Answer:
This is the answer , P = 1 + (1/10)x
Step-by-step explanation:
We have,
At sea level pressure is 1 Atmosphere (i.e at x =0, P0=1 atmosphere)
At depth 23 meters , pressure = 3.3 Atmosphere
Since the pressure increases at constant rate as the depth increases, So we can write a relation as:
P =P0 + kx , where P is the pressure , P0 is the initial pressure, x is the depth and k is constant rate of increasing.
To find constant rate k, Plug P = 3.3 , P0 = 1 and x= 23 meters
We get,
3.3 = 1 + k * 23
k = 2.3 / 23 = 1/10
So we can write the function formula as: P = 1 + (1/10)x
Population are always modeled by exponential growth equation given by:
f(x)=a(1+b)^t
where:
a=original number
b=rate of growth
t=time
thus
f(x)=412(1.05)^t
the population after 9 months will be:
f(9)=412(1.05)^9=639.15=639
Answer:
there are 10 numbers so it would be 10% but there are 2 ones so 20%
