Which is the graph of f (x) = 3 (two-thirds) Superscript x?
Contact [7]

Shown below

<h2>Explanation:</h2>

The function is as follows:

f(x)=3(\frac{2}{3})^x

This is an exponential decay because 2/3. So, let's find some important points:

y-intercept:

This occurs when x=0, so:

f(x)=3(\frac{2}{3})^x \\ \\ f(x)=3(\frac{2}{3})^0 \\ \\ f(x)=3(1) \\ \\ f(x)=3 \\ \\ \\ So, \ point \ (0,3) \ is \ solution \ to \ the \ graph \ of \ the \ function

Find another point:

For \ x=1 \\ \\ f(x)=3(\frac{2}{3})^1 \\ \\ f(x)=2 \\ \\ \\ So, \ point \ (1,2) \ is \ also \ a \ solution

Finally, the exponential function passes through these two points as indicated below.

5. Find the volume of the composite space figure to the nearest whole number. (1 point)
-BARSIC- [3]

Answer:

  (d)  944 mm³

Step-by-step explanation:

The volume of a prism is given by the formula ...

  V = Bh

where B is the area of the base, and h is the distance between bases.

__

<h3>base area</h3>

Here, the base of the prism is a rectangle with a semicircle on top. The circle has a diameter of 9 mm, so a radius of 4.5 mm. The area of the semicircle is ...

  A = 1/2πr² = 1/2π(4.5 mm)² ≈ 31.809 mm²

The area of the rectangle is the product of its length and width.

  A = LW = (9 mm)(6 mm) = 54 mm²

So, the total base area is ...

  31.809 mm² +54 mm² = 85.809 mm²

<h3>prism volume</h3>

The prism volume is this area multiplied by the length of the figure:

  V = Bh = (85.809 mm²)(11 mm) ≈ 944 mm³

The volume of the figure is about 944 mm³.
