Cos(11π/3)

=cos(660)

=cos(360+180+90+30)

=cos(60)

=1/2

*Use the trigonometric quadrants to figure out the answer (All, Sin, Tan, Cos). And create the 60 degree right angled triangle with an adjacent side 1 and a hypotenuse of 2.

Determine the equation of each line
katovenus [111]

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

(a)

here m = - \frac{3}{4} and c = 6, hence

y = - \frac{3}{4} x + 6 ← equation of line

(b)

here m = 6, hence

y = 6x + c ← is the partial equation

to find c substitute (2, - 6 ) into the partial equation

- 6 = 12 + c ⇒ c = - 6 - 12 = - 18

y = 6x - 18 ← equation of line

(c)

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 1, 3) and (x₂, y₂ ) = (4, 7)

m = \frac{7-3}{4+1} = \frac{4}{5}, hence

y = \frac{4}{5} x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (- 1, 3 ), then

3 = - \frac{4}{5} + c → c = 3 + \frac{4}{5} = \frac{19}{5}

y = \frac{4}{5} x + \frac{19}{5} ← equation of line

Jack is playing a game. When a player wins 3 consecutive games, the player receives 10 bonus points and then the player’s total
Paladinen [302]
<span>The function can be described as

b(p)= player receives 10 bonus points 
</span>b(p)= p+10<span>

s(p)= increases 5% of the player’s current points 
</span>s(p)= <span>p*(100%+5%)= p*1.05

then </span><span> (s ∘ b)(p) would be
