Choose the true biconditional statement that can be formed from the
conditional statement "if a number is divisible by 2, then it is even" and its
converse
o
a. a number is not divisible by 2 if and only if the number is not even
b. a number is not divisible by 2 if and only if the number is odd.
o
c. a number is divisible by 2 if and only if it is even.
o
d. a biconditional cannot be formed because the statement and its
converse are not logically equivalent.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

1     sepan

2     encuentren

3     tenga

4     hable

5   parezca

6   llegue

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
