For this case we have a function of the form:

Where,
A: initial amount
b: decrease rate
x: time in years
Substituting values we have:

For 2010 we have:
Answer:
an exponential decay function to model this situation is:
y = 1300 * (0.97) ^ x
The population in 2010 is:
y = 1083
Answer:
C option: 6 feet
Step-by-step explanation:
Since Yolanda wants to keep the pool in proportion to the model, the ratio of diameter to depth of model and the pool will be same.
Let the depth of pool is x feet.
Ratio of Diameter to Depth of Model = Ratio of Diameter to Depth of pool
This means the depth of pool should be 6 feet if Yolanda wants to keep the pool in proportion to the model.

Answer:
m=50w
Step-by-step explanation:
In the proportional relationship between mmm, the amount of minerals, and www, the number of workers, one constant of proportionality is the mineral cost per worker. It is the number we multiply by the number of workers to get the number of mineral
The constant of proportionality is 50 This means we can multiply , 50,the number of workers to get the amount of minerals.
Now, let's write the equation:
amount of minerals m
=minerals per worker×number of workers
=50w
One correct equation is:
m=50w
