please help :) find the area of the regular polygon
9514 1404 393
Answer:
3√3 square units
Step-by-step explanation:
The area of a regular n-sided polygon with radius r is given by the formula ...
A = (n/2)r²·sin(360°/n)
For n=3 and r=2, the area is ...
A = (3/2)(2²)·sin(360°/3) = 6·sin(120°) = 6(√3/2)
A = 3√3 . . . . square units
_____
Alternate solution
The center of this polygon is the centroid, which divides each median into parts with the ratio 2:1. This means the given radius is 2/3 of the height of the triangle. The base of the triangle is 2/√3 times the height, so is ...
b = (2/√3)(3) = 2√3
The area using these dimensions is calculated as ...
A = 1/2bh
A = 1/2(2√3)(3) = 3√3 . . . . square units

The triangle below is equilateral. Find the length of side x in simplest radical form with a rational denominator.
Answer:
x = √30
Step-by-step explanation:
For an equilateral triangle, the measure of the angle at each vertex is 60 degrees
Thus, the angle 60 faces the side measure x
Also, the given length is adjacent to the angle 60 measure
Mathematically, the trigonometric ratio that links the adjacent and the opposite is the tan
The tan is the ratio of the opposite to the adjacent
Thus;
Tan 60 = x/ root 10
x = root 10 * tan 60
x √(10 * √(3
x = √30
The length of [tex]x[/tex] is required.
The length of [tex]x[/tex] is [tex]\sqrt{30}\ \text{units}[/tex]
In an equilateral triangle the altitude divides the side into halves.
So, the hypotenuse will be [tex]\sqrt{10}+\sqrt{10}=2\sqrt{10}[/tex]
From the Pythagoras theorem we have
[tex]x^2+(\sqrt{10})^2=(2\sqrt{10})^2\\\Rightarrow x=\sqrt{(2\sqrt{10})^2-(\sqrt{10})^2}\\\Rightarrow x=\sqrt{30}[/tex]
The length of [tex]x[/tex] is [tex]\sqrt{30}\ \text{units}[/tex]

There is a bag filled with 5 blue and 4 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 blues?
Answer:
total balls 5+4 = 9
Probability of getting blue ball in the first try
=[tex]\frac{5}{9}[/tex]
After replacing, total number of balls = 9
Probability of getting blue ball in the second try
[tex]= \frac{5}{9}[/tex]
Therefore probabilty of getting 2 blue balls
=[tex]\frac{5}{9}*\frac{5}{9} =\frac{25}{81}[/tex]

2(n-1)+ 4n= 2 (3n -1)
Answer:
Infinitely many solutions.
Step-by-step explanation:
2 (n - 1) + 4n = 2 (3n - 1) Let's simplify this to solve it.
2n - 2 + 4n = 6n - 2 Distribute 2(n-1) and 2(3n-1)
2n + 4n - 2 = 6n - 2 Rearrange the left side of the equation.
6n - 2 = 6n - 2 Add 2n + 4n.
-6n -6n Subtract 6n from both sides.
-2 = -2
the answer is infinitely many solutions, meaning that n can be any real number.

