use limit laws to find: (a) limit as (n to infinity) [n^2-1]/[n^2 1] (b) limit as (n to-infinity) [n-1]/[n^2 1] (c) limit as (x to 2) x^4-2 sin (x pi)

Answers

Answer 1

The limit as n approaches infinity of [(n^2 - 1)/(n^2 + 1)] is equal to 1. The limit as n approaches infinity of [(n - 1)/(n^2 + 1)] is equal to 0.

(a) The limit as n approaches infinity of [(n^2 - 1)/(n^2 + 1)] is equal to 1.

To see why, note that both the numerator and denominator approach infinity as n goes to infinity. Therefore, we can apply the limit law of rational functions, which states that the limit of a rational function is equal to the limit of its numerator divided by the limit of its denominator (provided the denominator does not approach zero). Applying this law yields:

lim(n→∞) [(n^2 - 1)/(n^2 + 1)] = lim(n→∞) [(n^2 - 1)] / lim(n→∞) [(n^2 + 1)] = ∞ / ∞ = 1.

(b) The limit as n approaches infinity of [(n - 1)/(n^2 + 1)] is equal to 0.

To see why, note that both the numerator and denominator approach infinity as n goes to infinity. However, the numerator grows more slowly than the denominator, since it is a linear function while the denominator is a quadratic function. Therefore, the fraction approaches zero as n approaches infinity. Formally:

lim(n→∞) [(n - 1)/(n^2 + 1)] = lim(n→∞) [n/(n^2 + 1) - 1/(n^2 + 1)] = 0 - 0 = 0.

(c) The limit as x approaches 2 of [x^4 - 2sin(xπ)] is equal to 16 - 2sin(2π).

To see why, note that both x^4 and 2sin(xπ) approach 16 and 0, respectively, as x approaches 2. Therefore, we can apply the limit law of algebraic functions, which states that the limit of a sum or product of functions is equal to the sum or product of their limits (provided each limit exists). Applying this law yields:

lim(x→2) [x^4 - 2sin(xπ)] = lim(x→2) x^4 - lim(x→2) 2sin(xπ) = 16 - 2sin(2π) = 16.

Write an explicit and recursive rule for the geometric sequence -5, 10, -20, 40… and use it to find the 12th

Answers

Answer:

See solutions below

Step-by-step explanation:

Given the sequence -5, 10, -20, 40...

The nth term of the GP is expressed as;

Tn = ar^n-1

a is the first term

r is the common ratio

n is the number of terms

From the sequence, a = -5

r = 10/-5 = -20/10 = -2

Substitute

Tn = -5(-2)^n-1

This gives the explicit formula

For recursive;

a1 = -5

a2 = 10 = -2(-5) = -2a1

a3 = -20 = -2(10) = -2a2

From the shown sequence, we can see that;

an = -2an-1

This gives the recursive formula

Get the 12th term;

Using the explicit formula

T12 = -5(-2)^12-1

T12 = -5(-2)^11

T12 = -5(-2048)

T12 = 10240

Hence the 12th term is 10240

19^2 = 19 * 19 = 361

20^2 = 20 * 20 = 400

369 is between 361 and 400, so the side of the table is between 19 in. and 20 in.

Answer:

19 in. and 20 in.

Step-by-step explanation:

Answer:

175 pages

Step-by-step explanation:

Answer:

. 175

Step-by-step explanation:

There are 2 ways that we can find the answer to this question:

1. Take 1/4 of 697

2. Take 3/4 of 697 and minus the product from 697.

Let's do it both ways:

If we are doing it the first way it would look like this:

(1/4)(697) = 175

Note that we get 1/4 because Huey already read 3/4 of the book so he has 1/4 left.

The second way would look like this:

(3/4)(697) = 523

679 - 523 = 174 (roughly 175)

Therefore, the answer to your question would be . 175. pls mark brainliest

How many LaTeX: \frac{1}{3}1 3 inch cubes does it take to fill a box with width LaTeX: 2\frac{2}{3}2 2 3 inches, length LaTeX: 3\frac{1}{3}3 1 3 inches, and height LaTeX: 2\frac{1}{3}2 1 3 inches?

Step 1

We find the volume of the box

= Length × Width × Height

Length = 3 1/3 inches = 10/3 inches

Width = 2 2/3 inches = 8/3 inches

Height = 2 1/3 inches = 7/3 inches

The volume of the box =

10/3 inches × 8/3 inches × 7/3 inches

= 560/9 cubic Inches

= 62 2/9 cubic inches

Step 2

How many 1/3 inch cubes would fill the box.

This is calculated as:= 62 2/9 cubic inches/ 1/3 inches

= 560/9 ÷ 1/3

= 560/9 × 3/1

= 186.66666667 cubes

Approximately = 186.7 cubes

A object falls at 16t^2 feet in t seconds you drop a rock from a bridge that is 906 what is the hight in feet after the rock is droped

Answers

Answer:

824 feet

Step-by-step explanation:

Given

[tex]h(t) = 16t^2[/tex]

[tex]H = 906[/tex] -- Initial Height

Required

Calculate the height after 2 seconds --- missing from the question

First, we calculate the distance moved in 2 seconds

[tex]h(t) = 16t^2[/tex]

[tex]h(2) = 16*2^2[/tex]

[tex]h(2) = 16*4[/tex]

[tex]h(2) = 64[/tex]

This means that the object covered 64feet

The object current height is then calculated as:

[tex]Height = H - h(t)[/tex]

t = 2. So, the equation becomes

[tex]Height = H - h(2)[/tex]

Substitute values for H and h(2)

[tex]Height = 906- 64[/tex]

[tex]Height = 824[/tex]
