Ok,so you can represent the students as K and Y as the cookies eaten.X is your constant of proportionality (the number you multiply to k to get y).

For the first one,14/2 which equals 7.Try the next set,21/3=7 also and finally 35/5=7.You can see that the C.O.P is 7.

Answer: f(0)= -4, f(5)= 15, f(-3)= -7

Step-by-step explanation:

0 < 1, so plug into x-4. 0-4=-4

5> 1, so plug into 3(x). 3*5=15

-3<1, so plug into x-4. -3-4=-3+(-4)= -7

Answer: (a) Magnetic flux before rotation is 7.2 × 10^-8 Wb and magnetic flux after rotation is 0

(b) The average emf induced in the coil is 3.6×10^-4 V

Step-by-step explanation:

Here is the complete question:

In a physics laboratory experiment, a coil with 200 turns en-closing an area of 12 cm2 is rotated in 0.040 s from a position where its plane is perpendicular to the earth’s magnetic field to a position where its plane is parallel to the field. The earth’s magnetic field at the lab location is 6.0×10^−5T. (a) What is the total magnetic flux through the coil before it is rotated? After it is rotated? (b) What is the average emf induced in the coil?
