Answer:
The function is
Step-by-step explanation:
From the question we are told that
The rate of growth is
The total profit is $25,000
The time taken to make the profit is
From the question
is the rate of growth
Now here x represent the time taken
Now the total profit is mathematically represented as
So using substitution method
We have that
So
recall and let
At x = 2 years
$25,000
So
Since the profit rate is in million
$25,000 = $0.025 millon dollars
So
=>
So the profit function becomes

Explanation:
Part (a)
Lines LN and PN have the point N in common. This is the intersection point.
-----------------
Part (b)
To name a plane, pick any three non-collinear points that are inside it. We cannot pick points H, J, K together because infinitely many planes pass through it. Imagine the piece of flat paper able to rotate around this axis (like a propeller). Having the points not all on the same line guarantees we form exactly one unique plane.
I'll pick the non-collinear points P, H and J to get the name Plane PHJ. Other answers are possible.
------------------
Part (c)
Points H, J and K are collinear as they are on the same line. Pick either H or K to fill out the answer box. I'll go with point K
------------------
Part (d)
Point P and line HK are coplanar. They exist in the same flat plane, or on the same sheet of flat paper together.
We can think of that flat plane as the ground level while something like point N is underground somewhere. So point N and anything on that ground plane wouldn't be coplanar.
Note: there are other possible names for line HK such as line JH or line JK. The order doesn't matter when it comes to naming lines.
Answer:
x= 8
Step-by-step explanation:
17x + 3 = 139
17x = 136
x = 8
