Answer: z =2.22
Step-by-step explanation:first determine the constant. Z= K(X/Y) if z is 15, x is 6 and y is 2 then 15= K(6/2) then K is 5.
When x is 4 and y is 9 . k is 5 then
Z ,= 5(4/9) = 2.2.
Answer:
2i and -2i
Step-by-step explanation:
I'll change u to x to be easier to understand.
x^2 = -4
sqrt(x^2) = sqrt(-4)
sqrt(-4) = 2i, or -2i
Answer:10 ft
25
yes because every time x changes y changes the same amount
