Answer:

the answer is 11.

Step-by-step explanation:

To find the number of integers divisible by 6 between -30 and 39, we need to find how many multiples of 6 are in this range.

The first multiple of 6 greater than -30 is -24 (which is 6 times -4), and the last multiple of 6 less than 39 is 36 (which is 6 times 6).

So, we need to count the number of integers between -4 and 6 (inclusive), because each of these integers multiplied by 6 will give us an integer in the range -30 to 39 that is divisible by 6.

There are a total of (6 - (-4) + 1) = 11 integers between -4 and 6 inclusive, so there are also 11 integers between -30 and 39 that are divisible by 6.

Answer:

1) x = 80

2) x = 95

3) x = -7

4) x= 32

5) No

Step-by-step explanation:

1) 180 - 60 - 40 = 80

2) 180 - 35 - 50 = 95

*Those two questions you use 180 (the total degrees of a triangle) to figure out the missing angle.*

3) 180 - 76 - 41 = 63

x + 70 = 63 (subtract 70 to get -7)

*You are trying to find x not the angle. So you need to find the angle (the first part) and plug in to find what x needs to be*

4) 180 - 122 = 58

*Those two angles are supplementary*

180 - 90 - 58 = 32

5) No because the three angles don’t add up to 180

85 + 45 + 45 = 175 Needs to be 180

After 2.10 years, there will be 8 grams of radioactive substance left.

The rate of decay of a radioactive substance is proportional to the amount of substance present.

Thus, we can conclude that the quantity of the radioactive substance present decreases exponentially over time.

A radioactive decay constant is defined as the fraction of the substance that decays in a unit of time, t.

According to the given statement, the rate of decay of a radioactive substance is proportional to the amount of substance present.

Suppose that the quantity of radioactive substance present initially is A0.

Then, the decay constant is represented by λ.

As the substance continues to decay, the remaining amount of the substance present after time t can be given by the exponential decay equation:  A(t) = A0e-λt

where A(t) represents the amount of substance present after time t.

In this problem, we are given that 12 grams of the substance were initially present, and now there are 8 grams. Therefore, we need to find out the value of t using the given data.

For this, we can use the exponential decay equation:  A(t) = A0e-λt

Let's assume that the amount of the substance present after time t is A(t) = 8 g, A0 = 12 g

Thus, the equation becomes 8 = 12e-λt

To find the value of λ, we can rearrange the equation and take the natural logarithm on both sides:

ln (8/12) = ln (e-λt)ln (8/12)

= -λt ln (e)ln (8/12)

= -λt λ = -ln (8/12)/t λ = ln (12/8)/t λ = 0.2877/t

Since we now know the value of λ, we can substitute the values of A0 and λ in the exponential decay equation to find the value of t.

A(t) = A0e-λtA(t) = 12e-0.2877/t

A(t) = 8 (Given)

Therefore, 8 = 12e-0.2877/t 0.6667 = e-0.2877/t

Taking natural logarithm on both sides, we get:

ln (0.6667) = ln (e-0.2877/t)ln (0.6667)

= -0.2877/t ln (e)ln (0.6667)

= -0.2877/t t

= -0.2877/ln (0.6667) t

= 2.10 years.

In the direct synthesis method for controller design, the process dynamics are described by the transfer function \(G_p = \frac{5}{(s+2)(s+3)}\).

The transfer function \(G_p\) represents the relationship between the input and output of the process. In this case, the transfer function is a ratio of polynomials in the Laplace domain, where \(s\) is the complex frequency variable.

To design the controller using the direct synthesis method, the transfer function of the desired closed-loop system, denoted as \(G_c\), needs to be specified. The controller transfer function is then determined by the equation \(G_c = \frac{1}{G_p}\).

In this scenario, the transfer function of the process is given as \(G_p = \frac{5}{(s+2)(s+3)}\). To find the controller transfer function, we take the reciprocal of \(G_p\), yielding \(G_c = \frac{1}{G_p} = \frac{(s+2)(s+3)}{5}\).

The resulting controller transfer function \(G_c\) can be used in the direct synthesis method for controller design, where it is combined with the process transfer function \(G_p\) to form the closed-loop system.

It's important to note that this summary provides an overview of the direct synthesis method and the transfer functions involved. In practice, further steps and considerations are needed for a complete controller design.

