33,000 in scientific notation
1 answer:
Answer:
3.3 ×
Step-by-step explanation:
1. Move the decimal in 33,000 to the left until the number now has a value between one and ten
<em>Original number: </em>33,000.
<em>New number: </em>3.3000 (3.3)
As you can see the decimal has been moved to the left four times.
2. Now we need to plug it into the "scientific notation formula" which looks like this: ×
. 'x' will be the number we just got (3.3) and 'y' will be the number of times we moved the decimal (4).
3.3 ×

Answer:
The answer to your question is: the first option - 9/
Step-by-step explanation:
Process
cosФ = adjacent side / hypotenuse
-1/9 = adjacent side / hypotenuse
adjacent side = -1 hypotenuse = 9
c² = a² + b²
b² = c² - a²
b² = 81 - 1
b = b = opposite side
But b is negative because we are in the third quadrant.
b = -
Finally csc Ф = hypotenuse / opposite side
csc Ф = - 9 /
