Let x = 0.147 and let y = 0.147.
Answer:
X is a rational number, y is not a rational number, and y is larger.
Step-by-step explanation:
The line above the 0.147 means that the number goes on forever and never stops. This is a characteristic of an irrational number. Rational numbers, however, do stop, so x is rational. Because y goes on forever, it has more values after the 0.147, making it larger.

The probability for event A is 0.4, the probability for event B is 0.2, and the probability of events A and B is 0.1.
Why are the events not independent?
The sum of P(A) and P(B) is greater than P(A and B).
The product of P(A) and P(B) is greater than P(A and B).
The product of P(A) and P(B) is not equal to P(A and B).
The sum of P(A) and P(B) is not equal to P(A and B).
kite EFGH is graphed on the coordinate plane. three of its verticies are E(1,6), F(3,5), and G(4,-3). what are the coordinates of the fourth vertex, H?
The coordinates of the fourth vertex, H is; (-6.056, 7.302)
How to find the Coordinates of a Kite?
A kite has 4 sides and we know that a pair of diagonally opposite angles of a kite are said to be congruent.
We are given the coordinates of its' vertices as;
E(1,6), F(3,5), and G(4,-3).
The two diagonals are perpendicular;
Slope of EG = (-3 - 6)/(4 - 1)
Slope of EG = -9/5
Equation of line passing through G is;
y = mx + c
-3 = -9/5(4) + c
-15 = -36 + 15c
c = 51/15 = 17/5
y = (-9/5)x + 17/5 ------(1)
Equation of line passing through F is;
y = mx + c
6 = (5/9)(1) + c
54 = -9 + 9c
c = 7
y = (5/9)x + 7 -----(2)
Solving eq 1 and eq 2 simultaneously gives;
x = -1.528 and y = 6.151
If (a, b) are coordinates of vertex H, then;
(a + 3)/2 = -1.528 and (b + 5)/2 = 6.151
Thus;
a = -6.056 and b = 7.302

Answer:
[tex](x-3)({x}^{2}+1)(x+2)[/tex]
Step-by-step explanation:
1) Factor [tex]x^4 - x^3 - 5x^2 - x - 6[/tex] using Polynomial Division.
1 - Factor the following.
[tex]x^4 - x^3 - 5x^2 - x - 6[/tex]
2 - First, find all factors of the constant term 6.
[tex]1, 2, 3, 6[/tex]
3 - Try each factor above using the Remainder Theorem.
Substitute 1 into x. Since the result is not 0, x-1 is not a factor..
[tex]1^4 - 1^3 - 5 * 1^2 - 1 - 6 = - 12[/tex]
Substitute -1 into x. Since the result is not 0, x+1 is not a factor..
[tex]( - 1 ) ^ 4 - ( - 1 ) ^ 3 - 5 ( - 1 ) ^ 2 + 1 - 6 = - 8[/tex]
Substitute 2 into x. Since the result is not 0, x-2 is not a factor..
[tex]{2}^{4}-{2}^{3}-5\times {2}^{2}-2-6 = -20[/tex]
Substitute -2 into x. Since the result is 0, x+2 is a factor..
[tex]{(-2)}^{4}-{(-2)}^{3}-5{(-2)}^{2}+2-6 = 0[/tex]
⇒ [tex]x+2[/tex]
4 - Polynomial Division: Divide [tex]{x}^{4}-{x}^{3}-5{x}^{2}-x-6[/tex] by [tex]x+2[/tex]

(x - h)²/4b² + (y - k)²/b² = 1 and (x - h)²/b² + (y - k)²/4b² = 1To answer the question, we need to know what an ellipse is.
What is an ellipse?An ellipse is part of a conic section.
The equation of the ellipseThe equation of an ellipse centered at (h,k) with major axis on the x-axis and major axis length, 2a and minor axis length 2b is
(x - h)²/a² + (y - k)²/b = 1
The equation of ellipse with major axis x-axis
The equations of ellipses whose major axis lengths are twice their minor axis lengths with ellipse centered at (h,k) with major axis on the x-axis. Since the major axis is twice the length of the minor axis, a = 2b.
So, (x - h)²/a² + (y - k)²/b² = 1
(x - h)²/(2b)² + (y - k)²/b² = 1
(x - h)²/4b² + (y - k)²/b² = 1
The equation of ellipse with major axis y-axis
The equations of ellipses whose major axis lengths are twice their minor axis lengths with ellipse centered at (h,k) with major axis on the y-axis. Since the major axis is twice the length of the minor axis, a = 2b.
So, (x - h)²/b² + (y - k)²/a² = 1
(x - h)²/b² + (y - k)²/(2b)² = 1
(x - h)²/b² + (y - k)²/4b² = 1
So, the equations of ellipses whose major axis lengths are twice their minor axis lengths are

Which statement about odd functions is correct?
A. They are symmetric over the x-axis.
B. They have rotational symmetry.
C. They are symmetric over the y-axis.
D. They are transformations of the parent function.
No one because odd functions are symmetric about the origin.
What is an odd function?It is a function such that f (x) =f (x) with the sign reversed but the absolute value unchanged if the independent variable's sign is reversed.
If f(x) Equals f(x) for every x, a function is odd. An odd function's graph will be symmetrical around the origin.
For instance, f(x) = x3 is an odd number. That is, the function on one side of the x-axis is sign inverted in relation to the function on the other side, or graphically, symmetric about the origin.
Therefore the odd functions are symmetric about the origin.

A boat can travel 28 miles up a river in the same amount of time it takes to travel 36 miles down the same river. If the current is traveling at 2 miles per hour, what is the speed of the boat in still water?
Answer:
16 mph
Step-by-step explanation:
You want the speed of a boat in still water if it travels 28 miles upstream in the same time it travels 36 miles downstream in a river that runs 2 mph.
TimeThe relation between time, speed, and distance is ...
t = d/s
If we let b represent the boat speed, the two identical times give the relation ...
28/(b -2) = 36/(b +2)
Solution28(b +2) = 36(b -2) . . . . cross multiply
28b +56 = 36b -72 . . . . eliminate parentheses
128 = 8b . . . . . . . . . . . . add 72 -28b
16 = b . . . . . . . . . . . . divide by 8
The speed of the boat is 16 mph.

Hi there! Please take a look at the following explanation and let me know in the comment if you have any doubts!
Given:We are given the radius that’s equal to 12 inches and π = 3.14
Problem:We want to find the circumference.
Circumference Formula:[tex]\displaystyle \large{C=2\pi r}[/tex] which simply means circumference = 2*π*radius or sometimes can also be written as [tex]\displaystyle \large{C=\pi d}[/tex] which means circumference = π*diameter since 2r means two times of radius and that’s technically diameter.
Step:Determine the following:
π = 3.14 as givenr = 12 as givenApply the circumference formula.
[tex]\displaystyle \large{C=2\cdot 3.14 \cdot 12}\\\\\displaystyle \large{C = 24 \cdot 3.14}\\\\\displaystyle \large{C=75.36}[/tex]
