The proportional relationship between the total number of minutes, m, that mariam practices the piano after some number of days, d, can be represented by the equation m = 34dm=34d. At what rate did she practice, in minutes per day?.

Answers

Answer 1

The Rate at which she practices piano per day will be 34 minutes.

We know that Proportional relationships are relationships between two variables like x and y when their ratios got equivalent.

For example,  [tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex]. This is the proportional relationship between the variables, a, b, c, and d. In this a is equal to c (a = c) and b is equal to d(b = d).

In our question, the proportional relationship between total minutes (m) and the number of days (d) is given by:
m = 34d.

We need to find the rate, which can be defined as the total minutes spent on practice piano per day.

Minutes spent = m
Days = d

Rate = [tex]\frac{m}{d}[/tex]

So, we know, m  = 34d

[tex]\frac{m}{d}[/tex] = [tex]\frac{34}{1}[/tex] = 34

Hence, The rate is 34 minutes per day.

A polynomial is the quotient (with or without a remainder). multiplying this polynomial by the polynomial's divisor We get a polynomial with updated exponents and coefficients, so it's closed under multiplication.

A polynomial is defined as an equation composed of variables, constants, and exponents that are joined together using mathematical operations such as addition, subtraction, multiplication, and division.

If no remainder exists, the dividend is equal to the quotient multiplied by the divisor.

The quotient and divisor, as well as their product, the dividend, are both polynomials.

If there is a residual, it is added to the product of the quotient and divisor.

The polynomial dividend is the sum of the remainder and the product of the quotient and divisor.

As you finish listening to your favorite compact disc (CD), the CD in the player slows down to a stop. Assume that the CD spins down with a constant angular acceleration. If the CD rotates clockwise at 500 rpm (revolutions per minute) while the last song is playing, and then spins down to zero angular speed in 2.60 s with constant angular acceleration, what is ααalpha, the magnitude of the angular acceleration of the CD, as it spins to a stop? How many revolutions does the CD make as it spins to a stop?
20.1 rad/s^2
10.8 revolutions

Answers

CD makes approximate 10.9 resolutions to make as it spins to a stop.

Here we have to determine the number of rotations N ,the CD spun before it comes to a stop. We first need to express the initial angular velocity ω , in terms of rad/s by applying the conversion factor ω = 2πf × 1/60 min/s where f = 500 rpm.

Then we apply the equation for the angular displacement of the CD upon coming to a stop,

Ф=  (ωi²-ωf²)/2α , We have the final angular velocity of ωf = 0 rad/s and an angular acceleration of α = 20.1 rad/s² Now we proceed with finding Φ.

Ф=  (ωi²-ωf²)/2α

  = {(2Πf×1/60min/s)² - ωf²}/2α

  = {(2π(500 rpm) × 1/60 min/s) -0 rad/s}/2(20.1 rad/s²)

  ≈ 68.19792... rad

Now we divide the answer by 2π to find the answer ,N, or

N =   Ф/2π

N =   (68.19792... rad)/2ππ

N  ≈ 10.9 revolutions

So, CD makes approximate 10.9 revolutions to make it stop.

What is Privilege Creep?

The IT team will frequently need to re-grant credentials so that users may accomplish certain tasks when businesses choose to revoke all administrative capabilities from business users. For instance, many commercial off-the-shelf (COTS) apps and legacy programmes used in enterprise IT systems need privileges to function. The IT staff needs to restore local administrator access to business users so they can utilise these approved and necessary programmes.

As privileges are rarely removed once they have been granted again, organisations may find that many of their users eventually have local administrator rights once more.A user is only provided the minimal levels of access - or permissions - required to carry out his or her job functions under the principle of least privilege (PoLP), which is a notion in information security. It is widely regarded as a best practise in cybersecurity and is a crucial step in safeguarding privileged access to highly valuable data and assets. Beyond human access, least privilege applies.

Least privilege :

Applications, systems, and linked devices that require rights or permissions to carry out a necessary operation can all use the paradigm. Least privilege enforcement makes sure the machine tool only has the minimal access required. A mechanism to centrally store and secure privileged credentials is necessary for least privilege enforcement, combined with adaptable policies that can balance cybersecurity and compliance needs with operational and end-user needs.

On a given day, it is equally likely for the museum to have less than 300 visitors as it is to have more than 300 visitors.

Answers

The mean number of visitors to the museum is much greater than the median number of visitors.

What is median?

The value of the middle observation found after the data are arranged in ascending order is referred to as the median of the data. In many cases, it is challenging to take all of the facts into account when representing something, and in these cases, median is helpful. The median is one of the simples to compute statistical summary metrics. The median is also known as the place average since it uses the data that is in the center of a sequence to determine its value.

Option (a) is unquestionably incorrect since the probability that there will be 450 to 500 investors is extremely low (0.05), and investors are not, in fact, the visitors with the highest possibility of visiting the museum.

We will take the midpoint value of the class intervals as the given distribution is expressed as class intervals in order to simplify the data in this distribution.

Mean = 306

Since the mean(306) is coming out to be greater than the median (300)

Therefore the correct option is,

(C) the mean number of visitors to the museum is much greater than the median number of visitors.

Hence the mean number of visitors to the museum is much greater than the median number of visitors.

Answers

For the maximum area, the wire should be bent in the form of a circle and for the minimum area, the wire should bend into an equilateral triangle.

What is the area of any geometrical shape?

The area of a shape is the “space enclosed within the perimeter or within the boundary” of the given shape. We calculate the area for different shapes using math formulas.

Given that a piece of wire 10m long is cut into two pieces so now we have two wires with lengths of 5m and 5m.

