Answer: 38090 fish

Step-by-step explanation:

Use the equation 55,000(.96)^9. Start with the initial number in this case it is 55,000 then multiply by the percentage that remains (100% - 4% = 96%) and then put it to the ninth power because that is how many years the problem is asking for.

Write the equation for (-8, -8), with a slope if three
valentina_108 [34]

Answer:

Part--1:

We know that a equation in point-slope form is represented by:

<em> y-y1=m</em>

<em />

where m is the slope of the line and  is a point through which the line passes.  

<em />

<em>               </em>

<em />

 Consider a equation in a point-slope form as:

         

This means that the slope of the line is: 5

and the line  passes through the point (1,5).

Part--2:

Now as we know that if a line has a slope as m then the perpendicular line has a slope: -1/m

Since,

Let this perpendicular line passes through (2,6)

Hence, the equation of a line in point slope form is given by:

The graph represents the atmospheric pressure in pounds per square inch as a function of altitude in mi above the sea level. Whi
Maksim231197 [3]

Let's analyze each answer:


The atmospheric pressure is lower at 15 miles above sea level than at 10 miles above sea level.  --> true

In fact, we see that the pressure at 15 miles above sea level is less than 1 pound per square inch, while the pressure at 10 miles above sea level is almost 2 pound per square inch.


As the altitude increases, the atmospheric pressure increases.  --> false

It's actually the opposite: from the graph, we see that as the altitude increases (going towards right on the graph), the pressure decreases.

The atmospheric pressure is 14 pounds per square inch at sea level.  --> true

If we take altitude=0, we see that the value of the pressure is 14 pounds per square inch.

As the altitude approaches sea level, the atmospheric pressure increases.  --> true

As the altitude approaches sea level (so, going towards left in the graph), we see that the value of the pressure increases.

The atmospheric pressure gets close to 14 pounds per square foot as the altitude continues to increase. --> false

The pressure is 14 pounds per square inch only when the altitude is 0 miles above sea level.
