Answer:

x^3 + 2x^2 + 4x - 8

Step-by-step explanation:

To find the product of (x-2)(x^2+2x+4), we can use the distributive property.

(x-2)(x^2+2x+4) = x(x^2+2x+4) - 2(x^2+2x+4)

= x^3 + 2x^2x - 2x^2 - 4x - 8

= x^3 + 2x^2 + 4x - 8

Answer:

You must apply the distributive principle x3 + 2x2 + 4x - 8 (x-2)(x2+2x+4) = x(x2+2x+4) - 2(x2+2x+4) to obtain the product of (x-2)(x2+2x+4).

So, therefore it is

= x^3 + 2x^2x - 2x^2 - 4x - 8

= x^3 + 2x^2 + 4x - 8

(See attachment).

Given:

Convert 9600 meters into kilometers by dividing by 1000:

⇒ 9600 m = 9600 ÷ 1000 = 9.6 km

[tex]\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]

Therefore:

[tex]\sf Time=\dfrac{Distance}{Speed}[/tex]

Substitute the given distance and speed into the formula to calculate the time it took Kendra to walk from K to L:

[tex]\implies \sf Time=\dfrac{9.6\;km}{4.5\;km/h}=2.133333...\;hours[/tex]

Convert 2.133333.. into a mixed number:

[tex]\implies \sf 2.133333...=2\frac{2}{15}\;hours[/tex]

To find the number of minutes in 2/15ths of an hour, multiply 2/15 by 60:

[tex]\implies \sf \dfrac{2}{15} \times 60=\dfrac{120}{15}=8\;minutes[/tex]

Therefore, it took Kendra 2 hours and 8 minutes to walk from K to L.

If Kendra left at 10:15:

[tex]\implies \sf 10:15 + 2\;hours = 12:15[/tex]

[tex]\implies \sf 12:15 + 8\;minutes=12:23[/tex]

Therefore, Kendra arrived at L at 12:23.

Answer:

- 8, - 6, - 4, - 2, 0

Step-by-step explanation:

the term- to- term rule

[tex]u_{n+1}[/tex] = [tex]u_{n}[/tex] + 2

means that to find a term in the sequence you add 2 to the previous term.

given u₃ = - 4 , then

u₄ = u₃ + 2 = - 4 + 2 = - 2

u₅ = u₄ + 2 = - 2 + 2 = 0

to find the first 2 terms, rearrange the rule as

[tex]u_{n+1}[/tex] = [tex]u_{n}[/tex] + 2 ( subtract 2 from both sides )

[tex]u_{n+1}[/tex] - 2 = [tex]u_{n}[/tex] , that is

[tex]u_{n}[/tex] = [tex]u_{n+1}[/tex] - 2

this allows for a term to be found by subtracting 2 from the next term, so

a₂ = a₃ - 2 = - 4 - 2 = - 6

a₁ = a₂ - 2 = - 6 - 2 = - 8

the first 5 terms are then : - 8, - 6, - 4, - 2, 0

Two lines are parallel if their slopes are equal. To find the slope of the line through the points (1,2) and (1,a), we can use the formula:

(y2 - y1) / (x2 - x1) = (a - 2) / (1 - 1) = a - 2

To find the slope of the line 6x + 2y = -2, we can rewrite it in slope-intercept form (y = mx + b) by isolating y:

2y = -6x - 2

y = -3x - 1

So the slope of this line is -3.

Since the line through the points (1,2) and (1,a) is parallel to 6x + 2y = -2, we know that the slopes must be equal. Therefore:

a - 2 = -3

Solving for a:

a = -1

So the value of a is -1.

The interest paid at the term end will be $5400.

What is interest and its types(Simple and compound interest)?

Interest is the cost of borrowing money, where the borrower pays a fee to the lender for the loan. The interest, typically expressed as a percentage, can be either simple or compounded. Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period. Simple interest is calculated only on the principal amount of a loan or deposit, so it is easier to determine than compound interest.

​The formula for these are

Simple Interest= P×r×n

where:

P=Principal amount

r=Annual interest rate

n=Term of loan, in years

​

Compound Interest=P×(1+r)^t−P

where:

P=Principal amount

r=Annual interest rate

t=Number of years interest is applied

​

Here,

Interest rate will be risk percentage + LIBOR

i.e.4.8%

Hence, the interest can be found by using formula for simple interest

Therefore,

The unitary method is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

Multiplying in math is the same as adding equal groups. The number of items in the group grows as we multiply. Parts of a multiplication issue include the product, the two factors, and the product. The components in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the result is the number 54.

