Moving the glass from one place to other is rigid transformation.

Step-by-step explanation:

The rigid transformation includes rotation, translation, reflection or their combination.

So, Moving the glass from one place to other place is translation. It is example of rigid transformation.

Now, cutting a piece of bread is not rotation or translation or reflection. So, it is NOT rigid transformation.

Squeezing the cherry is not rotation or translation or reflection. So, it is too NOT rigid transformation.

Answer:

the best answer is option d

Step-by-step explanation:

4/5 x -10 = -40/5 = -8

t x t = t^2

-8t^2

Answer:

\( \sf \: d) \: - 8 {t}^{2} \)

Step-by-step explanation:

Given expression,

\( \sf \rightarrow \: \frac{4}{5}t \: ( - 10t )\)

Let's simplify the expression,

\( \sf \rightarrow \: \frac{4}{5} t \: ( - 10t) \: \)

\( \sf \rightarrow \: ( \frac{4}{5} \times - 10)( {t} \times t)\)

\( \sf \rightarrow \: ( \frac{ - 40}{ \: 5} )( {t}^{2} )\)

\( \sf \rightarrow \: - 8{t}^{2} \)

Hence, the option (d) is correct.

The logistic differential equation for the hyena population is given by:

dP/dt = r * P * (1 - P/K)

where P(t) is the hyena population at time t, r is the growth rate, and K is the carrying capacity.

We are given that:

P(t) = 40 + k * e^(-0.57t)

K = 200

To determine the value of k, we can plug in these values into the logistic differential equation and solve for k:

dP/dt = r * P * (1 - P/K)

dP/dt = r * P * (1 - P/200)

dP/dt = r/200 * (200P - P^2)

dP/(200P - P^2) = r dt

Integrating both sides, we get:

-1/200 ln|200P - P^2| = rt + C

where C is a constant of integration.

Using the initial condition P(0) = 40 + k, we can solve for C:

-1/200 ln|200(40+k)-(40+k)^2| = 0 + C

C = -1/200 ln|8000-480k|

Plugging in this value of C and simplifying, we get:

-1/200 ln|200P - P^2| = rt - 1/200 ln|8000-480k|

ln|200P - P^2| = -200rt + ln|8000-480k|

|200P - P^2| = e^(-200rt) * |8000-480k|

200P - P^2 = ± e^(-200rt) * (8000-480k)

Since the population is increasing, we choose the positive sign:

200P - P^2 = e^(-200rt) * (8000-480k)

Using the initial condition P(0) = 40 + k, we get:

200(40+k) - (40+k)^2 = (8000-480k)

8000 + 160k - 2400 - 80k - k^2 = 8000 - 480k

k^2 + 560k - 2400 = 0

(k + 60)(k - 40) = 0

Thus, k = -60 or k = 40. Since k represents a growth rate, it should be positive, so we choose k = 40. Therefore, the value of the constant k is option (A) 4.

For the second part of the question, the logistic equation that could model the growth in the graph is option (B) dM/dt = (20-M)*(M-50). This is because the carrying capacity is between 20 and 50, and the population growth rate is zero at both of these values (i.e. the population does not increase or decrease when it is at the carrying capacity).

Answer:

-2.9

Step-by-step explanation:

-10x + 1 + 7 = 37

Combine like factors.

-10x + 8 = 37

Subtract 8 from both sides.

-10x = 29

Divide both sides by -10.

x = -2.9

Answer:

x = -29/10 = -2 9/10

Step-by-step explanation:

-10x + 1 + 7 = 37

Combine like terms

-10x +8 = 37

Subtract 8 from each side

-10x + 8-8 = 37-8

-10x = 29

Divide each side by -10

-10x/-10 = 29/-10

x = -29/10

x = -2 9/10

The solution to the equation is that there are infinite solutions to the simultaneous equation.

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y.

They are called simultaneous equations because the equations are solved at the same time.

2x - 4y = -6  --1

-x + 2y = 3   --2

From equation 2

-x + 2y = 3

x = 2y - 3

Substitute in equation 1

2(2y - 3) - 4y = -6

4y - 6 - 4y = -6

4y - 4y = -6 + 6

Answer: -30

Let's call the original number "x". Then, we can write the equation as follows:

-3/10 x + 1 = 10

To find the original number, we can isolate x by subtracting 1 from both sides and then multiplying both sides by 10/3:

-3/10 x = 9

x = (9 * 10)/(-3)

x = -30

So, the original number is -30.

The differential equation y - 2y⁶ = (y³ + 5x)y' can be written in differential form: M(x, y)dx + N(x, y)dy = 0, where M(x, y) = y³ + 5x and N(x, y) = y².

