Select the statements that are true based on the following given information. D={xl x is a whole number}
E = {x\ x is a perfect square < 36)
F = {x\ x is an even number between 20 and 30)
The expression Dn Eis (1, 4, 9, 16).
The expression DNF is (12, 14, 16, 18)
DU (En F) is (all whole numbers).
(En F) is the empty set.
The expression D N (E U F) is 25

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

the answer is 2/54

step-by-step explanation:

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
