Angle bisector QI of angle AQD divides angle AQD into two equal parts,y.
Solution:
Construct segment PQ.
Name U= angle BPQ
Name V=angle BQP.
See attached figure.
Steps:
1. Consider triangle BPQ:
U+V=angle ABP (exterior angle)........................(1)
2. Consider triangle DPQ
U+2X+V+2Y = 180-angle PDQ (exterior angle)
= angle ABC (cyclic quad->opposite angles are supplementary)
=>
U+2X+V+2Y = angle ABC...................................(2)
3. Add (1) and (2)
U+V + U+2X+V+2Y = angle DPQ+angle ABC
=>
2(U+V+X+Y)=180 degrees (angles ABP and ABC lie on a straight lie)
=>
U+V+X+Y = 90 degrees = angle IKJ
4. angle bisectors PJ and QI are perpendicular.

Also, the verified Tutor above is in fact correct, but this answer is way more simple and easier to understand, thank you for your time :D
Explanation:
First, we need to find out the questions, even though the first question is, "What is the equation?". So, to the find the answer to how many questions there are in total we need to grab the total points "[tex]76[/tex]" and divide that by "[tex]4[/tex]" because that'll tell us how many questions that he answered correct. Especially since the "[tex]10[/tex]" questions he got wrong didn't affect his points.
So [tex]\frac{76}{4} =19[/tex]. Now we must add 10 to 19. [tex]10+19=29[/tex]. And so [tex]29[/tex] is the total amount of questions. Now we must write down how we found out. We found out by dividing [tex]76[/tex] and [tex]4[/tex], then we added [tex]10[/tex]!
Conclusion:
As simple as that, we found out how many questions there were in total and how we found out! Thank you for sticking with me♥!
which has the smallest value 11 , 0.675,1.23,0.42,1.011
Answers
Here are the numbers listed in order from least to greatest.
0.42, 0.675, 1.011, 1.23, 11
The reason has to do with the values of the position of the numbers. All Numbers to the left of the decimal point are whole numbers. Any number with numbers to the left have a whole number which is bigger than any decimal.
To the right of the decimal point the place values gets smaller the further you are to the right.
Compare 0.42 and 0.675
The 4 and 6 are both in the tenths place, therefore 0.42 is the smallest no matter how many more digits either has to the right of that number.

Answers
Answer:
Option B) 3
Step-by-step explanation:
we have the number
4162 0012 3456 789a
Find the value of a (check number)
step 1
Multiply every even-position digit (when counted from the right) in the number by two. If the result is a two digit number, then add these digits together to make a single digit
4162 0012 3456 789a
9(2)+7(2)+5(2)+3(2)+1(2)+0(2)+6(2)+4(2)
(18)+(14)+(10)+(6)+(2)+(0)+(12)+(8)
Remember that If the result is a two digit number, then add these digits together to make a single digit
so
(1+8)+(1+4)+(1+0)+(6)+(2)+(0)+(1+2)+(8)
(9)+(5)+(1)+(6)+(2)+(0)+(3)+(8)=34
step 2
add every odd-position digit
4162 00123456 789a
so
8+6+4+2+0+2+1=23
step 3
Adds the result in step 1 and the result in step 2
34+23=57
The check-digit is what number needs to be added to this total to make the next multiple of 10
In our case, we’d need to add 3 to make 60
therefore
The check number is 3

A pet store has 26 rabbits and hamsters. The number of rabbits is 2 more than double the number of hamsters. How many hamsters does the pet store have?
Answers
[tex]3x26 \: maybe[/tex]
Let the number of rabbits in the pet store is x
And the number of hamsters in the pet store is y.
Now, we have been given that pet store has 26 rabbits and hamsters. Thus, we have the linear equation
[tex]x+y=26...........(1)[/tex]
Now, number of rabbits is 2 more than double the number of hamsters. Hence, we have
[tex]x=2+2y[/tex]
Substituting this value of x in equation 1, we get
[tex]2+2y+y=26\\ 3y=24\\ y=8[/tex]
Thus, there are 8 hamsters in the pet store.

y = 60x + 40
y = 50x + 80
Equaling both equations we have:
60x + 40 = 50x + 80
From here, we clear the value of x:
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 weeks