One wire is bent into an equilateral so the perimeter of that triangle would be 3 m.

Perimeter = 3 m

3*side = 3 m

side = 1 m

Now the area of the equilateral triangle = [tex]A=\frac{\sqrt{3}}{4} $ $ \times $ (side)^2$[/tex]

                                                                   A = 0.4330 m² -----(I)

Now the circumference of the circle = 5 m

                     2π×r = 5

                      r = 5/2π

                      r = 0.7957 m.

Now the area of the circle = π×r²

                                           = 3.14 × (0.7957)²

                                           = 1.988 m² --------(II)

From (I) and (II), we can say that

Area of the equilateral triangle < Area of the circle

Hence, for the maximum area, the wire should be bent in the form of a circle and for the minimum area, the wire should bend into an equilateral triangle.

When we add a constant (which is not zero) to the term before it, the sequence's subsequent term is created. The following symbols stand in for it: a, ar, ar2, ar3, ar4, etc.

Geometric Progression (GP), a form of sequence in mathematics, is a series in which each subsequent term is created by multiplying each preceding term by a set integer, known as a common ratio. A geometric sequence of integers that follows a pattern is another name for this development.

We have,

f(n) = f(n - 1) + 4

And,

f(n) = 3(5)ⁿ⁻¹

f(1) = 3

Putting n=1

f(n) = f(n - 1) + 4

Now,

f(1) = f(1 - 1) + 4

3 = f(0) + 4

⇒ f(0) = 3 - 4 = -1

Here f(0)= -1

and  f(n) = 3(5)ⁿ⁻¹

Now,

f(1) = 3 × (5)¹⁻¹ = 3 × (5)⁰ = 3 × 1 = 3

f(1) = 3

Hence, the first term in both sequences is -1.

Find the absolute maximum and minimum of the function f(x,y)=x2+y2 subject to the constraint x4+y4=1296. As usual, ignore unneeded answer blanks, and list points in lexicographic order. Absolute minimum value: attained at ( , ), ( , ), ( , ), ( , ). Absolute maximum value: attained at ( , ), ( , ), ( , ), ( , ).

Answers

Minimum value and maximum value attained at 36 and [tex]2\sqrt{648}[/tex] respectively.

What is maxima and minima ?

Maxima and minima of a function are the largest and smallest value of the function respectively either within a given range or on the entire domain. Collectively they are also known as extrema of the function. The maxima and minima are the respective plurals of maximum and minimum of a function.

Given that f = [tex]x^{2}[/tex]+ [tex]y^{2}[/tex]

Let g = [tex]x^{4}[/tex] + [tex]y^{4}[/tex] = 1296

By Lagrange Multipliers:  grad(f) = λ grad(g)

or  <2x, 2y> = λ <4[tex]x^{3}[/tex], 4[tex]y^{3}[/tex]>

Equating like entries:

2x = 4λ[tex]x^{3}[/tex]=> x(2λ[tex]x^{2}[/tex] - 1) = 0

2y = 4λ[tex]y^{3}[/tex] => y(2λ[tex]y^{2}[/tex] - 1) = 0

Now there possible 3 cases :

(i) If x = 0, then   [tex]x^{4}[/tex] + 0 = 1296 => x = ±6.

(ii) If y = 0, then 0 + [tex]y^{4}[/tex]= 1296 => y = ±6

(iii) Otherwise, we have 2λ[tex]x^{2}[/tex] - 1 = 0 = 2λ[tex]y^{2}[/tex] - 1  => λ([tex]x^{2}[/tex] - [tex]y^{2}[/tex]) = 0.

If λ = 0, then both x = 0 and y = 0 and this is not possible since [tex]x^{4}[/tex]+ [tex]y^{4}[/tex]= 1296.

Otherwise,[tex]x^{2}[/tex] = [tex]y^{2}[/tex] ⇒ [tex]x^{4}[/tex] +  [tex]x^{4}[/tex] = 1296 => x = ± [tex]648^{1/4}[/tex]

(with x and y will have different signs)

Now we have following critical points (in lexicographic order):

(- [tex]648^{1/4}[/tex], - [tex]648^{1/4}[/tex])

(- [tex]648^{1/4}[/tex],  648^(1/4))

(-6, 0)

(0, -6)

(0, 6)

(6, 0)

( [tex]648^{1/4}[/tex], - [tex]648^{1/4}[/tex])

( [tex]648^{1/4}[/tex],  [tex]648^{1/4}[/tex])

Minimum value attained at f(±6, 0) = f(0, ±6) = 36

Maximum value attained at f(± [tex]648^{1/4}[/tex],  [tex]648^{1/4}[/tex]) = f(± [tex]648^{1/4}[/tex], - [tex]648^{1/4}[/tex]) = [tex]2\sqrt{648}[/tex]

a culture of bacteria has an initial population of 8600 bacteria and doubles every 5 hours. using the formula p t

Answers

The exponential growth formula for bacteria growth is P(t) = 8600 [tex](2)^(t/5)[/tex].

What is exponential growth?

     Exponential growth is a pattern of data that exhibits a greater increase over time, resulting in an exponential curve. Exponential is also a mathematical term meaning "with exponents". For example, if you raise a number to the 10th power, the number increases exponentially. Exponential growth is growth that increases at a constant rate.

Here given take Initial number of bacteria = 8600. rate of growth = 2.

It doubles every year. Then doubling time = 5 hours.

Now population growth after t years,

P(t) = Po [tex](2)^(t/5)[/tex]

=> P(t) = 8600 [tex](2)^(t/5)[/tex]

Therefore exponential growth formula is P(t) = 8600 [tex](2)^(t/5)[/tex].
