(b) Estimate the instantaneous velocity of the particle when
t = 1.

Answers

Answer 1

The displacements are 2.84 cm, 2.77 cm, 2.83 cm and 2.83 cm respectively.

Instantaneous velocity of the particle at t =,1 is 0.72 cm/s.

How to calculate displacement and velocity?

a. To find the displacement of the particle at various times t, we can simply plug the given value of t into the equation s = 2 sin(t) + 3 cos(t) and evaluate:

[1, 2]: s = 2 sin(1) + 3 cos(1) = 2.84 cm

[1, 1.1]: s = 2 sin(1.1) + 3 cos(1.1) = 2.77 cm

[1, 1.01]: s = 2 sin(1.01) + 3 cos(1.01) = 2.83 cm

[1, 1.001]: s = 2 sin(1.001) + 3 cos(1.001) = 2.83 cm

b. To find the instantaneous velocity of the particle when t = 1, we need to find the derivative of the equation for displacement with respect to time, which will give us the velocity. The derivative is given by:

v(t) = ds/dt = 2 cos(t) - 3 sin(t)

Plugging in t = 1 into this equation, we find:

v(1) = 2 cos(1) - 3 sin(1) = 0.72 cm/s

So, the instantaneous velocity of the particle at t = 1 is approximately 0.72 cm/s.

f (x )equals fraction numerator 2 over denominator s plus 5 end fraction use the inverse laplace transform to find f (t ).

Answers

The inverse Laplace transform of (2/(s+5)) is f(t) = 2 * e^(-5t)u(t).

To find the inverse Laplace transform of F(s) = (2/(s+5)), we can use partial fraction expansion and then use a table of Laplace transforms to identify the inverse transforms.

Step 1: Perform partial fraction expansion on the fraction:

(2/(s+5)) = (2/5) * (1/(1+(s/5))) = (2/5) * (1/1 + (s/5))

Step 2: Recognize the form of the partial fraction as a geometric series, and use the formula for the sum of a geometric series to find the inverse Laplace transform:

The sum of this geometric series is

(2/5) * (1/(1-(-s/5)))

= (2/5) * (1/(1+s/5))

= (2/5) * (5/5+s)

= (2/(5+s))

Step 3: Use the table of Laplace transforms to find the inverse transform of (2/(5+s)):

f(t) = 2 * e^(-5t)u(t)

where u(t) is the unit step function.

To save for retirement, starting from her 30th birthday (t = 0), Miss Saver will invest

payment of $1000 will be made at the beginning of the first year. Every subsequent
payment increases by 5%.
She will retire at age 60, and will withdraw $X each year from her bank saving account
from then. The first withdrawal will be made at age 60. After 20 years (i.e. after the
20th withdrawal), she will have taken out all the money she had saved.
Assuming the effective annual interest rate is 2% perpetually, compute the value of X.
Give your answer to the nearest integer.

Answers

Answer:

To calculate the value of X, we first need to calculate the total amount of money Miss Saver will have saved by the time she retires at age 60.

We know that her first payment is $1000, and that every subsequent payment increases by 5%. Using this information, we can calculate the total payments made during the 30 years:

$1000 x (1 + 0.05)^30 = $1000 x 3.3201 = $3320.1

This is the total amount of money Miss Saver will have saved by the time she retires at age 60.

Next, we need to calculate the value of each annual withdrawal over the 20 years of withdrawals.

We know that the effective annual interest rate is 2% perpetually, so we can use the formula for the future value of an annuity:

FV = X * ((1 + r)^n - 1) / r

where X is the annual withdrawal, r is the interest rate (0.02), and n is the number of years (20).

We can use this formula to solve for X:

3320.1 = X * ((1 + 0.02)^20 - 1) / 0.02

X = 3320.1 * 0.02 / (1.02^20 - 1)

X = 3320.1 * 0.02 / 0.1135 = $292.36

Therefore, Miss Saver needs to withdraw $292.36 each year for 20 years to deplete her savings account.

Rounded to the nearest integer, the value of X is $292.

with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (0, 0) ← 2 points on the line

m = [tex]\frac{0-3}{0-(-2)}[/tex] = [tex]\frac{-3}{0+2}[/tex] = - [tex]\frac{3}{2}[/tex] , then

y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation

Based on the table, which college expenses would you consider fixed and which expenses would you consider variable?
Why?

Answers

Answer:Fixed expenses are those that do not change regardless of the level of production or consumption. Variable expenses are those that change in proportion to the level of production or consumption.

Based on the table provided, the following expenses can be considered fixed:

$4,640

$10,304

$2,500

$3,998

These expenses could be considered fixed because they do not appear to be directly related to the level of production or consumption. For example, $4,640 could be tuition fees, which remain the same regardless of how many classes a student takes or how much they use campus facilities.

The following expenses can be considered variable:

$3,000

$700

These expenses could be considered variable because they may be directly related to the level of production or consumption. For example, $3,000 could be the cost of books, which may change depending on the number of classes a student takes. $700 could be spending money for daily needs like food, transportation, or entertainment, which would likely vary depending on how much a student spends.

In conclusion, the distinction between fixed and variable expenses is based on the relationship between expenses and the level of production or consumption. The expenses listed above have been categorized as fixed or variable based on this relationship.

First plan charges rate of 24 cents per minute

C₁ = 24.t

C₁ is the charge of first plan

t is the number of minutes

Second plan charges $29.95 plus 9 cents per minute.

