Answer:

7 + 42i.

Step-by-step explanation:

u v = 7i(6 - i)

= 42i - 7i^2 But i^2 = -1 so:

= 42i - 7(-1)

= 7 + 42i.

The forumla f = 3y yards y to feed f and f = (n/12) converts inches n to feet f. write a composition of functions that converts

Solnce55 [7]

Equating the two formulas for f, you have
n/12 = f = 3y
Then multiplying by 12 you get
n = 36y

This formula converts yards (y) to inches (n).

The function h(x) is a transformation of the square root parent function,

kondaur [170]

Answer:

A. $h(x)=\sqrt{x-3}$

Step-by-step explanation:

<h3>Step 1: Definition</h3>

The parent function of $\sqrt{x}$ is translated to the left when $h$ is positive in the transformation $\sqrt{x+h}$ .

If $h$ is negative, the graph translates towards the left with the distance equal to the value of $h$ .

<h3>Step 2: Implementation</h3>

Here the graph moved 3 units towards the right. This means that $h$ is negative and has the value of 3.

So, plugging that into the parent function for translation, the function becomes:

$h(x)=\sqrt{x-3}$
