(a) 2, 5, 10, 17, 26, . . .
(b) 0, 2, 5, 9, 14, 20, . . .
(c) 8, 12, 17, 23, 30, . . .
(d) 1, 5, 23, 119, 719, . . .

Answers

Answer 1

The final closed formula answers for each part,

(a) an = n^2 + 1

(b) an = n(n + 1)(n + 2)/6

(c) an = 2n + 6

(d) an = n! + (n-1)! + ... + 2! + 1!

(a) The given sequence can be seen as the sequence of partial sums of the sequence of odd numbers: 1, 3, 5, 7, 9, . . . . That is, the nth term of the given sequence is the sum of the first n odd numbers, which is n^2. Therefore, the closed formula for the given sequence is an = n^2 + 1.

(b) The given sequence can be seen as the sequence of partial sums of the sequence of triangular numbers: 1, 3, 6, 10, 15, . . . . That is, the nth term of the given sequence is the sum of the first n triangular numbers, which is n(n + 1)(n + 2)/6. Therefore, the closed formula for the given sequence is an = n(n + 1)(n + 2)/6.

(c) The given sequence can be seen as the sequence of differences between consecutive squares: 1, 5, 9, 16, 21, . . . . That is, the nth term of the given sequence is the difference between the (n+1)th square and the nth square, which is (n + 1)^2 - n^2 = 2n + 1. Therefore, the closed formula for the given sequence is an = 2n + 6.

(d) The given sequence can be seen as the sequence of partial sums of the sequence defined recursively by a1 = 1 and an+1 = an(n + 1) for n ≥ 1. That is, the nth term of the given sequence is the sum of the first n terms of the recursive sequence. It can be shown that the nth term of the recursive sequence is n! (n factorial), and therefore the nth term of the given sequence is the sum of the first n factorials. That is, an = 1 + 1! + 2! + ... + (n-1)! + n!. Therefore, the closed formula for the given sequence is an = n! + (n-1)! + ... + 2! + 1!.

Justin purchased his dream car worth 18500 on a finance for 4 years. He was offered 6% interest rate.assuming no other chargers and no tax,we want to find his monthly installment.

Answers

Answer:

To calculate the monthly installment for Justin's car loan, we can use the formula for the present value of an annuity:

PV = (PMT / r) x [1 - 1 / (1 + r)^n]

where PV is the present value of the loan, PMT is the monthly payment, r is the interest rate per period (in this case, per month), and n is the number of periods (in this case, the number of months in 4 years, which is 48).

We know that PV is the amount of the car loan, which is N$18500. We also know that r is 6% per year, which is equivalent to 0.5% per month (since there are 12 months in a year). Finally, we know that n is 48.

Substituting these values into the formula, we get:

18500 = (PMT / 0.005) x [1 - 1 / (1 + 0.005)^48]

Simplifying this expression:

18500 = (PMT / 0.005) x 36.4358

PMT = 18500 / 36.4358 / 0.005

PMT ≈ N$402.87

Therefore, Justin's monthly installment for his car loan is approximately N$402.87.

When Nathan went to bed, the outside temperature was 28°F. When he woke up the next morning, the temperature had decreased to -13°F. By how many degrees did the temperature change during the overnight hours

Answers

The temperature changed by 41°F during the overnight hours, decreasing from 28°F to -13°F.

How is an expression determined?

The difference in temperature from 28°F to -13°F can be shown in one of two ways:

Temperature change equals final temperature - The starting temperatureTemperature change: (-13°F) - (28°F)Temperature change: -41°FTemperature change = final temperature minus initial temperature; temperature change = -13°F minus 28°F; temperature change = -41°F; temperature change = 41°F.

To calculate the change in temperature, the first exponent equation subtracts the initial temperature from the end temperature. The change in this instance is negative and points to a drop in temperature.

The absolute value function is employed in the second statement to guarantee a positive result regardless of whether the temperature rose or fell. The result is the same as the first expression in this instance, but with a positive sign.

A car travelling north at 48 km/hr is approaching an intersection. A truck travelling East at 60 km/hr is moving away from the same intersection. How is the distance between the car and the truck changing when the car is 9 m from the intersection and the truck is 40 m from the intersection?​

Answers

The rate at which the distance between the car and the truck is changing when the car is 9 m from the intersection and the truck is 40 m from the intersection is about 19.187 m/s

What is the rate of change of a function?

The rate of change of a function is an indication of how fast the function's output changes per unit change in the input of the function.

