Step-by-step explanation:

<em>Given </em>

<em>circumference </em><em>=</em><em> </em><em>1</em><em>2</em><em> </em><em>inch</em>

<em>π</em><em> </em><em>=</em><em> </em><em>3</em><em>.</em><em>1</em><em>4</em>

<em>radius </em><em>(</em><em>r) </em><em> </em><em>=</em><em> </em><em>?</em>

<em>We </em><em>know </em>

<em>circumference </em><em>=</em><em> </em><em>2</em><em>π</em><em>r </em>

<em>1</em><em>2</em><em> </em><em> </em><em>=</em><em> </em><em>2</em><em>*</em><em> </em><em>3</em><em>.</em><em>1</em><em>4</em><em> </em><em>*</em><em> </em><em>r</em>

<em>r </em><em>=</em><em> </em><em>1</em><em>2</em><em> </em><em>/</em><em> </em><em>6</em><em>.</em><em>2</em><em>8</em>

<em>Therefore </em><em> </em><em>r </em><em>=</em><em> </em><em>1</em><em>.</em><em>9</em><em>1</em><em> </em><em>inch</em>

Find two positive consecutive integers whose product is 132.
iren2701 [21]
If x is the first integer, then x+1 is the second. x(x+1)=132 or x^2+x-132=0. This factors as (x-11)(x+12)=0. Thus either x=11 or x=-12 
<span>So either 11 and 12 or -12 and -11 will do.</span>

What is the equation for the line of reflection that maps the trapezoid onto itself? Enter your answer in the box______
nadezda [96]
Y = -1

It is an isosceles trapezoid, which is just as well, otherwise it could not reflect onto itself. The line of reflection is the same as the mirror line which is the same as the axis of symmetry.

It runs horizontally exactly through the middle of the shape.

All horizontal lines have the equation y = a value

In this case the line is <span>y=−<span>1</span></span>
