Answer:
The circumference of the yellow circle is or approximately, the circumference of the blue circle is or approximately, the circumference of the green circle is or approximately, the circumference of the red circle is or approximately, and the circumference of the pink circle is or approximately.
Step-by-step explanation:
To find the circumference of a circle, you need to multiply the diameter of the circle and multiply it by . In this case, the circumferences of the yellow circle are or approximately , the circumference of the blue circle is or approximately , the circumference of the green circle is or approximately , the circumference of the red circle is or approximately , and the circumference of the pink circle is or approximately .

Step-by-step explanation:
We need to write this in the form y = mx + b.
x + 3y = -12
3y = -x - 12
Answer:
Step-by-step explanation:
-60
Step-by-step explanation:
Increase in population is given by positive sign
Change in population in 5 years = -300
Decrease in population is represented by negative sign
Change in population in 1 year = -300\5
= -60
Town's population faces a decrease of 60 residents each year.
Answer:
Step-by-step explanation:
∑⁴ₙ₌₁ -144 (½)ⁿ⁻¹
This is a finite geometric series with n = 4, a₁ = -144, and r = ½.
S = a₁ (1 − rⁿ) / (1 − r)
S = -144 (1 − (½)⁴) / (1 − ½)
S = -270
If you wanted to find the infinite sum (n = ∞):
S = a₁ / (1 − r)
S = -144 / (1 − ½)
S = -288
