She is 26 years old because you need to do 38 - 12=26!
Recall that 1 rotation is the equivalent of 360 degrees or 2pi radians.
7.5 rotations clockwise 2pi rad
------------------------------- * ---------------------------------------
1 1 rotation counterclockwise
= -47.12 radians, or -2700 degrees.
Answer:
A. y = -5x + 11
Step-by-step explanation:
The general form of the equation of a line is given as
y - y1 = m (x - x1)
where m is the slope and x1, y1 are the coordinates of a point on the line.
m = (y2 - y1)/(x2 - x1)
Given the points (1,6) and (3, -4)
m = (-4-6)/(3-1)
=-10/2
= -5
The equation of the line will be
y - 6 = -5(x -1)
y - 6 = -5x + 5
Add 6 to both side
y = -5x + 5 + 6
y = -5x + 11
Option A
Answer:
-13 + j*2
Step-by-step explanation:
The additive inverse of a complex number x = a +j*b
is a number y, such that
x + y = 0
This means that
y = -x = - a - j*b
Therefore
The additive inverse of 13 - j*2 is equal to
-(13 - j*2) = -13 +j*2
