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.
