Step-by-step explanation:

formula:

(x-h)²+(y-k)²=r²             (h,k) is the center, you will have to calculate the r

r=\(\sqrt{(3-(-3))^{2} +(1-4)^{2} }\)

=\(\sqrt{36+9}\)

=\(\sqrt{45}\)             keep this as a square root, you will square it anyway

(x-3)² + (y-1)² = \((\sqrt{45} )^{2}\)

(x-3)² + (y-1)² = 45

The exponential function that shows the relationship between the city's population y and the number of years t since the start of the study is \(y = 390000 * (1.073)^t\)

Population tends to change with time. It might increase or decrease. Let y be the city's population after t years since the start of the study, and let \(Po\) be the initial population at the start of the study. We can use the formula for exponential growth to represent the relationship between y and t:

Final population = Initial population x (growth rate)^years

\(y = Po*(1+0.073)^t\)

\(y = Po* (1.073)^{(t)\)

Substituting the values in the above equation we get the following equation:

\(y = 390,000*(1.073)^t\)

The above function when represented in exponential form will be equal to \(y=390,000*(e)^{(0.073t)\)

False. If two lines are perpendicular, they do not have the same slope. When two lines are perpendicular, they intersect at a right angle, and their slopes are negative reciprocals of each other.

This implies that when one slope is a, the other slope is -1/a. We can define perpendicular lines using the following theorem.

The two lines in a plane are perpendicular if and only if the product of their slopes is -1. If line 1 has slope m1 and line 2 has slope m2, then the product of their slopes is m1*m2 = -1, which means m2 = -1/m1 and vice versa. The converse is also true, which means if m1*m2 = -1, then line 1 and line 2 are perpendicular.

Hence, the statement, "If two lines are perpendicular, they have the same slope" is false because the slopes of perpendicular lines are negative reciprocals of each other, not equal. Therefore, the answer is False.

Answer:

y = 0

Step-by-step explanation:

-2y-4=4(y-1)

First you want to distribute it

-2y - 4 = 4y - 4

Then just subtract -4y from both sides to neutralize 4y

-6y -4 = -4

then you have to add 4 to neutralize -4

-6y= 0

thus the answer is y= 0

Answer:

The P-value you would use to test the claim that the population mean of  pencils produced in that factory have a mean length equal to 18.0 cm is 0.00736.

Step-by-step explanation:

We are given that a quality control specialist at a pencil manufacturer pulls a random sample of 45 pencils from the assembly line.

The pencils have a mean length of  17.9 cm. Given that the population standard deviation is 0.25 cm.

Let \(\mu\) = population mean length of  pencils produced in that factory.

So, Null Hypothesis, \(H_0\) : \(\mu\) = 18.0 cm     {means that the population mean of  pencils produced in that factory have a mean length equal to 18.0 cm}

Alternate Hypothesis, \(H_A\) : \(\mu\neq\) 18.0 cm     {means that the population mean of  pencils produced in that factory have a mean length different from 18.0 cm}

The test statistics that will be used here is One-sample z-test statistics because we know about the population standard deviation;

                           T.S.  =  \(\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }\)  ~ N(0,1)

where, \(\bar X\) = sample mean length of pencils = 17.9 cm

           \(\sigma\) = population standard deviation = 0.25 cm

           n = sample of pencils = 45

So, the test statistics =  \(\frac{17.9-18.0}{\frac{0.25}{\sqrt{45} } }\)  

                                    =  -2.68

The value of z-test statistics is -2.68.

Now, the P-value of the test statistics is given by;

         P-value = P(Z < -2.68) = 1 - P(Z \(\leq\) 2.68)

                      = 1- 0.99632 = 0.00368

For the two-tailed test, the P-value is calculated as = 2 \(\times\) 0.00368 = 0.00736.

La probabilidad de que no haya demoras en un viaje de ida y vuelta es 0.64 (64%).

La probabilidad de que no haya demoras en un viaje de ida y vuelta se puede calcular utilizando la probabilidad complementaria. Si la probabilidad de que un vuelo se retrase es 0.2 (20%), entonces la probabilidad de que no haya retrasos en un vuelo individual es 1 - 0.2 = 0.8 (80%).

Para un viaje de ida y vuelta, la probabilidad de que no haya retrasos en ambos vuelos se calcula multiplicando las probabilidades de no retraso de cada vuelo.

