If 2tanA=3tanB,then prove that tan(A-B)=sin2B/(5-cos2B) ...?
andreev551 [17]
Tan ( A - B ) = ( tan A - tan B ) / ( 1 + tan A tan B )
tan A = 3 tan B/2
tan ( A - B ) = ((3 tan B/ 2)-tan B) / ( 1 + 3 tan² B/2)=
= (tan B/2)  / ( 2 + 3 sin²B/cos²B )=
= (sin B / cos B) / (( 2cos² B+3sin²B)/cos²B)=
=( sin B cos B ) / ( 2 cos²B + 3 ( 1 - cos² B ) ) =
= (sin B cos B ) / ( 2 cos² B + 3 - 3 cos² B ) =
= ( sin 2 B ) / 2 ( 3 - cos² B ) =
= ( sin 2 B ) / ( 6 - cos² B )=
= ( sin 2 B ) / ( 5 + 1 - 2 cos² B )=
= ( sin 2 B ) / ( 5 + sin² B + cos ² B - 2 cos² B ) =
= ( sin 2 B ) / ( 5 - ( cos² B - sin² B ) ) =
= ( sin 2 B ) / ( 5 - cos 2 B )  - correct

.Write the first five terms of the sequence defined by the recursive formula
Blizzard [7]

Answer:

The first five terms are -1,2,8,20,44.

Step-by-step explanation:

The sequence is defined recursively by the formula a_n=2\times(a_{n-1})+4.


The first term of the sequence is given to be, a_1=-1.


To find the next term, we substitute n=2 in to the above formula to get,

a_2=2\times(a_{2-1})+4.


\Rightarrow a_2=2\times(a_{1})+4.


But a_1=-1


\Rightarrow a_2=2(-1)+4.


\Rightarrow a_2=-2+4.


\Rightarrow a_2=2.



To find the third term, we substitute n=3 in to the above formula to get,

a_3=2\times(a_{3-1})+4.


\Rightarrow a_3=2\times(a_{2})+4.


But a_2=2


\Rightarrow a_3=2(2)+4.


\Rightarrow a_3=4+4.


\Rightarrow a_3=8.




To find the fourth term, we substitute n=4 in to the above formula to get,

a_4=2\times(a_{4-1})+4.


\Rightarrow a_4=2\times(a_{3})+4.


But a_3=8


\Rightarrow a_4=2(8)+4.


\Rightarrow a_4=16+4.


\Rightarrow a_4=20.



To find the fifth term, we substitute n=5 in to the above formula to get,

a_5=2\times(a_{5-1})+4.


\Rightarrow a_5=2\times(a_{4})+4.


But a_4=20


\Rightarrow a_5=2(20)+4.


\Rightarrow a_5=40+4.


\Rightarrow a_5=44.



Therefore, the first five terms are -1,2,8,20,44. The correct answer is C

PLEASE HELP
lisabon 2012 [21]

Answer:

Area = 210m^2

Step-by-step explanation:

If you turn your shape sideways, you can see you have a trapezoid.

Area of a trapezoid is Average Parallel sides × height. That is:

Area

= (base+base)/2 ×h

The two measures are given for the bases, 5 and 16. The height is also given.

see image.

A = (5+16)/2 • 20

= 210

Area is 210m^2.
