Rewrite each of the following sentences using mathematical notation (∀, ∃, and state whether the sentence is true or false with a brief reason.
(a) for every integer there is a smaller real number.
(b) there exists a real number that is smaller than every integer.

(a) For each integer there is a smaller real number, it is equivalent to the expression: ∀x∈Z, ∃y∈R, so that, real number y is less than the integer number x. (Z represents the set of integers numbers and R represents the set of real numbers)

(b) There is a real number that is smaller than each integer, it is equivalent to the expression: ∃y∈R, such that, ∀x∈Z, that number y has to be less than integer number x. (Z represents the set of integers numbers and R represents the set of real numbers)

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

28

step-by-step explanation:

because that's the answer
