<span>1) distance formula; d = √(x2-x1)² +(y2-y1)² . d= √(-4-8)² +(-3-7)² = > d= 2√61
diameter = 2*radius => 2√61 =2r => r =√61 => r² =61
midpoint of the diameter is:
Xm= -4-8 /2 -6 => -6
Ym = -1-9 /2 -5 => -5 center of the cirlce is at (-6,-5)
</span><span>general equation of a circle: (x-x1)² +(y-y1)² =r² with (x1,y1) being the center of the circle.</span><span>
equation: (x+6)+(y+5)=61

To solve this for D you divide both sides by pi and get d=c/pi
Answer:
Reflection, Triangle B is a reflection of A
Step-by-step explanation:
Reflection <em>is when we flip a figure over.
</em>
Translation <em>is when we slide a figure in any direction.
</em>
Rotation <em>is when we rotate a figure a certain degree around a point.
</em>
Dilation <em>is when we enlarge or reduce a figure.</em>

Answer: it hink its Near integers
Step-by-step explanation:
Answer: 14
The number to the right of the decimal point is either 5 or greater than that, so the 13 is increased by 1 which results in 14.
