Answer 1

Answer:

a. 73°

b. 98°

Step-by-step explanation:

In quadrilateral EFGH

∡E+∡G=180° sum of opposite angle of quadrilateral inside the circle is 180°

substituting value

11x+8+8x+1=180°

19x+9=180°

19x=180=9

19x=171

x=171/19

x=9°

similarly,

∡H+∡F=180° sum of opposite angle of quadrilateral inside the circle is 180°

substituting value

6y-4+5y-3=180°

11y-7=180°

11y=180°+7

11y=187°

y=187/11

y=17°

Now

a. m∡G=8x+1=8*9+1=73°

b. m∡H=6y-4=6*17-4=98°

Do the ratios 1/3 and 28/36 form a proportion?

Answers

No, they are not proportional!

No, the given two fractions/ratios do not form a proportion.

Two ratios are said to be forming proportions if and only if the reduced forms of fractions of the two ratios are the same or are equal to each other.  For example - [tex]\frac{3}{6}[/tex] and [tex]\frac{1}{2}[/tex] are in proportion because [tex]\frac{3}{6}[/tex] when reduced to the simplest form gives [tex]\frac{1}{2}[/tex] which is the same as the other given ratio.

In the given question, one ratio given is [tex]\frac{1}{3}[/tex] and the other one is [tex]\frac{28}{36}[/tex]. Reducing the second ratio to the simplest form we get [tex]\frac{7}{9}[/tex]. Clearly, the two fractions are not equal. Hence, the given two ratios are not in proportion.

What is the meaning of "Once we give up the full Comprehension Schema, Russell’s Paradox is no longer a threat"?

Answers

The statement "Once we give up the full Comprehension Schema, Russell's Paradox is no longer a threat" implies that by leaving out the unrestricted version of the Schema of Comprehension (which gives room for the construction of sets based on any property), one can be able to avoid meeting up Russell's Paradox.

What is the meaning of the phrase?

Russell discovered the contradiction that arises when analyzing the collection of sets that lack themselves as components. A contradiction arises due to the paradoxical situation of attempting to ascertain if the set includes itself or not.

By adopting the Subset Schema, which limits the creation of sets based on certain criteria, we can steer clear of the paradox and depart from the comprehensive Comprehension Schema.

What is the meaning of "If Y = ran(f), then f is a function onto Y"?

Answers

The statement implies that the function f has a surjective property, ensuring full coverage of the target set Y.

The statement "If Y = ran(f), then f is a function onto Y" can be understood in the context of mathematical functions and their range.

In mathematics, a function is considered "onto" or "surjective" if every element in the target set (in this case, Y) has a pre-image in the domain set. In other words, for every element y in Y, there exists at least one element x in the domain set such that f(x) = y.

The given statement is saying that if Y is equal to the range of the function f, then f is a function that covers or maps onto every element in Y. In this case, the function f has a mapping for each element in the set Y, ensuring that no element in Y is left without a pre-image in the domain set.

Thus, the statement implies that the function f has a surjective property, ensuring full coverage of the target set Y.

Answers

Absolute value is a mathematical function that gives the distance of a number from zero on the number line.

How to explain the information

Let's find the absolute value of the given numbers:

|17| = 17

|−25| = 25

|−1.23| = 1.23

|0.45| = 0.45

Now, let's identify whether the following numbers are rational or irrational:

234: This is a rational number because it can be expressed as a fraction (e.g., 234/1).

5–√: This is an irrational number because it cannot be expressed as a fraction or a ratio of integers. The square root of 5 is not a perfect square, so it is irrational.

To convert the decimal 0.44444... to a fraction, we can set it as the variable x and solve the equation:

x = 0.44444...

Multiply both sides by 10 to move the decimal point:

10x = 4.44444...

10x - x = 4.44444... - 0.44444...

9x = 4

Divide both sides by 9:

x = 4/9

Therefore, the decimal 0.44444... is equivalent to the fraction 4/9.

Matching the numbers with their classifications:

0.3333...: This is a repeating decimal.

3.48372...: This is a nonrepeating decimal.

I'm going to buy a condo for $80,000 the bank requires a 10% down payment the rest is financed with a 15-year fixed rate mortgage at 3.5% annual interest with monthly payments find my required down payment find the amount of the mortgage find the monthly payment​

Answers

The monthly payment on the 15-year fixed rate mortgage is $515.27.

The bank requires a 10% down payment on the condo price of $80,000.

Down Payment = 10% of $80,000

Down Payment = 0.1 * $80,000

Down Payment = $8,000

Therefore, the required down payment is $8,000.

Amount of the Mortgage:

To find the amount of the mortgage, we subtract the down payment from the condo price.

Amount of Mortgage = Condo Price - Down Payment

Amount of Mortgage = $80,000 - $8,000

Amount of Mortgage = $72,000

Therefore, the amount of the mortgage is $72,000.