Match each interval with its corresponding average rate of change for q(x) = (x + 3)2.
1. -6 ≤ x ≤ -4
2. -3 ≤ x ≤ 0
3. -6 ≤ x ≤ -3
4. -3 ≤ x ≤ -2
5. -4 ≤ x ≤ -3
6. -6 ≤ x ≤ 0
A)-1
B)1
C)3
D)-3
E)0
F)-4
Answer:
When we have a function:
f(x)
The average rate of change in the interval a < x < b
is given by:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
Now for each of the given intervals, let's find the average rate of changes.
q(x) = (x + 3)^2
1) -6 ≤ x ≤ -4
[tex]r = \frac{(-4 + 3)^2 - (-6 + 3)^2}{-4 - (-6)} = \frac{1 - 9}{2} = -4[/tex]
here the correct option is F.
2) -3 ≤ x ≤ 0
[tex]r = \frac{(0 + 3)^2 - (-3 + 3)^2}{0 - (-3)} = \frac{9}{-3} = -3[/tex]
Here the correct option is D.
3) -6 ≤ x ≤ -3
[tex]r = \frac{(-3 + 3)^2 - (-6 + 3)^2}{-3 - (-6)} = \frac{9}{3} = 3[/tex]
Here the correct option is C
4) -3 ≤ x ≤ -2
[tex]r = \frac{(-2 + 3)^2 - (-3 + 3)^2}{-2 - (-3)} = \frac{1}{1} = 1[/tex]
Here the correct option is B.
5) -4 ≤ x ≤ -3
[tex]r = \frac{(-3 + 3)^2 - (-4 + 3)^2}{-3 - (-4)} = -1/1 = -1[/tex]
Here the correct option is A
6) -6 ≤ x ≤ 0
[tex]r = \frac{(0 + 3)^2 - (-6 + 3)^2}{0 - (-6)} = \frac{9 - 9}{6} = 0[/tex]
Here the correct option is E.

The exponent function will be f(x) = 1/3 (4)ˣ. Then the correct option is C.
What is an exponent?Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as
y = a(b)ˣ
At x = 1, the value of y will be 4/3. Then we have
4/3 = ab ...1
At x = 2, the value of y will be 16/3. Then we have
16/3 = ab² ...2
From equation 1 and 2, we have
b = 4 and a = 1/3
Then the function will be
f(x) = 1/3 × (4)ˣ.
Then the correct option is C.

Find all solutions to the equation. cos x = -1/2
Answer:
^^
Step-by-step explanation:
Answer:
You didn't add the range. I'll use (0<x<2π)
cosx = -1/2
x=-cos-¹(1/2)
x= -60°
Cosine is negative in the second and 3rd quadrants
180-x ---- Second quadrant
x+180 ----- 3rd quadrant
So
Our answer
180-(-60)=240° or 4π/3 second quad
180+(-60) = 120° or 2π/3---- 3rd quad

Answer:
24
Step-by-step explanation:
h(x) = [tex]\frac{1}{2}[/tex]x - 5, x < 0 This formula would be used for h(-30). Since -30 is less than 0.
h(x) = [tex]\frac{1}{2}[/tex]x - 5, x < 0 ← You can now ignore the x<0.
h(-30) = [tex]\frac{1}{2}[/tex](-30) - 5 Input the -30 as x.
h(-30) = [tex]\frac{-30}{2}[/tex] - 5 Simplify
h(-30) = -15 - 5 Simplify further
h(-30) = -20
Next
h(x) = [tex]\frac{1}{5}[/tex]x - 2, x < 0 This formula would be used for h(30). Since 30 is greater than 0.
h(x) = [tex]\frac{1}{5}[/tex]x - 2, x ≥ 0 ← You can ignore the x≥0.
h(30) = [tex]\frac{1}{5}[/tex](30) - 2 Input the 30 as x.
h(30) = [tex]\frac{30}{5}[/tex] - 2 Simplify
h(30) = 6 - 2 Simplify further
h(30) = 4
Finally the problem is asking for h(30) - h(-30) = ?
h(30) - h(-30)
(4) - (-20) Substitute the value of h(30) and the value of h(-30).
4 + 20 You distribute the - sign into the parentheses. A negative times a
24 negative is a positive. That is how the equation had become 4 + 20 towards the end. Which is equal to 24.
So the answer is 24.

Answer:
Volume Original = 471 in³
Volume New = 343.36 in³
Step-by-step explanation:
Radius Original = 5
Radius New = (5) - 0.1(5) = 5 - 0.5 = 4.5
Height original = 6
Height new = (6) - 0.1(6) = 6 - 0.6 = 5.4
Volume original = 3.14 x 25 x 6 = 3.14 x 150 = 471
Volume New = 3.14 x 20.25 x 5.4 = 343.36
