Find the area of the regular polygon with the given radius or apothem. Why is the area?
Answer:56.52
Step-by-step explanation:2x3.14=6.28
6.28x3=18.84
18.84x3=56.52
The area of the given polygon is 11.7 cm².
Given is an equilateral triangle with radius of 3 cm, we need to find the area of the polygon,
The radius of a circumcircle of an equilateral triangle is equal to a/√3, where a is the side length of the equilateral triangle.
So,
a/√3 = 3
a = 3√3
Now the side length is 3√3 cm.
Now, the area of an equilateral triangle is:
A = √3 / 4 × side²
= √3 / 4 × (3√3)²
= √3 / 4 × 27
= 11.7 cm²
Hence the area of the given polygon is 11.7 cm².

Which of these strategies would eliminate a variable in the system of equations?
( 6x + 5y = 1
16x - 5y = 7
Choose all answers that apply:
Answer:
B) Subtract the bottom equation from the top equation.
C) Add the equations.
Step-by-step explanation:
Let us analyze each of the options to see which one of them work.
A) Multiply the top equation by 7, then subtract the bottom equation from the top equation.
Multiplying the top equation by 7 gives:
7 * (16x + 5y) = (1 * 7)
112x + 35y = 7
Then, subtracting the bottom equation from this:
112x + 35y = 7
- (16x - 5y = 7)
=> 112x + 35y - 16x + 5y = 7 - 7
112x - 16x + 35y + 5y = 0
96x + 40y = 0
This method didn't eliminate any variable, so it didn't work for us.
B) Subtract the bottom equation from the top equation
This will yield:
16x + 5y = 1
- (16x - 5y = 7)
=> 16x + 5y - 16x + 5y = 1 - 7
16x - 16x + 5y + 5y = -6
0x + 10y = -6
10y = -6
y = -6 / 10
Hence, one variable has been eliminated. It works.
C) Add the equations
This yields:
16x + 5y = 1
+ 16x - 5y = 7
32x + 0y = 8
32x = 8
=>x = 8 / 32 = 1 / 4
This method works since one variable has been eliminated.

what is 6x-6 degrees
The expression '6x - 6 degrees' is a linear algebraic function possibly related to geometry, where degrees might denote the measure of an angle.
Explanation:The expression 6x - 6 degrees represents a linear function where x is typically a variable that stands for an unknown value to be determined, or it can represent an input into the function. The term degrees suggests that it may be related to angles in a geometric context. This expression simplifies to 6 times x minus 6 degrees, where the degrees could represent the measurement of an angle in geometry, or possibly a temperature dependent on the context, which is not provided here. When dealing with geometric problems, one often converts these expressions to a standard measurement, such as converting to radians or using decimal degrees for precision.

Answer: x = 4
Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is 4x.
To isolate 4x, we have to get rid of the -7 by adding
7 to both sides of the equation.
That leaves us with 4x = 16.
Now divide both sides by 4 to find that x = 4.

What is the ratio of the volume of the cone to the volume of the square pyramid?
Answer:
The ratio of the volume of cone to square pyramid is π or 3.14
Step-by-step explanation:
Given
Shapes: Cone and Square Pyramid
Diameter of the cone, d = 10 inches
Height of the cone, h = 12 inches
Height of the pyramid, h = 12 inches
Base edge of the pyramid, a = 5 inches
Required:
Ratio of the volume of cone to square pyramid.
First, we calculate the volume of each shapes
Volume of a cone is calculated as follows;
Volume = ⅓πr²h
Where r = radius = ½d
Recall that d = 10 inches
So, r = ½ * 10 inches
r = 5 inches.
Hence,
Volume = ⅓ * π * 5² * 12
Volume = ⅓ * π * 25 * 12
Volunteer = π * 25 * 4
Volume = 100π in³
Calculating Volume of the pyramid.
Volume = ⅓a²h
Recall that a = 5 and h = 12
So, Volume = ⅓ * 5² * 12
Volume = ⅓ * 25 * 12
Volume = 25 * 4
Volume = 100 in³
Now that both volumes have been calculated.
The ratio of the volume of cone to square pyramid is calculated by dividing the volume of the cone by the volume of the square pyramid.
Ratio = 100π ÷ 100
Ratio = π
Taking π as 3.14
Ratio = 3.14
Hence, the ratio of the volume of cone to square pyramid is π or 3.14
what is the x value of the vertex called
Answer:
The vertex form of a quadratic is given by
y = a(x – h)^2 + k, where (h, k) is the vertex. h may act as "x" in this case.
Step-by-step explanation:
The vertex form of a quadratic is given by
y = a(x – h)^2 + k, where (h, k) is the vertex.
You must simply get an equation in this format to find h and k.
The x value of the vertex in a parabola is found using the formula -b/(2a), which represents the x-coordinate of the vertex, a critical point that determines the parabola's maximum or minimum value.
The x value of the vertex in a parabola is a critical point that determines the maximum or minimum of the quadratic function. In a quadratic equation of the form f(x) = ax^2 + bx + c, the x-coordinate of the vertex can be found using the formula -b/(2a). This formula is derived from completing the square or using calculus to find the critical points of the function. Once you determine the x-coordinate of the vertex, you can substitute it back into the original equation to find the corresponding y-coordinate, giving you the full coordinates of the vertex of the parabola.
Ettiene solved a quadratic equation. His work is shown below.
In which step did Ettiene make an error?
The Step 2 shows the mistake done by Ettiene.
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0 .
It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem.
Given:
The given equation is x(x+4)=117.
Step1: x²+4x=117
Now, b/2 =4/2 =2
Then, add 2² to both the sides of an equation, we get
x²+4x+2²=117+2²
x²+4x+4=117+4
(x+2)²=121
x+2=±√121
x+2=±11
x=±11-2
x=11-2=9 and x=-11-2=-13

