Will mark brainliest for having the steps.<br> prove tan(2x) = tan(x+x)
jonny [76]
So here is how we are going to prove that (2(tan x - cot x) / (tan^2 x - cot^2 x} = sin (2x). Follow it step by step:
LS = 2(tanx−cotx)
------------------
tan^2−cot^2x
= 2(tanx−cotx)
----------------------
(tanx−cotx)(tanx+cotx)
= 2
-------------------
(tanx+cotx)
= 2
-----------------
Sin2x+cos2x
---------------- sinxcosx
= 2
-------------
1
------------
sinxcosx
= 2sinxcosx
= sin2x
I hope that is the answer that you are looking for. Let me know if you need more help next time. Thanks for posting your question here in brainly!

Simplify 5/8x -2y +3/4x-8y
AleksandrR [38]

Answer:

On simplification,  \frac{5}{8}x - 2y + \frac{3}{4}x -8y   =   (\frac{11}{8}) x - 10y

Step-by-step explanation:

Here, the given expression is:

\frac{5}{8}x - 2y + \frac{3}{4}x -8y

Now, we can perform operations only on LIKE TERMS,

So, in this expression, separate the like terms we get:

\frac{5}{8}x - 2y + \frac{3}{4}x -8y  =  \frac{5}{8}x +  \frac{3}{4}x - 2y -8y\\= (\frac{5}{8} +  \frac{3}{4})x -(2y + 8y)  = (\frac{5 + 3(2)}{8}) x - (10y)\\= (\frac{11}{8}) x - 10y\\\implies  \frac{5}{8}x - 2y + \frac{3}{4}x -8y   =   (\frac{11}{8}) x - 10y

Hence, on simplification,  \frac{5}{8}x - 2y + \frac{3}{4}x -8y   =   (\frac{11}{8}) x - 10y

A 12,000-lb killer whale might eat as much as 14,000 lb of fish per month (assume a 30-day month). If the average weight of a ce
brilliants [131]

Answer:

2196 fish

Step-by-step explanation:

Weight of fish that the killer whale might eat in a month (30 days) = 14,000 lb

Weight of the fish that killer whale might eat in a day = \frac{14000}{30} = \frac{1400}{3} lb.

Average weight of the fish that killer whale eats = 3.4 oz

Since,

1 pound(lb) = 16 ounces(oz)

So,

Weight of the fish that killer whale might eat in a day in ounces(oz) = \frac{1400}{3} \times 16=\frac{22400}{3} oz

Since, a certain fish weighs 3.4 oz, in order to find the number of fish that killer whale must eat, we must divide the total weight in ounces by 3.4 ounces.

So, the number of fish that killer whale would eat = \frac{22400}{3} \div 3.4 = 2196 fish

Thus, the killer whale needs to eat 2196 fish.
