Answer:

1 yard = 3 feet or 1 foot = 0.33333

Step-by-step explanation:

One foot is equal to 12 inches. Feet can be measured using a ruler, which is typically equal to 1 foot. One foot is approximately the length of a piece of paper. A yard is equal to 3 feet. Yards are usually measured by a yardstick, which equals 1 yard. One yard is the approximate length of a baseball bat.

A rope of length 18 feet is arranged in the shape of a sector of a circle with central angle O radians, as shown in the

creativ13 [48]

Answer:

$A(\theta)=\frac{162 \theta}{(\theta+2)^2}$

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Let

r ---> the radius of the sector

s ---> the arc length of sector

Find the radius r

we know that

$2r+s=18$

$s=r \theta$

$2r+r \theta=18$

solve for r

$r=\frac{18}{2+\theta}$

step 2

Find the value of s

$s=r \theta$

substitute the value of r

$s=\frac{18}{2+\theta}\theta$

step 3

we know that

The area of complete circle is equal to

$A=\pi r^{2}$

The complete circle subtends a central angle of 2π radians

so

using proportion find the area of the sector by a central angle of angle theta

Let

A ---> the area of sector with central angle theta

$\frac{\pi r^{2} }{2\pi}=\frac{A}{\theta} \\\\A=\frac{r^2\theta}{2}$

substitute the value of r

$A=\frac{(\frac{18}{2+\theta})^2\theta}{2}$

$A=\frac{162 \theta}{(\theta+2)^2}$

Convert to function notation

$A(\theta)=\frac{162 \theta}{(\theta+2)^2}$

What are the solutions to the equation x - 7/x = 6

bearhunter [10]

The answer is C that is X=7 and X=-1

multiple x through the given equation to get rid of a fraction. It will be

${x}^{2} - 7 = 6x$

After that bring 6X to the LHS of the equation

so that it will look like the general equation that is

${x}^{2} - 6x - 7 = 0$

Use the quadratic formula (or any other approach to find the values of x

You will arrive at

$x = 7. - 1$