Which events are mutually exclusive ? Choose all that apply
The events that are mutually exclusive are Landing on a shaded sector and landing on the number three and Landing on an unshaded sector and landing on a number less than 2.
Mutually exclusive means that a combination of occurrences can never occur.
a) landing on a number greater than three while in a shaded area:
This is possible; for example, you could land in the 4.
b) landing in an even number on a dark sector.
Again, sector 4 is an even number and a shaded sector, thus these events do not conflict.
c) uncolored and odd number
This event is not mutually exclusive because you can land in the 3, which is unshaded and an odd number.
d) Landing on a shaded sector and landing on the number three
Because 3 is an unshaded sector, you can never land in 3 and a shaded sector at the same time; the two are mutually exclusive.
e) Landing on an unshaded sector with a number less than two.
Because 1 is the only integer smaller than 2, and sector 1 is darkened, these events are mutually exclusive.

C) 11
D) 20
ОА
Ов
Answer:
The answer is C.
Step-by-step explanation:
In order to find the value of expression, you first have to solve x by substracting 6 to both sides then divide it by 5 :
[tex]5x + 6 = 10[/tex]
[tex]5x + 6 - 6 = 10 - 6[/tex]
[tex]5x = 4[/tex]
[tex]5x \div 5 = 4 \div 5[/tex]
[tex]x = \frac{4}{5} [/tex]
Next, you have to substitute the value of x into the expression :
[tex]let \: x = \frac{4}{5} [/tex]
[tex]10x + 3[/tex]
[tex] = 10( \frac{4}{5} ) + 3[/tex]
[tex] = 8 + 3[/tex]
[tex] = 11[/tex]
What are the solutions of 2x2 - 6x + 5 = 0 ?
Final answer:
(Option C: (3 + i)/2 and (3 - i)/2
The solutions to the quadratic equation 2x^2 - 6x + 5 = 0 are 1.5 + 0.5i and 1.5 - 0.5i, as the discriminant is negative and indicates there are no real solutions, only complex ones.
Explanation:
The solutions of the quadratic equation 2x2 - 6x + 5 = 0 can be calculated using the quadratic formula, which is:
x = (-b ± √(b2 - 4ac)) / (2a)
For the given equation, a = 2, b = -6, and c = 5. Plugging these values into the quadratic formula, we get:
x = (6 ± √((-6)2 - 4(2)(5))) / (2(2))
x = (6 ± √(36 - 40)) / 4
x = (6 ± √(-4)) / 4
Since the discriminant (b2 - 4ac) is negative, this equation has no real solutions and two complex solutions. The final solutions are:
x = (6 ± 2i) / 4
x = (3 ± i)/ 2
x = 1.5 ± 0.5i
The solutions are 1.5 + 0.5i and 1.5 - 0.5i.

What should be true about the divisor (the number you are dividing by) in order for synthetic division to be
pretty straightforward?
Answer:
In order for synthetic division to be pretty straightforward, the divisor must be of the first degree (that is, the power of x must be exactly one.) and must have the binomial form x - a.
Unlike Long Division which makes use of the polynomials given directly, Synthetic Division makes use of the coefficients of this polynomials.
Find the volume of the cone.round to the nearest tenth. Height: 10 radius:2
Answer:
41.9 units³
Step-by-step explanation:
(please see attached for reference)
The volume of a cone is given by:
V = (1/3) πr²h where,
V = volume (we are asked to find this)
π = 3.142
r = radius = given as 2
h = height = given as 10

Answer:
x= 103°
Step-by-step explanation:
The angle next to angle x is 77° because it is a corresponding angle to the original 77° angle (corresponding angles is basically a pair that lies in the same position as each other, as is the case with the 77° angle and the angle to the right of x°).
Now that we know that the adjacent angle to x is 77°, you can find x. Note that the line x and 77° are lying on is parallel. This means that they are supplementary angles, which means that the sum of both angles is equal to 180°. Insert this into an equation:
[tex]180=x+77[/tex]
Solve for x. Use inverse operations to subtract 77 from both sides:
[tex]180-77=x+77-77\\\\180-77=x[/tex]
Simplify subtraction:
[tex]103=x[/tex]
x is 103°.
