F(x)= x-9 , g(x) = 3x^2 what is (f+g)(x) , (f-g)(x) , (fg)(x)

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
