Jade invested in the stock market. The weekly change in value of her stock, in dollars, over 4 weeks was +23.65, -22.20, -12.75

Anastasy [175]

Answer:

<h3>The average weekly change in value of Jade's stock in dollars is -1.3225</h3>

Step-by-step explanation:

Given that Jade invested in the stock market.

The weekly change in value of her stock, in dollars, over 4 weeks was +23.65, -22.20, -12.75 and +5.98.

<h3>To find the average weekly change in value of her stock in dollars :</h3>

The average weekly change in value of Jade's stock is given by $Average=\frac{sum of the weekly changes in value of her stock in dollars}{total number of weeks}$

$Average=\frac{23.65+(-22.20)+(-12.75)+5.98}{4}$

$=\frac{23.65-22.20-12.75+5.98}{4}$

$=\frac{29.63-34.92}{4}$

$=\frac{-5.29}{4}$

$=-1.3225$

Therefore Average=-1.3225

<h3>Therefore the average weekly change in value of Jade's stock in dollars is -1.3225</h3>

Iver a 24-hour period, the tide in a harbor can be modeled by one period of a sinusoidal function. The tide measures 4.35 ft at

enot [183]

Answer:

$f(x)=3.95sin(\frac{\pi}{12}x)+4.35$

Step-by-step explanation:

<u>Recall:</u>

Sinusoidal Function -> $f(x)=a*sin(bx+c)+d$
Amplitude -> $a$

Period -> $\frac{2\pi}{|b|}$
Phase Shift -> $-\frac{c}{b}$

Vertical Shift/Midline -> $d$

<u>Given:</u>

Amplitude -> $a=8.3-4.35=3.95$
Period -> $\frac{2\pi}{|b|}=\frac{2\pi}{|24|}=\frac{2\pi}{24}=\frac{\pi}{12}$
Phase Shift -> $-\frac{c}{b}=-\frac{0}{24}=0$
Vertical Shift/Midline -> $d=\frac{8.3+0.4}{2}=\frac{8.7}{2}=4.35$

<u>Conclusion:</u>

The equation that models the situation is $f(x)=3.95sin(\frac{\pi}{12}x)+4.35$

Hope this helped! I've attached a graph of the function so you can understand it better!

Answer:

True

Step-by-step explanation:

The triangles are both right triangles, meaning they can be used with pythagorean theorem. If the triangles CAD and CBD share the same "hypotenuse" (CD), and they have a pair of congruent sides, they other pair of sides must be able to fit into the pythagorean theorem/
