Any n-dimensional vector should be able to be represented in space.

The highest degree of terms is written first when writing a polynomial in its standard form, then the next highest degree, and so on.

If there are multiple variables in a single term, add the exponents of each term together and choose the largest sum or highest power of the variable to determine the polynomial's degree.

The Formula for chain rule is dy/dx = dy/du x du/dx

The chain rule is a formula used in differential calculus to get the derivative of a composite function. According to the chain rule, if y = f(g(x)), then the instantaneous rate of change of function f with respect to g and g with respect to x leads in an immediate rate of change of f in relation to x. As a result, y' = f'(g(x)) will be supplied as the derivative of y. g'(x). One of the crucial rules in differentiation is the chain rule.

The chain rule formula is as follows for the function y = f(x), where f(x) is a composite function such that x = g(t):

Formula for chain rule

This is how the chain rule of differentiation formula is typically expressed.

The volume of the gas at 6.4 × 10⁴ Pascals is 7.44×10⁻⁷m³.  The pressure of the gas is  5.47× 10⁶ Pascals

At a constant temperature, the volume of a gas is inversely proportional to its pressure. We can write:

V α 1/P

V = T/P   (where T is the constant of proportionality)

T = PV

SInce T₁ = T₂

Also, P₁V₁ = P₂V₂

We have pressure of 2.8 x 10⁶ Pascals and a volume of 1.7 x 10⁻⁸ m³

a) What will the volume of the gas be when its pressure is 6.4 × 10⁴ Pascals?

P₁V₁ = P₂V₂

2.8 × 10⁶ × 1.7×10⁻⁸ = 6.4 × 10⁴ × V₂

V₂ = (2.8 × 10⁶ × 1.7×10⁻⁸)/ (6.4 × 10⁴)

V₂ = 7.44×10⁻⁷m³

b) Work out the pressure of the gas when its volume is 8.7 x 10⁻⁹ m³

P₁V₁ = P₂V₂

2.8 × 10⁶ × 1.7×10⁻⁸  = 8.7 ×10⁻⁹ × P₂

P₂ = (2.8 × 10⁶ × 1.7×10⁻⁸)/ (8.7 ×10⁻⁹)

The volume of the tube is increasing at the rate of 0.6 cubic millimeters per second.

The formula V = r2h, where r is the radius and h is the height, describes the volume of a cylinder.

The tube's volume is V = (2 mm)2 (20 mm), which equals 125.66 mm3.

Dr/dt = -0.1 mm/s and dh/dt = 3 mm/s are the formulas used to calculate the rate of change of the radius and height, respectively.

Using the chain rule, the rate of change of the volume is given by

dV/dt = π·2·[(2 mm)·(-0.1 mm/s) + (20 mm)·(3 mm/s)] = 0.6 mm3/s.

Therefore, the volume of the tube is increasing at the rate of 0.6 cubic millimeters per second.

Part 1: The point of maxima is 21.212

Part 2: x = 21.212 is approximately equal to the year 2022

Part 3: The percentage at that time is 16.37%

Part 4: The rate of change of the percentage at that time is 0.294

Part 1:

p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236

where x is the number of years since 2000, data from 0<=x<=50

Differentiating the function with respect to x and equating it to 0

p'(x) = -0.00066x^2 + 0.028x - 0.0033

We will find the critical points of p'(x)

p''(x) = dp'(x)/dx  = -0.00132x + 0.028

Critical points of p'(x) lies at x where p''(x) = 0

Thus, -0.00132x + 0.028 = 0

x = 0.028/0.00132 = 21.212

Now, p'''(x) = -0.00132<0

x = 21.212 is a point of maxima of p'(x)

Therefore, the maximum possible values of x could lie at x = 21.212 as well as the extreme points of the domain p'(x), i.e. at x = 0 and 50

p'(0) = -0.00066(0)^2 + 0.028(0) - 0.0033 = -0.0033

p'(21.212) = -0.00066(21.212)^2 + 0.028(21.212) - 0.0033 = 0.2936

p'(50) = -0.00066(50)^2 + 0.028(50) - 0.0033 = -0.2533

Hence p'(x) attains maxima at x = 21.212

Therefore, p(x) increases most rapidly at x = 21.212

Part 2:

