72°Step-by-step explanation:
Let us assume the angle be xo Then it’s complement angle is 4x°.When the sum of two angles is 90°, then the angles are known as complementary angles. If two angles add up to form a right angle, then these angles are referred to as complementary angles.4x + x = 90° 5x = 90°x = 18° ∴ The angle x = 18° andIts complement 4x = (4×18o) = 72°Stay safe, stay healthy and blessedHave a good day !Good luck for ur assignment.Thank youWhat is the solution of log3x-2 4096=3
Sum interior angle on a regular pentagon
Answer:
540°
Step-by-step explanation:
Formula: note that n means nr of sides

(5-2)×180°=3×180=540°
Where each angle are 540°÷5=108°
Answer:
540
Step-by-step explanation:
108 is one interior angle from a regular pentagon
And a pentagon has 5 interior angles
So 180x5=540

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).
The parent cosine function is transformed to create the function . which graphed function has the same amplitude as function m?
Based on the graph given, the option that will show the same amplitude as function m is graph D.
Which graphed function is this about?The cosine function is seen as:
f(x) = A*cos(kx) + M
And the functions are:
A stands for amplitude, k is angular frequency,M is the midline.When the function is m(x) = -2*cos(x+π).
The absolute value of the amplitude will be 2*|-2| = 4

The probability of not picking a red marble is 0.2.
The probability of picking a yellow or green marble is 0.5
The probability of drawing an even number of a number greater than 4 is 1.
The probability of getting heads and an even number is 1.
The probability of drawing a 2 or a 4 is 0.25.
What are the probabilities?Probability determines how likely it is for an event to happen. The chances of the event occurring lies between 1 and 0.
The probability of not picking a red marble = (number of all the marbles - red marbles) / total marbles
4/20 = 0.2
The probability of picking a yellow or green marble = (number of yellow marbles / total number of marbles) + (number of green marbles / total number of marbles)
2/20 + 8/20 = 10/20 = 0.5
The probability of drawing an even number of a number greater than 4 = (number of even numbers / total numbers) + (numbers greater than 4 / total numbers)

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]
[tex]x^3[/tex] [tex]-3x^2[/tex] [tex]x[/tex] [tex]-3[/tex]

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.

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.

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

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;

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 ...

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]
