The latest online craze is a new game, Khan on Seven. You get
1 answer:
Answer:
The required inequality is
Step-by-step explanation:
Consider the provided information.
You get 100 points for playing the game. In addition, you get 50 points for each seven-letter word you make with the ten letters you receive.
Let w represents a seven letter word which Sal will need to make to break the record.
She gets 100 points for playing the game and 50 points for each seven-letter
Therefore the total points earned is:
Sal wants to break the record, and she needs 18,000 points or more.
Thus, the required inequality will be:
Hence, the required inequality is

Polar and cartesian equation<h2>Initial explanation</h2>
<h2>STEP 2: secØ equation</h2>
<h2>STEP 3: comparison between given equation and secØ equation</h2>
Let's analyze the relation between r and x and y:
We have that between the indicated value of r (of the polar coordinates) and x and y (of the cartesian coordinates) there is a relation because they form a triangle. If r changes, then the value of x and y will change.
<h2>STEP 1: given equation</h2>Using the given equation
r = 2 secØ
we have that
Observing the image of the initial explanation we have a right triangle, we know that the equation of
secØ for any right triangle is given by:
In this case,
hypotenuse = r
adjacent side = x
then,
Then, we have that:
This means that:
Then,
x = 2
The equation in cartesian coordinates is x=2.
Answer: x=2
