There are 8 weeks and 18 books. therefore you would multiply these numbers together.
the answer would be 144 different combinations.
not sure about the permutation or combination notation, but I got you on the first part!
Multiply each term by a^2b^2:-
b^2y^2 + a^2x^2 = a^2b^2
subtract a^2x^2 from both sides
b^2y^2 = a^2b^2 - a^2x^2
Now divide both sides by b^2
y^2 = a^2 - a^2x^2 / b^2 = a^2 (1 - x^2/b^2)
take positive square root ( because y > 0)
y = a sqrt(1 - x^2/b^2)
I think it’s A cus it’s more general info about it that sums up the difference of the chronicle to the other ones i’m not sure tho
Answer: 2/3 is the slope I think and for the same slope thing here is my answer:
We can use similarly of triangles in this case there will be a formation of 2 pairs equal ( angles formed by the y-axis on the parallel lines) angles between triangles formed as the y-axis lines are parallel. So,the slope is the same for both.
Yes I can help you with the question you have displayed
