4.5+3.14159265359 is

rational because it is a terminating decimal.

irrational because it is a repeating decimal.

irrational because it is a non-terminating and non-repeating decimal.

rational because it is a non-terminating and non-repeating decimal.

 The correct option is

(C) irrational because it is a non-terminating and non-repeating decimal.

Step-by-step explanation:  We are to select the correct statement for the following number:

Rational number:  a number is said to be rational if the digits after the decimal are either terminating or repeating.

Irrational number:  a number is said to be irrational if the digits after the decimal are non-terminating and non-repeating.

Given number is

Since the digits after the decimal and neither terminating nor repeating, so the given number is IRRATIONAL.

Thus, the number is irrational because it is a non-terminating and non-repeating decimal.

Option (C) is CORRECT.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

that is the sum
