Answer:
[tex](n - 3)^2 = 7[/tex]
Step-by-step explanation:
From the question, we understand that the number is n.
Three less than n is:
[tex]n - 3[/tex]
The square is:
[tex](n - 3)^2[/tex]
The square equals 7;
So, we have:
[tex](n - 3)^2 = 7[/tex]
Which shows the list of numbers in order from least to greatest?
|-4.2|, |-4/5|, |-1|, -2, |3.5|
Answer:
-4.2 (least) < -2 < -1 < -4/5 < 3.5 (greatest)
| | is called absolute value, but you can ignore it as |-4.2| equals to -4.2
The length of a side of a square is (2x + 9) km. Find the area of the square in terms of the variable x.
State if the two triangles are congruent. If they are, state how you know.
Explanation:
AAS = angle angle side
The arc markings show us which pairs of angles are congruent. The pair of congruent sides are the shared overlapping sides. Notice that the sides are not between the red angles, so we go for AAS instead of ASA. The order is important.
We cannot use SAS because we only know info about one pair of congruent sides (not two).

Why do people engage in various ?
Answer:
When and why do people engage in different forms of proactive behavior at work? We propose that as a result of a process of trait activation, employees with different types of self-construal engage in distinct forms of proactive behavior if they work in environments consistent with their self-construals. In an experimental Study 1 (n = 61), we examined the effect of self-construals on proactivity and found that people primed with interdependent self-construals engaged in more work unit–oriented proactive behavior when job interdependence was also manipulated. Priming independent self-construals did not enhance career-oriented proactive behavior, even when we manipulated job autonomy. In a field Study 2 (n = 205), we found that employees with interdependent self-construals working in jobs with high interdependence reported higher work unit commitment and higher work unit–oriented proactive behavior compared to employees in low interdependent jobs. Employees with independent self-construals working in jobs with high autonomy also exhibited stronger career commitment and more career-oriented proactive behavior than did those in jobs with low autonomy. This research offers a theoretical framework to explain how dispositional and situational factors interactively shape people’s engagement in different forms of proactive behavior.

There is a pair of parallel sides in the following shape.
2 12 13 7
What is the area of the shape?
___units
The area of the shape is the amount of space on the shape
Using the assumed parameters, the area of the shape is 25 square units
How to determine the area?The question is incomplete, as the shape is not given.
Assume the shape is a trapezoid, the area of the shape would be:
A = 0.5 * (sum of parallels sides) * height
Using the assumed values, we have:
Area = 0.5 * (12 + 13) * 2
Evaluate the product
Area = 25
Using the assumed values, the area of the shape is 25 square units

The kinetic energy k of an object in joules is given by the formula k=1/2mv² where m is the object's mass in kilograms and v is its velocity in meters per second. An object’s velocity is 20 meters per second, and its kinetic energy is 48,000 joules. If it speeds up to 40 meters per second, what is its new kinetic energy?
Answer:
192000 J
Step-by-step explanation:
k = 1/2 mv²
48000 = 1/2 x m x (20)²
48000 = 200m
m = 240 kg
new k
k = 1/2 x 240 x 40²
k = 192000 J

A train is traveling at a speed of 80 km/h when the conductor applies the brakes. The train slows with a constant acceleration of magnitude .5 m/s^2. We want to find the distance the train travels from the time the brakes are applied until the train comes to a complete stop. Which kinematic formula would be most useful to solve for the target unknown?
Answer:
The train will travel 493.817 meters until it stops completely.
Step-by-step explanation:
In this case, we know that train applies the brakes and decelerates at constant rate until rest is reached after travelling an unknown distance. Travelled distance ([tex]\Delta s[/tex]), measured in meters, can be found by using this kinematic formula:
[tex]v^{2} = v_{o}^{2}+2\cdot a \cdot \Delta s[/tex] (Eq. 1)
Where:
[tex]v_{o}[/tex] - Initial speed, measured in meters per second.
[tex]v[/tex] - Final speed, measured in meters per second.
[tex]a[/tex] - Acceleration, measured in meters per square second.
Now travelled distance is cleared within the formula:
[tex]\Delta s = \frac{v^{2}-v_{o}^{2}}{2\cdot a}[/tex]
If we know that [tex]v_{o} = 22.222\,\frac{m}{s}[/tex], [tex]v = 0\,\frac{m}{s}[/tex] and [tex]a = -0.5\,\frac{m}{s^{2}}[/tex], then the distance travelled by the train is:
[tex]\Delta s = \frac{\left(0\,\frac{m}{s} \right)^{2}-\left(22.222\,\frac{m}{s} \right)^{2}}{2\cdot \left(-0.5\,\frac{m}{s^{2}}\right) }[/tex]
[tex]\Delta s = 493.817\,m[/tex]
The train will travel 493.817 meters until it stops completely.

Let [tex]x[/tex] be the cost of 5 bags of bulk cereal.
3 is to $21.75 as 5 is to [tex]x[/tex], this translates to the following
[tex]\frac{3}{21.75}=\frac{5}{x}[/tex]

Find an equation of a line that is parallel to y = 3x - 9 and passes through
the point (1, 1). *
Answer:
y=3x-2
Step-by-step explanation:
For this problem, you can use the point-slope formula: y-y1=m(x-x1), with x1 and y1 being from the given coordinate, and m being the slope (which is 3 that can be seen in the equation). Since we're finding a line that is parallel to this line, the slopes of both equations are the same.
y-(1)=3(x-1)
y-1=3x-3
y=3x-2
Check:
(1)=3(1)-2
1=3-2
1=1
[tex]y=3x-2[/tex] is an equation of a line that is parallel to [tex]y = 3x - 9[/tex] and passes through the point [tex](1, 1).[/tex]
What is equation?
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
What is Parallel lines?
In geometry, parallel lines are coplanar straight lines that do not intersect at any point. Parallel planes are planes in the same three-dimensional space that never meet.
According to question, we have to write an equation of a line that is parallel to [tex]y = 3x - 9[/tex] and passes through the point [tex](1, 1)[/tex]
Since, the line passes through [tex](1,1)[/tex] and have slope[tex]=3[/tex]
So, [tex]y-(1)=3(x-1)[/tex]
⇒ [tex]y-1=3x-3[/tex]
⇒ [tex]y=3x-2[/tex]
Hence, we can conclude that [tex]y=3x-2[/tex] is an equation of a line that is parallel to [tex]y = 3x - 9[/tex] and passes through the point [tex](1, 1).[/tex]

Answer:
[0,9]
Step-by-step explanation:
The domain is the first set of the ordered pair. When finding the domain you are supposed to find which x value it starts from to where it ends. The x value starts from 0 and ends and the 9th unit on the x-axis which would give us 0,9 now since both points are closed you would use these symbols [ ] to show that it is closed meaning the answer would be [0,9]
