The answer is k⁴n⁶/3 after solving the expression.

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.

that is, a⁻ⁿ = 1/aⁿ

therefore,  kn/3k⁻³n⁻⁵ = knk³n⁵/3

Multiply the monomials.

Monomials should be multiplied by adding the exponents to the coefficients before moving on to the variables. You can sum the exponents of monomials while multiplying them by the same base. The Product of Powers Property is used to describe this.

k⁴n⁶/3

Hence we get the answer after simplification as k⁴n⁶/3

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

Hence it would take 10 months to equate the population of both the towns

The solutions to the inequalities are h ≥ -14, v ≥ -19 and m ≤ 10

To do this, we simply solve the expressions one after the other

So, we have:

Divide both sides by -3

So, we have

h ≥ -14

-v/2 ≤ 9.5

Multiply both sides by -2

v ≥ -19

-4/5m ≥ -8

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.

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

Answer:

Step-by-step explanation:

The equality property that justifies the statement "If m∠ 1=25 and m∠2=25 , then m∠1=m∠2" is; Substitution Property

The substitution property of equality states that 'If a variable C is equal to another variable D, then C can be substituted in place of D in any equation/expression and D can be substituted in place of C in any equation/expression.

Now, we are given the expressions;

If m∠ 1  = 25 and m∠2 = 25 , then m∠1 = m∠2.

Thus, we can also say that the property used here is called substitution property because the parameters were interchanged and still equal.
