Answer:
The statement
is a tautology.

Step-by-step explanation:
We have the following statement:

To reduce the statement to a tautology we need to use the table of logical equivalences as follows:

by the the logical equivalence involving conditional statement.
by the the logical equivalence involving conditional statement.
by the Associative law.
by the Negation law.
by the Domination law.
You can use this formula of arthenatic series to find sum to get the number of term
sum= n÷2 (2a+(n - 1)d)
n= number of tern = n
a= first term =
d= common difference
sum= 1113
you can find the number of series by putting in them
A=p (1+rt)
A future value ?
p Principle 900
R interest rate 0.06
T time 9/12
A=900×(1+0.06×(9÷12))
A=940.5
Answer:
The equivalent expressions are:


Step-by-step explanation:
Given equation for finding area of a trapezoid:

where
represents area,
represents height and
represents the base lengths of the trapezoid.
Evaluating
by rearranging the equation to find an equivalent equation.
Multiplying both sides by 2.


Dividing both sides by
