Answer:

10 inches per hour

Step-by-step explanation:

The water level was 13 inches at 1 PM. In 30 minutes (So in 1:30 PM) the water level was 18 inches, so it had increased by 5 inches in 30 minutes (Which is 10 inches in 1 hour). The rate of change is how much it has risen per time, we can also check that between 1;30 pm and 2:30 pm, which are 1 hour apart, the water level had risen from 18 inches to 28 inches, which is 10 inches in an hour.

likoan [24]
To solve this problem you must apply the proccedure shown below:
 1. You have that the hyperbola <span>has a vertex at (0,36) and a focus at (0,39).
 2. Therefore, the equation of the directrices is:

 a=36
 a^2=1296
 c=39

 y=a^2/c

 3. When you susbtitute the values of a^2 and c into </span>y=a^2/c, you obtain:
<span>
 </span>y=a^2/c
<span> y=1296/13

 4. When you simplify:

 y=432/13

 Therefore, the answer is: </span><span>y = ±432/13</span>