Let y represent the distance of the car from the intersection, and let x represent the distance of the truck from the intersection, we get;

The distance between the car and the truck, d, can be obtained from Pythagorean Theorem as follows;

d² = y² + x²

2·d·d/dt = 2·y·dy/dt + 2·x·dx/dt

dy/dt = The speed of the car = 48 km/h = 40/3 m/s

dx/dt = The speed of the truck = 60 km/h = 50/3 m/s

y = The distance of the car from the intersection = 9 m

x = The distance of the truck from the intersection = 40 m

d² = 9² + 40² = 1681

d = √(1681) = 41

d = 41 m

Therefore;

2×41×d/dt = 2×9 × 40/3 + 2 × 40 × 50/3 = 4720/3

d/dt = 4720/3/(2 × 41) = 2360/123 ≈ 19.187

d/dt ≈ 19.187 m/s

The rate of change distance between the car and the truck d/dt is about 19.187 m/s

create a formula with structured references to calculate the percentage of the Sticker Price in column E. Columns C and D have the sticker price and sale price, respectively.

Answers

The formula to calculate the percentage of the Sticker Price in column E using structured references would be:

=IFERROR((1-[Sale Price]/[Sticker Price])*100,"% Discount")

Define the term percentage?

A number or quantity can be expressed as a fraction of 100 using a percentage.It is often denoted by the symbol % (percent).

Assuming that the Sticker Price is located in column C and the Sale Price is located in column D, the formula to calculate the percentage of the Sticker Price in column E using structured references would be:

=IFERROR((1-[Sale Price]/[Sticker Price])*100,"% Discount")

In this formula, the percentage of the Sticker Price is calculated by subtracting the Sale Price from the Sticker Price, dividing the difference by the Sticker Price, and then multiply by 100 to convert the result into percentage. The IFERROR function is used to handle any errors that may occur if the Sale Price is missing or is equal to or greater than the Sticker Price. If an error occurs, the formula will display the text "% Discount".

Note that the structured references [Sale Price] and [Sticker Price] refer to the column headers rather than the cell references. This makes the formula more dynamic and easier to read, especially when working with large datasets.

The Solution(s) is/are ? .

Answers

The real solutions of the following equation are 5 and 1

[ Graph is attached below ]

Solving equation graphically:

To solve the given equation graphically we need to find the coordinate points that pass through the graph.

This can be done by taking 'x' values and solving for them 'y' values.  

Now draw the graph using the above coordinates and find the solution as shown below.

Here we have

x³ - 6x²+ 5x = 0  

Let y = x³ - 6x²+ 5x  

To draw the graph find the coordinates of points as follows

At x = 0 =>  y = (0) + (0) + (0) = 0

At x = 1 => y = (1)³ - 6(1)² + 5(1) = 0

At x = -1 => y = (-1)³ - 6(-1)² + 5(-1) = - 12

At x = 2 => y = (2)³ - 6(2) + 5(2) = 6

From the above calculation,

The coordinates of the points to draw the graph are (0, 0), (1, 0), (-1, -12), and (2, 6)

Here the solutions of the graph are the x-coordinate of points where the graph cuts the x-axis

From the figure, the graph will cut the x-axis at 1 and 5

Find the general anti-gradient, f, for the following: (i.e. f was the original function, and you are given the gradient of the function.) (a) Vf(x,y) = (6x + 4yº, –2 + 12xy?) (b) Vf(x,y) = ( 95 - 2e-20, - sako + 4y)

Answers

(a) The general anti-gradient for ∇f(x,y) = (6x + 4y^3, –2 + 12xy^2) is f(x,y) = 3x^2 + 4xy^3 – 2y + C

(b) The general anti-gradient for ∇f(x,y) = (6x/y^2 -2e^-2x, 6x^2/y^3+4y) is f(x,y) = 3x^2/y^2 + e^-2x + 2y^2 + C

(a) To find the general anti-gradient f for ∇f(x,y) = (6x + 4y^3, –2 + 12xy^2), we need to integrate each component of the gradient with respect to its corresponding variable.

Thus, we have

f(x,y) = ∫(6x + 4y^3) dx + C1

f(x,y) = 3x^2 + 4xy^3 + C1

f(x,y) = ∫(–2 + 12xy^2) dy + C2

f(x,y) = –2y + 4x y^3 + C2

where C1 and C2 are constants of integration

Therefore, the general anti-gradient for ∇f(x,y) = (6x + 4y^3, –2 + 12xy^2) is

f(x,y) = 3x^2 + 4xy^3 – 2y + C

where C is an arbitrary constant.

(b) To find the general anti-gradient f for ∇f(x,y) = (6x/y^2 -2e^-2x, 6x^2/y^3+4y), we need to integrate each component of the gradient with respect to its corresponding variable

Thus, we have

f(x,y) = ∫(6x/y^2 -2e^-2x) dx + C1

f(x,y) = 3x^2/y^2 + e^-2x + C1

f(x,y) = ∫(6x^2/y^3+4y) dy + C2

f(x,y) = 3x^2/y^2 + 2y^2 + C2

where C1 and C2 are constants of integration.