Entonces, la probabilidad de que no haya demoras en un viaje de ida y vuelta sería 0.8 * 0.8 = 0.64 (64%), o 64 de cada 100 viajes de ida y vuelta no experimentarían retrasos.

Answer:

c. 4^3 * 5^2 (1600)

d. 9^4 * 7^2 (321489)

Step-by-step explanation:

Hi!

Remember that exponents are the number times itself (2*2 = 2^2).

So, in c, we have 4 times 4 times 4. We have 4 multiplied by 4 3 times. We can also write this as 4^3.

We also have 5 times 5. We can also write this as 5^2.

However, we need to multiply 5^2 by 4^3. So:

4^3 times 5^2 or 1600.

The solution to the system of equations that are represented by the table given is: (-1, 6).

Recall:

Solution to a system of equations that is represented by a table is the value of x that will give the same value of y for each linear equation.

Thus, from the table given, when x = -1, the values of y1 and y2 equals 6. This represents the solution of the system of equations.

(a) The differential equation is not in exact form.

(b) The integrating factor for the given differential equation is μ(t) = e^(-t).

(c)  The solution is  y = -e^(2t) + Ce^t, where C is a constant of integration.

(a) A differential equation is said to be in exact form if it can be written as M(x, y) dx + N(x, y) dy = 0, where the partial derivatives of M and N with respect to y and x, respectively, are equal, i.e., ∂M/∂y = ∂N/∂x. In the given differential equation, t dy/dt + (1 – t)y = e^2t, the partial derivatives of (1 – t)y with respect to y and t are -t and (1 - t), respectively, which are not equal. Therefore, the given differential equation is not in exact form.

(b) To transform the given differential equation into an exact form, we can find an integrating factor, denoted by μ(t), which is a function of t only. The integrating factor is obtained by dividing an expression involving the partial derivatives of the given equation with respect to y and t. In this case, we have ∂M/∂y - ∂N/∂x = -t - (1 - t) = -1. Thus, the integrating factor is μ(t) = e^(-∫1 dt) = e^(-t).

(c) Multiplying the given differential equation by the integrating factor e^(-t), we obtain e^(-t)(t dy/dt + (1 – t)y) = e^(-t)e^(2t). Simplifying this equation, we have e^(-t) d(ty) = e^(t). Integrating both sides with respect to t, we get ∫e^(-t) d(ty) = ∫e^(t) dt. The left-hand side can be evaluated as -e^(-t)y + C_1, where C_1 is the constant of integration. The right-hand side evaluates to e^t + C_2, where C_2 is another constant of integration. Combining these results, we have -e^(-t)y + C_1 = e^t + C_2. Rearranging the equation, we obtain y = -e^(2t) + Ce^t, where C = C_1 - C_2 is a constant of integration. This is the solution to the given differential equation.

In summary, the given differential equation is not in exact form. By finding an integrating factor of μ(t) = e^(-t), we transform the equation into an exact form. The solution to the transformed equation is y = -e^(2t) + Ce^t, where C is a constant of integration.

The decimal value of 'z' after running the given code is 220.

The code initializes a short integer 'x' with the value -36, which is represented in binary as 11011100. Since the machine uses 1 byte for a short integer, 'x' is stored using 1 byte.

Then, 'x' is assigned to an integer 'y'. Since 'y' is an int, it uses 2 bytes to store the value. However, the binary representation of -36 (11011100) can be accommodated within the 2 bytes.

Finally, 'y' is cast to an unsigned int 'z'. The cast discards the sign bit, converting the value to its unsigned representation. Since 'z' is unsigned, it also uses 2 bytes to store the value. Therefore, the binary representation of -36 (11011100) is interpreted as a positive value, resulting in the decimal value 220.

In summary, the decimal value of 'z' is 220 because the negative value -36 is represented in binary as 11011100, which is interpreted as a positive value when cast to an unsigned int.

Step-by-step explanation:

first, find the area of the triangle

formula: 1/2 (base × height)

so the area of the triangle is

= 1/2 (16×5)

= 1/2 (80)

= 40

then, find the area of the rectangle

formula: length × breadth

the area of the rectangle is

= 15 × 16

= 240

the area of the composite figure is the sum of the areas of the triangle and rectangle

= 40 + 240

= 280