The exponential function f (x) = 2500 (0. 4)ˣ models the amount of money in Zachary's savings account over the last 10 year's. Zachary's amount balance is decreasing.

Exponential Function:

An exponential function is a mathematical function represented by f(x) = exp(x) or eˣ (where the argument x is written as an exponent). Unless otherwise specified, the term generally refers to positive-valued functions of real variables, although it can be extended to complex numbers or generalized to other mathematical objects such as matrices or Lie algebras. The exponential function originated from the idea of ​​exponentiation (repeated multiplication), but the modern definition (with several equivalent representations) allows it to be extended strictly to all real arguments, including irrational numbers.

According to the Question:

For an Exponential Function in the form y = a. bˣ

Because b=0.4, then,  Zachary's amount balance is decreasing.

Now,

Because the function is decreasing then it is exponential decay function and b is the decay factor.

And, In the exponential decay function

A(t) = a(1 -r)ᵇ , the decay factor is given by (1 - r) so:

Brett's claim that AABC is congruent or similar to ADEF is false

Congruence of Triangles: Two triangles are said to be congruent if all three corresponding sides are equal and all  three corresponding angles are equal.

From the given information, we can see that both AABC and ADEF are right triangles because they have one angle that is 90 degrees.  

However, we cannot conclude that AABC and ADEF are congruent (that is, identical in size and shape) because there is not enough information to determine their side lengths and the remaining angles.

Also, we  cannot conclude that AABC and ADEF are similar (ie have the same shape but possibly different sizes) because we only know one pair of corresponding angles (ie right angles) and one pair of corresponding sides (ie AC and DF), which  not enough to show similarity.  Therefore, Brett's claim that AABC is congruent or similar to ADEF is false, and we cannot conclude that AABC-ADEF (ie the difference between these two triangles) is a triangle with well-defined sides and angles.

Two lines that form a right angle at their point of intersection are perpendicular to each other.

The negative reciprocal is equal to the slope of the perpendicular lines. A transversal line is a line that is perpendicular to two parallel lines. Equal pairs of alternate angles and matching angles are created in the case of the transversal line.

When two lines intersect at a right angle, they are perpendicular to each other. The junction is referred to as the point of perpendicularity. The perpendicular lines form a 90-degree angle, and they can be used to create a coordinate system or used in geometric constructions. Such lines are called perpendicular lines.

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

23 kg is equivalent to 50.7098 pounds.

When converting between units of weight, it is important to understand the relationship between the units. Kilograms (kg) and pounds (lbs) are both units of weight, but they are not equivalent. One kilogram is equal to 2.20462 pounds.

To convert kilograms (kg) to pounds (lbs), you can use the conversion factor of 2.20462. The formula to convert kg to lbs is:

lbs = kg x 2.20462

So, to convert 23 kg to pounds, we can plug in the value of 23 for kg and multiply it by 2.20462:

lbs = 23 x 2.20462

lbs = 50.7098

Sagoff distinguished between efficiency and principle by arguing that efficiency is a subordinate value that should not be considered when making ethical decisions, whereas principle is a higher value that should always be taken into account when making ethical decisions.

According to Sagoff, efficiency is the value that underlies economics, but it should not be used as the sole criterion for making ethical decisions because it is subordinate to the value of principle. According to Sagoff, the value of a principle is higher value than the value of efficiency, and it is, therefore, more important than efficiency in making ethical decisions.

In general, Sagoff's argument is that the moral significance of a particular action or policy depends on its conformity to fundamental ethical principles such as respect for persons, justice, and beneficence, rather than on its economic efficiency.

Sagoff contends that we cannot adequately address the moral issues raised by environmental problems if we rely solely on economic efficiency and neglect the ethical principles that are at the heart of environmental ethics. Therefore, we need to take into account both efficiency and principle when making ethical decisions.

How to do graph representation?

Graph representation is a way of visualizing data as a graph or chart. It is used to easily identify relationships between data points and to illustrate trends in the data. Graphs can be used to present data in a variety of ways, such as bar graphs, line graphs, pie charts, scatter plots and more. Graphs are especially useful when trying to compare two or more sets of data and to highlight any patterns or trends that may exist. Additionally, graphs are often used to represent numerical data in a more visually appealing way. By using graphs, it is easier to identify relationships, trends and outliers in the data. Graphs also help to make data easier to interpret and understand.
