Case 10: x = 3√2, y = 2√6

Case 11: x = √10, y = 2√5

Case 12: x = 4√7, y = 8√21

Herein we find twelve cases of special right triangles whose missing sides must be determined by using the following rules:

45 - 90 - 45 Right triangle

r = √2 · x = √2 · y

30 - 60 - 90 Right triangle

x = (1 / 2) · r

y = (√3 / 2) · r = √3 · x

Where:

Case 1

y = √2 · 13

x = 13

Case 2

x = y = 15√2

Case 3

x = 3 / (1 / 2)

x = 6

y = 3√3

Case 4

x = 34 · (√3 / 2)

x = 17√3

y = 34 · (1 / 2)

y = 17

Case 5

x = y = 10

Case 6

x = 25√3 / (√3 / 2)

x = 50

y = 25√3 / √3

y = 25

Case 7

x = y = 2√14 · √2 = 2√28 = 4√7

Case 8

x = 24 / (√3 / 2)

x = 48 / √3

x = 16√3

y = 24 / √3

y = 8√3

Case 9

x = 22√3 · (1 / 2)

x = 11√3

y = 22√3 · (√3 / 2)

y = 33

Case 10

x = √18

x = 3√2

y = √6 / (1 / 2)

y = 2√6

Case 11

x = √10

y = √20

y = 2√5

Case 12

x = 4√21 / √3

"Games played in a workplace environment to achieve status, advancement and money"

If we express  \(3x^2-6x-2\) in the form  \(a(x-h)^2+k\), then a + h + k = -1

The given quadratic expression is:

\(3x^2-6x-2\)

To express \(3x^2-6x-2\) in the form \(a(x-h)^2+k\), follow the steps below

Rewrite \(3x^2-6x-2\) as  \(3x^2-6x+3-5\)

Factorize common terms

\(3(x^2-2x+1)-5\)

This can be further simplified as:

\(3(x-1)^2-5\)

Therefore, the vertex form of the equation  \(3x^2-6x-2\) is \(3(x-1)^2-5\)

Compare \(3(x-1)^2-5\) with  \(a(x-h)^2+k\)

a = 3, h = 1, k = -5

a  +  h  +  k  =  3  +  1 - 5

a  +  h  +  k  =  -1

Therefore if we express  \(3x^2-6x-2\) in the form  \(a(x-h)^2+k\), then a + h + k = -1

So, subtracting the same number, multiplying each side by the same non-zero number, and squaring each side of an equation will always give you an equivalent equation.

(a) Subtracting the same number from each side of an equation always gives an equivalent equation. True.

When you subtract the same number from both sides of an equation, you are essentially balancing the equation. This means that whatever you do to one side, you must also do to the other side in order to maintain equality.

For example, let's say we have the equation:

2x + 5 = 10

If we subtract 5 from both sides, we get:

2x = 5

The equation is still equivalent because we subtracted the same number from both sides, maintaining the balance.

(b) Multiplying each side of an equation by the same non-zero number always gives an equivalent equation. True.

When you multiply each side of an equation by the same non-zero number, you are again maintaining the balance between the two sides of the equation.

For example, let's say we have the equation:

3x = 9

If we multiply both sides by 2, we get:

6x = 18

The equation is still equivalent because we multiplied both sides by the same non-zero number, maintaining the balance.

(c) Squaring each side of an equation always gives an equivalent equation. True.

When you square each side of an equation, you are applying the squaring operation to both sides. This operation maintains the equality between the two sides.

For example, let's say we have the equation:

2x = 4

If we square both sides, we get:

(2x)^2 = 4^2

4x^2 = 16

The equation is still equivalent because we squared both sides, maintaining the balance.

In summary, subtracting the same number, multiplying each side by the same non-zero number, and squaring each side of an equation will always give you an equivalent equation.

The car that cost $\($35750\) in \(2014\) will be valued $\(14,919.48\) in \(2022\) if the annual depreciation rate is \(10.5%\)%

The depreciation rate is the percentage at which an object depreciates over its anticipated useful life.

It can also be described as the portion of an organization's long-term investment in an asset that the organization claims as a tax-deductible expenditure over the course of the asset's useful life.

Given.

Value for the \(1\)st Year (\(2014-2015\)) is $ \($35,750\) -$(\(350,750*10.5\)%) =

$\(31,981.25\)

The values of log5, log3, and log19 are not provided, we cannot determine the exact value of log57 without this information.

We can use the logarithm properties to find the value of log57 given that log75 is 0.83.

One of the logarithm properties states that:

log(a * b) = log(a) + log(b)

Using this property, we can express log57 in terms of log75:

log57 = log(5 * 3 * 19)

Now, we can use the fact that log75 is 0.83 to find log5, log3, and log19, and then add them together to get the value of log57:

log57 = log(5 * 3 * 19)

log57 = log5 + log3 + log19

However, since the values of log5, log3, and log19 are not provided, we cannot determine the exact value of log57 without this information.

