If g(x) = {(4, -5), (-3, 2), (-6, 1), (1,0)}, which set of ordered pairs represents
Ket [755]

Answer:

The inverse of g(x) is {(-5, 4), (2, -3), (1, -6), (0, 1)} ⇒ (A)

Step-by-step explanation:

To find the inverse of a function switch x and y

<u>Example:</u>

If f(x) = {(1, 2), (-4, 5), (0, 0)}

To find its inverse switch x and y in each ordered pair

The inverse of f(x) = {(2, 1), (5, -4), (0, 0)}

<em>Let us do the same with our question</em>

∵ g(x) = {(4, -5), (-3, 2), (-6, 1), (1, 0)}

→ Switch x and y coordinates in all ordered pair

∴ The inverse of g(x) = {(-5, 4), (2, -3), (1, -6), (0, 1)}

<em>Look at the answer to find the correct choice</em>

It is (A)

A swimmer does 3,560 J of work in 55 s. What is the swimmer's power output? Round your answer to two significant
Vesna [10]

Answer:

64.73 Watts

Step-by-step explanation:

We are given;

  • Work done by the swimmer = 3,560 J
  • Time, t = 55 seconds

We are required to calculate the power of the swimmer;

  • We need to know that power is the rate of doing work
  • That is, Power = Work done ÷ time

Therefore;

Power of the swimmer = 3,560 Joules ÷ 55 seconds

                                      = 64.727 Watts

                                      = 64.73 Watts

Thus, the power output of the swimmer is 64.73 watts
