Answer:
b = -1/10.
Step-by-step explanation:
(2i/2+i)-(3i/3+i)
= 2i(3 + i) - 3i(2 + i) / (2 + i)(3 + i)
= 6i + 2i^2 - 6i - 3i^2 / (2 + i)(3 + i)
= (-2 + 3) / (6 + 5i - 1)
= 1 / (5 + 5i)
Now we multiply top and bottom by 5 - 5i :
= 5 - 5i / (5 + 5i)(5 - 5i)
= 5 - 5i / 25 -25i^2
= 5 - 5i / 50
= 1/10 - 1/10i
Set the argument (x+1) equal to zero.
D) 1\9 because it has zero X
B) 5
A) the difference is that 1/9 has zero X and 4\9 and 5\9 have the highest which is 4
B) 4
Pretty sure it’s d(all of the above)
Answer:
The first one
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan30° = 
= 
= 
Multiply both sides by 8
8 × tan30° = b, that is
b = 8tan30°
