Answer:

Difference = 2.25°

Step-by-step explanation:

Here we are given that at depth the Temperature T is inversely proportional to the depth x.

$T$ ∝ $\frac{1}{x}$

$T= 4500 \times \frac{1}{x}$

Where 4500 is constant

Now we have to find the difference in the temperature at 1200 mts and 3750 mts

1. x=1200

$T= 4500 \times \frac{1}{x}$

$T= 4500 \times \frac{1}{1200}$

$T= 3.75$

2. x=3750

$T= 4500 \times \frac{1}{x}$

$T= 4500 \times \frac{1}{3750}$

$T=1.2$

Hence Difference is

T = 3.75 -1.20

= 2.25

Therefore The difference of the temperature at 1200 mts and 3750 mts is T=2.25°

In 1985, there was 285 cell phones subscribers in the small town of centerville.After 1985, the number of subscribers increased

wolverine [178]

First we write a function that suits the problem.
We have then:
y = 285 * (1.75) ^ x
Then, we see how many years there are in the requested period
x = 1994-1985 = 9
We evaluate the function for x = 9
y = 285 * (1.75) ^ 9
y = 43871.98637
Round nearest whole number
y = 43872
Answer:
there were 43872 cell phones subscribers in centerville in 1994
