we are given two points as
(1.0, 2.0) and (1.0, 5.0)
so,
(x1, y1)= (1.0 , 2.0)
(x2, y2)= (1.0 , 5.0)
x1=1 , y1=2
x2=1 , y2=5
now, we can use distance formula

now, we can plug values
and we get




so, distance between points is 3...........Answer
The area of a circle is A = πr^2. We let A1 And A2 the areas of the circles and r1 and r2 the radius of each, respectivley.
A1 + A2 = 80π
Substitute the formula for the area,
π(r1)^2 + π (r2)^2 = 80π
From the statement, we know that r2=2(r1).
<span>π(r1)^2 + π (2 x r1)^2 = 80π
</span>We can cancel π, we will have
5 x (r1)^2 = 80
Thus,
r1 = 4 and r2 = 8
J is your answer.
Slope is rise over run + your Y intercept.
Your y- intercept is the point in the graph in which the line passes through, the line passes through -2, so you know -2 is going to be your answer at the end. And slope is rise/run.
From one point to another, you rise 1 time , and run over 3 so you know your answer is
y = 1/3x - 2
hope this helps :)
