1) A couple is expecting the birth of a baby boy. They will name the child by choosing a first name

Answer:

C. 30

Step-by-step explanation:

We have a list of names that need to be sorted in a specific order. For this, we will use a permutation. This can be found on a scientific calculator, however, I'll be using the equation.

$_nP_r=\frac{n!}{(n-r)!}$

n = total number of objects

r = number of objects selected

In this instance, n will equal 6 since we have 6 different names to choose from and r will equal 2 since we are picking two names. Enter the values into the equation and evaluate.

$_6P_2=\frac{6!}{(6-2)!}=30$

Therefore, there are 30 possible two-part names.

On top of a hill, a rocket is launched from a distance 80 feet above a lake. The rocket will fall into the lake after its engine

I believe its 144ft. Since
