D 44-20=22 so yea i need 20 characters so i’m still typing
The dependent variable is the number of times you have typed. This is because time is the independent (x) variable as the number of times you've typed is the dependent (y) variable.
f(5) = 0.5^(5-1)*f(1) = 0.5^4 * 120 = 7.5
The general rule for 90° counterclockwise rotation about the origin is given by:
(x,y)→(-y,x)
thus given that S has coordinates of (5,4), then rotation through 90° will map the the figure on S'(-4,5). Hence the answer is:
C](-4,5)
