a=b+10 (1)
2*(a+8)=3(b+8) (2)

==> 2*(b+10+8)=3b+24
==>2b+36=3b+24
==>b=12
==>a=12+10=22
Joe is 22 years's old

Prove this trigonometric identity<br>sin ​3x/sin x - cos 3x/cos x =2
Sveta_85 [38]

Step-by-step explanation:

LHS= sin 3x/sin x - cos 3x/cosx

Taking LCM,

<u>=</u><u>sin3xcosx- cos3xsinx</u>

sinxcosx

<u>=</u><u>sin(3x-x)</u>

sinxcosx

= <u>2sin2x</u>

2sinxcosx

=<u> </u><u>2sin2x</u><u> </u>

sin2x

=2

= RHS.

There are 1500 bees in a colony. Each month, the number of bees decreases by 12%. There are 800 flowering plants in a garden. Ea
Shkiper50 [21]
Part A:Bees:  f ( t ) = 1,500 * 0.88^tFlowering plants: g ( t ) = 800 - 25 tPart B :f ( 6 ) = 1,500 * 0.88^6 = 696.6  ≈ 697
g ( 6 ) = 800 - 25 * 6 = 800 - 150 = 650Part C :f  ( 7 ) = 1,500 * 0.88^7 = 613g ( 7 ) = 800 - 7 * 25 = 625f ( 7 ) ≈  g ( 7 )After approximately 7 months.
