Answer:

18.8 inches

Step-by-step explanation:

The circumference is $\displaystyle{C = 2\pi r}$ . The diameter is two times of radius which can be expressed as $\displaystyle{d = 2r}$ .

We can rewrite the equation of circumference as $\displaystyle{C = \pi d}$ <em>. </em>Thus, substitute d = 6 in:

$\displaystyle{C = 6\pi}\\\\\displaystyle{C = 18.849}$

Rounding to the nearest tenth, we will get:

$\displaystyle{C = 18.8 \ \sf \ inches}$

Hence, the circumference is 18.8 inches.

Circumference = pi x diameter
6 x pi = 18.8 to one decimal place

The perimeter of a rectangle must be less than 170170 feet. If the length is known to be 4444 feet, find the range of possible w

katrin [286]

Answer:

$w \in (0,41)$

where w is width of rectangle.

Step-by-step explanation:

We are given the following in the question:

The perimeter of a rectangle must be less than 170 feet.

Length of rectangle = 44 feet

Perimeter of rectangle =

$2\times (\text{Length + Width})$

Let w be the width of rectangle.

According to the question,

$P < 170\\2(44 + w)$

Thus, the width of triangle should be less than 41. Since w cannot take negative values, we can express value of w in interval notation as,

$w \in (0,41)$

What is the solution to he equation (y/y-4)-(4/y+4)=3^2/y^2-16

kicyunya [14]

Answer:

$y=\pm i \sqrt{7}$

Step-by-step explanation:

Given equation is $\frac{y}{\left(y-4\right)}-\frac{4}{\left(y+4\right)}=\frac{3^2}{(y^2-16)}$

Factor denominators then solve by making denominators equal

$\frac{y}{\left(y-4\right)}-\frac{4}{\left(y+4\right)}=\frac{3^2}{(y^2-16)}$

$\frac{y}{\left(y-4\right)}-\frac{4}{\left(y+4\right)}=\frac{9}{(y+4)\left(y-4\right)}$

$\frac{y\left(y+4\right)-4\left(y-4\right)}{\left(y-4\right)\left(y+4\right)}=\frac{9}{(y+4)\left(y-4\right)}$

$y\left(y+4\right)-4\left(y-4\right)=9$

$y^2+4y-4y+16=9$

$y^2=9-16$

$y^2=-7$

take squar root of both sides

$y=\pm \sqrt{-7}$

$y=\pm i \sqrt{7}$

Hence final answer is $y=\pm i \sqrt{7}$ .
