A worker has a base pay of $20 per hour, gets $4 more per hour after 8 hours, and gets $5 more per hour(from base pay) after 10 hours. How much would he make in a 15 hour day?

$333

Step-by-step explanation:

From the information given, the worker would get the base pay of $20 per hour, $4 more per hour after 8 hours  which would be $24 per hour and $5 more per hour from the base pay which would be $25 per hour after 10 hours. This means that the person would receive $20 per hour for 8 hours, $24 per hour after 8 hours until 10 hours and $25 per hour after 10 hours:

Total earnings=($20*8)+($24*2)+($25*5)

Total earnings=$160+$48+$125

Total earnings=$333

According to this, the worker would make $333 in a 15 hour day.

(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.
