The radius of a circular sign is 12 12 inches. Equal parts of the sign are painted red red and yellow yellow. How many square in

iragen [17]

Answer:

226.285 square

Step-by-step explanation:

Given:

The radius of a circular sign is 12 inches.

Equal parts of the sign are painted red and yellow.

Question asked:

How many square inches are painted each color?

Solution:

Here given that <u> a circular sign is divided into two equal parts </u>and one part is painted with red and other with yellow and we have to calculate the area of each color:

We will find area of semicircle of each color:

$Area\ of\ semicircle =\frac{\pi x^{2}}{2}$

$=\frac{\frac{22}{7}\times12\times12 }{2} \\ \\ =\frac{\frac{3168}{7} }{2} \\ \\ =\frac{452.57}{2} \\ \\= 226.285\ square\ inches$

Thus, 226.285 square inches are painted each color.

The function LaTeX: f\left(x\right)=-x^2+4f ( x ) = − x 2 + 4 defined on the interval LaTeX: -8\le x\le8− 8 ≤ x ≤ 8 is increasin

enyata [817]

Given:

The function is

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

It defined on the interval -8 ≤ x ≤ 8.

To find:

The intervals on which the function is increasing and the interval on which decreasing.

Step-by-step explanation:

We have,

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

Differentiate with respect to x.

$f'(x)=-(2x)+(0)$

$f'(x)=-2x$

For turning point f'(x)=0.

$-2x=0$

$x=0$

Now, 0 divides the interval -8 ≤ x ≤ 8 in two parts [-8,0] and [0,8]

For interval [-8,0], f'(x)>0, it means increasing.

For interval [0,8], f'(x)<0, it means decreasing.

Therefore, the function is increasing on the interval [-8,0] and decreasing on the interval [0,8].

1. Hannah gives clues about her 6 digit secret number:

Ulleksa [173]

1. This is a rule which helps a person identify if a number is divisible by nine.
There is no specific answer to why this is observed but I believe that is just how multiples of nine and three behave!

It is the same with the multiples of three as well!

By the way the 6 digit number could be 513315
thanks, hope that helps!!
