Answer:
49.6
Step-by-step explanation:
A = πr2, (Pi r-squared)
A = (3.14)(8)2
A = (3.14) (64)
A = 198.4
but you need to take 1/4th of that since you are only looking at 1/4th of the circle so,
.25 x 198.4 = 49.6
we know that the colony is doubling, namely the rate of growth is 100% of whatever is existent, thus

Answer:
The solution to this equation could not be determined.
Step-by-step explanation:
Simplifying
a(c + -1b) = d
Reorder the terms:
a(-1b + c) = d
(-1b * a + c * a) = d
(-1ab + ac) = d
Solving
-1ab + ac = d
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Combine like terms: d + -1d = 0
-1ab + ac + -1d = 0
The solution to this equation could not be determined.
Answer:
(3,-4)
Step-by-step explanation:
There is a graphing calculator called desmos that can help you answer questions like this, but, if you don't want to use that, you can just make a graph and imagine the transformation. Remember, when you reflect something over an axis, it is like you are folding the graph along the axis and your new point will be on the other side.
