Calculate the distance between (4,6) (5,0)
kramer

The distance between two (4, 6) and (5, 0) is 6.08 units.

Solution:

The given points are (4, 6) and (5, 0).

x_1=4, y_1=6, x_2=5, y_2=0

<u>To find the distance between two points:</u>

Distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

d=\sqrt{(5-4)^2+(0-6)^2}

d=\sqrt{1^2+(-6)^2}

The value of 1² = 1

The value of (–6)² = 36

d=\sqrt{1+36}

d=\sqrt{37}

d = 6.08

The distance between two (4, 6) and (5, 0) is 6.08 units.

A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, t
matrenka [14]

Answer:

509.35 feet

Step-by-step explanation:

16°23' means 16 degrees and 23 minutes.  A minute is 1/60 of a degree.

16°23' = 16 + (23/60) = 16.383°

Similarly:

49°29' = 49 + (29/60) = 49.483°

When the boat is first noticed:

tan(16.383°) = 200 / a

a = 200 / tan(16.383°)

a = 680.27

When the boat stops:

tan(49.483°) = 200 / b

b = 200 / tan(49.483°)

b = 170.92

So the difference is:

a − b = 680.27 − 170.92 = 509.35

The boat traveled 509.35 feet from the time it was first noticed to the time it stopped.
