What is the exact value of tan 30° ? enter your answer, as a simplified fraction, in the box?
attashe74 [19]

In this question , we have to find the value of tan 30  and we need to write the answer in simplified form .

tan x = \frac{sin x}{ cos x}

Substituting the values of sin (30) and cos(30, we will get

tan (30) = \frac{1/2}{ \sqrt{3} /2}

Multiplying both numerator and denominator by 2, we will get

tan(30 )  = \frac{1}{ \sqrt3}

TO simplify it, we need to multiply both numerator and denominator by square root 3.

tan(30) = \frac{ \sqrt 3}{ \sqrt3 * \sqrt 3} = \frac{ \sqrt 3}{3}

Find the equation of the line (in slope-intercept form) through the points (1,-4) and with slope 5/2.
Phoenix [80]

Answer:

Equation of a line is y = mx + c

Where m is the slope

c is the y intercept

Equation of the line using point

( 1 , - 4) and slope 5/2 is

y + 4 =  \frac{5}{2} (x - 1) \\  \\ y + 4 =  \frac{5}{2} x -  \frac{5}{2}  \\  \\ y =  \frac{5}{2} x -  \frac{5}{2}  - 4 \\  \\  \\ y =  \frac{5}{2} x -  \frac{13}{2}

Hope this helps you
