Answer:
12,500 square millimeters
Step-by-step explanation:
Direction vector of line of intersection of two planes is the cross product of the normal vectors of the planes, namely
p1: x+y+z=2
p2: x+7y+7z=2
and the corresponding normal vectors are: (equiv. to coeff. of the plane)
n1:<1,1,1>
n2:<1,7,7>
The cross product n1 x n2
vl=
i j l
1 1 1
1 7 7
=<7-7, 1-7, 7-1>
=<0,-6,6>
Simplify by reducing length by a factor of 6
vl=<0,-1,1>
By observing the equations of the two planes, we see that (2,0,0) is a point on the intersection, because this points satisfies both plane equations.
Thus the parametric equation of the line is
L: (2,0,0)+t(0,-1,1)
or
L: x=2, y=-t, z=t
Step-by-step explanation:
5000 x 3 + 3.5% of 5000 x 3 = the answer
The formula is
A=p (1+r/k)^kn
A future value?
P present value 4000
R interest rate 0.057
K compounded monthly 12
N time 4years
A=4,000×(1+0.057÷12)^(12×4)
A=5,021.63
