Answer:
i
Step-by-step explanation:
i=√-1
53.24-34.99=18.25
$1 will buy 20 minutes of long distance calling
x$18.25 = 365 minutes @ $34.99
$132-$34.99=$97.01
20x97=1,940 minutes
minimum=365 minutes
maximum=1,940 minutes
Hope this helps.
Answer:
Step-by-step explanation:
y-y1 = m(x-x1)
y-4 = 2(x-3)
y-4=2x-6
y= 2x -6+4
y=2x-2
Equation of a circle is:
<span>(x−h<span>)2</span>+(y−k<span>)2</span>=<span>r2</span></span>
h is the x-coordinate of the center and k is the y-coordinate of the center. Even though the formula has minus signs, those are positive numbers. If there were plus signs in there, the numbers h and k would actually be negative. Now since you're centered at the origin, that means h and k are 0, so you'd just have this:
<span><span>x2</span>+<span>y2</span>=<span>r2</span></span><span>
Now since your radius is 7, just square it and replace r^2 woth that value :)</span>
