We are asked to determine the limits of the function cos(2x) / x as x approaches to zero. In this case, we first substitute zero to x resulting to 1/0. A number, any number divided by zero is always equal to infinity, Hence there are no limits to this function.
#42.
14n - 32 = 22
add 32 to both sides
14n - 32 + 32 = 22 + 32
simplify
14n = 54
divide both sides by 14
14n/14 = 54/14
simplify
n = 3 12/14
n = 3 6/7 or n = 3.857
Since 19 is a prime number it is not divisible by 2. So its only divisible numbers are 1 and 19 itself. So 19 multiplied by 1 equals 1
The water bill was 1/5 of the total, so was 0.2*$540 = $108.
