Answer:
see below
Step-by-step explanation:
A = pi r^2
If they have the same radius they have the same area
A two circles = pi r^2 +pi r^2
= 2 pi r^2
If we double the radius
A = pi (2r)^2
= pi 4r^2
The combined area of two circles is 1/2 the area as the area of a circle with twice the radius.
Answer:
The expense of the visit to dental specialist is equivalent to (50+100n)
Step-by-step explanation:
Answer:
B, or second answer choice
Step-by-step explanation:
y -
= m(x -
)
y - 1/3 = 3/4 (x - 4)
B
Vertex form:
y = a(x - h)² + k
I have not learned this stuff yet, but by using online calculators, I can determine that the vertex form is:
Y = (x - 4)² - 19
I believe so :/
