The value of [tex]k = 2P/x^2[/tex]
We are aware that an object's location might cause it to store energy. When a bow and arrow are used, the energy that is stored when the bow is pulled is what gives the arrow its kinetic energy when it is released.
when a spring is moved away from its equilibrium position, it gains some energy, which we can notice by the tension our hands experience as we stretch it. Potential energy is a type of energy that arises from a change in its position or condition, according to our definition
We know that P=1/2kx^2
Now solving for k
2P = kx^2
Therefore
k = 2P/x^2
Hence the value of k is 2P/kx^2

Evaluate each expression for the given values of the variables: 4|a|+8-a, if a =-2
The value of expression is 18.
modulus of functionA modulus function is a function that determines a number or variable's absolute value. A function with absolute values is another name for it. This function's result is always positive. let's suppose if you want to find modulus of -2 then you will get 2 as the answer.
now according to question
4|a|+8-a at a=-2
here a is negative that means modulus will give us positive value.
put a =-2 in the expression and get the answer. modulus of -2 will give us +2
so
=4(2)+8-(-2)
=8+8-(-2)
=8+8+2
=18

y = 4x² + 8x - 124 cancels throughout.
y = x² + 2x - 4Solving by quadratic formula :
x = -8 ± √(8)² - 4(4)(-12) / 8x = -8 ± √64 + 192 / 8x = -8 ± √256 / 8x = -8 ± 16 / 8x = -1 ± 2x = 1 and x = -3∴ Hence, the x-intercepts are (1, 0) and (-3, 0). The roots of the equation are 1 and -3.

For finding the given literal equation is necessary to apply the power 2 on both sides of the given equation and after that you should rewrite the equation as a function of the variable m .
Power RulesThere are different power rules, see some them:
1. Multiplication with the same base: you should repeat the base and add the exponents.
2. Division with the same base: you should repeat the base and subctract the exponents.
3.Power. For this rule, you should repeat the base and multiply the exponents.
4. Zero Exponent. When you have an exponent equals to zero, the result must be 1.

If 5/6 is 180, what is 1/6?
(please explain as well)
Answer: 36
Step-by-step explanation:
If 5/6 = 180
lets find what 1/6 equals
To do this lets divide 180 by 5 to find 1/6
[tex]\frac{180}{5} =36[/tex]
Therefore, 1/6 = 36
We know 180/5 will give us the answer because 180 is already 5/6 of the total; dividing by 5 will give us 1/6 of the total. Ex: if we had 4/6 of the total, we would divide by 4 to find 1/6.
Anyways, we can check our answer by doing:
36*5 = 216 then taking 5/6 of 216, which should equal 180
[tex]216*\frac{5}{6} =180[/tex]
Therefore, we know 36 is the correct answer
A rectangle's area is given by the expression 6–² -- − n +9. The width of the rectangle is 3n². w = 3n² A = 6n² − n +9
The length of the rectangle = 2 - (1/3n) +(3/n²).
How to estimate the length of a rectangle?
The formula for the area (taking this exists as a rectangle)
Area = length ⋅ width
where A exists the area of the rectangle
l exists the length of the rectangle and w exists the width of the rectangle.
If Area of the rectangle = length ⋅ width
then length of the rectangle = area/ width
Area = 6n² − n +9
width = 3n²
Area = length [tex]*[/tex] width
length = area/ width
= (6n² − n +9)/3n²
= 2 - (1/3n) +(3/n²).
The length of the rectangle = 2 - (1/3n) +(3/n²).
Therefore, the correct answer is option A. 2 - (1/3n) +(3/n²).

in a school, the ratio of the number of boys to the number of girls is 2:3 and the ratio of the number of girls to the number of teachers is 7:3. what is the ratio of the number of students to the number of teachers
Answer:
35:9
Step-by-step explanation:
The ratios can be combined by making the common element be represented by the same number.
Adjusted ratiosThe common element in the two ratios is the number of girls. In the first ratio, girls are represented by 3 ratio units. In the second ratio, they are represented by 7 ratio units. Multiplying the first ratio by 7 and the second ratio by 3 will make the number of girls the same in both.
boys : girls = 2 : 3 = 14 : 21
girls : teachers = 7 : 3 = 21 : 9
Then the extended ratio can be written ...
boys : girls : teachers = 14 : 21 : 9
The number of students is the total of the numbers of boys and girls, so we have ...
students : teachers = (14 +21) : 9
students : teachers = 35 : 9
Elimination was used to solve a system of equations.
One of the intermediate steps led to the equation 9x = 27.
Which of the following systems could have led to this equation?
O
9x + 2y = 21
-9x - 2y = 21
10x - y = 15
x+y = - 12
7x - 2y = 15
x + y = 6
4x + 3y = 24
-5x - 3y = 3
The system of equation that could have led to the equation 9x = 27 is
7x - 2y = 15
x + y = 6
The correct option is the third option
7x - 2y = 15
x + y = 6
Solving systems of equationsFrom the question, we are to determine the system that could have led to 9x = 27
1.
9x + 2y = 21
-9x - 2y = 21
Subtracting, we get
9x + 2y = 21
-9x - 2y = 21
-------------------
18x + 4y = 0
2.
10x - y = 15
x + y = - 12
Subtracting, we get
10x - y = 15
x + y = - 12
---------------------
9x -2y = 27
3.
7x - 2y = 15
x + y = 6
Here, multiply the second equation by 2
2 × [x + y = 6]
2x + 2y = 12
Now, add to the first equation
7x - 2y = 15
2x + 2y = 12
------------------
9x = 27
4.
4x + 3y = 24
-5x - 3y = 3
Subtracting, we get
4x + 3y = 24
-5x - 3y = 3
---------------------
9x + 6y = 21
Hence, the system of equation that could have led to the equation 9x = 27 is
7x - 2y = 15
x + y = 6
The correct option is the third option
7x - 2y = 15
