Answer:
A)c=130/20
B)6.5 calories
Step-by-step explanation:
in one minute the calories burnt are
the equation would be
20 min.=130 calories
1 min.=?c
c=130÷20
part B=130÷20
=6.5 CALORIES
<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
