Answer:
To find the exact vale of atan(-sqrt(3)) we're going to need the help of a calculator
atan(-sqrt(3)) = -1.04719755 rads.
If you take a look at the important angles, you will notice that the arc is minus 60 degrees which equals -1.04716755 radians.
The slope of the line
is
.
The line perpendicular to the above line has slope
Its equation is
. Since this line passes through,
,

Thus the equation of the line in slope intercept form is 
Answer:
50.77
Step-by-step explanation:
Answer:
a) 4
b) 2
Step-by-step explanation:
a) multiply the coefficients and add the exponents
(4)(1) ·
= 4
b) divide the coefficients and subtract the exponents
(14 ÷ 7) ·
= 2
-9-(-12)=-9+12=3
-9-12=-9+(-12)=-21
