This would be an exponential decay model.
3x - 12 = -15
Add 12 on both sides.
-12 + 12 = 0
-15 + 12 = -3
The equation is now 3x = -3.
Divide both sides by 3 to isolate the variable.
3x / 3 = x
-3 / 3 = -1
So, x = -1.
Answer:
The answer is 8:343.
Step-by-step explanation:
We can use Galileo's square cube law to calculate the ratio between two similar pyramids. The law is used to describe the change of the area or the volume of the shape when their dimensions increase or decrease:
V₁ and V₂ - volumes of pyramids,
l₁ and l₂ - the edges of pyramids.
