The radius of a square is 16 cm what is the area

2 answers:

6 0

Radius is normally used for a circle
in a circle, radius is the distance form the center of the circle to the outer edge of the circle
area=legnth times width or in square area=legnth times legneth
since this is a square and this is a math problem, we will assume that radius=1/2legnth so
if radius=16 then legnth =2 times 16=32
area=32 times 32=1042

area=1042 square cm or 1042 cm^2

Answer:

2. Eunju is right

3. $x^2+5x+6$ is a factor of $x^4+5x^3+2x^2-20x-24$ .

Step-by-step explanation:

<u>Polynomial Remainder Theorem</u>

The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).

As a consequence, if a polynomial is divisible by x-a, f(a)=0.

Part 1:

Let's make:

$f(x)=(x+b)^3+(x+c)^2-(b-c)$

To find out if x+b is a factor of f(x), we find f(-b):

$f(-b)=(-b+b)^3+(-b+c)^2-(b-c)$

Operating:

$f(-b)=(-b+c)^2-(b-c)$

The value of f(-b) is not zero. This means Eunju is right, x+b is not a factor of f(x).

Part 2:

We must find out if $x^2+5x+6$ is a factor of $x^4+5x^3+2x^2-20x-24$ without using long division or synthetic division.

We can use the polynomial remainder theorem again, but since the factor is not in the form (x-a), we can factor it as follows:

$x^2+5x+6 =(x+2)(x+3)$

Now we just apply the theorem twice. If both remainders are zero, then the assumption is true.

Let's make:

$f(x)=x^4+5x^3+2x^2-20x-24$

Find f(-2):

$f(-2)=(-2)^4+5(-2)^3+2(-2)^2-20(-2)-24$

$f(-2)=16-5*8+2*4+40-24 =16-40+8+40-24=0$

Find f(-3):

$f(-3)=(-3)^4+5(-3)^3+2(-3)^2-20(-3)-24$

$f(-3)=81-5*27+2*9+60-24$

$f(-3)=81-135+18+60-24 =0$

Since both f(-2) and f(-3) are zero, $x^2+5x+6$ is a factor of $x^4+5x^3+2x^2-20x-24$ .

What is the reliability of a two-component product if the components are in parallel, with individual reliabilities of 0.95, and

user100 [1]

The reliability of a two-component product if the components are in parallel is 0.99.

In this question,

The probability of failure-free operation of a system with several parallel elements is always higher than that of the best element in the system. Reliability can be increased if the same function is done by two or more elements arranged in parallel.

A system contains two components that are arranged in parallel, they are 0.95 and 0.80.

Therefore the system reliability can be calculated as follows

⇒ 1 - ( 1 - 0.95 ) × ( 1 - 0.80 )

⇒ 1 - (0.05 × 0.20)

⇒ 1 - 0.01

⇒ 0.99

Hence we can conclude that the reliability of a two-component product if the components are in parallel is 0.99.
