Answer:
We can examine each answer choice individually:
A. 569 × 10² = 569 × (10 · 10) = 569 · 100 = 56,900. Therefore, this choice is incorrect.
B. 569 · 10 = 5,690. This choice is incorrect.
C. 10³ · 569 = (10 · 10 · 10) ·569 = 1000 · 569 = 569,000. This choice is correct.
D. 10² · 569 = (10 · 10) · 569 = 56,900. This choice is incorrect.
Therefore, the correct option is C.
Answer:
3rd option
Step-by-step explanation:
Using the identities
cot x =
csc² x = 1 + cot² x
Given
tanθ = , then cotθ =
csc²θ = 1 + ( )² = 1 +
=
cscθ = ± = ±
Since θ is in 3rd quadrant, then cscθ < 0
cscθ = - ×
= -
