6 - 1/2z = 2/3
subtract 6 from both sides
- 1/2z = -16/3
divide both sides by -1
1/2z = 16/3
rewrite
1z/2 = 16/3
multiply both sides by 2
1z = 32/3
z = 32/3 or 10 2/3
Hope this helps :)
Important notes:
3 sides 1 angle - COSINE RULE
2 sides 2 angle - SINE RULE
since, the question wants to find the length of BC. In the end we will have 3 sides and 1 angle and use cosine rule
formula of cosine rule:
a² = b² + c² - 2bc Cos A° (to find the length)
Cos A° = b² + c² - a² / 2bc ( to find the angle, if there is given three sides and have to find the angle)
So just substitute,
a² = 13² + 15² - 2(13)(15) Cos 95°
a = 20.6 or 21
Answer:
f(x + 3) = (4x + 13)/(x - 3)
Step-by-step explanation:
If f(x) = (4x + 1)/(x - 6)
then in f(x + 3)...js replace x with (x + 3)...
f(x + 3) = (4(x + 3) + 1)/(x + 3 - 6)
;f(x + 3) = (4x + 13)/(x - 3)
Answer:
a
Step-by-step explanation:
the answer is a. 6 faces 12 edges and 8 vertices
This ODE is separable; we have
Integrating both sides gives a general solution of
B is the only choice that is applicable.
