I need help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Zina [86]

Answer:

Yes, x and y have a proportional relationship.  

Step-by-step explanation:

A proportional relationship means that, when comparing two quanities, that they are both changing at a constant (same) amount.  When looking at a table to compare quantities, you can see that the pounds of tomatoes 'x' is increasing by one (1) each time.  If you look at the amount spent in dollars 'y', you can see that for each pound (x), the cost is increasing by $4.  So, since for every pound of tomatoes that is purchased increases by $4, then their relationship is proportional.

PLEASE HELP ME 40 POINTS
Serjik [45]

Answer:

see below

Step-by-step explanation:

A: radius of 12 ft

    Changing to meter

 12 ft * .305 m/ ft =3.66 meter

The radius is 3.66 meters

The diameter is twice the radius = 2*3.66 =7.32 meters

The circumference is

C = pi*d = 3.14 * 7.32 =22.9848 = 22.98 meters

B diameter is 7.5 meters

Pool B has a bigger diameter

C = pi * d = 3.14 * 7.5m = 23.55 meters

The difference is .57 meters

Does this graph represent a function ? Why or why not ?
balu736 [363]

Answer:

D) It passes the horizontal line test

Step-by-step explanation:

In order for a line to represent a function it must pass the vertical line test.

To apply the horizontal line test, take a pencil and hold it vertically. Then, move it across the graph from left to right. If it intersects the line at 1 point everywhere along the line, then it is a function (functions can only have 1 Y value for every X value).
