Answer: 2√10
Step-by-step explanation:
A way we can find what x equals, is to find the opposite of what ever sign is on a side, in the equation x^2=40, the opposite of squaring is to find the square root of it.
It is important that what you do to one side, you do to the other.
So we have to square root both sides so we can get rid of the ^2 on x to get x =. This would look like √x^2 = √40
The square root of x^2 would revert back to just x
To find the square root of 40, its important to first see if its a perfect square. In this scenario, it isnt. Because it isnt, we have to find the closest perfect square that we can multiply to get 40, in this equation, the closest would be 4 so we do 4*10.
Then we reduce the 4 by square root and we get 2
Then we cant do anything else with the 10, so we would right the answer as a radical, with the square root you got from the perfect square on the outside and the remainder on the inside of the square root, like x√r where x is the number obtained from square root and r is the remainder that we cant do anything else with.
After doing this, we get the answer 2√10, which can be said "two radical ten"
If m Greater-than-or-equal-to n, which inequalities must be true? Check all that apply. M 2. 1 Greater-than-or-equal-to n 2. 1 m - (-4) Greater-than-or-equal-to n -(-4) m - 3 Greater-than-or-equal-to n 3 16. 5 m Greater-than-or-equal-to 16. 5 n m Greater-than-or-equal-to n One-half 6 m Greater-than-or-equal-to 9 n.
The inequalities that must be true if m is greater-than-or-equal-to n are given as:
Option 1: [tex]m \times 2.1 \geq n \times 2.1[/tex]Option 2: [tex]m - (-4) \geq n - (-4)[/tex]Option 4: [tex]16.5m \geq 16.5n[/tex]What operations are allowed in inequalities?Only those operations are allowed which are sure to not modify the inequality between the expressions in the statement.
Some operations that are sure not to modify the inequalities are:
Addition, Subtraction, multiplication by positive real numbers, division by positive real numbers etc.
Example, if 5 > 2, then you can do whatever which keeps the term on the side of 5 bigger than the terms formed on side of 2.
Thus, 5 + 1 > 2 + 1 is correct, (it was addition of 1, a real number).
For the considered case, we're given that:
[tex]m \geq n[/tex]
Checking all the options sequentially, we get:
Case 1: [tex]m \times 2.1 \geq n \times 2.1[/tex]It must be true, since the multiplication is done by 2.1, which is > 0
Case 2: [tex]m - (-4) \geq n - (-4)[/tex]It must be true since -4 is a real number, and addition or subtraction of any real number (if done on all the sides of the statement) doesn't change the inequality
Case 3: [tex]m - 3 \geq n + 3[/tex]From [tex]m \geq n[/tex], addition or subtraction is guaranteed to not change the inequality only if they are of same quantity on all the sides of the inequality. Thus, this inequality is not necessary to be true.
Example, if we take m = 5, n =3, then,
[tex]5 \geq 3[/tex] but [tex]5 - 3=0 \: \rm and \: 3 + 3= 6 \implies 5-3 < 3 + 3[/tex]
Case 4: [tex]16.5m \geq 16.5n[/tex]It must be true if given that [tex]m \geq n[/tex] since multiplication of equal positive real number on both the sides of [tex]m \geq n[/tex] was done.
Case 5: [tex]\dfrac{1}{2} 6m \geq 9m[/tex]one-half of 6 = 3, thus, this inequality means [tex]3m \geq 9m[/tex]
Dividing both the sides by 3, we get:
[tex]m \geq 3n[/tex]
It is not necessary to be true if [tex]m \geq n[/tex]. Example
[tex]3 \geq 2\\but\\ 3 < 3 \times 2 = 6[/tex]
Thus, the inequalities that must be true if m is greater-than-or-equal-to n are given as:
Option 1: [tex]m \times 2.1 \geq n \times 2.1[/tex]Option 2: [tex]m - (-4) \geq n - (-4)[/tex]Option 4: [tex]16.5m \geq 16.5n[/tex]Learn more about inequality here:

If you have exponents in your answer use ^ for example:
2^3 = two to the power of three
Answer:
5x^2 - 8x - 32
Step-by-step explanation:
Area of rectangle = base x height
Area of larger rectangle = (3x - 8)(2x + 4)
= 6x^2 - 4x - 32
Area of smaller rectangle = (x + 4)x
= x^2 + 4x
Area of shaded region = area of larger rectangle - area of smaller rectangle
= (6x^2 - 4x - 32) - (x^2 + 4x)
= 5x^2 - 8x - 32

you get x^0 which is equal to 1 due to another rule of exponents
youll do 16-4 next and get 12 so y^12

SCALE DRAWING: An architect made this drawing to represent a
swimming pool. The actual length of the pool is 15 ft. What is the
actual width of the pool shown in the model.
O 20 Feet
O 12 Feet
O 60 Feet
O 15 Feet
Answer:
12ft.
If the real length was 15 but is 5 down in the drawing that means the scale is 3ft to every inch. (15/5 =3).
With that said the width of the drawing is 4 inches. 4 x 3 = 12..
The width of the real pool would be 12 ft.
Solve for n n/3 - 2 = 2
n/3-2 = 2
n/3 = 4
n = 12
The solution to the algebraic equation, n/3 - 2 = 2, is: n = 12.
How to Solve an Algebraic Equation?If given an algebraic equation, such as n/3 - 2 = 2, to solve for n, you have to isolate n as shown below:
n/3 - 2 = 2
Add 4 to both sides of the equation
n/3 = 2 + 2
n/3 = 4

Answer:
k = 30; y = 30/xy = 9; y = 36/xx = 5/2; k = 50y = 2; k = 24Step-by-step explanation:
When we say "y varies inversely as x", we mean that y is proportional to the inverse of x: y = k·(1/x). This relation is usually written ...
y = k/x
It can be solved for the other values:
xy = k . . . . multiply by x
x = k/y . . . divide by y
If you are given the equation, the value of k can be read directly from it: it is the constant in the numerator.
__
a)k = xy = 5·6 = 30; the equation is y = 30/x
b)y = k/x = 36/4 = 9; the equation is y = 36/x
c)k = 50 (read from the equation); x = k/y = 50/20 = 5/2
d)k = 24 (read from the equation); y = k/x = 24/12 = 2

The slope of the line where x > 0 is positive.The slope of the line where x < 0 is negative.Its graph is V-shaped and has the following properties:
The x-intercept and y-intercept are at the origin (0, 0).The vertex is at the origin (0, 0).The axis of symmetry is x = 0 (y-axis).The domain is the set of all real numbers: (-∞, ∞).The range is the set of all real numbers greater than or equal to 0: [0, ∞).Part (c)Given absolute value expression:
[tex]|3x+12|[/tex]
Simplify the given expression:
[tex]\implies |3x+12|=|3(x+4)|=3|x+4|[/tex]
Set the simplified absolute value expression to zero and solve for x:
[tex]\begin{aligned}\implies 3|x+4|&=0\\|x+4|&=0\\x+4&=0\\x&=-4\end{aligned}[/tex]
Therefore, the vertex of the graph of the given absolute expression is (-4, 0).
Therefore, the slope of the expression will be positive for values of x greater than -4, and negative for values of x less than -4. Set the expression inside the absolute value sign to positive and negative to find the two expressions with positive and negative slopes:
[tex]\textsf{Positive slope}: \quad +(3x+12) =3x+12[/tex][tex]\textsf{Negative slope}: \quad -(3x+12) =-3x-12[/tex][tex]|3x+12|=\begin{cases}3x+12 \; &\text{if}\;x > -4\\0 \; &\text{if} \; x=-4\\-3x-12\; &\text{if}\;x < -4\end{cases}[/tex]