To find log57 using the given information log75 = 0.83, we can use the change of base formula:  

if log75 = 0.83, then log57 ≈ 0.827. To find log57 using the given information log75 = 0.83, we can use the change of base formula:log_b(a) = log_c(a) / log_c

Here, we want to find log57 (log_7(5)) using the given information log75 (log_5(7)).

We can rewrite the change of base formula as:log_7(5) = log_x(5) / log_x(7)We know that log_5(7) = 0.83,

so we can substitute this value into the equation:log_7(5) = log_x(5) / 0.83

Now we can use any common base, like base 10 or base e, to find the value of log_7(5). Let's use base 10:log_7(5) = log_10(5) / log_10(7)Now

we can calculate the values of log_10(5) and log_10(7) using a calculator:log_10(5) ≈ 0.69897log_10(7) ≈ 0.84510

Now substitute these values back into the equation:log_7(5) = 0.69897 / 0.84510Now divide to get the value of log_7(5):log_7(5) ≈ 0.82706So, if log75 = 0.83, then log57 ≈ 0.827.

Answer:

Gustavo used a simulation where the data is quantitative’

The number of ways the 17 guests can arrange themselves on a five-person couch can be determined using the concept of permutations.

To calculate the number of ways the guests can arrange themselves on the couch, we can consider each seat on the couch as a position to be filled by a guest.
Since the couch can accommodate only five guests, we need to select five guests out of the 17 available. The order in which the guests sit matters because different arrangements result in different seating configurations.
The number of ways to select five guests out of 17 can be calculated using the formula for combinations, which is denoted as "n choose r" or nCr. In this case, we need to calculate 17C5.
Using the formula for combinations, we have:
17C5 = 17! / (5!(17-5)!)
= 17! / (5!12!)
= (17 * 16 * 15 * 14 * 13) / (5 * 4 * 3 * 2 * 1)
= 6188
Therefore, there are 6188 ways in which the 17 guests can arrange themselves on the five-person couch.

(x + 2)^2 + (y + 5)^2 = 1

Step-by-step explanation:

Since this circle is centered at (-2, -5), we have to add values within the squares. The standard form of a circle equation is:

(x - h)^2 + (y - k)^2 = r^2

So -2 is h and -5 is k. Substituting that in we get:

(x + 2)^2 + (y + 5)^2 = r^2

We are given the radius is 1, and one squared is one, so the final equation is:

(x + 2)^2 + (y + 5)^2 = 1

In general, to evaluate the function f(x) at a specific value of x, we substitute that value into the expression for f(x) and simplify.

In mathematics, a function is a relation between two sets, where for every element in the first set (called the domain), there is exactly one element in the second set (called the range) that the function maps to. In simpler terms, a function is a rule that assigns each input value from the domain to exactly one output value in the range. Functions are usually represented by a formula or equation that describes the relationship between the input and output values. For example, the function f(x) = 2x + 1 maps every input value of x to an output value that is twice the input value plus 1.

Here,

To evaluate the function f(x) = 4x - 6, we substitute the given values of the independent variable into the expression for f(x) and simplify.

For example:

f(0) = 4(0) - 6 = -6

f(1) = 4(1) - 6 = -2

f(2) = 4(2) - 6 = 2

f(-1) = 4(-1) - 6 = -10

The theory of punctuated equilibrium is based on the observation that A) Long periods of intense speciation alternate with long brief periods of stasis.What is the punctuated equilibrium?

The punctuated equilibrium is a theory in evolutionary biology that posits that species tend to remain stable for long periods of time. This theory, in particular, challenges the traditional view that evolutionary change occurs continuously and gradually over time. Instead, it suggests that species change very little over long periods of time punctuated by brief bursts of rapid change.Based on the observation that long periods of intense speciation alternate with long brief periods of stasis, the theory of punctuated equilibrium is a paradigm-shifting theory in the study of evolutionary biology. It has also helped paleontologists, who rely on fossil records, better understand how species evolve over time.

Distribute

-7c*.6 + 8d * .6

-4.2c+4.8d

Answer:

-4.2c + 4.8d

Step-by-step explanation:

We would like to distribute the 0.6 in the expression (-7c + 8d) * 0.6.

Remember that when distributing, we multiply the "outside number" (0.6 in this case) by each of the "inside numbers" (-7c and 8d) and then add those products.

So, the first product will be: 0.6 * (-7c) = -4.2c. The second product will be: 0.6 * 8d = 4.8d. Add these together: -4.2c + 4.8d.

The answer is thus -4.2c + 4.8d.
