Answer:
the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)
Step-by-step explanation:
To find the points at which a graphic crosses the x-axis we need to find the values for x where y = 0.
Therefore, in the equation x²- xy + y² = 3 we are going to make y = 0 and solve for x
x² - xy + y² = 3
x²- x(0) + (0)² = 3
x² = 3
x = ±√3
x₁ = 1.73 and x₂ = -1.73
Therefore, the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)
Answer:
9 x 10^12
Step-by-step explanation:
for multiplying scientific notation, you multiply the numbers (3 x 3) and add the exponents together (6 + 6) to get 9 x 10^12
Answer:
x = 25
Step-by-step explanation:
Answer: 70°
<u>Step-by-step explanation:</u>
ΔVWX ≅ ΔNOP ⇒ ∠V=∠N, ∠W=∠O, and ∠X=∠P
Since ∠V=44° and ∠P=66°=∠X
then we can use the Triangle Sum Theorem:
∠V + ∠W + ∠X = 180°
44° + ∠W + 66° = 180°
∠W + 110° = 180°
∠W = 70°
C should be your answer:))))
