Write a piecewise function

Mathematics
1 answer:
Hoochie [10]3 years ago
7 0

Answer:

The answer to your question is:

        f(x) =        - x - 4          if   (-∞, -3)

                       2x + 6          if     [-3, ∞)

Step-by-step explanation:

Find the equations of the two lines

Blue line

A (-4, 1)

B (-6, 3)

              m = (3 - 1) / (-6 + 4)

              m = 2 / -2

              m = -1

                        (y - 1) = -1(x + 4)

                        y - 1 = -x - 4

                        y = - x - 4 + 1

                       y = - x - 4             Interval (-∞, -3)

Red line

C(-2, 2)

D(0, 6)

             m = (6 - 2) / 0 + 2)

             m = 4 / 2

             m = 2

                       (y - 2) = 2(x + 2)

                       y - 2 = 2x + 4

                      y = 2x + 4 + 2

                      y = 2x + 6           Interval [-3, ∞)

In the figure above abc is a square .. what is the value of x?
Len [333]

If ABCD is a square, then m∠A = 90°.

Therefore we have the equation:

30° + 48° + x° = 90°

78° + x° = 90° |-78°

x° = 12°

Answer: 12

The captain of a boat knows that a lighthouse on the coast is 100 ft
Tatiana [17]

Answer:

Height of the light house =7.5\ feet

Step-by-step explanation:

Distance of light house from boat = 100 ft

Angle of elevation from boat to the top of light house = 2°

Height above water while taking measurement = 4 ft

The figure of the situation is shown below.

For Δ ABC

\tan2\°=\frac {AB}{BC}

\tan2\°=\frac {AB}{100}

0.035=\frac {AB}{100}

Multiplying both sides by 100.

100\times 0.035=100\times\frac {AB}{100}

3.5=AB

∴ AB=3.5

Height of the light house =3.5+4=7.5\ feet

Please help <3 Paula is writing short, casual notes for how to find the inverse of a function, f. Those notes are shown below
NARA [144]

Answer:

(3rd listed choice) Paula's notes are incorrect. Step 4a should be "If the result does not define y as a function of x, then f does not have an inverse," and step 4b should be "If the result defines y as a function of x, then f has an inverse."

Step-by-step explanation:

If f(y) = x can be solved for a relation for y that is a function, then f(x) has an inverse. It will be the function defined by y.
