If sin 0 = 7/25, find csc 0
kipiarov [429]

Answer:

csc(\theta)=\frac{25}{7}

Step-by-step explanation:

We know that:

sin(\theta)=\frac{7}{25}

And we want to find:

csc(\theta)

Remember that there is a trigonometric identity that relates the sin(\theta) function with the csc(\theta) function

csc(\theta)=\frac{1}{sin(\theta)}

Then if sin(\theta)=\frac{7}{25} this means that:

csc(\theta)=\frac{1}{\frac{7}{25}}

Finally:

csc(\theta)=\frac{25}{7}

A video game has the following formula: For every 1,333 in attack power, you gain 3 levels. You get one bonus star per every 38
aleksley [76]

Answer:

Rounded to a whole number, the player has 12 bonus stars.

Step-by-step explanation:

Since the video game establishes that for every 1,333 points of attack power 3 levels are gained, and that the player has a total of 0.21 million attack points, to determine the number of levels that player has it is necessary to perform the following calculation :

0.21 million = 210,000

210,000 / 1,333 x 3 = Levels

472.6 = Levels

Now, every 38 levels, the game awards a bonus star. To determine the amount of bonus stars that the player has, the following division must be made:

472.6 / 38 = X

12.43 = X

Thus, rounded to a whole number, the player has 12 bonus stars.
