(3 x 3) + (3 x 6)
Because length of fig, 1 (the smaller one) is 3, which needs to be multiplied by 3 (the width)
Then the 6 needs to be multiplied by the width of three to find the area

A(3,4),B(5,8),C(7,8) are the vertices of ABC, prove that the line passing through the mid point of AB and AC is parallel to BC
Ede4ka [16]
<h2>Explanation:</h2><h2></h2>

The \ midpoint \ formula \ of \ the \ line \ segment \\ that \ joins \ the \ two \ points \ (x_{1},y_{1}) \ and \ (x_{2},y_{2}) \ is \\ given \ by \ the \ following \ Midpoint \ Formula:\\ \\ Midpoint=(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})

<h2></h2>
  • Let's name the mid point of AB as c
  • Let's name the mid point of AC as p

Then:

c=(\frac{3+5}{2},\frac{4+8}{2}) \\ \\ c=(\frac{8}{2},\frac{12}{2}) \\ \\ c=(4,6) \\ \\ \\ p=(\frac{3+7}{2},\frac{4+8}{2}) \\ \\ p=(\frac{10}{2},\frac{12}{2}) \\ \\ p=(5,6)

So the slope of the line that passes through c \ and \ p is:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m_{cp}=\frac{6-6}{5-4}=0

And the slope for BC is:

m_{BC}=\frac{8-8}{7-5}=0

As you can see, both slopes are zero, so these are horizontal lines.

A buoy oscillates in simple harmonic motion y= A cos cos as waves move past it. The buoy moves a total of 3.5 feet (vertically)
NNADVOKAT [17]

Answer:

a) y = 1.75 ft cos (\frac{\pi}{5}t)

b) v(t) = -1.0995 sin (\frac{\pi}{5}t)

Step-by-step explanation:

Part a

Since the buoy oscillates in simple harmonic motion the equation to model this is given by:

y = A cos (wt +\theta)

For this case from the info given we know that:

2A = 3.5 , A = \frac{3.5}{2}= 1.75 ft

"It returns to its high point every 10 seconds." That means period =10 T =10s, and the angular frequency can be founded like this:

w = \frac{2\pi}{10}= \frac{\pi}{5}

Assuming that the value for the phase is \theta =0 our model equation is given by:

y = 1.75 ft cos (\frac{\pi}{5}t)

Part b

From definition we can obtain the velocity with the derivate of the position function and if w calculate the derivate we got this:

\frac{dy}{dt}= v(t) = -1.75 ft (\frac{\pi}{5}) sin (\frac{\pi}{5}t)

v(t) = -1.0995 sin (\frac{\pi}{5}t)