Now, Monthly Payment = (Loan Amount x Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate) ^ (-Number of Months))

Monthly Interest Rate = Annual Interest Rate / 12

= 3.5% / 12 = 0.035 / 12

= 0.002917

and, Number of Months = 15 years x 12 months = 180 months

So, Monthly Payment = ($72,000 x 0.002917) / (1 - (1 + 0.002917) ^ (-180))

Monthly Payment ≈ $515.27

(C) 51.1 ft.

What is the law of sines?

The law of sines states that the ratio of the length of a side in a triangle to the sine of the angle facing that side is equivalent for the three sides of a triangle.

The length of the shadow = 20 feet

Angle of elevation to the Sun = 73°

The angles formed by the triangle formed by the tree are;

73°, (90 - 5) = 85°, (180 - 85 - 73) = 22°

Let l represent the length of the tree. The law of sines indicates that we get;

Teresa thought the theoretical possibility of getting a head when flipping a coin was 1/2 when she flipped a coin 150 times she got 95 heads is this what she would have expected

Answers

Teresa's result of 95 heads is slightly higher than what she would have expected, it is still reasonably close to the expected value based on the theoretical probability of getting a head when flipping a fair coin.

Teresa's result of 95 heads in 150 coin flips is slightly higher than what she would have expected if the theoretical possibility of getting a head when flipping a coin was exactly 1/2.

When flipping a fair coin, the probability of getting a head is indeed 1/2, and the probability of getting a tail is also 1/2. Therefore, if we assume that the coin is fair and unbiased, we can use the concept of expected value to determine what Teresa would have expected.

The expected value of a single coin flip can be calculated as follows:

Expected value = (Probability of an outcome) * (Value of the outcome)

In this case, the probability of getting a head is 1/2, and the value of getting a head is 1 (since we are interested in the number of heads). Therefore, the expected value of a single coin flip is:

Expected value = (1/2) * 1 = 1/2

To determine what Teresa would have expected in 150 coin flips, we can multiply the expected value of a single coin flip by the number of flips:

Expected number of heads = (Expected value) * (Number of coin flips)

Expected number of heads = (1/2) * 150 = 75

So, if Teresa had flipped the coin 150 times and the coin was fair, she would have expected to get approximately 75 heads.

However, Teresa obtained 95 heads in her actual experiment. This result is slightly higher than the expected value of 75 heads. It's important to note that, due to the inherent randomness of coin flips, there will always be some variation between the expected and actual results. Flipping a coin 150 times is a relatively small sample size, and it is within the realm of possibility to deviate from the expected outcome.

Therefore, while Teresa's result of 95 heads is slightly higher than what she would have expected, it is still reasonably close to the expected value based on the theoretical probability of getting a head when flipping a fair coin.

The product of the fractions is 1/[(x - 5)(x + 7)]

How to evaluate the product of the fractions

From the question, we have the following parameters that can be used in our computation:

Fraction 1 = (x + 1)/(x² - 25)

Also, we have

Fraction 2 = (x + 5)/(x² + 8x + 7)

So, we have

Product = (x + 1)/(x² - 25) * (x + 5)/(x² + 8x + 7)

When factored, we have

Product = (x + 1)/(x - 5)(x + 5) * (x + 5)/(x + 1)(x + 7)

Evaluate the products

Product = 1/(x - 5) * 1/(x + 7)

What is the meaning of "we shall use in formulas other symbols, namely defined predicates, operations, and constants, and even use formulas informally"?

Answers

The statement indicates that in practical applications, it is common to extend the basic logical language with additional symbols and allow for some degree of informality in the representation of formulas, as long as it is clear that these additional symbols and formulas can be formalized in terms of the basic logical language.

What does the statement mean?

The statement means that when working with formulas in a particular context or domain, it is common to introduce additional symbols beyond the basic logical symbols such as "E" (for existential quantification) and "∧" (for conjunction). These additional symbols can include defined predicates, operations, and constants.

Defined predicates refer to predicates or relations that are defined in terms of other predicates or relations. They can be used to express complex concepts or conditions in a concise manner. For example, in mathematics, one may define a predicate "Prime(x)" to represent the concept of a number being prime.

Operations refer to functions or operations that can be applied to terms or formulas. They allow for combining or manipulating expressions in a meaningful way. For instance, addition, multiplication, and exponentiation are common operations in mathematics.

Constants are symbols that represent specific, fixed values. They can be used to denote specific objects or elements within the domain of discourse. For example, in logic, "0" and "1" can be used as constants to represent the truth values "false" and "true," respectively.

Furthermore, the statement suggests that formulas may be used informally, meaning that they can be expressed or written in a less strict or precise manner. While the informal representation of formulas may be easier to understand or work with, it is understood that each of these formulas can be translated or reformulated in a way that only involves the basic logical symbols (such as "E" and "∧") and the specified nonlogical symbols (such as defined predicates, operations, and constants).

