Answer:
The augmented matrix is of two equations, and two variables.
Step-by-step explanation:
This is an augmented matrix, which means the constant terms are on the last column.
The matrix can be written as
X1 + kX2 = 3
-5X1 + 6X2 = 1
The constants are 3, 1, and all the coefficients of the variables, X1 and X2.
X1 and X2 can take any values.
k is constant, just like 1, -5, and 6.
Though, it is not specified, the consistency or inconsistency of the equation depends on the value k takes.
Answer:
45ft
Step-by-step explanation:
use pythagoras
c²=a²+b²
47²=15²+b²
(solve for b)
b= 44.5
round off, =45
