To which real number subset does the number -5 belong ?

Subsets That Make Up the Real Numbers. The set of real numbers is made up of the rational and the irrational numbers. Rational numbers are integers and numbers that can be expressed as a fraction.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
