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

An ice cream store sells 28 flavors of ice cream. Determine the number of 4 dip sundaes.
katrin [286]

Answer:

20,475\ ways

Step-by-step explanation:

we know that

<u><em>Combinations</em></u> are a way to calculate the total outcomes of an event where order of the outcomes does not matter.

To calculate combinations, we will use the formula

C(n,r)=\frac{n!}{r!(n-r)!}

where

n represents the total number of items

r represents the number of items being chosen at a time.

In this problem

n=28\\r=4

substitute

C(28,4)=\frac{28!}{4!(28-4)!}\\\\C(28,4)=\frac{28!}{4!(24)!}

simplify

C(28,4)=\frac{(28)(27)(26)(25)(24!)}{4!(24)!}

C(28,4)=\frac{(28)(27)(26)(25)}{(4)(3)(2)(1)}

C(28,4)=20,475\ ways

Luba_88 [7]

Answer:

Juan would need to fill up the 1/4 measuring cup 24 times.

Step-by-step explanation:

So to measure one cup of flour with a 1/4 measuring cup, you would need to fill up the 1/4 measuring cup 4 times. Since we want 6 cups, you would need to fill up the 1/4 measuring cup 24 times. 6 times 4 = 24. Hope this helps!
