Answer:
c
Step-by-step explanation:
<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

Answer:
1.) $1
2.)$4
3.)$12
4.)3/4
Step-by-step explanation:
32(.5)=16
she had 16 left after lunch. 16(.25)=4
16-4=12
1/2=2/4
2/4+1/4=3/4
42 square inches.
Step-by-step explanation:
A = 1/2 b × h
A = 1/2 x 12 x 7
A = 6 × 7
A = 42
