Find the requested function value.

liq [111]

<u>Given</u>:

Given that the functions $f(x)=9 x+5$ and $g(x)=-4x^2-6x+3$

We need to determine the value of the function $(f \circ g)(-9)$

First, we shall determine the value of the function $(f \circ g)(x)$

<u>The value of the function </u> $(f \circ g)(x)$ <u>:</u>

Let us determine the value of the function $(f \circ g)(x)$

Thus, we have;

$(f \circ g)(x)=f[g(x)]$

$=f(-4x^2-6x+3)$

$=9(-4x^2-6x+3)+5$

$=-36x^2-54x+27+5$

$(f \circ g)(x)=-36x^2-54x+32$

Thus, the value of the function is $(f \circ g)(x)=-36x^2-54x+32$

<u>The value of the function </u> $(f \circ g)(-9)$ <u>:</u>

The value of the function $(f \circ g)(-9)$ can be determined by substituting x = -9 in the function $(f \circ g)(x)=-36x^2-54x+32$

Thus, we have;

$(f \circ g)(-9)=-36(-9)^2-54(-9)+32$

$=-36(81)-54(-9)+32$

$=-2916+486+32$

$(f \circ g)(-9)=-2398$

Thus, the value of the function $(f \circ g)(-9)$ is -2398

Hence, Option A is the correct answer.

Paul's car will go 49 kilometers on 7 tanks. Paul wants to know how fuel efficient the car is.

Dovator [93]

49 kms : 7 tanks
divide both sides by 7
equals

Find sin X, cos X, and tan X as<br> a fraction in simplest form.

cupoosta [38]

Answer:

sin X = $\frac{4}{5}$

cos X = $\frac{3}{5}$

tan X = $1\frac{1}{3}$

Step-by-step explanation:

First, find what the hypothenuse is:

$c^{2} = a^{2} + b^{2}$

$c^{2} = 18^{2} + 24^{2}$

$c^{2} = 324 + 576$

$\sqrt{c^{2}} = \sqrt{900}$

c = 30

$sine = \frac{opposite}{hypothenuse}\\\\$

sin x = $\frac{24}{30} = \frac{4}{5}$

$cosine = \frac{adjacent}{hypothenuse}$

cos x = $\frac{18}{30} = \frac{3}{5}$

$tan = \frac{opposite}{adjacent}$

tan x = $\frac{24}{18} = 1\frac{6}{18} = 1\frac{1}{3}$
