Answer:
trianhle 180⁰
this is well equal triangle
so that angle60⁰
800-200=600 is a good estimate
Hmmm, as I read it, in year 1, but it doesn't say at the beginning of the year or end, so we'll be assuming is at the beginning of year 1, the amount is 850, how much will it be at the beginning of year 6? namely, 5 years later.

Answer:
I.
A is a 4 x 5 matrix => A: U -> V, dim U = 5, dim V = 4
Null space is exactly two dimensional plane
dim null (A) = 2
II.
Rank A = dim U - dim Null A = 5 - 2 = 3
III.
Number of linearly Independent columns of A is the rank of A = 3
IV.
Yes, The system Ax = b has no solution sometimes as range of A \neq V
V.
Yes,Sometimes Ax = b has a unique solution
VI.
Yes, sometimes Ax = b has infinitely many solutions
Answer:
x = 5
Step-by-step explanation:
2² x 2³ = 2^x
Laws of indices states that when the base is same the powers can be added when two terms are multiplied,
2^(2+3) = 2^x
2⁵ = 2^x
x = 5
