What is the value of (tan 65° - tan 35°) / 1 + tan 65°tan 35°?<br> 0<br> 0 V3/3

goldenfox [79]

Answer:

$\frac{ \sqrt{3} }{3}$

Step-by-step explanation:

We know that tangent angle addition formula is

$\tan(a - b) = \frac{ \tan(a) - \tan(b) }{1 + \tan(a) \tan(b) }$

This is in form already. Based on the value, a is 65 and b is 35 so let just subtract that

$\tan(65 - 35) = \tan(30)$

W e know that tan 30 is

$\tan(30) = \frac{ \sin(30) }{ \cos(30) } = \frac{ \frac{1}{2} }{ \frac{ \sqrt{3} }{2} } = \frac{1}{ \sqrt{3} } = \frac{ \sqrt{3} }{3}$

Which expression is equivalent to 4x2 - 4x – 3 in factored form?

erastovalidia [21]

Answer:

(2x-3)(2x+1)

Step-by-step explanation:

4x^2 - 4x - 3

we need two numbers that give 12 when multiplied and 4 when subtracted

the numbers are 6 and 2 because 6*2=12 and 6-4=4.

4x^2 - (6-2)x -3

4x^2 -6x +2x -3

take common

2x(2x -3)+1(2x-3)

take (2x-3) as common

(2x-3)(2x*1 + 1*1)

(2x-3)(2x+1)

The answer would be C) 4,000 per year because if you add 4 to 8 its 12 add 4 to 12 its 16 then 4 to 16 is 20 then 4 to 20 equals 24
