use Euclid division lemema to show that the cube of any positive integer is of the form 9m, 9m + 1 or 9m + 8. |
|
Answer» Answer: Below is step by step Explaination Step-by-step explanation: Let us CONSIDER a and b where a be any positive NUMBER and b is equal to 3. According to Euclid’s Division Lemma a = bq + r where r is greater than or equal to zero and less than b (0 ≤ r < b) a = 3q + r so r is an integer greater than or equal to 0 and less than 3. Hence r can be either 0, 1 or 2. Case 1: When r = 0, the equation becomes a = 3q Cubing both the sides A3 = (3q)3 a3 = 27 q3 a3 = 9 (3q3) a3 = 9m where m = 3q3 Case 2: When r = 1, the equation becomes a = 3q + 1 Cubing both the sides a3 = (3q + 1)3 a3 = (3q)3 + 13 + 3 × 3q × 1(3q + 1) a3 = 27q3 + 1 + 9q × (3q + 1) a3 = 27q3 + 1 + 27q2 + 9q a3 = 27q3 + 27q2 + 9q + 1 a3 = 9 ( 3q3 + 3q2 + q) + 1 a3 = 9m + 1 Where m = ( 3q3 + 3q2 + q) Case 3: When r = 2, the equation becomes a = 3q + 2 Cubing both the sides a3 = (3q + 2)3 a3 = (3q)3 + 23 + 3 × 3q × 2 (3q + 1) a3 = 27q3 + 8 + 54q2 + 36q a3 = 27q3 + 54q2 + 36q + 8 a3 = 9 (3q3 + 6q2 + 4q) + 8 a3 = 9m + 8 Where m = (3q3 + 6q2 + 4q)therefore a can be any of the form 9m or 9m + 1 or, 9m + 8. |

Find the measure of an angle which is 34° less than its supplement.step by step plz |
|
Answer» Let the measure of the ANGLE be x o and the measure of its supplement be (x+34) o . Then, ⟹x = 180 o −(x+34) o
⟹x+x = 146 o
⟹2x = 146 o
⟹x = 146 o /2 ⟹x = 73 o
HENCE, the supplement of the given angle measures 73 o . |

There are three bags. The first bag contains 3 white balls, 2 red balls and 4 blackballs, the bag contains 2 white, 3 red and 5 black balls and the third bag contains 3 white, 4 red and 2 black balls. One bag is chosen at random and a ball is drawn. The drawn ball happens to be a red. What is the probability that the red ball drawn wastaken from (1) first bag, (2) second bag and (3) third bag? |
|
Answer» Step-by-step explanation: The event of selecting a RED ball is denoted by 'R'. The event of selecting the bag A is denoted by 'A'. The event of selecting the bag B is denoted by 'B'. Bag-A has 2 WHITE and 3 red balls Bag-B has 4 white and 5 red balls P(A)=P(B)= 2 1
,P( A R
)= 5 3
,P( B R
)= 9 5
From Bayes' theorem,we get P( R B
)= P(R) P( B R
)P(B)
= P( A R
)P(A)+P( B R
)P(B) P( B R
)P(B)
= ( 5 3
)( 2 1
)+( 9 5

) ( 9 5
