Apply the square root principle to solve (x – 2)2 + 20 = 0. Question 13 options: A) x = –2 + 2i√5 , x = –2 – 2i B) x = 2 + 2i√5, x = 2 – 2i C) x = –2 + 2√5, x = –2 – 2 D) x = 2 + 2√5 , x = 2 – 2

answer:

a=9

step-by-step explanation: lmk if you need a explanation

answer:   c ?

step-by-step explanation:

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
