Answer: To find the length of the hypotenuse of a right triangle, we can use the Pythagorean theorem, which states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides. The theorem is written as c² = a² + b², where c is the length of the hypotenuse and a and b are the lengths of the other two sides.

In this problem, we are given that the lengths of the legs of the right triangle are 7 inches and 2 inches. We can substitute these values into the Pythagorean theorem and solve for c, the length of the hypotenuse.

So, we have c² = 7² + 2².

So, c² = 49 + 4

So, c² = 53

Now, we can take the square root of both sides of the equation, since c² = 53, we can say c = √53

To round to the nearest tenth, we look at the digit in the thousandths place (the 3rd digit after the decimal point). Since 3 is greater than or equal to 5, we round up, so c = 7.28, so the hypotenuse is 7.28 inches.

Answer:

q=quarters, d=dimes

q+d=8

.25q+.1d=1.25

Let's set the first equation to equal d.

d=8-q

.25q+.1(8-q)=1.25

Distribute.

.25q+.8-.1q=1.25

Combine Like Terms

.15q+.8=1.25

Subtract .8

.15q=.45

Divide by .15

q=3

Now, let's solve for d in the first equation.

d+3=8

Subtract 3, and you get d=5

So, there are 5 dimes and 3 quarters in Maribel's pocket.

Check: .25(3)+.1(5)=1.25

.75+.5=1.25

1.25=1.25 which is true.

Jordan has 3 quarters and 5 dimes in his pocket that total to $1.25.

Let's assume Jordan has x number of quarters and 8 - x number of dimes in his pocket.

Each quarter is worth 25 cents, so the value of the quarters is 25x cents.

Each dime is worth 10 cents, so the value of the dimes is 10(8-x) cents.

The sum of the values of the quarters and dimes should be equal to $1.25, which is 125 cents. So, we can set up the equation: 25x + 10(8-x) = 125.

Simplifying the equation, we get 25x + 80 - 10x = 125. Combining like terms, 15x + 80 = 125. Subtracting 80 from both sides, 15x = 45. Finally, dividing both sides by 15, we find x = 3.

Therefore, Jordan has 3 quarters and 8 - 3 = 5 dimes in his pocket.

Alec's parents give him x dollars per month for his allowance. However, since his birthday is in February, he gets an extra 20% bonus that month. The allowance in February can be represented by the expression x + 0.2x because Alec will get the regular allowance of x dollars plus an extra 20% bonus which is equal to 0.2x dollars.

x + 0.2x = Alec's allowance in February

The expression 1.2x is not correct because it represents Alec's allowance multiplied by 1.2 which is not the same as the allowance plus the bonus.

So the correct answer is x + 0.2x.

Answer:

√104.

Step-by-step explanation:

To find the distance between two points (x1, y1) and (x2, y2) in a coordinate plane, we can use the distance formula:

d = √((x2 - x1)² + (y2 - y1)²)

So, for the given points (5, -4) and (3, 6), the distance is:

d = √((3 - 5)² + (6 - (-4))²)

d = √((-2)² + (10)²)

d = √(4 + 100)

d = √104

Therefore, the distance between the two points (5, -4) and (3, 6) is √104.

An example of two irrational numbers that add up to 2 are √2 and √2 - 2.

√2 is an irrational number as it cannot be expressed as a ratio of two integers.

√2 - 2 is also an irrational number as it is the difference of two irrational numbers.

Both √2 and √2 - 2 are irrational numbers and √2 + (√2 - 2) = √2 + √2 - 2 = 2

So, √2 and √2 - 2 are two irrational numbers that add up to 2.

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.

minus 3 from both sides:

5w=-10 then divide both sides by 5 to go get w by it self

w=-2

The value of w is -2.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given is an equation with 1 variable w.

5w + 3 = -7

We have to find the value of w.

We need to get the variable w on the left hand side and a number on the right hand side of the given equation.

Subtracting both sides of the equation by -3,

5w + 3 - 3 = -7 - 3

5w = -10

Dividing both sides of the equation by 5,

5w/5 = -10/5

w = -2

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

Step-by-step explanation:

An equation for a rational function with the given characteristics is  f(x)=3/2 (x+3)(x-3)/(x+2)(x-2)

A relation is a function if it has only One y-value for each x-value.

Since there are vertical asymptotes at X = -2 and X = 2, the denominator will have the terms (x+2) and (x-2)

Since the x intercepts are -3 and 3, the numerator will have the terms (x+3) and (x-3)

So far we have f(X) = a(x+3)(x-3)/(x+2)(x-2)

o find the value of A, we look at the horizontal asymptote. The horizontal asymptote describes what the function looks like when x approaches infinity, therefore a = 3/2

f(x)=3/2 (x+3)(x-3)/(x+2)(x-2)

Hence, an equation for a rational function with the given characteristics is  f(x)=3/2 (x+3)(x-3)/(x+2)(x-2)

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 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,

SI=P*r*t

Step-by-step explanation:

This statement is true because the probability of Player 2, which is five eighths, is greater than the probability of Player 1, which is four sevenths. It is important to note that in order to compare the probabilities, it is necessary to convert the fractions to a common denominator. In this case, the common denominator is 56, then we can say that P(Player 2) = 35/56 and P(Player 1) = 28/56. Since 35/56 > 28/56, it is more likely that Player 2 will hit the ball than player 1.

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.

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.
