Answer:yes. It i s correct
Step-by-step explanation:
First, find the midpoint of the diameter. the midpoint is the center of the circle.
[(-10+(-6)]/2=-8, [(-8+(-2)]/2=-5
so the center is at (-8, -5)
next, find the distance between the two points:
d=√[-6-(-10)]²+[-2-(-8)]²=√4²+6²=√52=2√13
half of the diameter is radius, r=half of 2√13=√13
standard equation for the circle is (x-h)²+(y-k)²=r², (h,k) being the center, r the radius
(x+8)²+(y+5)²=13 is the answer.
Answer:
The variable a is how many minutes late Albin is.
Step-by-step explanation:
10.50=0.50a+3
The 10.50 is the charge for the late pickup
The 3 dollars is a flat fee for being late
The 0.50 dollars per minute for being late
The variable a is how many minutes late Albin is.
I don't entirely know what you mean by 'rate of change', but I'll assume that you mean slope.
0, -4 and 3, 2 are on the coordinate plane.
From 0, we go over three to reach 3.
From -4, we go up six to reach 2.
Since slope is in essence, rise/run, we have the following fraction:
6/3, which can be re-written as 2/1 or just 2.
Hope this helps!
