Try this trick out on a friend. tell your friend to place a dime in one hand and a penny in the other hand. explain that you can determine which hand is holding the penny.
here’s how to do it:
a. ask the friend to multiply the value of the coin in his or her right hand by 4, 6, or 8 and then to multiply the value of the coin in his or her left hand by 3, 5, or 7.
b. now ask the friend to add the two results together and tell you the total.
c. if the total is even, the penny is in the right hand. if the total is odd, the penny is in the left hand.

Plzzz asap what is the inverse of f if f(x)=^3 sqrt x-5

What constants do you need to add to each of the following quadratic equations to complete the square? 2x2 - 3x = 0 x2 - 8x = 0 2x2 - 11x = 18

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
