Find Sin 2 (30degrees)

Vinvika [58]

Answer:

Sin 2 (30)°= $\frac{\sqrt{3} }{2}$

Step-by-step explanation:

Explanation:-

Given that Sin 2 (30)°

we know that the formula sin2θ = 2sinθ cosθ

Given that θ = 30°

Now

sin2(30)° = 2sin30° cos30°

$= 2 ( \frac{1}{2} X \frac{\sqrt{3} }{2} )$

After cancellation, we get

Sin 2 (30)° = $\frac{\sqrt{3} }{2}$

Final answer:-

Sin 2 (30)° = $\frac{\sqrt{3} }{2}$

If a=5x^2+3x-7 and b=-3x^2-7x+5 find b-a

uranmaximum [27]

Answer:

-8x^2-10x+12

Step-by-step explanation:

first set up the problem:

(-3x^2-7x+5)-(5x^2+3x-7)

Since you are subtracting you need to distribute the (-) sign:

(-3x^2‐7x+5)(-5x^2-3x+7)

Now just combine like terms

-3x^2+(-5x^2= -8x^2

(-7x+(-3x= -10x

5+7= 12

set answer in standard form:

-8x^2-10x+12
