Answer:

1)10

2)10

3) 7

Step-by-step explanation:

Modulus means we always take the positive value for example

|-3| = +3

1) Find the absolute value of |8 + y| when y = 2

$|8+2| \\|10|\\10$

2) Find the absolute value of |-8 + y| when y = -2

$|-8+(-2)|\\|-8-2|\\|-10|\\10$

3) Simplify 4 + |x + 2| when x = -5

$4 + |x + 2|\\4+|-5+2|\\4+|-3|\\4+3\\7$

(TCO 3) How many different teams can be organized consisting of two men, two women, and two children? We have the following grou

Nady [450]

Answer:

900 teams

Step-by-step explanation:

The order in which the people are selected is not important(John and Josh is the same team as Josh and John), which means that the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

Two men(from a set of 6).

Two women(from a set of 5).

Two children(from a set of 4).

How many different teams can be organized consisting of two men, two women, and two children?

$T = C_{6,2}*C_{5,2}*C_{4,2} = \frac{6!}{2!4!}*\frac{5!}{2!3!}*\frac{4!}{2!2!} = 15*10*6 = 900$

(02.06) Simplify 10/8-5i.

musickatia [10]

Multiply both numerator and denominator with 8+5i. Then you get $\frac{10(8+5i)}{8 ^{2} +5^{2} } = \frac{80+50i}{89} = \frac{80}{89}+ \frac{50}{89} i$
