Visualize pi/2 as 90° on the unit circle. this has no real component, only imaginary. same for 3pi/2, or -pi/2 as shown in this equation:
as you move around the unit circle, you'll find that 9pi/2 is the same angle as pi/2.
Thus, the rectangular coordinates are:
D because 3/4 is .75 so 7.75 divided by .75 equals 10.333333333333333
Answer:
m + 132
Step-by-step explanation:
A is 132 miles longer than B, whose length is m.
A = m + 132
MxM=M^2 (m squared)
Highest variable comes first, so it'd be m^2+5m+6
(m+2)(m+3) is your answer. That is it factored. If that equation equals 0, then m=-2 or -3
Answer:
y + 9 = - 2(x - 9)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (9, - 9) and (x₂, y₂ ) = (- 2, 13)
m = 
= 
= - 2
Using (a, b ) = (9, - 9 ) , then
y - (- 9) = - 2(x - 9) , that is
y + 9 = - 2(x - 9)
