It's said "The value √-9 is not -3 because --------------------
So you need to prove why -3 is not the value of √-9.
As you know (-3)^2 = (-3) * (-3) = 9, ≠ -9
Answer is A.
(-3)^2 ≠ -9
Answer:
Step-by-step explanation:
Consider that by changing the the variable x with x-c represents a horizontal shift of c units. If c>0 then it is a right shift and it is a left shift otherwise. When we multiply the variable by a number d (i.e dx) we are applying an horizontal compression/stretching. If d>1 it compresses it, and if 0<d<1 it stretches it. By multipyling the variable x by a negative sign, we are reflecting with respect the x -axis. Finally when we add a number to the function, we are applying a vertical shift.
original function x.
1. (x-7): horizontal shift of 7 units to the right.
2. 1/3(x-7): Horizontal stretching by factor 1/3.
3.-1/3(x-7): Reflection with respect the x-axis
4.-1/3(x-7)+2: Vertical shift of two units up.
Answer:
0.49
Step-by-step explanation:
P(warning or ticket) = P(warning) + P(ticket) − P(warning and ticket)
0.52 = 0.03 + P(ticket) − 0
P(ticket) = 0.49
