One of the rules in a public speaking contest requires contestants to speak for as close to 5 minutes (300 seconds) as possible. Contestants lose 3 points for each second they speak either
over or under 5 minutes. Which expression below can be used to determine the number of
points a contestant loses if she speaks for a seconds?

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.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

answer: i think one of the answer is $150 and $300?
