Answer:
27 N
Step-by-step explanation:
Since force varies directly with acceleration, we can introduce a constant, k, and write 
When force is 15, acceleration is 5, so plug it into the equation and solve for k:
Now, to find force, we use a = 9 and k = 3, so
The force is 27 N
Answer:
How many friends?
Step-by-step explanation:
Pen=x
Pencil=y
y+0.15=x
y+x=0.69
y+y+0.15=0.69
2y=0.69-0.15
2y=0.54
y=0.54/2
y=0.27 pencils
y+0.15=x
0.27+0.15=x
0x=0.42 pen
150 pencils x0.27=40.5$
225 pens x 0.42=94.5$
Total 40.5$ + 94.50$=135 $
Supplier is right about a priče.
The derivative of the function is 2x+6.
At the particular point (2,6), plug in the x coordinate for x.
2(2)+6 = 10
Hope this helps :)
