Which is smaller-21/35, 7/5​
Paladinen [302]

Answer:

-21/35

Step-by-step explanation:

So, 7/5 is a postive number, since it doesn't have a negative - sign in front of it. On the other hand, -21/35 does. Knowing this, we can conclude that -21/35 is smaller than 7/5.

If you want another way of thinking about it, just guessing, what is 7/5? Well, 7 is bigger than 5, so it must be at least 1. On the other hand, with -21/35, the -21 doesnt look like its bigger than 35, so it must be smaller than 1.

Answer:

<u>-21/35 is smaller than 7/5 </u>

The cost of manufacturing x refrigerators is given by the function f(x)=2x^2+6000. If the cost doubles fr the year 2011 owing to
Alecsey [184]

Answer:  Vertical Stretch

Step-by-step explanation:

Given: The cost of manufacturing x refrigerators is given by the function :f(x)=2x^2+6000

If the cost doubles fr the year 2011 owing to higher raw material prices, then we multiply the given function by 2, then we get a new function :

g(x)=2(2x^2+6000)=4x^2+12000 which represents a vertical stretch in the graph.

∵ 2 is a positive constant  greater than 1 which is multiplied to the parent function f(x). So by the definition of vertical stretch the parent function will be vertically stretched .
