The equation that represents the work done as a function of the distance is
Represent the work done with w, and the distance travelled with d.
So, the proportional equation is:
Where:
F represents the proportional constant (Force)
Given that, the force is 5;
The equation becomes
Hence, the equation that represents the work done as a function of the distance is
See attachment for the graph of the function

121+9=130 are both even squares and when added together it equals 130 I found this just by writing down a ton of numbers that are square numbers,
4,9,16,25,36,49,64,81,100,121,144 and then experimenting with different numbers, and 121+9=130 and 130=130 checks out to be true, and that's it!=)
Hope this helps!=)
Hi there! :)
<u>Answer:</u>
The good answer is the top left one, which is:
2x -1(5 - 3x) = 4x +2
2x - 5 + 3x = 4x + 2
Step-by-step explanation:
2x <u>- 1</u>(5 - 3x) = 4x + 2
The correct first step is to distribute the "-1" to the entire parentheses:
-1 × 5 = <u>-5</u>
-1 × -3x = <u>3x</u>
Once this first step is done, you are left with an equation looking like this:
2x - 5 + 3x = 4x + 2
Which is the top left answer for you!
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
Step-by-step explanation:
The required answer is the rate at which Machine A works when the two machines are combined.
Note: the rate of doing work is express as
Hence we can conclude that Machine A working rate is
and machine B working rate is
When the two machine works together, the effective working rate is
The fraction of the work that Machine B will not have complete because of Machine A help is the total work done by machine A
Hence the fraction of work done by A is expressed as
Hence the fraction of the work that Machine B will not have complete because of Machine A help is the total work done by machine A is
