Answer:
1 - True
2 - False
3 - False
4 - True
Step-by-step explanation:
N/A
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)
Answer:
you can try adding the adding angles up to 180
or if its graphed you can count the units
Step-by-step explanation:
and know that all four sides are congruent and diagonals are perpendicular
