It's a rational number. 9 is a perfect square. What you have asked is written as -sqrt(9), which can be written as -sqrt(3*3) which is - 3. That's perfectly OK. What would not be OK is something like -sqrt(10) which is irrational because it cannot be represented as a fraction or a whole number or a repeating decimal or a decimal that terminates.

The negative square root of nine is neither rational or irrational.

The answer to this problem is 3i, which is an imaginary number. Imaginary numbers, by definition, are neither rational or irrational.

I'm gonna go with triangle B. Triangles A,C,and E all look to be somewhat congruent in that they're all equilateral. Triangle D and F look similar but Triangle b looks like its isosceles and the others aren't like that.

Find the next three term sequence 2,8,32,128
ValentinkaMS [17]

It looks like each time you want another term, you take
the last one and multiply it by 4.

2 x 4 = 8
8 x 4 = 32
32 x 4 = 128 .

So if that's the pattern, then the next three terms are ...

128 x 4 = <em>512</em>
512 x 4 = <em>2048
</em>
and<em>
</em>
2048 x 4 = <em>8192</em>

Object------------- Diameter (cm) ----- Circumference (cm)
Aliun [14]

Answer: Flying disc

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula for each object:

Circumference(C) = π x diameter

  • Coin  

Diameter = 3  

Circumference (measured) = 10  

C (calculated) = π x d = π x 3 = 9.42  

10≅9.42

  • Flying disc  

Diameter =23

Circumference (measured) = 28  

C (calculated) = π x d = π x 23 = 72.25

72.25 ≠ 28

Not accurate

  • Jar lid

Diameter =8

Circumference (measured) =25  

C (calculated) = π x d = π x 8= 25.13

25 ≠ 25.13

  • Flower pot

Diameter =15

Circumference (measured)=47

C (calculated) = π x d = π x 15 = 47.12

47 ≠47.12

Feel free to ask for more if needed or if you did not understand something.

Find two positive numbers satisfying the given requirements. the product is 192 and the sum of the first plus three times the se
Zepler [3.9K]
<h3>Given</h3>

Two positive numbers x and y such that xy = 192

<h3>Find</h3>

The values that minimize x + 3y

<h3>Solution</h3>

y = 192/x . . . . . solve for y

f(x) = x + 3y

f(x) = x + 3(192/x) . . . . . the function we want to minimize

We can find the x that minimizes of f(x) by setting the derivative of f(x) to zero.

... f'(x) = 1 - 576/x² = 0

... 576 = x² . . . . . . . . . . . . multiply by x², add 576

... √576 = x = 24 . . . . . . . take the square root

... y = 192/24 = 8 . . . . . . . find the value of y using the above equation for y

The first number is 24.

The second number is 8.
