B) which of the letters A to K lie in the region where
(i) x >=2. y>=mx +n. and y>=px+q
(ii) y<=2. y<=mx+n. And y<=px+q
C)what is the maximum value of x+y in the region G
Answers
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.
An angle measures 66.4º more than the measure of its complementary angle. What is the
measure of each angle?
o and
o
Answers
Answer:
11.8° and 78.2°
Step-by-step explanation:
let the angles be x and x + 66.4
complementary angles sum to 90° , then
x + x + 66.4 = 90
2x + 66.4 = 90 ( subtract 66.4 from both sides )
2x = 23.6 ( divide both sides by 2 )
x = 11.8 and
x + 66.4 = 11.8 + 66.4 = 78.2
The 2 angles are 11.8° and 78.2°
1. The ratio (10^2000+10^2002) : (10^2001+10^2001)is closest to which whole number?
Answers
Answer:
5
Step-by-step explanation:
The whole number obtained as the result of the ratio (10²⁰⁰⁰⁰+10²⁰⁰²) : (10²⁰⁰¹+10²⁰⁰¹) is 5.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers. Comparing two numbers by dividing them is how ratios work. Your formula would be A/B if you were contrasting one data point (A) with another data point (B).
It is given that the ratio is,
(10²⁰⁰⁰⁰+10²⁰⁰²) : (10²⁰⁰¹+10²⁰⁰¹)
We have to apply the arithmetic operation for the given ratio in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
[tex]=\frac{10^{2000}+10^{2002}}{10^{2001}+10^{2001}} \\\\ =\frac{10^{2000}(1+100)}{10^{2000}(10+10)} \\\\ =\frac{101}{20} \\\\=5[/tex]
Thus, the whole number obtained as the result of the ratio (10²⁰⁰⁰⁰+10²⁰⁰²) : (10²⁰⁰¹+10²⁰⁰¹) is 5.

Step-by-step explanation:
The absolute value parent function, f(x) = | x |, is defined as:
[tex]f(x)=\begin{cases}x \; &\text{if}\;x > 0\\0 \; &\text{if} \; x=0\\-x\; &\text{if}\;x < 0\end{cases}[/tex]
Therefore:
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]
Part (d)Given absolute value expression:
[tex]|(x-19)+11|[/tex]
Simplify the given expression:
[tex]|(x-19)+11|=|x-19+11|=|x-8|[/tex]
Set the simplified absolute value expression to zero and solve for x:
[tex]\begin{aligned}\implies |x-8|&=0\\x-8&=0\\x&=8\end{aligned}[/tex]
Therefore, the vertex of the graph of the given absolute expression is (-8, 0).
Therefore, the slope of the expression will be positive for values of x greater than 8, and negative for values of x less than 8. 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 +(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]
Part (e)Given absolute value expression:
[tex]|14-(x-6)|[/tex]
Simplify the given expression:
[tex]|14-(x-6)|=|14-x+6|=|20-x|[/tex]
Set the simplified absolute value expression to zero and solve for x:
[tex]\begin{aligned}\implies |20-x|&=0\\20-x&=0\\x&=20\end{aligned}[/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:
[tex]\textsf{Positive slope}: \quad -(20-x) =-20+x=x-20[/tex][tex]\textsf{Negative slope}: \quad +(20-x) =20-x[/tex][tex]|14-(x-6)|=\begin{cases}x-20 \; &\text{if}\;x > 20\\0 \; &\text{if} \; x=20\\20-x \; &\text{if}\;x < 20\end{cases}[/tex]

Set the simplified absolute value expression to zero and solve for x:
[tex]\begin{aligned}\implies |x+8|&=0\\x+8&=0\\x&=-8\end{aligned}[/tex]

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.

Point P′(5, −4) is the image of point P(2, 3) under a translation. What is the image of (6, −2) under the same translation?
Answers
Answer:

Step-by-step explanation:
P (2, 3 ) → P' (5, - 4 )
2 → 5 in the x- direction is + 3
3 → - 4 in the y- direction is - 7
translation rule is then (x, y ) → (x + 3, y - 7 ) , so

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?
Answers
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.
