To win a relay race, you must swim 200 yards before your opponent swims 190 yards. you swim at a pace of 50 yards every 40 seconds. your opponent swims at a pace of 10 yards every 8.5 seconds. who wins the race?

You would win the race

Step-by-step explanation:

You would have to swim for 2 minutes and 40 seconds which is the same as 160 seconds.

The opponent would swim

Which is161.5 seconds

This means you would win

(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.
