The Nth Term Of A Sequence

Answers

Answer 1

The first three terms of the given sequence are 1, -3, and -7 respectively.

What are sequence and series?

An arrangement of numbers in a specific order is referred to as a sequence. The total of a sequence's components, on the other hand, is known as a series.

Given, the [tex]n^{th}[/tex] term of a sequence is: [tex]u_{n}[/tex] = 5 - 4n

We need to find the first three terms, then n= 1, 2, 3 respectively

So, first term, n = 1, [tex]u_{1}[/tex] = 5 - 4*1 = 5 - 4 = 1

second term, n = 2, [tex]u_{2}[/tex] = 5 - 4*2 = 5 - 8 = -3

third term, n = 3, [tex]u_{3}[/tex] = 5 - 4*3 = 5 - 12 = -7

Hence, the first three terms of the sequence are 1, -3, and -7 respectively.

what is the answer of this question?

Answers

Answer:

8 years old

Step-by-step explanation:

Make Nick's age = x

Caroline's age = x + 12

Mark's age = x - 4

So,

x + (x + 12) + (x - 4)

Remove brackets:

x + x + 12 + x - 4 = 44

Collect like terms:

3x = 44 - 12 + 4

3x = 36

x = 12 

Mark is 8 yrs old

The expression 17n+11 represents the perimeter of the triangle. What is the length of the third side?

Answers

The expression 17n+11 represents the perimeter of a triangle, which is the sum of the lengths of the three sides of the triangle. Therefore, we can use this expression to determine the length of the third side of the triangle.

Since the perimeter of the triangle is equal to 17n+11, we know that the sum of the lengths of the three sides is equal to 17n+11. We can write this as:

a + b + c = 17n+11

where a, b, and c are the lengths of the three sides of the triangle.

To determine the length of the third side, we need to know the lengths of the other two sides. However, since the question does not provide this information, we cannot determine the length of the third side with certainty. In general, there are many different triangles that could have a perimeter of 17n+11, and the length of the third side could vary depending on the specific lengths of the other two sides.

Without additional information about the lengths of the other two sides, it is not possible to determine the length of the third side of the triangle.

A farmer wants to fence an area of 60,000 m2 in a rectangular field and then divide it in half with a fence parallel to one of the sides of the rectangle. What should the lengths of the sides of the rectangular field be (in m) in order to minimize the cost of the fence?.

Answers

The lengths of the sides of the rectangular field should be 244.95 m in order to minimize the cost of the fence.

Let the dimensions of a rectangular field be;

Length = l

Width = w

We know that the formula for perimeter of a rectangle is;

P = 2(l + w)

And the formula for area of the rectangle is;

A = lw

⇒ w = A/l

Subtitute w = A/l in the formula of perimeter of rectangle.

P = 2l + 2(A/l)

P = 2L + 2A/l

We differentiate above equation with respect to l,

dP/dl = 2 - 2A/l²

when dP/dl = 0 we get,

2 - 2A/l² = 0

l = √A

Substitute l = √A in the area equation,

A = w√A

w = A/√A

w = √A

This means, l = w = √A

Since length is equal to width, then it is a square.

We have been given that the area is 60,000 m²

So, l = w = √(60,000)

l = w = 244.95 m

Therefore, the lengths of the sides of the rectangular field should be 244.95 m

Answers

Answer:

y-10=   1/2(x-2) --- point slope form

Step-by-step explanation:

Point slope form is:

y- y1=m(x-x1)

y1= 10

m= y2-y1/x2-x1

y2= 6

x2= -10

x1= -2

Using point slope form and defining the variables using the given coordinates, the equation can be written.

Answer:

y-6 = -1/3(x-10)

Step-by-step explanation:

Let's use point slope form! The form of this is y-y1 = m(x-x1) where m is the slope.We have points to use, so let's find the slope.

The slope is rise over run, so we take the difference in y and divide it by the difference in x. This gives us [tex](10-6)/(-2-10)[/tex], which simplifies to -1/3. Now we plug in a point, say (-2, 10) for x1 and y1, and -1/3 for the slope, which gives us y-6 = -1/3(x-10)

ALTERNATE WAY:

Another way you could approach this is to plug in both the points to solve for m. Plug in both the y-values(10, 6) for y and y1 and both the x-values(-2, -10) for x and x1.

This gives us [tex]10-6 = m(-2-10)[/tex], which simplifies to [tex]4 = -12m[/tex]. Dividing both sides by -12 gives m = -1/3, which is the slope. Whichever way makes most sense works!

Answers

If an IR signal has a percent transmittance of 45%, then the sample absorbed 55% of the IR light

The percent transmittance of an IR signal = 45%

The equation of percent transmittance is

Percent transmittance = ( I / Io ) × 100

Where Io is the intensity of the IR signal entering the sample

I is the intensity of the IR signal leaving the sample

If the Io = I, then the percent transmittance is 100% that means the sample did not absorb any light and if Io= 0 then the the percent transmittance is 0% then sample absorbed all the light

Here, the percent transmittance is 45%, that mean the 55% of light absorbed by the sample
