Csc²x - 1
1/sin²x - 1
1/sin²x - sin²x / sin²x
(1 - sin²x) / sin²x
Recall that sin²x + cos²x = 1
So cos²x = 1 - sin²x
So we can replace numerator to cos²x
cos²x / sin²x
= cot²x
Final answer: cot²x
There are 8 big fish for every 10 small fish, ..... 5 small fish.
The answer is 4
Because 0.5 times 4 is 2
Answer:
No Problem, I know That I personally can't stand it when people just give me the number. So another way to think of this problem is "How many 2/3 are in 3 cups." So try drawing 3 rectangles to represent 3 cups and then draw two lines inside those rectangles so that there are 3 rectangles inside each one and then shade in two of the smaller rectangles in a way that you can tell them all apart preferably different colors and then just count them.

Answer:
Step-by-step explanation:
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 5,820
New Number: 5.820
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 5 . 8 2 0
Decimal Count: 1 2 3
There are 3 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 5.82 (Please notice any zeroes on the end have been removed)
b = 3
Now the whole thing:
5.82 x 103
Step 4
Check your work:
103 = 1,000 x 5.82 = 5,820
