Answer:
Please, see attached picture
Step-by-step explanation:
We can easily solve this question by using a graphing calculator or any plotting tool.
The equation is
f(x) = (1/4)*(4)^(x)
Which is an exponential function, that grows rapidly to infinity as x increases.
Answer:
<h2>The x-coordinate after the rotation is -10.</h2>
Step-by-step explanation:
A 810° rotation is equal to a 90° rotation. So, the transformation described gives the same result than rotating 90° only.
A 90° counterclockwise rotation is defined by the rule

The given coordinate is
. Using the rule, we have

Therefore, the x-coordinate after the rotation is -10.
Answer:
p=32-c (*Units in million $)
Step-by-step explanation:
Let r be the revenue realized in any given year.
-Given that c=cost and p= revenue
#We notice that the profit, cost or revenue realized in one year is independent of the prior or subsequent year.
-Therefore, the revenue function is independent of time and is expressed as:

Hence, the yearly profit for any given year is expressed as p=32-c (*Units in million $).
