Using the distance formula, the distance between B and C is calculated as: 2.3 units.

The distance formula to apply is: d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Given the following:

B (3,−4) = (x1, y1)

C (5,−5) = (x2, y2)

Plug in the values into the distance formula

BC = √[(5−3)² + (−5−(−4))²]

BC = √[(2)² + (−1)²]

BC = √(4 + 1)

BC = √5

BC = 2.236068 ≈ 2.3 units.

Therefore, using the distance formula, the distance between B and C is calculated as: 2.3 units.

The absorbance of the given sample is 0.2076.

Length of the cuvette = 1 cm

Wavelength of the spectrophotometer = 620nm

Transmittance of the sample = 62%

We know, absorbance is related to transmittance by the formula written below;

A = log(1/T)                                                 equation 1

Also, percent transmittance %T = 100T

or we can write, T = (%T) / 100

On substituting value of T in equation 1 , we get

A = log(100/(%T))    

⇒ A = log(100) - log (%T)      

⇒ A = log([tex]10^{2}[/tex]) - log(%T)

⇒ A=  2log(10) - log(%T)    

We know, log10 = 1. On substituting the value of log 10 in above equation, we get

A = 2 - log(%T)

⇒ A = 2 - log(62)

⇒ A = 2 - 1.7924

⇒ A = 0.2076

The absorbance of the given sample is 0.2076.

Solving system of equations in two variable gives that the number of cards in every booster pack are 10  and number of cards in every premade deck are 32

What is system of equations in two variables and how to find its solution by substitution?

Let x and y be two variables and

a₁x+b₁y =c₁              

a₂x+b₂y =c₂        

Where a₁, a₂, b₁, b₂, c₁, c₂ are  constants   then  we can solve these simultaneous equations by substitution take value of x from equation (1) and then put it in (2) to get an equation for y only and then solve for y. put value of y in equation (1) to get value of x.

Let the number of cards in every booster pack are  x and the number of cards in every premade deck  be y

Number of cards in 5 booster packs will be 5x  and Number of cards in 4  premade deck will be 4y

As Oliver purchases 5 booster packs and 4 premade decks, which included a total of 178 cards.

Thus we get       5x + 4y = 178    .....(1)

Number of cards in 4 booster packs will be 4x  and Number of cards in 7  premade deck will be 7y

As Oliver received 4 booster packs and 7 premade decks, which included a total of 178 cards.

Thus we get     4x +7y = 264       ...(2)

System of equations to be solved is

5x + 4y = 178    .....(1)

4x +7y = 264       ...(2)

From (1) , we get x = [tex]\frac{178-4y}{5}[/tex]

Put this value in (2)

[tex]4(\frac{178-4y}{5}) +7y= 264\\\frac{712}{5} -\frac{16y}{5} +7y = 264\\\frac{712}{5}-264=\frac{16y}{5} -7y\\ y= 32\\x= \frac{178-4(32)}{5 }\\ x=50/5\\x=10[/tex]

Therefore x=10 and y= 32

The number of cards in every booster pack are 10   and number of cards in every premade deck are 32

a) Her gross pay will be $156

b) The domain is D: [10, 15]

c) The range is R: [$130, $195]

We know that Taylor earns 13 dollars per hour on her job at the grocery store.

Then, if she works x hours in the week, her gross wage will be given by the linear equation:

g(x) = $13*x

So,  if she works 12 hours, her gross pay will be:

g(12) = $13*12 = $156

we know that she works between 10 and 15 hours peer week, so the domain (set of the possible inputs of the function) is:

10 ≤ x ≤ 15 or [10, 15] in interval notation.

The range is the set of the outputs, the minimum of the rane is:

g(10) = $13*10 = $130

The maximum of the range is:

g(15) = $13*15 = $195

The slope of this isoquant equals -2.

A contour line formed across a set of locations where the same quantity of output is produced while changing the quantities of two or more inputs is called an isoquant (derived from quantity and the Greek word iso, meaning equal). A factor of production, like as labor, money, land, or organization, is typically represented by the x and y axes on an isoquant. Another name for an isoquant is a "Iso-Product Curve" or a "Equal Product Curve."

The isoquant mapping deals with the cost-minimization, profit, and output maximization problems of producers, whereas an indifference curve mapping helps consumers address the utility-maximizing problem. Indifference curves and isoquants diverge much more.

It would take 10 months to equate the population of both the towns

Let the number of months required to equate the population of both the town( Town A and Town B) be x

This question can be solved using linear equations

So, town A's population would be current population adjusted with migration of people  which is 42975-125x+150x

And town B's population would be current population adjusted with migration of people  which is 45225 -200x

As at the end of x months the population of the two towns is equal, so equating both the linear equations

 42975 -125x +150x = 45225-200x

Now solving the equation for x

150x-125x+200x= 45225-42975

225x=2250

Therefore x= 2250/225= 10

Given, the expression is kn/3k⁻³n⁻⁵

now we must simplify the expression with the help of the negative exponent rule.

A base that is on the fraction line's denominator side can be indicated by a negative exponent. In other words, according to the negative exponent rule, a number with a negative exponent should be added to the numerator and vice versa.

The length of rectangular field is 36.76 m.

Distance is quantified by length. A quantity with the dimension of distance is called length in the International System of Quantities. Most measurement systems choose a length base unit from which all other units are derived. The fundamental unit for length in the International System of Units is the metre.

The term "length" refers to the measurement or size of something from end to end. In other terms, it is the greater of the upper two or third dimension of a geometric shape or object.

Area of rectangle is L × W = 800

given L = 15 + W

W × ( 15+ W) = 800

15W + [tex]W^{2}[/tex] = 800

[tex]W^{2}[/tex] + 15W - 800 = 0
