Answer:
See below ~
Step-by-step explanation:
Identities :
- cot x = cos x / sin x
- sin²x + cos²x = 1
Changing the Left Hand Side (LHS) :
- 1/cot x + cotx
- 1/(cos x / sin x) + cos x / sin x
- sin x / cos x + cos x / sin x
- Take (sin x)(cos x) as the LCM (Least Common Multiple)
- sin x (sin x) + cos x (cos x) / (sin x) (cos x)
- sin²x + cos²x / cos x sin x
- 1/cos x sin x
- Equal to the RHS
Answer:
1/4
Step-by-step explanation:
this is the answer hope will help
4 sqrt 3 is your answer (b)
Answer:
see below
Step-by-step explanation:
z = 9 + 3i
This is in the form a+bi where a is the real part and b is the imaginary part
1.The real part is 9
2. The imaginary part is 3
The complex conjugate is a-bi
3. complex conjugate 9-3i
4. 3i - z = 3i - (9+3i) = 3i -9 - 3i = -9
5. z-9 = 9+3i - 9 = 3i
6. 9-z = 9- (9+3i) = 9-9-3i = -3i
Answer:
$18.95
Step-by-step explanation:
if you divide $11.37 by 3, you find the price for 1 pound of cherries which would look like this: 11.37 / 3 = 3.79
then you would add the price of two additional pounds of cherries to the original 3 pounds which would look like this: 11.37 + 3.79(2) = $18.95
i hope this helps :)
