The front door is twice as long as the bedroom door.

A bedroom door in the house has the same dimensions and length and all at the front door. The length is 30 in rather than 63. If the bedroom door has a length of 30 inches, and the front door has the same dimensions but is longer, we can compare the two lengths using a proportion.

We can write the proportion as 30 inches / x inches = 1/2, where x is the length of the front door. To find the length of the front door, we can cross-multiply and solve for x: x = 30 inches * 2 = 60 inches. So the front door is 60 inches long, which is twice as long as the bedroom door.

Option 1 is Correct. For the line connecting the two locations, an equation in slope-intercept form is. y = x + 3

A line's slope and intercept give information on its steepness and the point at which it crosses an axis, respectively. The linear relationship between two variables is defined by the slope and intercept, which can be used to calculate the average rate of change.

When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilize the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.

The rank of object according to acceleration from greatest to least is:

C = B > A

In the given question, we have to rank the magnitude of each object's acceleration from greatest to least: Disregard the direction of the accelerations.

The acceleration is given by:

a = [tex]\frac{dv}{dt}[/tex]

where, dv represents change in velocity and dt represents change in time.

Also, Acceleration = slope of velocity - time graph

For object A acceleration is 0 because velocity is constant.

Now for object B:

[tex]a_{B}=\frac{5-0}{10-0}[/tex]

[tex]a_{B}=\frac{5}{10}[/tex]

[tex]a_{B}=\frac{1}{2}[/tex]

[tex]a_{B}[/tex] = 0.5 m/s square

Now for the object C:

[tex]a_{C}=\frac{-5-0}{10-0}[/tex]

[tex]a_{C}=-\frac{5}{10}[/tex]

[tex]a_{C}=-\frac{1}{2}[/tex]

[tex]a_{C}[/tex] = -0.5 m/s square

As we know that magnitude cannot be negative, so

[tex]a_{C}[/tex] = 0.5 m/s square

As we can see that acceleration of object B and C is same although the acceleration of object A is 0 which is smaller than the acceleration of B and C.

So the rank of object according to acceleration from greatest to least is:

C = B > A

The solution to the system of equations is x = −2, y = ±√23.

Equation is a math statement that expresses two expressions with an equal sign. It is used to find the value of an unknown variable or unknowns. Equations are used in many branches of mathematics and science. For example, equations are used to calculate the force of gravity, the speed of light, the temperature of a gas, and the area of a triangle. Equations are also used to solve problems in physics, chemistry, engineering, and other disciplines. Equations are written in symbols and often involve multiple equations.

This system can be solved by solving the two equations separately.

For the first equation, xe^y+2e^y= 0, we can rearrange it to get xe^y = −2e^y. We can then divide both sides by e^y to get x = −2.

For the second equation, x² − 3x + y² = 19, we can plug in the value of x that we found previously, x = −2, and rearrange the equation to get y² = 23, and then solve for y by taking the square root of both sides, giving y = ±√23.

Therefore, the solution to the system of equations is x = −2, y = ±√23.

The correlation coefficient, r, is a unitless measure and it is not affected by the units of measurement of the variables. Changing the units of measurement of one or both variables will not change the correlation coefficient.

If heart disease death rate were expressed as deaths per 1,000 people instead of as deaths per 100,000 people, the correlation r between wine consumption and heart disease death rate would not change. The strength and direction of the linear link between two variables is measured by the correlation coefficient, or r.

The correlation coefficient is calculated by taking the covariance of the two variables and dividing it by the product of the standard deviations of the two variables. The covariance is a measure of how two variables vary together, and it is not affected by the units of measurement.

The standard deviation is also not affected by the units of measurement, as it is a measure of how much the data deviates from the mean.

After calculating the average of his last 4 years’ salaries and will give him 1. 9% of that average for each year he worked, the total pension is $2928.204.

In the given question, we have to calculate Henry pension.

Henry has worked for a factor for 31 years and will be retiring.

He earned salaries over the past 4 years of $38433, $37776, $39125, and $38782.

His employer calculates pension by finding the average of his last 4 years’ salaries and will give him 1.9% of that average for each year he worked.

His earning over the past 4 years = $38433, $37776, $39125, $38782

The average of Henry earning = Sum of his earning over 4 years / number of years

The average of Henry earning = ($38433 + $37776 + $39125 + $38782)/4

The average of Henry earning = $154,116/4

The average of Henry earning = $38,529

Hence, the average of Henry last 4 years’ salaries is $38,529.

The pension is 1.9% of the average salary. So,

Pension = $38,529×1.9%

Pension = $38,529×0.019

Pension = $732.051

He worked for total 4 years. So,

Total pension = $732.051×4

Answer: d 135 ft

Step-by-step explanation:

This is a linear system since it is a linear combination of the inputs x[n] and x[n-1].

A: y[n] = x[n] x x[n-1]

This is a linear system since it is a linear combination of the inputs x[n] and x[n-1]. We can represent this equation as:

y[n] = a * x[n] + b * x[n-1]

where a and b are constants.

For example, if x[n] = 2 and x[n-1] = 3 then y[n] = 2 x 3 = 6.

C: y[n] = x2[n]

This is also a linear system since it is a linear combination of the input x[n] and its squared value x2[n]. We can represent this equation as:

y[n] = c * x[n] + d * x2[n]

where c and d are constants.

For example, if x[n] = 2 then y[n] = c * 2 + d * 2² = c * 2 + d * 4.

Step-by-step explanation:

replace both x and y in the equation with 3 and solve, you will get 3=3 so its true

Answer:

No

Step-by-step explanation:                                 x  y

First thing you have to do is plug y in for y. (3,3)

y= -2x+3

3= 2x+3

Then plug in x for x.

3 = -2(3) +3

Then solve the problem.

3= -6+3

3 = -3

From there we can tell that negative 3 is not the same as positive 3. Another thing you can do is go to desmos graphing calculator and type the equation in and see where the point (3,3) is located and notice that it does not go through the line from the equation.

The given expression is of the form y=mx+c. Comparing, we get the slope as 7.

The direction and steepness of a line are represented numerically by the slope or gradient of the line. It provides the ratio of how much y rises when x rises by a particular amount. The general form is therefore y=mx+c, where c represents the y-intercept and m represents the slope. This form gives the slope-intercept form.

Given the expression is  y=7x+3. Comparing this expression with the general form we get, slope or gradient as 7 and y-intercept as 3. Therefore, the required answer is 7.
