The formula of interest is
  A = (1/2)r²·θ
You have r = 9 m, θ = 3π/5. Then the area is
  A = (1/2)(9 m)²(3π/5) = 24.3π m²

The sector area is ...
  A ≈ 76.3 m²

What is the algebraic expression for the following word phrase: the quotient of y and 6
rodikova [14]

A quotient is the answer that results from a number being divided by another number. In other words, it is the answer to a division problem. So, the quotient of y and 6 means that y is being divided by 6. Algebraically, you write this as y ÷ 6, or \frac{y}{6}

How to solve -13=5(1 4m)-2m?
Paladinen [302]
First, you would multiply: -13 = 70m - 2m. Then, you subtract the like terms, which would be 70m - 2m: -13 = 68m. You are looking for what m is, so you would divide 68 on both sides: m = - 13 / 68. In math, people would usually like fractions more than decimals, but if you are looking for the decimal number, it would be m ≈ - 0.19.

Given point B is located at
ELEN [110]

Answer: \Large\boxed{Point~B'~=~(-4,~-2)}

Step-by-step explanation:

<u>Given information</u>

Point B = (-2, -4)

Reflection line: y = x

<u>Concept:</u>

When reflecting over the line y = x, the position of y and x in the original coordinate switches places.

This is because it is " y = x ", assuming that they could interchange

<u>Find the coordinate of Point B'</u>

Original (x, y) = (-2, -4)

Point B' = (x', y') = (y, x) = \Large\boxed{(-4,~-2)}

<em>Please refer to the attachment below for a graphical understanding</em>

Hope this helps!! :)