Therefore, the general anti-gradient for ∇f(x,y) = (6x/y^2 -2e^-2x, 6x^2/y^3+4y) is

f(x,y) = 3x^2/y^2 + e^-2x + 2y^2 + C

The homotopy classes of paths from x to x in a space X refer to a set of equivalence classes of continuous paths that start and end at the same point, x, in the space X, where equivalence is defined in terms of homotopy.

What is the homotopy about?

In other words, for any two paths, there exists a continuous transformation (called a homotopy) between them such that the endpoints remain fixed. Two paths are said to be homotopic if they can be continuously deformed into each other while keeping their endpoints fixed. The set of all paths that are homotopic to each other forms an equivalence class.

The homotopy classes of paths from x to x are important in algebraic topology, as they provide a way to study the topological structure of a space by analyzing the properties of the paths within it. They can also be used to define higher algebraic structures such as the fundamental group and higher homotopy groups.

What is a cone?

A cone is a three-dimensional geometric shape that has a circular base and a curved surface that tapers to a point, called the apex. The base of the cone is a circle, and the height of the cone is the perpendicular distance from the apex to the center of the base. The surface of the cone is made up of all the points that are equidistant from the apex and lie on the base.

According to the given information :

Consider an isosceles triangle with 82 inches of circumference and a leg length of 24 inches.

This means that 82 - 2(24) = 82 - 48 = 34 inches is the length of the other side.

The triangle is rotated along a line that passes through points B and D, with point D serving as the intersection of lines AC.

When this happens, a cone will be created in three dimensions with a base radius equal to the length of line AD (i.e. half of the length of line AC being the other side of the isosceles triangle).

The resulting cone's base radius is 1/2 (34) = 17 inches.

Todd Jefferson can buy 2 gallons of ice cream for $3.87, 3 gallons for $4.10, or 1 gallon for $1.98. What is the unit price of the best buy, rounded to the nearest tenth of a cent?

Answers

Answer: $1.367 per gallon (The 3 gallon ice cream is the best buy)

Explanation: For this problem we need to understand that a “unit price” is the cost for one of the item. In this case, our unit is one gallon of ice cream. So with that, we need to find the best deal. We can do that by dividing the total cost by the number of gallons.

$3.87 / 2 == $1.935 per gallon

$4.10 / 3 == $1.367 per gallon

$1.98 / 1 == $1.98 per gallon.

Look at these per gallon prices, we see the best buy for ice cream per gallon is the 3 gallon ice cream for $4.10 since the unit price is the cheapest.

do the compression values seem resonable given the 3 2 1 mix design, 0.50 w/c ratio and 7 days of curing

Answers

The mix design and w/c ratio used in the concrete mix are commonly used for M15 grade concrete, and achieving a compressive strength of 18 MPa after 7 days of curing may be reasonable depending on the target strength and other design specifications.

The actual compressive strength of 18 MPa achieved after 7 days of curing may be lower or higher than the target strength, depending on the design specifications and requirements.

However, the mix design of 3:2:1 (cement:sand:aggregate) with a water-cement (w/c) ratio of 0.50 is a commonly used mix proportion for M15 grade concrete. With proper curing and compaction, this mix design should be capable of achieving a compressive strength of at least 15 MPa at 28 days of curing.

The compressive strength is typically measured after 28 days of curing, not just 7 days. Therefore, it may be premature to conclude whether the achieved compressive strength of 18 MPa is reasonable without testing the concrete at 28 days of curing.

Here, FH = x + 27

Substituting the values we have:

18/x + 27 = x / 18

18(18) = x (x + 27)

x² + 27x - 324 = 0

Splitting the middle term we have:

(x + 36) (x - 9) = 0

x = -36 and x = 9

Since, length cannot be negative we have the value of x = 9.

Hence, for the triangles to be similar the value of FJ = 9.

divide 1350 into 5:4 and then do the same for 261​

Answers

Answer:

a) 750 and 600,

b) 145 and 116.

Step-by-step explanation:

A) For 1350 divided to two as 5 : 4, we need to add 5 and 4 first = 9:

Then, with the following, calculate the amount for 5:

[tex]\frac{1350}{9}[/tex] x 5

150 x 5

= 750 for 5, then for 4:

150 x 4

= 600 for 4.

B) For 261 divided with into 5 : 4, we need to add 5 and 4 = 9:

Then, with the following, calculate the amount for 5:

[tex]\frac{261}{9}[/tex] x 5

29 x 5

= 145 for 5. Finally, for 4:

29 x 4

= 116 for 4.
