Answer:
164
Step-by-step explanation:
Checkpoint 2= -187
Checkpoint 1= -23
The negatives mean how much lower they are from the surface.
To find "how much lower," we need to subtract -23 from -187.
-187-(-23) is the same as -187+23 (2 negatives=1 positive)
-187+23= -164.
However, it's not negative in the answer because by asking how much lower, we don't need to have a negative. "How much lower" is a distance, and a distance is always positive.
Answer:
C) II only
Step-by-step explanation:
Given the 2×2 matrix A = [1 1, 0 1]
The only statement true there is (II) only i.e the matrix is not diagonalizable but invertible. A matrix is invertible if the product of the matrix and its inverse is equal to an identity matrix
The rank of the matrix is not 1 but 2 because rank of a matrix is the number of non zero rows of a matrix and the number of non zero rows of this matrix is 2 thereby making I incorrect.
Also note that the sum of nullity and rank is equal to the number of columns of the given matrix
Nullity + rank = number of columns
Nullity = number of columns - rank
Nullity = 2-2 = 0
The nullity is therefore 0 not 1 making option III also false

Answer:
a). (5,30) (0,20)
b). (40,130) (35,120)
Step-by-step explanation:
a). (5,30) (0,20)
solid red line's solutions are all going to be going down and dashed blue line's solutions will be going up all solutions in those regions are considered solutions
b). (40,130) (35,120)
points are non-solutions because they are not in the shaded region for either line's solution .
haven't done this in a hot minute so im not sure 100%
