Given is a modulus function |f(x)| that gives absolute value of the signed number written inside it.

For example |x|=2 means x = 2 or -2.

If the absolute value modulus function is zero ( i.e. |f(x)| = 0), then the expression inside the modulus function must be zero as well. It means f(x) = 0.

Now we have |a| = 0. So the possible solution of |a| = 0 must be {0}.

Hence, the answer is {0}.

An artist has completed 1/14 of a painting in 2 weeks. At what rate is she working?
joja [24]

Answer:

Rate = 0.035 per weeks

Step-by-step explanation:

Given that,

An artist has completed 1/14 of a painting in 2 weeks.

We need to find the rate at which she is working. Let the rate is R. It can be calculated by dividing part that is completed and time.

R=\dfrac{\dfrac{1}{14}}{2}\\\\R=0.035\ \text{per weeks}

Hence, her rate is 0.035 per weeks.
