the correct answer would be:
A) (x, y) → ( x + 1, y + 2); (−2, 6)
Answer:
what do you mean by x?
Step-by-step explanation:
This will be:
[√9]/[(3-2i)+(1+5i)]
simplifying the above we get:
√9/(3+1-2i+5i)
=√9/(4+3i)
rationalizing the denominator we get:
√9/(4-3i)×(4-3i)/(4-3i)
=[√9(4-3i)]/(16+9)
=[3(4-3i)]/25
=(12-9i)/25
Answer: (12-9i)/25
37 is 25% of 148; 148 is 400% of 37
Step-by-step explanation:
Let us solve the questions one by one
"37 is ____ % of 148"
Let x be the percentage
Then
to convert in percentage, multiplying by 100
= 25%
"148 is ____ % of 37"
Let y be the percentage
then
To convert into percentage, multiplying by 100
= 400%
Hence,
37 is 25% of 148; 148 is 400% of 37