[tex]\textsf{Positive slope}: \quad +(x-8) =x-8[/tex][tex]\textsf{Negative slope}: \quad -(x-8) =-x+8=8-x[/tex][tex]|(x-19)+11|=\begin{cases}x-8\; &\text{if}\;x > 8\\0 \; &\text{if} \; x=8\\8-x \; &\text{if}\;x < 8\end{cases}[/tex]

Therefore, the vertex of the graph of the given absolute expression is (20, 0).
Therefore, the slope of expression will be positive for values of x greater than 20, and negative for values of x less than 20. Set the expression inside the absolute value sign to negative and positive to find the two expressions with positive and negative slopes:

Answer:
A) x = 2; y = 2; (m, n) = (1/2, 0); (p, q) = (-3/2, 12)
B) K; A and E
C) 11
Step-by-step explanation:
With the exception of the vertical line, the equations of the lines can be written in terms of their slope and y-intercept. The slope is the ratio of "rise" to "run". The "rise" is the vertical change between points, and the "run" is the horizontal change between the same points. Changes to the right or up are taken as positive. The change amounts can be read from the graph by counting grid squares, or by subtracting coordinate values.
The regions described by an inequality will be to the right of a boundary line for x > (boundary), and above the boundary line for y > (boundary). When these inequalities are reversed, the region will be left or below the boundary, respectively.
__
A)The slope-intercept equation for a line is ...
y = mx +b . . . . where m is the slope, and b is the y-intercept
(i) x = 2 . . . . . . points on the vertical line have an x-value of 2
(ii) y = 2 . . . . . 0 slope, y-intercept of 2
(iii) m = 1/2, n = 0 . . . . rise = 1 for run = 2; y-intercept = 0
(iv) p = -3/2, q = 12 . . . . rise = -3 for run = 2; y-intercept = 12
__
B)(i) Region K is to the right of the vertical line, and above the two slanted lines
(ii) Regions A and E are below y=2 and the two slanted lines
__
C)The maximum value of x+y will be found at the point on the line x+y=c, where c is the largest possible value. That is, it will lie on the line ...
y = -x +c . . . . a line with a slope of -1
such that the line is as far as possible from the origin.
For region G, the point that maximizes "c" in the above equation is point (2, 9), so ...
c = x +y = 2 +9 = 11
The maximum value of (x+y) in region G is 11.
Write an equation to solve for x.

3. A rock is thrown from the top of a tall
building. The distance, in feet, between the
rock and the ground t seconds after it is
thrown is given by
d(t) =
4t + 382.
- 16t²
a. How long after the rock is thrown is it
370 feet from the ground?
b. After how many seconds will the rock
reach the ground?
c. What is the height of the rock when it
is halfway to the ground?
Answer:
Step-by-step explanation:
d(t) = 4t + 382 - 16t²
where d is the distance (in feet) between the rock and ground t seconds after thrown. Ground is 0 feet. As a note, I'm not clear why the "4t" term is in this equation. It has the effect of adding an increase in height at the rate of 4 feet/sec. I'll assume this is to accommodate any increase in height due to the throw, but it is a bit curious.
a. How long after the rock is thrown is it 370 feet from the ground?
The 382 in the equation represents the starting height of the rock (382 feet). To find the time to reach 370 feet:
370 = 4t + 382 - 16t²
Solve using the quadratic equation. There will be two answers, one negative, which we'll discard until we can go backwards in time. The positive value is 1, which would mean the rock will be at 370 feet in 1 second after throwing.
b. After how many seconds will the rock reach the ground?
Ground is 0 feet:
0 = 4t + 382 - 16t²
t = 5 seconds
c. What is the height of the rock when it is halfway to the ground?
The initial height is 382 feet, as per the equation, since when t = o (initial), d(t) is 382 feet. Halfway to the ground would be (382/2) or 191 feet.
