Maths
Dear Rainy, Shape is 300 * 300 so total 90000 sq feet. Now since u know the shape, can u pl guide abt the answer. Thank u v much in advance. J

Maths
How many trees can be planted in an area of 90000 sq feet if vertically 8 feet distance and horizontally 3 feet distance is to be kept? Pl show the method of calculations.

Calculus
Write a vector equation AND parametric equations of the line through the points A(6,-1,5) and B(-2,-3,6) direction vector = [8,2,-1] a vector equation r = (6,-1,5) + t(8,2,-1) use that to write the parametrics how do i write parametrics

Calculus
using cartesian vectors ** forgot to include that.

Calculus
determine the each resultant a) 10 km/h north followed by 8 km/h west b) 25 N at 10 degrees to the horizontal and 30 N horizontally.

Calculus
three forces each of magnitude 50 N, act in eastward, westward, and northwest directions, Find the resultant force.

Calculus
determine the angle between the planes 2x + 2y + 7z = 8 and 3x - 4y + 4z = 5

Calculus / a bit of physics
explain why a scalar equation of the line exists in 2-D space, but not in 3-D space.

Calculus
determine an equation for each plane a) contains the point A(6,2,3), B(5,1,-3), and C(5,7,-2) b) parallel to 2x + 6y + 4z = 1 and contains the point P(3,2,1)