The term M(x, y)dx + N(x, y)dy becomes an exact differential if the left-hand side above is divided by y⁶. Integrating that new equation, the solution of the differential equation is y = C/(x³ + 5). To show that M(x, y)dx + N(x, y)dy is an exact differential, we need to show that ∫M(x, y)dx = ∫N(x, y)dy for some function F(x, y). In this case, we have:

∫M(x, y)dx = ∫(y³ + 5x)dx = x⁴ + 5x²

∫N(x, y)dy = ∫y²dy = y³/3

Therefore, F(x, y) = x⁴ + 5x² + y³/3. We can then write the differential equation as:

dF(x, y) = (y³ + 5x)y'/y⁶

Integrating both sides of this equation, we get:

F(x, y) = ∫(y³ + 5x)y'/y⁶ dy = y/(x³ + 5) + C

where C is an arbitrary constant. Therefore, the solution of the differential equation is y = C/(x³ + 5).

it is important to keep in mind that the results of a polygraph test should not be taken as absolute proof of deception or truthfulness, and that other factors should also be considered in evaluating a job applicant

While lie-detector tests (also known as polygraph tests) are sometimes used as part of a job application process, their reliability and accuracy are controversial and have been questioned by many experts in the field. The test measures physiological responses such as heart rate, blood pressure, and sweat gland activity in response to questions, and the results are interpreted by a trained examiner to determine whether the person is being truthful or deceptive.

However, there are several factors that can affect the results of a polygraph test, including the person's physiological state (such as anxiety or stress), the wording and interpretation of the questions, and the skills and biases of the examiner. False positives (indicating deception when the person is actually telling the truth) and false negatives (indicating truthfulness when the person is actually lying) are also possible.

In your case, it is possible that the lie-detector test gave a false positive result, indicating deception when you were actually telling the truth. There could be various reasons for this, such as anxiety or stress during the test, a misunderstanding or misinterpretation of the questions, or an error in the administration or interpretation of the test.

Step-by-step explanation:

Henry opens a savings account with an annual interest rate of 4.5 percent. After a year, he gets $75,000 in payment. He made a deposit into the savings account of $72,831.68.

Here are the steps on how to calculate the amount Henry invested:

Convert the annual interest rate to a monthly rate.

\(\begin{equation}4.5\% \div 12 = 0.375\%\end{equation}\)

Calculate the number of years.

\(\begin{equation}\frac{18 \text{ months}}{12 \text{ months/year}} = 1.5 \text{ years}\end{equation}\)

Use the compound interest formula to calculate the amount Henry invested.

\(\begin{equation}FV = PV * (1 + r)^t\end{equation}\)

where:

FV is the future value ($75,000)

PV is the present value (unknown)

r is the interest rate (0.375%)

t is the number of years (1.5 years)

\(\begin{equation}\$75,000 = PV \cdot (1 + 0.00375)^{1.5}\end{equation}\)

\$75,000 = PV * 1.0297

\(\begin{equation}PV = \frac{\$75,000}{1.0297}\end{equation}\)

PV = \$72,831.68

Therefore, Henry invested \$72,831.68 in the savings account.

The conditional PMF of Y=i given X=1 is 1 if i=1 and 0 otherwise and  X and Y are not independent because the value of X affects the possible range of values for Y.



a. To compute the conditional probability mass function (PMF) of Y=i given X=1, we need to find the probability of Y=i when X=1. Since X=1, the only possible outcome is (1,1), and Y can only be 1. Hence, the conditional PMF of Y=i given X=1 is:

P(Y=i | X=1) = 1, if i=1; 0, otherwise.

b. X and Y are not independent. If they were independent, the outcome of one die roll would not provide any information about the other die roll. However, given that X is the largest value and Y is the smallest value, we can see that X directly affects the possible range of values for Y. If X is 6, then Y cannot be greater than 6. Therefore, the values of X and Y are dependent on each other, and they are not independent.

A whole can be represented by any number, as well as by equivalent parts and fractions. In written English, fractions indicate how many units of a particular size there are. 8, 3/4. Fractions are pieces of a whole. In mathematics, numbers are stated as the ratio comparing the numerator to its denominator. They can all be expressed as simple fractions or integers. A fraction is present in the denominator or numerator of a complex fraction. True fractions have numerators that are less than their denominators. An amount that represents a fraction of a total is called a fraction. You can analyse anything by disassembling it into smaller parts. For instance, the number 12 represents half of a whole number or object.

given,

According to the information provided, Eve makes 6 baskets for every three that she misses. Accordingly, she makes 6 of her 9 attempts at the free throw line while missing 3. By multiplying the numerator as well as denominator of this fraction by three, we may simplify it to:

6/3 = 2/1

3/3 = 1/1

So, for every 2 + 1 = 3 free throws, she makes 2 and misses 1.

If Eve missed 36 free throws at her last practice, we can find out how many free throws she attempted by multiplying 36 by 3, which gives:

36 x 3 = 108

Therefore, Eve attempted 108 free throws in total. Since we know that for every 3 free throws, she makes 2 and misses 1, we can divide 108 by 3 to get the number of sets of 3 free throws she attempted:

108 / 3 = 36

This means that she attempted 36 sets of 3 free throws. For each set of 3, she made 2 free throws, so the total number of free throws she made is:

36 x 2 = 72

Therefore, Eve made 72 free throws at her last practice.
