M<x + m<GDE = 90°
m<x + 40 = 90°
m<x +40 -40 = 90° -40
m<x =50

m<y + m<FCA
m<y + 55 = 180°
m<y +55 - 55 =180 -55
m<y = 125

<span>C. m∠x = 50°
    m∠y = 125°</span>

A round mirror has a radius of 5.3 inches. What is the area of the mirror in square inches, rounded to the nearest tenth?
GrogVix [38]

Answer:

88.2 squared

Step-by-step explanation:

The formula to find the area of a circle is <em>a = pi * r ^2</em>

Let's replace the values that we know.

a = 3.14 x 5.3 ^2

First, we should do 5.3 ^2, which is 28.09.

a = 3.14 x 28.09

Now we are able to do 3.14 x 28.09 which is 88.2026

But that isn't it! We need to round to the nearest tenth, which is this digit:

88.<u>2</u>026

Since next to the 2 there is a 0, you take out all the numbers after that 2. Which leaves you with:

88.2

20 points for this question:<br><br> Find the domain.
Yuliya22 [10]

Answer:

The Domain D = {y ∈ R / y ≠ \dfrac{b}{2} y ≠ 0}

Step-by-step explanation:

Let ,

f(y) = \dfrac{b^{2} - 4by }{2y^{2} - by } - \dfrac{4y}{b-2y}

The above function would be defined only when the denominator of anyone or both the terms of the function do not become 0 -

2y^{2} - by ≠ 0 and b - 2y ≠ 0

∴ y(2y - b) ≠ 0                 and y ≠\dfrac{b}{2}

Either y ≠ 0 or y ≠ \dfrac{b}{2}

∵ The domain of a function consists of only those points where the function is defined -

The Domain D consists of all y ∈ Real numbers such that y ≠ 0 and y ≠ \dfrac{b}{2}
