There Must be only one "y" for each "x". For example: y= (+-)sqrt(x^2 -1) is not a function because each x will have 2 y`s
Answer:
9
Step-by-step explanation:
2^28(3^-2/2^3)^4 x 1/(3^-5 x 2^8 x 6^0)^2
2^28(3^-2/2^3)^4 x 1/(3^-5 x 2^8 x 1)^2
2^28(3^-2/2^3)^4 x 243^2/256^2
2^28 x 1/2^12 x 3^8 x 243^2/256^2
243^2 x 1 x 2^28/256^2 x 3^8 x 2^12
2^28 x 243^2/2^12 x 3^8 x 256^2
2^16 x 243^2/3^8 x 256^2
2^16 x 3^10/2^16 x 3^8
=3^2
=9
0.05 would be the tax so the answer would be $57.85 dollars
The ball hits the ground when y = 0:-
-16t^2 + 22t + 45 = 0
we need to solve this for t
t = 2 1/2 seconds
plz mark brainly
