Step-by-step explanation:
if you mean x multiply 2 :
j(x) = 2x + 1
j(a+1) = 2(a+1) + 1
= 2a+ 2 +1
=2a + 3
if you mean x to the power of 2
j(x) = x^2 +1
j(a+1) = (a+1)^2 + 1
= a^2 + 2a + 1 +1
= a^2 + 2a + 2

The Piersons have paid $75 to enroll their son Fred at preschool. They will pay $152 a month in fees. Write and solve an equation to work out how many months it will take for the total bill to reach $683.
Answer: 4 months
Step-by-step explanation:
$75 + $152X = 683
That's the equation you need to set up, with X being the number of months.
To solve, first subtract 75 from both sides.
$152x = 608
Then, divide each side by 152
X = 4
The answer is 4 months.

What does the V-shape of the graph tell you about the dive? What information does it not tell you?
The coordinate (5, - 8) means the diver is 8 feets below sea level after 5 seconds
The average speed of the diver is 1.78 ft/s
(x, y)
X axis = time = 5 seconds
Y axis = Depth = - 8 feets (negative value = below sea level)
The coordinate (5, - 8) : This gives information about the time with respect to position(depth) of the diver. At the coordinate point (5, - 8) it shows that the diver is at a depth of - 8 after 6 seconds
Recall the formular for speed :
Average speed in water = Total distance in water/ total timetaken
Total distance on water = (0 to - 8) + (-8 to 0) = 16 feets
Total time taken = 9 seconds.
Average speed = 16 ft / 9 seconds = 1.78 ft/s

Problem 61

https://brainly.com/question/24517029
===========================================================
Problem 62
T(n) = nth triangular number
T(n) = n(n+1)/2 = 0.5n(n+1)
That squares to (0.5n(n+1))^2 = 0.25n^2(n+1)^2
The next triangular number after T(n) is
T(n+1) = 0.5(n+1)(n+1+1) = 0.5(n+1)(n+2)
That squares to 0.25(n+1)^2(n+2)^2
Notice how each squared result has 0.25 and (n+1)^2 found buried in them.
Let's say A = 0.25(n+1)^2
That would mean the first result 0.25n^2(n+1)^2 becomes An^2
The second result 0.25(n+1)^2(n+2)^2 becomes A(n+2)^2
Let's add those to see what happens
An^2+A(n+2)^2
An^2+A(n^2+4n+4)
A(n^2+n^2+4n+4)
A(2n^2+4n+4)
0.25(n+1)^2*(2(n^2+2n+2))
0.5(n+1)^2(n^2+2n+1+1)
0.5(n+1)^2((n+1)^2+1)
0.5k(k+1)
We see that the result is a triangular number where k = (n+1)^2
This shows that adding the squares of consecutive triangular numbers gets us another triangular number.
A few examples
3^2+6^2 = 9+36 = 45 which is in the form n(n+1)/2 when n = 96^2+10^2 = 36+100 = 136 which is in the form n(n+1)/2 when n = 16Answer: Triangular number===========================================================
Problem 63
I'll borrow some of the ideas from problem 62
We found that after squaring the nth and (n+1)th triangular numbers, we got An^2 and A(n+2)^2 respectively. We let A = 0.5(n+1)^2
Subtract those expressions to get...
A(n+2)^2 - An^2
A(n^2+4n+4)-An^2
A(n^2+4n+4-n^2)
A(4n+4)
4A(n+1)
4*0.5(n+1)^2*(n+1)
(n+1)^3
This proves that the difference between the squares of consecutive triangular numbers is a perfect cube, aka a cube number.
A few examples:
6^2 - 3^2 = 36 - 9 = 27 = 3^310^2 - 6^2 = 100-36 = 64 = 4^3Answer: Cube number===========================================================

The ratio of the number of adults to the number of students on a field trip has to be 2:11. Last year there was 504 more students on a field trip. If the school is expecting the same attendance this year, how many adults have to attend the field trip?
Answer:
112 adults
Step-by-step explanation:
2x+504=11x
11x-2x=504
9x=504
x=56
The ratio is 2:11 so we multiply 56 by 2 and 11. The 2 represents the Adults and the 11 represents the students.
56*2=112 adults
56*11 = 616 students
Just to double check if you do 616-112 it is exactly 504, Therefore the amount of adults is 112.

When 512 is divided by 313 using repeated subtraction, the quotient is 1. The answer in mixed form is [tex]1\frac{199}{313}[/tex].
What is repeated subtraction?Repeated Subtraction is a method that subtracts the equal number of items from a group, also known as division. Using this method, the same number is subtracted repeatedly from another larger number until the remainder is zero, or smaller than the number being subtracted.
Dividend = 512
Divisor = 313
Subtract 313 from 512 repeatedly.
512 - 313 = 199
Here, 313 is subtracted once from 512 with remainder as 199.
Hence, the quotient = 1, remainder = 199.
Answer in mixed fraction:
[tex]\frac{Dividend}{Divisor} =Quotient \frac{Remainder}{Divisor} = 1\frac{199}{313}[/tex]
