Answer:

Option (4)

Step-by-step explanation:

Domain of a relation or function is the set of input values (x-values) and Range is the set of output values (y-values).

Therefore, from the given table in the attachment,

Domain → {10, 15, 19, 32}

Range → {-1, 5, 9}

Option (4) will be the correct option.

8. Is the following statement true or false? Justify your conclusion. If a and b are nonnegative real numbers and a + b =0, then

atroni [7]

Answer:

If $a + b = 0$ then $a = 0$ and $b =0$

a | b | a + b (answer)

0 | 0 | 0

0 | 1 | 1

0 | 2 | 2

1 | 0 | 1

2 | 0 | 2

1 | 1 | 2

2 | 1 | 3

Step-by-step explanation:

Considering the following conditions for the real numbers:

$a\geq 0\\b\geq 0$

Following the rules of these in-equations, it is possible to deduce:

$a + b \geq 0$

Then, if the proposed statement is:

$a + b = 0$

The conditions above shall comply the requirements established, but first, analyzing the statement:

If $a \geq 0$ and $b \geq 0$ then $a + b \geq a$ , $a + b \geq b$ and $a + b \geq 0$ .

If $a = 0$ and b a non negative real number, then $a + b \geq b$ , but because to $a = 0$ , then $a + b = b$ . Due to the commutative property of sums, the same behavior will be presented if $b = 0$ and a a non negative real number.

According to that, if $a + b = 0$ , then $a = 0$ and $b = 0$ .

Find the radius r of the circle. Round your answer to the nearest tenth.

asambeis [7]

Answer:

1.1 yd

Step-by-step explanation:

120 × π/180 = 2π/3

2.3 = r × 2π/3

=> r = 2.3 ÷ 2π/3

=> r ≈ 1.1
