<span>1) Find an equation of the plane. The plane that passes through the point (2, 3, 4) and contains the line x = 4t, y = 2 + t, z = 3 − t 2) Find an equation of the plane. The plane that passes through (6, 0, −3) and contains the line x = 2 − 4t, y = 1 + 5t, z = 2 + 2t 3) Find an equation of the plane. The plane that passes through the point (1, −1, 1) and contains the line with symmetric equations x = 2y = 5z 4) Find the point at which the line intersects the given plane. x = 2 − t, y = 1 + t, z = 3t; x − y + 5z = 14 5) Find the point at which the line intersects the given plane. x = 2 + 2t, y = 3t, z = 4 − 2t; x + 2y − z + 2 = 0 6) Find the point at which the line intersects the given plane. x = y − 2 = 2z; 2x − y + 2z = 2</span>
Answer:
f(-2) = 3
Step-by-step explanation:
f(x) = x² + 3x +5
f(-2)=(-2)² + 3*(-2)+5
= 4 - 6 +5
= 3
Answer:
D) 29.41 oz
Step-by-step explanation:
Maya has 15 cousins, which means she is making 15 bags.
She has 441.15 oz of candy in all. Divide 441.15 with 15:
441.15/15 = 29.41
29.41 oz is your answer, or D).

Answer:
<u>Cosine is:</u>
- cos x = adjacent leg / hypotenuse
<u>Secant is:</u>
- sec x = hypotenuse / adjacent leg
or
Both refer to the same (adjacent) angle therefore cosine is used more often than secant.
