The area of the top of a desk which is shown and the dimensions of the top is 5 feet and 2 feet, is 10 squared feet.

<h3>What is the area of a rectangle?</h3>

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

A=a\times b

Here, (a)is the length of rectangle and (b) is the width of the rectangle

A drawing of the top of a desk is shown.

  • 5 feet
  • 2 feet

The image of drawing ins not given in the problem. Here, the length of the desk is 5 feet and the width of the desk is 2 feet according to the data.

a=5\rm\; feet\\b=2\rm\; feet

Put the values in the above written formula as,

A=5\times 2A=10\rm\; ft^2

Thus, the area of the top of a desk which is shown and the dimensions of the top is 5 feet and 2 feet, is 10 squared feet.

17. Identify the amplitude, period, and vertical shift for the
Stella [2.4K]

Answer:

f(x)=2cos(x+\frac{\pi}{2})+3

Step-by-step explanation:

Because the function is symmetric about the y-axis, using the cosine function is most appropriate.

<u>Refer to the equation for a cosine function:</u>

<u />f(x)=acos(bx+c)+d<u />

Amplitude: |a|

Period: \frac{2\pi}{|b|}

Phase shift: -\frac{c}{b}

Midline: y=d

The amplitude would be the average of the maximum and minimum y-values of the function, which would be |a|=|\frac{5-1}{2}| =|\frac{4}{2}| =|2|=2.

The value of b in \frac{2\pi}{|b|} represents the length of the period, so since the length of the period is 2\pi, this means that b=\frac{2\pi}{|2\pi|} =1.

The phase shift, -\frac{c}{b}, describes the horizontal shift of a function. Because the phase shift is -\frac{\pi}{2}, then we can set up the equation -\frac{\pi}{2}=-\frac{c}{1} where we determine c=\frac{\pi}{2}.

The midline (or vertical shift), d, is the horizontal line that passes through between the maximum and minimum points, which the function oscillates. In this case, the midline would be located at the line y=3, therefore, d=3.

Putting all our information together, your final equation is:

f(x)=2cos(x+\frac{\pi}{2})+3

Help ASAP 100 PTS!!!!
Lana71 [14]

Answer:

39

Step-by-step explanation:

Find the value of f(x) at both points

f(3) = 3(3)³ + 1 = 82

f(1) = 3(1)³ + 1 =  4

---------------------------

Average Rate of Change is just like slope

Divide the change in f(x) by the change in x

r = (82 - 4) / (3 - 1)

r = 78/2

r = 39
