Your proportion should look something like this

$\frac{x}{6} = \frac{6}{4}$

After cross multiplication, you should end up with this equation

$4x=36$

After dividing 4 on both sides, you should get that x=9

<u>Given </u>that the functions $f(x)=x+4$ and $g(x)=x^{3}$

We need to determine the value of the function $(g \ {\circ} f)(-3)$

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

<u>Function </u> $(g \circ f)(x)$ <u>:</u>

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

Thus, we have;

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

$=g[x+4]$

$=(x+4)^3$

$(g \circ f)(x)=x^3+3x^2(4)+3x(4)^2+(4)^3$

$(g \circ f)(x)=x^3+12x^2+48x+64$

Thus, the function is $(g \circ f)(x)=x^3+12x^2+48x+64$

<u>Value of the function </u> $(g \ {\circ} f)(-3)$ <u>:</u>

The value of the function can be determined by substituting x = -3 in the function $(g \circ f)(x)=x^3+12x^2+48x+64$

Thus, we have;

$(g \circ f)(-3)=(-3)^3+12(-3)^2+48(-3)+64$

Simplifying the terms, we get;

$(g \circ f)(-3)=-27+12(9)+48(-3)+64$

$(g \circ f)(-3)=-27+108-144+64$

$(g \circ f)(-3)=1$

Thus, the value of the function $(g \ {\circ} f)(-3)$ is 1.

Find the exact value of csc 5pi/6

Leona [35]

Answer:

csc 2 (csc $\frac{5\pi}{6}$ = csc 150 = csc 30 = csc 2)

Step-by-step explanation:

csc $\frac{5\pi}{6}$ is in the 2nd Quadrant where only sin, and csc are positive.

csc $(\frac{5\pi}{6})=csc (\pi -(\frac{5\pi}{6}))=csc(\frac{5\pi}{6})$

but csc $\frac{5\pi}{6}$ = $\frac{1}{sin (\pi/6)} = \frac{1}{sin 30} = \frac{1}{1/2} =2$

The circle below is centered at the point (3,1) and has a radius of length 2. What is its equation?

Paul [167]

It is letter B.
Equation of a circle is in the form:
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center of the circle with radius r.
