Answer:
Step-by-step explanation:
<u>Equation of the line</u>
The slope-intercept form of a line is given by:
Being:
m = the slope of the line
b = the y-intercept
We can also use the point-slope form of the line:
Being:
(h,k) = A point that belongs to the line
Two lines of slopes m1 and m2 are perpendicular if:
We are given the line:
Whose slope is m1=-2
Thus, the perpendicular line has a slope of:
The required line contains the point (-8,1), thus the equation is:
Removing the parentheses:
Adding 1:

Answer:
-1/2
Step-by-step explanation:
lim x-> π/2 cos x /(2x-π) =
lim (x-π/2)->0 sin (π/2 - x) /2(x-π/2) =
lim (x-π/2)->0 - sin (x - π/2)/2(x-π/2) = -1/2
J. 4y + 8
4(y + 2). <—— multiply 4 by what’s in the parentheses
4 • y = 4y
4 • 2 = 8
Answer:
tan C = 5/√39
Step-by-step explanation:
tan C = opp/adj
For angle C, the opposite leg is AB, 5.
The adjacent leg is BC, √39.
tan C = 5/√39
