distance = |  \frac{(- 4 \times 1) +  (- 1 \times 1)-7}{ \sqrt{ {( - 4)}^{2} +  {( - 1)}^{2}  } } |  \\=   \frac{ - 12}{ \sqrt{17 } }  \\  =  \frac{ - 12 \sqrt{17} }{17}  \\  =  - 2.91

The slope of an absolute function at the point where it evaluates to zero is undefined.
Here, when x=1, so |4x-4|=|4-4|=|0|, the slope is undefined.  This is where the vertex of the "V" on the graph of the absolute value function.

Answer:

d. $300.00

Step-by-step explanation:

Given that a cosmetologist must double her salary before the employer can realize any profit from  his/her work, for Miss. Mead to realize $50.00 profit on her work, you would have to determine the amount that doubles the salary of the cosmetologist and add the $50 needed as profit:

Salary= $125*2=$250

about travels in the following path. How far north did it travel? Round your answer to the nearest 10th of a mile
SCORPION-xisa [38]

Answer:

19.1 miles

Step-by-step explanation:

The situation given represents a right triangle.

Thus, we would use trigonometric function to find how far north the boat travelled.

Let's represent how far the boat travelled north with "x".

Thus:

Reference angle = 23°

Opposite = x

Adjacent = 45 miles

Apply TOA:

Tan 23° = Opp/Adj

Tan 23° = x/45

Multiply both sides by 45

45 × Tan 23° = x

x = 45 × Tan 23°

x = 19.1013667

x = 19.1 miles (nearest tenth of a mile)
