Using addition formula solve tan 15​
salantis [7]

Answer:

2 - \sqrt{3}

Step-by-step explanation:

Using the addition formula for tangent

tan(A - B) = \frac{tanA-tanB}{1+tanAtanB} and the exact values

tan45° = 1 , tan60° = \sqrt{3} , then

tan15° = tan(60 - 45)°

tan(60 - 45)°

= \frac{tan60-tan45}{1+tan60tan45}

= \frac{\sqrt{3}-1 }{1+\sqrt{3} }

Rationalise the denominator by multiplying numerator/ denominator by the conjugate of the denominator.

The conjugate of 1 + \sqrt{3} is 1 - \sqrt{3}

= \frac{(\sqrt{3}-1)(1-\sqrt{3})  }{(1+\sqrt{3})(1-\sqrt{3})  } ← expand numerator/denominator using FOIL

= \frac{\sqrt{3}-3-1+\sqrt{3}  }{1-3}

= \frac{-4+2\sqrt{3} }{-2}

= \frac{-4}{-2} + \frac{2\sqrt{3} }{-2}

= 2 - \sqrt{3}

Help! Please. I don’t know what I did wrong.
Debora [2.8K]

Answer:

1320, permutation

Step-by-step explanation:

There are 12 members

Pick a president

We have 12 choices

Now there are 11 people left to pick from

now pick a vp

We have 11 choices

Now there are 10 people left to pick from

now pick a secretary

We have 10 choices

12*11*10 = 1320

This is a permutation since it matters who is president, vp and secretary

Which graph represents the linear function below?
Luba_88 [7]

Answer:

The correct option is C.

Step-by-step explanation:

The given function is

y-4=\frac{4}{3}(x-2)              ..... (1)

The point slope form of a linear function is

y-y_1=m(x-x_1)                    ..... (2)

Where, m is slope and the graph passing through the point (x_1,y_1).

From (1) and (2), we get

m=\frac{4}{3},x_1=2,y_1=4

It means the slope of the line is positive and the graph passing though the point (2,4).

Put x=0 in the given function, to find the y-intercept.

y-4=\frac{4}{3}(0-2)

y-4=\frac{-8}{3}

y=\frac{-8}{3}+4

y=\frac{-8+12}{3}

y=1.333

The y-intercept is 1.333.

Put y=0 in the given function, to find the x-intercept.

0-4=\frac{4}{3}(x-2)

-12=4x-8

-4=4x

x=-1

The x-intercept is -1.

Therefore option C is correct.
