PolarNik [594]

We have that
<span>Circle 1: center (8, 5) and radius 6
</span><span>Circle 2: center (−2, 1) and radius 2

we know that
the equation of a circle is
(x-h)</span>²+(y-k)²=r²
for the circle 1---------> (x-8)²+(y-5)²=36
for the circle 2---------> (x+2)²+(y-1)²=4

using a graph tool
see the attached figure

Part A)<span>What transformations can be applied to Circle 1 to prove that the circles are similar?

we know that

<h2>Hello!</h2>

The answer is:

The area of this figure is 946 square inches.

<h2>Why?</h2>

We can see that the figure is composed by two rectangles with diferrent dimensions, so, to calculate the area of the entire figure.

So,

For the first rectangle, we have:

$Base=7in\\Height=28in$

The area will be:

$Area=Base*Height=7in*28in=196in^{2}$

For the second rectangle, we have:

$Base=25in\\Height=30in$

The area will be:

$Area=Base*Height=30in*25in=750in^{2}$

Now, calculating the area of the entire figure, we have:

$TotalArea=FirstRectangleArea+SecondRectangleArea\\\\TotalArea=196in^{2}+750in^{2}=946in^{2}$

Have a nice day!

Find the remainder when f(x) is divided by (x - k).<br><br> f(x) = 4x3 - 6x2 + 3x + 1; k= -2

laila [671]

$\frac{f(x)}{(x-k)}$
$\frac{4x^3-6x^2+3x+1}{(x+2)}$
Using Long Division, pic below
Your remainder is -61

. The perimeter of a rectangle is 38 inches. If the length is 3 inches more than the width, find the width.

nikdorinn [45]

Answer:

w = 8 inches

Step-by-step explanation:

P = 2w + 2l

l = 3 + w

38 = 2w + 2(3 + w)

38 = 2w + 6 + 2w

38 - 6 = 4w

32 = 4w

w = 32 : 4

w = 8 inches

l = 3 + w

l = 3inches + 8inches

l = 11 inches

The intensity, I, of a sound varies inversely with the square of the distance, r, from the source of the sound. Write an equatio

charle [14.2K]

Answer:The equation relating I, r, and k is I =K/r²

Step-by-step explanation:

The intensity, I, of a sound varies inversely with the square of the distance, r, from the source of the sound can be written as

I ∝ 1/r²

Introducing the constant of proportionality, K we have that

I =K x 1/r²

Therefore , the equation relating I, r, and k is I =K/r²
