60 Points for a rapid reply -calculate the measure of the central angle in the regular dodecagon {12 sides}
Answers
Answer:
Maybe 30°
Cause 12:4 is 3
3x10 30
The central angle of a regular dodecagon is 30 degrees. Option A is the correct option.
The central angle - The angle created at the polygon's center by two adjacent radii—the lines that connect the polygon's center to its vertices—is known as the central angle.
We know it is a regular dodecagon, which means all the sides will be of equal size.
As it is a dodecagon there will be a total of 12 equal central angles added to give an angle of 360 degrees.
Let's assume the central angle is x.
12x = 360
x = 360/12
x = 30
Hence, the central angle in a regular dodecagon is 30 degrees.

Solve the system of equations with elimination. Show ALL steps.
x+3y=4
x-2y= -1
They are the same equation, you have to find out what x equals and what y equals THANK YOUUUUU!!! :). NO DANG LINKS EITHER OR IMA MAKE SURE UR DELETED.
Answers
Answer:
(1 , 1)
Step-by-step explanation:
x+3y=4
x-2y=-1
We can solve this system of equations using the elimination method. In this method there must be two identical variables ( which in this case there is, that variable being x ). If there are two identical variables you can subtract the two equations "eliminating" one of the variables. There is then only one variable in which you can solve for.
So first let's subtract the two equations
x + 3y = 4
- ( x - 2y = -1 )
------------------
remove parenthesis and apply negative sign
x + 3y = 4
-x + 2y = +1
-----------------
0 + 5y = 5
We are now left with one variable in which we can solve for.
5y = 5
divide both sides by 5
y = 1
Next we want to find the value of x.
To do so we simply plug in the value of y into one of the equations and solve for x. Note that we could do this to either equation and we would get the same answer.
x + 3y = 4
y = 1
x + 3(1) = 4
multiply 3 and 1
x + 3 = 4
subtract 3 from both sides
x = 1
So x = 1 and y = 1
Therefore the solution to the system of equations is (1,1)
1) Base of an isosceles triangle is five more than three times the equal sides and perimeter of the triangle is 75 cm. Find the lengths of the sides of the triangle.
Answers
Answer:
Equal sides of triangle = 14 cm
Base of an isosceles triangle = 47 cm
Step-by-step explanation:
Given:
Perimeter of the triangle = 75 cm
Base of an isosceles triangle = five more than three times the equal side
Find:
Lengths of isosceles triangle
Computation:
Assume;
Equal sides of triangle = a
So,
Base of an isosceles triangle = 3a + 5
Perimeter of the triangle = Base of an isosceles triangle + 2[Equal sides of triangle]
Perimeter of the triangle = 3a + 5 + 2[a]
Perimeter of the triangle = 5a + 5
75 = 5a + 5
5a = 70
a = 14
Equal sides of triangle = 14 cm
Base of an isosceles triangle = 3a + 5
Base of an isosceles triangle = 3(14) + 5
Base of an isosceles triangle = 42 + 5
Base of an isosceles triangle = 47 cm

The values of the trigonometric ratios sec θ and cot θ are:
sec θ = -13/12
cot θ = 12/5
How to use Trigonometric ratios?There are three main trigonometric ratios which are:
sin x = opposite/hypotenuse
cos x = adjacent/hypotenuse
tan x = opposite/adjacent
We are told that sin θ = -5/13
Using Pythagoras theorem, we have that:
Adjacent side = √(13² - 5²)
Adjacent side = √144 = 12
Thus:
cos θ = -12/13
sec θ = 1/cos θ
Thus:
sec θ = 1/(-12/13)
sec θ = -13/12
1/ tan θ = cot θ
tan θ = sin θ/cos θ
tan θ = (-5/13)/(-12/13) = 5/12
cot θ = 1/(5/12) = 12/5

Step-by-step explanation:
The top one on the second slide of graphs.
The correct graph is C which represents the given function f(x) = -12(x-0.5)²+3.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
The equation f(x) = -12(x-0.5)²+3 represents the height of an eraser cap launched from a mousetrap catapult on the floor over time in seconds (x).
The graph of this equation will be a downward-facing parabola, with the vertex at (0.5, 3) and an axis of symmetry at x = 0.5.
The maximum height reached by the eraser cap is 3 feet, which occurs at x = 0.5.
As time increases beyond 0.5 seconds, the height of the eraser cap decreases due to the negative coefficient of the squared term.
Therefore, the correct graph is C which represents the given function.

Answers
Answer:
\(\begin{gathered} C.\text{ Annual interest rate of ring= 3.96\%} \\ \text{ It is greater than the necklace that's why the value increases more.} \end{gathered}\)Step-by-step explanation:
It is given that the value of a necklace increases by 3.2% per year, then by the equation of future value, the value of the necklace after t years will be:
\(\begin{gathered} A(n)=1(1+\frac{3.2}{100})^t \\ \text{ The initial value is given} \end{gathered}\)Now, since the necklace after 1 year will be $1.032. From the following equation determine the value of the ring after 1 year:
\(\begin{gathered} A=1(1+\frac{0.33}{100})^{12} \\ A=\text{ \$1.04} \end{gathered}\)Therefore, the ring will value more after 1 year. This is because the ring has a greater annual rate than the necklace.
