I you place the 37 foot ladder against the top of the 15 foot building, it will reach a height of 52 feet.

If you place a 37 foot ladder against the top of a 15 foot building, then the ladder will reach a height of 52 feet (37+15=52). To calculate this, you can use the formula for addition, which is x + y = z, where x is the height of the building, y is the height of the ladder, and z is the total height the ladder will reach. In this case, x = 15 and y = 37, so the total height the ladder will reach will be z = 15 + 37 = 52. This means that if you place the 37 foot ladder against the top of the 15 foot building, it will reach a height of 52 feet.

The expression (x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) when simplified is 2x + 4

Given that

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7)

To start with, we factorize the factors of the expression

The factored expressions are

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) = (x + 2)(x + 7)/(2x) * x(x - 4)/(x - 7)(x + 7) ÷ (x-4)/(x-7)

Cancel out the common factors to reduce the expression

So, we have

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) = (x + 2)/(2) * (x - 4)/(x - 7) ÷ (x-4)/(x-7)

Express division as product

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) = (x + 2)/(2) * (x - 4)/(x - 7) * (x - 7)/(x - 4)

Evaluate the quotient

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) = (x + 2)/(2)

So, we have

(x² + 9x + 14)/(2x) * (x² - 4x)/(x² - 49) ÷ (x-4)/(x-7) = 2x + 4

After approximately 9.95 years, the employee will be earning $10.00 per hour.

What is property of logarithms?

The properties of logarithms are a set of rules that can be used to manipulate logarithmic expressions, including the product, quotient, power, and change of base properties.

We are given that the employee's hourly wage after t years is given by the equation [tex]y=7.03(1.03)^t[/tex]. We need to find the amount of time t after which he will be earning $10.00 per hour. So we set y = $10.00 and solve for t as follows:

$10.00 = $[tex]7.03(1.03)^t[/tex]

Divide both sides by $7.03:

1.4246 = [tex]1.03^t[/tex]

Take the natural logarithm of both sides:

ln(1.4246) = ln([tex]1.03^t[/tex])

Using the property of logarithms that ln([tex]a^b[/tex]) = b * ln(a), we can simplify the right-hand side:

ln(1.4246) = t * ln(1.03)

Answer: To find the image of point L(-4,3) after a dilation with a scale factor of 3 and center at the origin, we need to multiply the coordinates of point L by the scale factor.

The formula for dilation is:

(x', y') = (kx, ky)

where (x, y) are the original coordinates, (x', y') are the coordinates of the image, and k is the scale factor.

In this case, k = 3 and the coordinates of point L are (-4, 3).

So,

x' = kx = 3(-4) = -12

y' = ky = 3(3) = 9

Therefore, the image of point L(-4, 3) after the dilation with a scale factor of 3 and center at the origin is (-12, 9).

As portrayed in the show, his biggest flaw is not knowing how to be a man. He had spent his life avoiding her responsibility, but she came anyway. He unnecessarily bows to Daenerys after she agrees to fight the Night King.

Perhaps Jon's biggest lingering flaw can be seen in book five: he's not a very good communicator. He struggled to sell his long-term ideas to his subordinates, and he also struggled to balance being overly friendly with them and alienating them, and he chose the latter. Other characters portray him as gruff, hard to read, and lacking in articulation, which isn't great when you're trying to bring about sweeping social reform. This is especially serious when you are dealing with people who are ready to kill you to prevent the implementation of the aforementioned social reforms.

I always say that Robb and Jon have the opposite problem: Robb is very good at selling himself, selling his ideas and thinking short term.

Jon is better at long-term strategic thinking and big-picture thinking, but lacks Robb's ability to really bring people to him.

Then of course, perhaps paradoxically, you have the underlying temper that he sometimes explodes (think of him heaving Thorne's throat with one hand, strangling Iron Emmett, etc.). He also felt very self-pity and defensive about his half-blood identity, both before and after joining the Night's Watch, while considering himself socially and militarily superior to his brothers in the Night guard. He needs someone to line him up (Donal Nye in the book, Tyrion in the show).

Then you have his flaws, which others might interpret as strengths. Lots of people criticized Jon for getting too involved in politics, like helping Stannis, throwing Creeker Stark in an ice prison, and getting Aryskar Stark to marry Saigon. Effective and ruthless efficiency, in the eyes of some, could on the other hand be described as a senseless (insidious?) intervention, the Pink Letter is Jon's intervention, which catches up with him. I also don't think the fictional character Harry Potter is that exciting.

To find the principal, we can use the formula:

Total Interest = (Principal x Rate x Time) / 100

Where,

Rate = Annual Rate of Interest

Time = Period in years

Plugging in the given values, we get:

1222 = (Principal x 6.5 x 4) / 100

Simplifying the equation:

1222 = (26 x Principal) / 10

Each year, the wild turkey population, which was once 250, drops by 2.2%. There will be around 209 turkeys left after 8 years.

