Answer:
Step-by-step explanation:
Given are three vectors in set B.
To show that B is dependent
The determinant
Hence vectors are dependent
b) The given equation
Let us try parametrically
These 3 vectors are collinear and hence equation would be
c) Basis for B would be only 2 dimensional
i.e. any two vectors out of 3 form basis
The basis would be (1,0,1) and (0,1,2)
Answer:
Step-by-step explanation:
In this question we have to find the expression for the value of temperature in terms of degrees Celsius.
Since, the given expression is,
F = 1.8C + 32
F - 32 = 1.8C + 32 - 32
F - 32 = 1.8C
For F = C,
C - 32 = 1.8C
C - 1.8C = 32
-0.8C = 32
C =
C = -40
Therefore, at (-40°C) degrees of temperature degrees Fahrenheit and degrees Celsius are equal.
