Find the number of sides of a regular polygon if one interior angle us 60 degrees

iren [92.7K]

360°÷n = number of sides of a regular polygon.

n= one of the exterior angle of a regular polygon.

180°-60°=120°
n=120°

360°÷120°= 3

What kind of shift does the graph have? y = -sin (x-1) from y = sin(x)

now, with that template in mind, let's see

$\bf \begin{array}{lllll}

\\\\\\
\textit{horizontal shift of }\cfrac{C}{B}\implies \cfrac{-1}{1}\implies -1
\\\\\\
\textit{A is negative, so is flipped upside-down}$

Amelia had $175,000 in a CD at Treasure Trove Bank, which just failed. If the FDIC insurance limit per depositor per bank is $25

uysha [10]

Answer:

The correct option is A. Amelia will get $175,000.

Step-by-step explanation:

It is given that Amelia had $175,000 in a CD at Treasure Trove Bank, which just failed and FDIC insurance limit per depositor per bank is $250,000.

It means the FDIC insurance company will settle the loss till $250,000.

If the deposited amount of depositors is less than $250,000, then they will get their total deposited amount and if the deposited amount of depositors is greater than or equal to $250,000, then they will get only $250,000.

Since the deposited amount of Amelia is $175,000, which is less than $250,000, therefore she will get her total deposited amount.

$175,000$

Therefore correct option is A. Amelia will get $175,000.

Zoe, Latoya, Christina, and Rhoda each used a different method to verify that Negative 2 (3 x minus 12) = negative 6 x + 24. Zoe

kow [346]

Answer:

d) Rhoda's method

Step-by-step explanation:

We are given an Algebraic expressions

Negative 2 (3 x minus 12) = negative 6 x + 24.

= -2(3x - 12) = -6x + 24

Distributive property states that:

a(b - c) = ab - ac

2(3x - 12) = -2 × 3x - (-2 ×12)

= -6x + 24

From the above question, we can deduce the following information:

a) Zoe

Step 1

Substitute opposite values of x into both expressions.

2(3x - 12) = -6x + 24

Lets say x = 1, opposite of 1 = -1

Hence

2(3 × 1 - 12) = -6(-1) + 24

-2(3 - 12) = 6 + 24

-6 + 24 = 6 + 24

18 ≠ 18

Step 2.

The expressions are equivalent if the values of the expressions are equal.

Zoe is wrong

b) Latoya

Step 1

Substitute the same value of x into both expressions.

Step 2

The expressions are equivalent if the value of one of the expressions is zero.

Latoya is wrong

c) Christina

Step 1

Substitute opposite values of x into both expressions.

Step 2

The expressions are equivalent if the values of the expressions are opposites.

Christina is wrong

d) Rhoda

Step 1

Substitute the same value of x into both expressions

-2(3x - 12) = -6x + 24

Let say x = 1

-2(3 × 1 - 12) = -6(1) + 24

-2(3 - 12) = -6 + 24

-6 + 24 = -6 + 24

18 = 18

Step 2

The expressions are equivalent if the values of the expressions are equal.

Therefore, Rhoda method is correct
