For this case we have the following complex numbers:
 5 - 3i
 4 - 5i
 Multiplying both numbers we have:
 (5 - 3i) * (4 - 5i)
 (5 * 4) + (5 * (- 5i)) + ((-3i) * 4) + ((-3i) * (- 5i))
 Rewriting we have:
 20 - 25i - 12i + 15i ^ 2
 20 - 37i + 15 (-1)
 20 - 37i - 15
 5 - 37i
 Answer:
 
the product of 5 - 3i and 4 - 5i is:
 
5 - 37i

You can only add/subtract like terms so:

2a+ab+2b+4a^2-3ab+9

2a-2ab+2b+4a^2+9  (the only like terms were ab and -3ab)

deff fn [24]

Answer: a) H = h( 0.5 )^n

b) H = 1.125inches

Step-by-step explanation:

Let H = height of the ball

n = number of time the ball bounces

h = initial height.

The exponential function to model the height of the ball will be:

H = h( 1 - 0.5)^n

H = h( 0.5 )^n

It's minus because the height of the ball is decreasing.

h = 36 inches

n = 5

H = 36( 1 - 0.5 ) ^5

H = 36( 0.5 )^5

H = 36 × 0.03125

H = 1.125inches
