Which of the following describes the function shown in the table below? x y -4 16 -1 2 2 0.25 4 0.0625 5 0.03125 exponential, th
wolverine [178]

A statement which best describes the function shown in the table is: B. exponential, there is a continual rate of decay or decrease.

<h3>What is an exponential function?</h3>

An exponential function is a mathematical function whose numerical values (numerals) are generated by a constant that is raised to the power of an argument.

<u>Given the following table:</u>

X : -4        -1        2            4              5

Y :  16        2       0.25   0.0625    0.03125

Next, we would calculate the rate of decay for the y-values:

16/2 = 2/0.25 = 0.25/0.0625 = 0.0625/0.03125 = 8

<u>Rule:</u> The y-values constantly decreases by 1/4 or 0.25 of the previous number.

In conclusion, we can logically deduce that the function shown in the table is exponential, there is a continual rate of decay or decrease.

A sawdust pile has a base diameter of 35 feet when it’s height is 30 feet, find the volume of the pile when it is at 50 feet tal
ladessa [460]

Answer:

The volume of the sawdust pile is 16041.7 feet.

Step-by-step explanation:

The sawdust pile formed is in the form of a cone.

The volume of a cone is:

V=\frac{1}{3}\ \pi r^{2}\ h

The information provided is:

<em>r</em> = radius of the base = diameter ÷ 2 = (35 ÷ 2) feet

<em>h</em> = height = 50 feet

Compute the volume of the sawdust pile as follows:

V=\frac{1}{3}\ \pi r^{2}\ h

   =\frac{1}{3}\times \frac{22}{7}\times (\frac{35}{2})^{2}\times 50\\\\=16041.6667\\\\\approx 16041.7\ \text{feet}

Thus, the volume of the sawdust pile is 16041.7 feet.
