Suppose that the functions q and r are defined as follows.<br> q (x) = x^2+6<br> r(x) = square x+9

Zigmanuir [339]

Answer:

$(r\circ q)(7)=8,\ (r\circ q)(7)=-8$

$(q\circ r)(7)=22$

Step-by-step explanation:

<u>Composite Function</u>

Given two functions q(x) and r(x), the composite function $r\circ q(x)$ is defined as

$(r\circ q)(x)=r(q(x))$

Similarily

$(q\circ r)(x)=q(r(x))$

The functions are

$q(x)=x^2+6$

$r(x)=\sqrt{x+9}$

Compute

$(r\circ q)(x)=\sqrt{x^2+6+9}=\sqrt{x^2+15}$

Evaluating for x=7

$(r\circ q)(7)=\sqrt{7^2+15}=\sqrt{64}=\pm 8$

We have two solutions

$\boxed{(r\circ q)(7)=8,\ (r\circ q)(7)=-8}$

Now compute

$(q\circ r)(x)=(\sqrt{x+9})^2+6=x+9+6=x+15$

For x=7

$(q\circ r)(7)=7+15=22$

$\boxed{(q\circ r)(7)=22}$

What is value of x? please help

bija089 [108]

Answer:

x = 27

Step-by-step explanation:

To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.

$\frac{x+8}{10}=\frac{2x-5}{14}$

To solve for x, cross multiply:

(x+8)(14) = (10)(2x-5)

14x + 112 = 20x -50

112 = 6x - 50

162 = 6x

27 = x