Wild turkey populations are declining at a 2.2% annual pace. The initial population of 250 turkeys is anticipated to drop to around 209 turkeys after 8 years. Using the exponential decay formula, we can determine the rate of decline annually: P is the population at a certain moment, P0 is the starting population, r is the rate of reduction expressed as a decimal, and t is the time in years. P = P0 (1 - r)t. The answer to the r equation is r = (1 - (P/P0)(1/t)) = 0.022. As a result, the population is declining by 2.2% annually.

The area of a parallelogram can be obtained from the formula for a rectangle by using the same base and height, leading to the formula Area of parallelogram = base x height.

By moving the red triangle to the green triangle, we create a rectangle with the same base and height as the original parallelogram. Therefore, the area of the original parallelogram is equal to the area of the rectangle, which is given by the formula:

Area of rectangle = base x height

We can conclude that the formula for the area of a parallelogram is also given by:

Area of parallelogram = base x height

This is because a parallelogram can be divided into two congruent triangles, and the area of each triangle is half the area of the parallelogram. Therefore, the area of a parallelogram is equal to the base times the height, which is the same as the formula for the area of a rectangle.

The true statement is that (x + 3) is a factor of f(x) = x³ + 3x² - x - 3 since f(-3) = 0.

A polynomial is an expression that consists of variables, terms, exponents and constants.

The factors are the polynomials which are multiplied to produce the original polynomial.

The factorisation of a polynomial is breaking the polynomial as a products.

Therefore,

f(x) = x³ + 3x² - x - 3

Hence, let's use the factor (x + 3)

Therefore,

f(-3) = (-3)³ + 3(-3)² - (-3) - 3

f(-3) = -27 + 27 + 3 - 3

f(-3) = 0

What is the probability that at least 8 fail the test?To find the probability that at least 8 fail the test, we will use the binomial probability formula.The binomial distribution is a statistical distribution that describes the probability of success or failure in an experiment or survey with two possible outcomes.Suppose a trial consists of n independent experiments, each of which has two possible outcomes: either success with probability p or failure with probability q = 1 – p. If X is the number of successes in n trials, then X is said to follow a binomial distribution with parameters n and p. The probability that X = x is given by;P(X = x) = nCxpx(1-p)n-xwhere nCx = n! / x! (n-x)! is the binomial coefficient which counts the number of ways that x successes can be chosen from n trials.Using the formula, we have;P(X >= 8) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15)Here n = 15, p = 0.2 and q = 0.8P(X >= 8) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15)= 15C8 (0.2)^8 (0.8)^7 + 15C9 (0.2)^9 (0.8)^6 + 15C10 (0.2)^10 (0.8)^5 + 15C11 (0.2)^11 (0.8)^4 + 15C12 (0.2)^12 (0.8)^3 + 15C13 (0.2)^13 (0.8)^2 + 15C14 (0.2)^14 (0.8)^1 + 15C15 (0.2)^15 (0.8)^0= 0.0094 + 0.0267 + 0.0524 + 0.0864 + 0.1174 + 0.1312 + 0.1184 + 0.0352= 0.5771Therefore the probability that at least 8 fail the test is 0.5771 (rounded to four decimal places).Answer: 0.5771

the selling price as a percent of cost is 120.52%, b- the selling price is $508.20 and the markup is 20.95% of cost.

(a) To find the selling price as a percent of cost, we need to first find the selling price and then divide it by the cost and multiply by 100%.

The markup on cost is 21%, which means the dealer sells the part for:

420 + 0.21*420 = $508.20

So the selling price is $508.20 and the cost is $420.

The selling price as a percent of cost is:

508.20/420 * 100% = 120.52%

So the selling price is 120.52% of the cost.

(b) The selling price is $508.20.

(c) The markup is the difference between the selling price and the cost, expressed as a percentage of the cost:

Markup = (Selling price - Cost)/Cost * 100%

Using factor theorem, we have(f(x) = x³ - 10x² + 27x - 18)(x - 2) is a factor of f(x)if and only if f(2) = 0.So, we have f(2) = 2³ - 10(2²) + 27(2) - 18 = 0. Therefore, (x - 2) is a factor of f(x) and we can find the other two roots by factorizing the cubic function. Using long division method, we get f(x) = (x - 2)(x² - 8x + 9) Now, to find the other two roots, we solve the quadratic equation x² - 8x + 9 = 0 using the quadratic formula. x = (-b ± √(b² - 4ac))/2a. We have a = 1, b = -8 and c = 9. Substituting the given values in the above formula, we get x = (8 ± √(8² - 4(1)(9)))/2= (8 ± √28)/2= 4 ± √7.
