2. Ifj(x) = x2 + 1, find j(a + 1).

Answers

Answer 1

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.​

Answers

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?

Answers

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

Refer to this link where I solved the problem earlier

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?

Answers

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.

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.
