Answer:
1.320 ,
2.322
Step-by-step explanation:
1. Given that,
a+1/a=18
now,
(a- 1/a)² =( a+1/a)² - 4a. 1/a [(a- b)² =( a+b)² - 4a. b ]
=18² - 4 . 1 [as, a . 1/a =1 ]
=324 - 4
=320
2.Given that,
a - 1/a=4
now,
a⁴+(1/a)⁴
=(a²)² + (1/a²)² [a⁴=(a²)² & (1/a)⁴=(1/a²)²]
=(a²+1/a²) ²- 2 a². (1/a²) [a²+b²=(a+b)²-2ab]
=[(a - 1/a)² +2.a. 1/a]² - 2 [a²+b²=(a-b)²+2ab]
=[4²+2]² -2
=[16+2]²-2
=18²-2
=324-2
=322
Answer:
A'(0, 1), B'(3, 1), C'(3, -1), D'(0, -1)
Step-by-step explanation:
Add (-1, 3) to each of the given points:
A' = A + (-1, 3) = (1-1, -2+3) = (0, 1) . . . . for example
I guess it could represent a situation where you have
of a cake left and you have to share it with three of your friends (in addition to yourself). So that's four people sharing
of a cake.
