The population decays by a factor of (1/2 )^1/4 every hour.
<h3>
Exponential Function</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y, b is the multiplier, y and x are variables.
Let y represent the bacteria population after x hours.
A bacteria population decreases by a factor of 1/2 every 4 hours.
The population decays by a factor of (1/2 )^1/4 every hour.

Because you can see all the mountains that are on the world and just understand it better<span />
Answer:
I'll assume you have to match the name with their definitions.
1. aquifers
underground water sources
That's because of the presence of porous rocks that let water pass through them and reach an underground cavern that then acts as a tank.
2. delta
a broad, triangular-shaped land area at the mouth of a river
That's common especially in larger rivers that meet their destination point (usually the ocean).
3. oasis
a small fertile area in the desert, usually a place where water is close to the surface (plural - oases)
We all heard about oases in the desert, where human and animals alike gather to drink.
4. rain shadow
an area that receives less precipitation because of its location on the leeward side of a mountain
That's common in high mountains region where the mountains are so high they block the passage of clouds to the other side.
Answer:
<u>Geocentric Model</u>: - this model is Earth Centered
-Retrograde motion is explained by epicycles
<u>Heliocentric Model</u>: - This model is Sun Centered
-Retrograde motion is explained by the orbital speeds of planets
<u>Both models</u>:- Epicycles and deferents help explain planetary motion
-Planets move in circular orbits and with uniform motion
-The brightness of a planet increases when the planet is closest to Earth
Explanation:
Retrograde motion is an apparent change in the movement of the planet through the sky. Ptolemy's model of the solar systems was geocentric, where the Sun, Moon, planets and start all orbit the Earth in perfectly circular orbits. However this perfectly circular orbits around the Earth did not explain the occasional retrograde motion of the planets. In the Copernicus' heliocentric model, retrograde motion of planets is naturally explained. The explanation for retrograde motion in a heliocentric model is that retrograde occurs roughly when a faster moving planet catches up to and passes a slower moving planet.
