Answer:
( cos40° + isin40°)
Step-by-step explanation:
To divide
= 
[ cos(x₁ - x₂) + isin(x₁ - x₂)
Given
= 
( cos(90 - 50)° + isin(90 - 50)°
= ( cos40° + isin40° )
I believe it is A and D. All you have to do is add them all together and if both sides are the same then its a correct answer.
Hello from MrBillDoesMath!
Answer:
See Discussion section below
Discussion:
2x^2 + 5x + 3 = (2x+3)(x+1) which is Choice 3
3x^2+10x+4 =-1/3 (-3 x + sqrt(13) - 5) (3 x + sqrt(13) + 5)
I don't think any of the provided choices are right!
8x^2+10x-3 = (2x+3)(4x-1) which is Choice 2
6x^2-7x-4 = -1/24 (-12 x + sqrt(145) + 7) (12 x + sqrt(145) - 7)
I don't think any of the provided choices are right!
2x^2+x-28 = (2x-7)(x+4) which is Choice 2
Thank you,
MrB
Answer:
Mason is incorrect.
Step-by-step explanation:
Equivalent ratios are formed when the same number is MULTIPLIED to each number in the ratior, not when the same number is added. So for example, a ratio equivalent to 2:3 would be 4:6, because 2*2=4 and 3*2=6. You multiply to create equivalent ratios, not add.
(That would be your explanation)
