Somebody help please!!

89.04$

Step-by-step explanation:

1) First you need to find tax. 6%=6/100 so you need to multiply 6/100*84/1=84*6/100*1=504/100= 5 and 4/100. 5 is 5$ and 4/100 out of dollar is 4 cents or 0.04$ so 5$+0.04$=5.04$

2)  Just add $ 84.00 to 5.04$= 89.04$

89.04

Step-by-step explanation: since the sales tax is 6% simply multiply 84 by 1.06 not 0.06 0.06 is a sale not tax so 1.06 is the number you multiply by to get 89.04

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
