<em>Refer to attached</em>

The ares consists of half-circle and a triangle

<u>Radius of circle:</u>

  • 22 cm/2 = 11 cm
  • Area = 1/2*3.14*11² ≈ 190 cm²

<u>Sided of the triangle:</u>

  • Base = 22 cm, height = 16 cm
  • Area = 1/2*22*16 = 176 cm²

<u>Total area:</u>

  • 190 + 176 = 366 cm²

Given the original statement "If a number is negative, the additive inverse is positive,” which are true? Select three options.
Sergeu [11.5K]

Answer:

The three options are;

1) If p = a number is negative and q = the additive inverse is positive, the original statement is p → q

2) If p = a number is negative and q = the additive inverse is positive, the original statement the inverse of the original statement is ~p → ~q

3) If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q

Step-by-step explanation:

Given a statement if p then q, we have, p → q. The converse of the original statement is then, if q, then p while the inverse of the original statement is then if not p then not q, and the contrapositive statement is then if not q then not p

Mathematically, we have;

The given conditional statement;

If a number is negative, the additive inverse is positive which can be expressed as follows;

The conditional statement is p → q

The converse statement is q → p

The inverse statement is ~p → ~q

The contrapositive statement is ~q → ~p

Therefore, we have;

1) The conditional statement, if p = a number is negative and q = the additive inverse is positive, the original statement which is a conditional statement is therefore p → q

2) If p = a number is negative and q = the additive inverse is positive, the original statement, which is a conditional statement is p → q, the inverse of the original conditional statement is therefore, ~p → ~q

3) If q = a number is negative and p = the additive inverse is positive, the original statement, which is a conditional statement is therefore, q → p, the contrapositive of the original conditional statement  is therefore ~p → ~q.
