10. a a square and a rectangle have equal areas. the rectangle is 64 cm by 81 cm. what is the perimeter of the square?
a. 72 cm
b. 144 cm
c. 288 cm
d. 5,184 cm

288 cm.

Step-by-step explanation:

Area of the  rectangle =  64 * 81 = 5184 cm^2  which is also the area of the square.

The side of the square = √5184 = 72 cm.

So the perimeter of the square  = 72 * 4

= 288 cm.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