Let x be the number of seats for the second aircraft.

The first aircraft has x + 64 seats.

The third aircraft has 2x - 152 seats.

The total number of seats for all aircraft is x + (x + 64) + (2x - 152) = 1900.

Therefore, 3x = 2064, so x = 688.

The first aircraft has 688 + 64 = 752 seats.

The third aircraft has 2(688) - 152 = 1224 seats.

Answer:

d. x-700=35

Step-by-step explanation:

The statement says that the variations will stay within a range of +5%, so the resistance can be increased by 5% of 700 ohms. To find the highest resistance that can be achieved, you can use the formula:

x = 700 + (700 * 5%) = 700 + 35 = 735 ohms

To find the lowest resistance that can be achieved, you can subtract the same percentage (5%) of 700 ohms:

x = 700 - (700 * 5%) = 700 - 35 = 665 ohms

So the lowest and highest resistance that can be achieved are 665 ohms and 735 ohms respectively.

a) Before the loan is taken out and the investment is made, Karson's times' interest earned ratio is 2.63 times.

b) When the loan and the investment are made, the firm's times interest earned ratio will increase from 2.63 times to 2.87 times.

The times' interest earned ratio is the ratio that measures the company's ability to meet debt obligations using its net operating income.

The interest earned ratio is computed as the quotient of the net operating income (earnings before interest and taxes) and the interest expense.

Current net operating income = $503,000

Interest expense = $191,000

Times interest earned = 2.63 times ($503,000/$191,000)

Proposed loan = $1.15 million

Interest rate = 11%

Interest amount = $126,500 ($1,150,000 x 11%)

Additional net operating income = $408,000

New net operating income = $911,000 ($503,000 + $408,000)

New interest expense = $317,500 ($191,000 + $126,500)

Adjusted Times interest earned = 2.87 times ($911,000/$317,500)

Thus, if Karson takes the additional loan to finance the investment, its times' interest-earned ratio will increase, showing that it has the ability to settle the debt obligations.

The population of Australia in 2018 was 24.909 million.

Given: The population of Sydney in 2018 = 5.48 million

           This population of Sydney is equal to 22 % of the total population of Australia.

To find: Total population of Australia

Solution:

According to the Question,

Total population of Australia * 22% = total population of Sydney

Total population of Australia * 22/100  = 5.48 million

                                                                = 5.48 million * 100/22

                                                                = 24.909 million (approx.)

Hence, the population of Australia in 2018 was 24.909 million.

The total population of Australia in 2018 was 24.90 million.

A percent is a dimensionless number, meaning that it has no units of measurement, since it represents a part of whatever whole is being measured.

Given that, the population of Sydney was 5.48 million, which was 22% of the total population of Australia.

We need to find the total population of Australia.

Let the total population of Australia be y.

Therefore,

y × 22% = 5.48

y = 5.48 × 100/22

y = 24.90

Hence, the total population of Australia in 2018 was 24.90 million.

Answer:

The Riemann Hypothesis is a conjecture made by mathematician Bernhard Riemann in 1859 that states that all non-trivial zeroes of the Riemann zeta function, which is a complex function that encodes the distribution of prime numbers, lie on the critical line of 1/2. The conjecture is considered one of the most important unsolved problems in mathematics and has yet to be proven or disproven.

There have been many efforts to prove the Riemann Hypothesis over the years, but so far, no one has been able to provide a definitive proof. Many mathematicians have made significant progress in understanding the conjecture and its implications, but a proof remains elusive.

Some of the notable efforts to prove the Riemann Hypothesis include:

In 1859, Riemann himself provided evidence to support the conjecture by showing that the first few non-trivial zeroes lie on the critical line.

In 1911, the mathematician G.H. Hardy proved that an infinite number of non-trivial zeroes lie on the critical line.

In the 1970s, the mathematician A. Selberg proved that an infinite number of non-trivial zeroes lie in the critical strip, which is a slightly wider region around the critical line.

Despite these advances, a proof of the Riemann Hypothesis remains elusive and it continues to be one of the most important unsolved problems in mathematics. Some of the most recent and notable progress on the Riemann Hypothesis has been made by researchers using computational methods such as the Turing method and the Gram-Schmidt orthogonalization method, but the proof is not yet proven.

It's worth mentioning that the Riemann Hypothesis is considered an important problem in mathematics, and solving it could have far-reaching implications for many areas of mathematics and physics, including number theory, cryptography and prime number distribution.
