Answer:

\frac{2(a+4b)}{a^2 -b^2 }

Step-by-step explanation:

\frac{3}{a-b} -\frac{1}{a+b} +\frac{4b}{(a-b)(a+b)} =

\frac{3(a+b)}{(a-b)(a+b)} -\frac{a-b}{(a-b)(a+b)} +\frac{4b}{(a-b)(a+b)} =

\frac{3a + 3b -a + b + 4b}{(a-b)(a+b)} =

\frac{2(a+4b)}{a^2 -b^2 }

Find the sine and cosine of a 60° angle<br><br> find the sine and cosine of a 30° angle
Ymorist [56]

Answer:

Using the 30-60-90 triangle to find sine and cosine

sin(60 degrees) = 2√3 4.

sin(60 degrees) = √3 2.

sin(30 degrees) = 2 4.

sin(30 degrees) = 1 2.

cos(60 degrees) = 2 4.

cos(60 degrees) = 1 2.

cos(30 degrees) = 2√3 4.

cos(30 degrees) = √3 2.

vovangra [49]

Answer:

The answer is "NOT"

Step-by-step explanation:

  • To demonstrate a similar statement we want to have yet another side or some other angle, however, the third section is not proportional.  
  • Its sides were equivalent in proportions (yeah sure they are) + corner by the by is not given.
  • There is no triangle angle provided so, that we can not enforce the SAS argument.  
  • It is not evidence of similarity between ABC ≈DEF.

Part a which projectile spends more time in the air, the one fired from 30∘ or the one fired from 60∘? which projectile spends m
bearhunter [10]
The correct answer is the One fired from from 60° . This is because the projectile fired from 60° has a greater vertical velocity compared to the one fired from 30° and therefore spends more time on air. Vertical velocity is the velocity of a body as it moves upwards, it is normally affected by the gravitational acceleration, however it is not affected by the horizontal velocity.
