A man wants to beautify his front yard by planting four 20−foot-tall palm trees alongside his house. Each tree will need a cylin
GREYUIT [131]

He have to buy 4 bags to put all the dirt at once.

Step-by-step explanation:

Radius = 17 inches

Height = 28 inches

Volume of dirt from the cylindrical hole = π(r x r) h

= π(17 x 17) 28

= (3.14) (289) 28

= 25408.88 cubic inches

1 foot = 12 inches

Volume of dirt the bag can hold= 24 x 18 x 48

= 20736 cubic inches of dirt

The man fills only one third of the bag.

The volume of dirt the man fills = (1/3)20736

= 6912 cubic inches

Total bags = 25408.88/6912

= 3.69

= appx. 4 bags

He have to buy 4 bags to put all the dirt at once.

Due to length restrictions, we kindly invite to read the explanation of this question and the image of parabola on <em>Cartesian</em> plane attached below to see the results.

<h3>How to graph a quadratic function </h3>

To graph a parabola, we shall follow the following procedure:

  1. Mark the vertex of the parabola on the <em>Cartesian</em> plane.
  2. Mark at least two pairs of values on the <em>Cartesian</em> plane, one on the right of the vertex and other on the left of the vertex.
  3. Match the points to create the resulting curves.

By following all the steps, we generate the curve with the help of a graphing tool.

Find the equalivent exponential expression of (9^3)^4
kogti [31]
The rule is:

(a^b)^c=a^(b*c)

In this case:

(9^3)^4=9^(3*4)=9^12

and if you wanted it more simplified you could say:

9^12=(3^2)^12=3^(2*12)=3^24
