The value of
is 31
Explanation:
The given expression is 
We need to determine the value of 
The value of
can be determined by substituting
in the expression 
Thus, we have,

Adding the terms, we have,

Thus, the value is 31.
Therefore, the simplified value of the expression by substituting
in the expression
is 31.
Answer:
This is a theory.
Step-by-step explanation:
The sialic continents, mafic ocean floors, the crust, the mantle and the core were all formed while the early melted Earth cooled and differentiated as low density minerals floated to the surface and heavy, denser minerals sank to the center.
This is a theory.
Answer: The 0.09 is 1/10 of 0.9
Step-by-step explanation:
You can see by the decimal point that it moved so from 0.9 to 0.09 it has moved once.
X to the second =4×3
x=√(12)
x=3.4641016151
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

This is the equation of a vertical parabola open up
The vertex is a minimum
Convert to vertex form
Complete squares

Factor the leading coefficient



Rewrite as perfect squares

The vertex is the point (-1.5,-1.5)
Find the zeros of the function
For y=0


square root both sides




Find the y-intercept
For x=0

The y-intercept is the point (0,3)
therefore
The graph in the attached figure