From the given condition in the question, x = 0 corresponds to the year 2000

Thus x = 21.212 is approximately equal to year 2022

Part 3:

The percentage at that time:

p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236

p(21.212) = -0.00022(21.212)^3 + 0.014(21.212)^2 - 0.0033(21.212) + 12.236

= 16.365

= 16.37%

Part 4:

Rate of change of the percentage at that time

p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236

p'(21.212) = -0.00066(21.212)^3 + 0.028(21.212) - 0.0033

The simplest form of  the exponent number of 3^(5/2) is √243.

What is exponential form of a number?

To express numbers that are either too large or too tiny, use exponential notation, which raises the number to the power of the appropriate exponent. The exponent's power might either take the positive or negative form.

For instance, we may express the exponential form of 5 × 5 × 5 × 5 as 5⁴, where 5 is the base and 4 is the power. The power here indicates how many times we are multiplying the base by itself.

Given number is 3^(5/2)

The base of the given number is 3 and exponent 5/2.

The Spearman correlation coefficient is a non-parametric measure of correlation that uses ranks rather than raw data to assess the strength of the relationship between two variables. This makes it more robust than the Pearson correlation coefficient, which relies on the assumption that the two variables have a normal distribution. Additionally, Spearman correlation coefficients are used to measure the degree of monotonicity between two variables, while Pearson correlation coefficients are not.

Layla should by not more than 4 outfits in order not to exceed her budget

The inequality expression is n  ≤ 4

price of a new bicycles = $418.55

2 bicycle reflectors = $19.39

a pair of bike gloves = $27.23

new biking outfits = $38.86 each

Nora's total money to spend at a bicycle store = $38.86

Layla's spending will never exceed the total spending at the bike shop, so it will be less than or equal to the total of other items

We write the expression as;

$640 ≤ $418.55 + 2 * $19.39 + $27.23 + n * $38.86

where n represents the number of the new biking outfits

$640 - ( $418.55+ 2 * $19.39 + $27.23 ) ≤. + n * $38.86

Events A and B dependent as the occurrence of one event affect the chances of the occurrence of the other event.

Probability is a branch of mathematics in which the chances of experiments occurring are calculated. It is by means of a probability, for example, that we can know from the chance of getting heads or tails in the launch of a coin to the chance of error in research.

To understand this branch, it is extremely important to know its most basic definitions, such as the formula for calculating probabilities in equiprobable sample spaces, probability of the union of two events, probability of the complementary event, etc.

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B).

Since we have given that

A be the event that Callista drives faster than the speed limit.

P(A)=0.34

B be the event that she gets to a wedding on time.

The probability that she gets to the wedding on time given that she drives faster than the speed limit is 0.85 i.e.

P(A|B)=0.85

but for A and B to be independent ,

P(A).P(B)= P(A and B)

A rectangle's greatest area is 32 square units.

Given:

A parabola's equation is y = 12 - x2, which is an even function

As a result, its rectangular shape is also even at the origin.

We are aware that the area of a rectangle is equal to its length times its width.

Here,

width = y, length = 2x

A = 2x, where (12 -  [tex]x^{2}[/tex])

⇒ A = 24x - 2[tex]x^{3}[/tex]

Consider the A derivative with regard to x.

⇒ A' = 24 - 6 [tex]x^{2}[/tex]

When A' = 0, the area is the largest.

⇒ 24 - 6x2 = 0

⇒ [tex]x^{2}[/tex] = 4

⇒ x = 2

Replace x with its value in y = 12 -  [tex]x^{2}[/tex].

Uniform models are only useful for equally likely probabilities, so they are ineffective here. In statistics, a uniform distribution is a type of probability distribution in which every possible outcome has an equal chance of occurring. Because each variable has an equal chance of being the outcome, the probability is constant.

All events have an equal chance of occurring in a uniform probability mode. Rolling any one side of a six-sided fair die, for example, has the same probability: one out of six.
