Clark used the order of operations to find the unknown number in 15-12÷3=n what is the value of the unknown number?
lukranit [14]
The order of operations is:

Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction

So division comes first:

\sf 15-12\div 3=n

\sf 15-4=n

Now subtraction:

\boxed{\sf n=11}

How do you do these problems?
Angelina_Jolie [31]

Answer:

18e⁶

⁵/₁₂₈

Step-by-step explanation:

Rₙ(x) = f⁽ⁿ⁺¹⁾(c) / (n+1)! (x − a)ⁿ⁺¹, and a < c < x.

f(x) = eˣ, a = 0, and n = 1.  Thus R₁ is:

R₁(x) = f"(z)/2! x²

R₁(x) = eᶻ/2 x²

|R₁| is a maximum when |f"(z)| is a maximum.  On the domain 0 < z < 6, that maximum is e⁶.  At x = 6, the upper bound of |R₁| is:

|R₁| = 18e⁶

This time, f(x) = 1 / √(1 + x) = (1 + x)^-½.  a = 0, and n = 2.

R₂(x) = f⁽³⁾(z)/3! x³

Find f⁽³⁾(x):

f'(x) = -½ (1 + x)^-³/₂

f"(x) = ¾ (1 + x)^-⁵/₂

f⁽³⁾(x) = -¹⁵/₈ (1 + x)^-⁷/₂

On the domain -½ < z < 0, |f⁽³⁾(z)| is a maximum at z = 0.

|f⁽³⁾(z)| = ¹⁵/₈

Therefore, at x = -½, the upper bound of R₂ is:

|R₂| = (¹⁵/₈)/6 |(-½)³|

|R₂| = ⁵/₁₂₈

Show that the number 6 is a rational number by finding a ratio of two integers equal to the number
svlad2 [7]

9514 1404 393

Answer:

  6 = 6/1 = 12/2 = 18/3

Step-by-step explanation:

The simplest ratio of integers with a value of 6 is ...

  6 = 6/1

We can multiply numerator and denominator by any non-zero integer value to obtain an equivalent:

  6 = 12/2 = 18/3 = -54/-9

(0,2) (4.5,0) distance formula
miskamm [114]

The distance between them = 4.93

Step-by-step explanation:

The distance between two points (x1, y1) amd (x2, y2) is \sqrt{(y2-y1)^{2}+(x2-x1)^{2}  }

Now putting the values of (0,2) and (4.5, 0) we get,

\sqrt{(0-2)^{2}+(4.5-0)^{2}  }

= \sqrt{24.25} = 4.93 (approx)
