Answer:
a <= 3
Step-by-step explanation:
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
Answer:
no.
Step-by-step explanation:
Answer:
x = 60°
Step-by-step explanation:
since, the triangles are complementary the sum of their measures will be 90°
now,
Answer:
<h2>A</h2><h2 />
Step-by-step explanation:
m (slope) =<u> rise </u> = <u> y </u> = <u> y₁ - y₁ </u>
run x x₁ - x₁
to get y = mx
therefore, the answer to the question is :
A. The slope m is rise over run, so y over x =m.
Solve for y to get y=mx.
