Prove that if a and b are positive integers,then there exists a unique integers q and r such that a=bq+r where 0≤r<b

Vilka [71]

Step-by-step explanation:

Correct option is

0≤r<b

If r must satisfy0≤r<b

Proof,

..,a−3b,a−2b,a−b,a,a+b,a+2b,a+3b,..

clearly it is an arithmetic progression with common difference b and it extends infinitely in both directions.

Let r be the smallest non-negative term of this arithmetic progression.Then,there exists a non-negative integer q such that,

a−bq=r

=>a=bq+r

As,r is the smallest non-negative integer satisfying the result.Therefore, 0≤r≤b

Thus, we have

a=bq1+r1, 0≤r1≤b

Answer:

x = 18

Step-by-step explanation:

Add the opposite of the constant (-5), and multiply by the inverse of the coefficient of x (2/3).

$\dfrac{2}{3}x -5=7\\\\\dfrac{2}{3}x=12 \qquad\text{add 5}\\\\x=\dfrac{3}{2}\cdot 12 \qquad\text{multiply by $\dfrac{3}{2}$}\\\\ \boxed{x=18}$

Hello I Really need this answered

Answer:

α = 143.13⁰

Step-by-step explanation:

Given;

$Sin \ \alpha = \frac{3}{5} \ \ , \frac{\pi}{2}$

α is determined as follows;

⇒find the arcsine of ³/₅

$\alpha = sin^{-1}(\frac{3}{5} )\\\\\alpha = sin^{-1}(0.6)\\\\\alpha = 36.87 ^0 = 180^0 - 36.87^0 = 143.13^0$

$Thus, \frac{\pi}{2} < 143.13^0$

Therefore, the value of α that satisfies the given range value is 143.13⁰
