Prove that sin20 sin40 sin60 sin80=3/16

xeze [42]

Sin 20° · sin 40° · sin 80° = 1/2 ( cos 20° - cos 60° ) · sin 80° =
= 1/2 ( cos 20° sin 80° - cos 60° sin 80° ) =
= 1/2 ( (sin 100° + sin 60°)/2 - 1/2 sin 80° )= ( sin 100° = sin 80° )
= 1/2 · ( 1/2 sin 60° ) = 1/4 sin 60° = √3 / 8
sin 60° = √ 3/2
√ 3 / 2 · √ 3 / 8 = 3/16 ( correct )

A line that include the point (0,2) has a slope is -1/7 what is its equation in slope-intercept form?

Kitty [74]

Answer:

y = -(1/7)x+2

Step-by-step explanation:

A slope-intercept form is y = mx + b, where m is the slope and b the y-intercept (the value of y when x=0).

We're given the slope: m = -(1/7):

y = -(1/7)x + b

We can use the given point, (0,2) in this equation and solve for b:

y = -(1/7)x + b

2 = -(1/7)*(0) + b

b = 2

The equation becomes y = -(1/7)x + 0

y = -(1/7)x+2
