Simplify tan9x-tan5x / 1+tan9xtan5x​

Mathematics
1 answer:
Wittaler [7]3 years ago
5 0

Answer:

The given expressions simplifies to tan (4x).

Step-by-step explanation:

Here, the given expression is : \frac{tan9x - tan5x}{1+ tan9xtan5x}

By TRIGONOMETRIC IDENTITY:

tan (A-B)  = \frac{tanA - tanB}{1+ tanAtanB}

Putting this identity here, and taking A = 9 x, B = 5 x, we get

\frac{tan9x - tan5x}{1+ tan9xtan5x} = tan (9x-5x)

= tan(4x)

Hence, the given expressions simplifies to tan (4x).

1 hour = 14.10
5 hours = 14.10 x 5 = $70.50

Which term does not belong with the other three
AnnyKZ [126]

It seems that you have missed few parts of the question.

I searched that question on internet and got the complete question as follows:

Which term does not belong with the other three: lines, segments, planes, and rays?

Answer:

Line, segments and rays all are 1-dimensional quantity like they move in just one direction. While plane is a 2-dimensional quantity like it has length and breadth.

In that case term "plane" doesn't belong with the other three.


Hence final answer is "plane".

PLEASE HELP

Answer:

Rosaria purchased 50 bracelets and 70 necklaces

Step-by-step explanation:

Let the number of bracelets be b and the number of necklaces be n

b + n = 120 •••••(i)

Secondly;

10b + 11n = 1270 ••••(ii)

Total cost of b bracelets at 10 per 1 is 10b

Total cost of n bracelets at 11 per 1 is 11n

Adding both gives 1270

From i, b = 120-n

Substitute this into ii

10(120-n) + 11n = 1270

1200 - 10n + 11n = 1270

n = 1270-1200

n = 70

b = 120-n

b = 120-70

b = 50

Which institution informs individuals and businesses about their rights and responsibilities?
Mama L [17]

Answer:

A. The Federal Trade Commission

Step-by-step explanation:

The FTC inaugurated its doors in March 1915. The FTC's purpose is to protect consumers and encourage contestants. The FTC cannot solve individual grievances, but it can present knowledge about what steps to exercise. The FTC states that accusations can improve it and its law implementation partners identify patterns of fraud and exploitation, which may direct to examinations and preventing unfair marketing practices.