Overall, the statement acknowledges that in practical applications, it is common to extend the basic logical language with additional symbols and allow for some degree of informality in the representation of formulas, as long as it is clear that these additional symbols and formulas can be formalized in terms of the basic logical language.

The solution to the given simultaneous equations using Cramer's rule is x = -1, y = -4.92, z = -1.03.

How to Solve Simultaneous Equation Using Crammer's Rule

To solve the given simultaneous equations using Cramer's rule, we need to find the determinants of various matrices.

Given the set of equation:

3x-3y+ 5z = 5

9x - 8y + 13z = 14

-3x+4y- 7z=-7

We start by finding the determinant of the coefficient matrix, which is denoted as D.

D = [tex]\left[\begin{array}{ccc}3&-3&5\\9&-8&13\\-3&4&-7\end{array}\right][/tex]

To calculate D, we use the formula:

D = (3 * (-8) * (-7) + (-3) * 13 * (-3) + 5 * 9 * 4) - ((-3) * (-8) * 5 + 3 * 13 * 4 + (-3) * 9 * (-7))

D = (-168 + 117 + 180) - (120 - 156 + 189)

D = 129 - 165

D = -36

Next, we need to find the determinants of the matrices obtained by replacing the columns of the coefficient matrix with the constant terms. These determinants are denoted as Dx, Dy, and Dz, respectively.

Dx = [tex]\left[\begin{array}{ccc}5&-3&5\\14&-8&13\\-7&4&-7\end{array}\right][/tex]

Dx = (-40 - 65 + 20) - (-70 - 60 + 189) = -85 - (-121) = -85 + 121

Dx= 36

Dy = [tex]\left[\begin{array}{ccc}3&5&5\\9&14&13\\-3&-7&-7\end{array}\right][/tex]

Dy = (21 + 75 + 35) - (-21 - 130 + 105) = 131 - (-46) = 131 + 46

Dy = 177

Dz = [tex]\left[\begin{array}{ccc}3&-3&5\\9&-8&14\\-3&4&-7\end{array}\right][/tex]

Dz = (39 - 39 + 0) - (-27 + 84 + 20) = 0 - (-37) = 0 + 37

Dz = 37

Finally, we can find the values of x, y, and z using the formulas:

x = Dx / D

y = Dy / D

z = Dz / D

Plugging in the values, we have:

x = 36 / -36 = -1

y = 177 / -36 ≈ -4.92

z = 37 / -36 ≈ -1.03

Therefore, the solution to the given simultaneous equations using Cramer's rule is x = -1, y ≈ -4.92, z ≈ -1.03.

The area under the curve y = x² + 5x + 4 and the x-axis is [tex]1\frac{2}{3}[/tex] square units.

To find the area under the curve y = x² + 5x + 4 and the x-axis, we need to integrate the given function over a specific interval.

We need to find the definite integral of the function over a suitable interval.

Let's find the definite integral of the function from its roots (where the curve intersects the x-axis).

First, let's find the roots of the function by setting y = 0:

x² + 5x + 4 = 0

Factoring the quadratic equation:

(x + 1)(x + 4) = 0

Setting each factor equal to zero:

x + 1 = 0 => x = -1

x + 4 = 0 => x = -4

The roots of the function are x = -1 and x = -4.

To find the area under the curve, we integrate the function from x = -4 to x = -1:

∫[x=-4 to -1] (x² + 5x + 4) dx

Integrating the function:

∫[x=-4 to -1] (x² + 5x + 4) dx = [1/3x³ + (5/2)x² + 4x] from -4 to -1

Substituting the limits:

[1/3(-1)³ + (5/2)(-1)² + 4(-1)] - [1/3(-4)³ + (5/2)(-4)² + 4(-4)]

Simplifying:

[-1/3 + 5/2 - 4] - [-64/3 + 40/2 - 16]

There is a substance called sodium-24 that decays at a rate of 4.5% per hour, compounded continuously.
You start with a sample of 500 grams of this substance.
a) Write a function to model the amount remaining after t hours.

Answers

The function to model the amount remaining after t hours is:

[tex]A(t) = 500 \times e^{-0.045t}[/tex]

We have,

To model the amount remaining after t hours for the substance sodium-24, which decays at a rate of 4.5% per hour compounded continuously, we can use the formula for continuous exponential decay:

[tex]A(t) = A(0) \times e^{-rt}[/tex]

Where:

A(t) is the amount remaining after t hours,

A(0) is the initial amount,

e is the base of the natural logarithm (approximately 2.71828),

r is the decay rate (expressed as a decimal).

In this case,

The initial amount A(0) is 500 grams, and the decay rate r is 4.5% per hour, which can be expressed as 0.045 (decimal form).

Thus,

The function to model the amount remaining after t hours is:

[tex]A(t) = 500 \times e^{-0.045t}[/tex]
