Luna makes a wish every time she passes a fountain, and tosses a few coins she has left as a linear function of wishes made. what is the rate of change in this function?

Rate of change of the function = (-3)

Step-by-step explanation:

Luna makes a wish every time when she passes a fountain and tosses few coins.

Table attached to the question shows the coins left with every wish she made.

From the given table

Wish      1    2     3    4    

Coins   25  22  19   16

Now we have to calculate the rate of change of the function.

Rate of change = (Number of coins left after wish 2 - Number of coins left after wish 1)/ (wish 2 - wish 1)

Rate of change = (22 - 25)/(2-1) = (-3)/1 = (-3)

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3
