Answer:

I hope this will be all right

Answer: I hope this will be right

Firstly, we know that when you rhyme, the ending word must sound the same.

In this case, the most recent word in the poem is "plight"

Let's look at the ending words of choices and see what rhymes with "plight".

A. I hope this will be "right"

B. Why does my teacher deceive "me"

C. I don't know how to write a poem and make it "rhyme"

Here you can see that the only word that rhymes with "plight" is "right".

Second, it has to relate to the poem that is given as much as possible.

The letter "A" both rhymes and relates to the given poem.

The last thing you need to know is the length of the sentence for the poem. In choice "C", it is way too long, making "C" incorrect.

Choice "B" isn't very long, but the number of syllables is also too many.

When writing a poem like this, you want to make the number of syllables as close as you can. In this case, the number of syllables on the bottom sentence is 7, and choice "A", and "I hope I get this right" has 6 syllables, therefore, choice "A" is the correct answer, and it matches all the necessities needed for completing the poem.

Answer:

The two people are 15 meters far apart.

Right angled triangle are those triangle for which one of the angle is 90 degrees.

Pythagoras Theorem says that, for a triangle which is right, the sum of the squares of base and altitude is equal to the square of hypotenuse.

Here if a person travels north and other person travels east, there forms a right triangle by connecting the end points of the position of two persons.

We have to find hypotenuse.

Base = 9 meters and Altitude = 12 meters

Hypotenuse² = Base² + Altitude²

                      = 9² + 12²

I can earn simple interest $12 in 6 years and My friend can earn simple interest $12 in 4 years.

What is simple interest?

The principal of a loan or the initial deposit into a savings account serves as the foundation for simple interest. Because simple interest doesn't compound, a creditor will only pay interest on the principal sum, and a borrower will never have to pay interest on the interest that has already accrued.

Principle = $50

Rate of Interest I1 = 4%

Interest = $12.

Interest = [tex]\frac{PNR}{100}[/tex]

=> 12 = [tex]\frac{50\times 4\times N}{100}[/tex]

=> N = [tex]\frac{12}{2}= 6[/tex] years.

Rate of Interest I2 = 6%

=> 12 = [tex]\frac{50\times 6\times N}{100}[/tex]

=> N = [tex]\frac{12}{3}[/tex] = 4 years.

Hence I can earn $12 in 6 years and My friend can earn $12 in 4 years.

Step-by-step explanation:

you understand how exponents work, right ?

an exponent defines how often its base has to be multiplied by itself.

so,

(-1 + 3i)⁵

means that

(-1 + 3i)

is multiplied 5 times by itself.

and that means we can split this into sub-multiplication groups like

(-1 + 3i)²×(-1 + 3i)²×(-1 + 3i) = (-1 + 3i)⁴×(-1 + 3i)

the advantage is that squares are easily calculated.

(a + b)² = a² + 2ab + b²

so,

(-1 + 3i)² = (-1)² + 2×-1×3i + (3i)² = 1 - 6i - 9 = -8 - 6i

(-1 + 3i)²×(-1 + 3i)² = ((-1 + 3i)²)² = (-8 - 6i)² =

= (-8)² + 2×-8×-6i + (-6i)² = 64 + 96i - 36 = 28 + 96i

(-1 + 3i)⁵ = (28 + 96i)(-1 + 3i) = -28 + 84i - 96i - 288 =

The growth/decay rate of an exponential function can be found by taking the derivative of the function with respect to the independent variable.

K in terms of growth and decay?

The growth rate is represented by the constant k. When viewed in terms of exponential DECAY, it is NEGATIVE. The length of time since then is t. If the time information is provided as dates, you must convert it to the amount of time that has passed from the starting point.

Given the function f(x) = 5(1.34)^t, the derivative with respect to t is:

f'(x) = 5(1.34)^t * ln(1.34)

The derivative represents the instantaneous rate of change of the function, and it is also the growth/decay rate.

So the growth/decay rate of the function f(x) = 5(1.34)^t is 5ln(1.34) * (1.34)^t.

In this function, the growth/decay rate is directly proportional to the function value, and it is a constant times the function value. This means that the function is growing or decaying at a constant rate, the rate being 5ln(1.34) which is the coefficient of (1.34)^t.

This constant rate of change is the growth/decay rate. In this case it is a growth rate of 5ln(1.34) which is approximately 1.99.

The required value of the given equation is p = √3 + 8.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

If we let x = p - 8, then p = x + 8 and p × p = (x + 8) × (x + 8) = x² + 16x + 64.

We can substitute this expression for p × p in the given equation to get x^2 + 16x + 64 = (8 × (x + 8)) + 3 = 8x + 64 + 3 = 8x + 67.

Subtracting 64 from both sides gives us x² + 16x = 8x + 3, and if we subtract 8x from both sides, we get x² = 3.

The only positive value of x that satisfies this equation is x = √3, so p = √3 + 8.

Since √3 is approximately 1.73, p is approximately 9.73, which is greater than 4.

Therefore, a value of p that satisfies the given equation is p = √3 + 8.

Answer:

y = - [tex]\frac{2}{5}[/tex] , y = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

10y² - 11y - 6 = 0

consider the factors of the product of the y² term and the constant term which sum to give the coefficient of the y - term

product = 10 × - 6 = - 60 and sum = - 11

the factors are - 15 and + 4

use these factors to split the y- term

10y² - 15y + 4y - 6 = 0 ( factor the first/second and third/fourth terms )

5y(2y - 3) + 2(2y - 3) = 0 ← factor out (2y - 3) from each term

(2y - 3)(5y + 2) = 0 ← in factored form

equate each factor to zero and solve for y

5y + 2 = 0 ⇒ 5y = - 2 ⇒ y = - [tex]\frac{2}{5}[/tex]

2y - 3 = 0 ⇒ 2y = 3 ⇒ y = [tex]\frac{3}{2}[/tex]
