Step-by-step explanation:
Not sure if it's correct.
Answer:
½
Explanation:
According to the Unit Circle, tan240° [when it falls in between 180° and 270°] is √3, so we plug this into the sine function to get this:
sin240° - 210° → sin30° >> ½

** I do not have Unit Circle video uploaded yet, but if I need to, just notify me in the comments or on of course, You-Tube.
*** Plus, we need to make sure that the x-value falls in between 0 and π\2, which it did, so no need to worry.
**** Now, 60° is the main possible answer, however, it falls in between 0° and 90°, not 180° and 270°.

Step-by-step explanation:
5³× i⁹ = 125 × i¹ = 125i
By the way :
i⁹ = (i⁴)²× i¹ = (1)²×i = i.

Answer:
Step-by-step explanation:
When we have potential expression that include imaginary numbers, we have to consider some basic results, because these imaginary potential expression are cyclical.
We know that:
So, elevating both members to a third power, we have:
So, , which is the beginning, that's why we say that it's like a cycle.
So, from the problem, we have:
To solve this, we consider the operations from the beginning:
; and
; because
Therefore, the result would be
B: (0.5)(–0.5)(3.2)(7.9)(–2.4)
C: (0.5)(–0.5)(3.2)(–7.9)(–2.4)
D: (0.5)(–0.5)(3.2)(–7.9)(–2.4)(0)
Answer:
C
Step-by-step explanation:
Rules of multiplying numbers with positive and negative signs are the following:
This means that there should be an odd number of negative numbers in a product to get a negative number.
A will be positive.
B will be positive.
C will be negative.
D will be neither since 0 is its product
The factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
The factors of 50: 1, 2, 5, 10, 25, 50
The factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100
So their common factors are; 1, 2, 5, 10
and the greatest common factor is: 10
Hope that helps! :D