C₂ = 9t + $29.95

1 dollar = 100 cents

C₂ = 9t + 2995

Where C₂ is the charge of first plan

t is the number of minutes.

Let after x minutes the cost of both plans will be same

C₁ = C₂

Express the desired quantity as a definite integral and evaluate the integral using Theorem 2 .
Find the distance traveled by a train moving at 87 mph from 8:00 A.M. to 11:00 A.M.

Answers

Let t be the time elapsed in hours, starting at 8:00 A.M. So t = 0 at 8:00 A.M. and t = 3 at 11:00 A.M. The distance traveled by the train can be expressed as the definite integral of its velocity with respect to time:

distance = ∫(87 mph) dt from t = 0 to t = 3

Since mph is a unit of speed, we need to convert it to a unit of velocity (feet per second) in order to evaluate the integral:

87 mph = 87 miles/hour × 5280 feet/mile = 454840 feet/hour

distance = ∫(454840 ft/hr) dt from t = 0 to t = 3

distance = 454840 ft/hr * t from t = 0 to t = 3

distance = 454840 ft/hr * 3 hours

What is a ratio?

A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare the numbers, and you can compare them using division.

Currently, there is 1 red circle and 3 blue circles, making the ratio 1: 3.

Adding 1 red circle would make the ratio 2: 3.Adding 8 circles would make the ratio 9: 3.Adding 11 red circles would make the ratio 12: 3.

The ratio 12:3 can be simplified to get 4:1.

12 ÷ 3 = 43 ÷ 3 = 1

Therefore, you will need to add 11 red circles to get the ratio 4: 1.

the passenger section of a train has width 2x-7, length 2x+3, and height x-2, with all dimensions in meters. solve a polynomial equation to determine the dimensions of the section of the train if the volume is 117m3

Answers

The dimensions of width, length and height of the passenger section of the train are 3 meters, 13 meters and 3 meters respectively.

What are the dimensions of the passenger section of the train?

The volume of a rectangular prism is expressed as;

V = w × h × l

Where w is the width, h is height and l is length

Given that;

Width of the section = 2x - 7Length of the section = 2x + 3Height of the section = x - 2Volume = 117 m³

First, plug in the given values into the above formula and solve for x.

V = w × h × l

117 = ( 2x - 7 )( 2x + 3 )( x - 2 )

Expand using FOIL method

( 2x - 7 )( 2x + 3 )( x - 2 ) = 117

( 2x(2x) + 2x(3) - 7(2x) - 7(3) )( x - 2) = 117

( 4x² - 8x - 21 )( x - 2 ) = 117

Expand

4x³ - 16x² - 5x + 42 = 117

4x³ - 16x² - 5x + 42 - 117 = 0

4x³ - 16x² - 5x - 75 = 0

Using rational roots text

(x - 5)(4x² + 4x + 15 ) = 0

( x - 5 ) = 0

x - 5 = 0

x = 5

4x² + 4x + 15 = 0

x = -1±i√14 / 2

Since dimensions are real and positive numbers, we use;

x = 5

To determine the dimensions of the passenger section of the train, plug in x = 5 and simplify.

Width = 2x - 7 = 2( 5 ) - 7 = 10 - 7 = 3 meters

Length = 2x + 3 = 2( 5 ) + 3 = 10 + 3 = 13 meters

Height = x - 2 = 5 - 2 = 3 meters

which of the following decimal numbers can be represented accurately with a finite number of binary bits in the binary system?

Answers

Among the given, only 0.5 can be exactly represented in binary notation with a finite number of bits

Hence, option (d) is the correct choice.

Binary is a base-2 number system in which a number is represented by two states: 0 and 1. We can also refer to it as a true and false condition. A binary number is constructed in the same manner as a decimal number.

Binary data is information expressed or displayed using the binary number system. Binary data is the only type of data that a computer can directly understand and execute. It is represented numerically as a series of zeros and ones.

The binary representation of 0.5 is 0.1_2, and it is the only terminating fraction among the available possibilities.

As a result, it is the only fraction that can be expressed precisely.

All of the other possibilities have a non-terminating fraction portion and hence cannot be expressed accurately with a limited amount of bits.

How many terminating zeros are at the end of 6311! ,when this number is multiplied out?

Answers

The number of terminating zero when the number 6311! is  multiplied out is 252

What it terminating zeros?

In mathematics, trailing zeros are a series of digits (usually 0) that follow a number's decimal form or, more broadly, any positional representation.

In mathematics, the term "factorial" refers to the product of all positive integers that are less than or equal to a certain positive integer, which is followed by an exclamation point.

Thus, factorial five is denoted by the symbol 5!, which stands for 1 * 2 * 3 * 4 * 5. Factorial 0 is equivalent to 1 by definition.

Answer:

1576 terminating zeros

---------------------------

Terminated zeros at the end of number n! is found as the sum of the whole quotients of n and powers of 5 less than n.

Given:

n = 6311.

This is greater than 5⁵ = 3125 but less than 5⁶ = 15625.

Find each quotient of 6311 and 5¹ through 5⁵ :

6311/5¹ = 1262,6311/5² = 252,6311/5³ = 50,6311/5⁴ = 10,6311/5⁵ = 2.

Sum of the quotients is the number of terminating zeros:

1262 + 252 + 50 + 10 + 2 = 1576
