The equation of a sphere centered at (h, j, k) with radius r is
... (x -h)² +(y -j)² +(z -k)² = r²
The sphere can have a radius no larger than the distance to the nearest octant boundary, one of x=0, y=0, or z=0. That is, the radius must be 3, so the equation is
... (x -3)² + (y -3)² + (z -6)² = 9

The product of 2 × 9 × 4 gives us; 72
<h3>Commutative Property</h3>
We want to find the product of three numbers which are 2, 9 and 4. This is expressed as;
2 × 9 × 4
Now, this is multiplication and we can use commutative property whereby;
a × b × c = (a × b) × c
Thus;
2 × 9 × 4 = (2 × 9) × 4
>> 18 × 4
>> 72
Thus, the product of 2 × 9 × 4 gives us 72

Answer:
$1000.
Step-by-step explanation:
Let x represent number of years.
We have been given that Tommy purchased a riding lawnmower with an original value of $2,500. The value of the riding lawnmower decreases by $300 per year. We are asked to find the value of lawnmower after 5 years.
Since the value of the riding lawnmower decreases by $300 per year, so value of lawnmower decrease in 5 years would be 5 times $300.
The final value of lawnmower would be initial value minus value decreased in 5 years.
![\text{The value of the lawnmower after five years}=\$2500-\$300(5)](https://tex.z-dn.net/?f=%5Ctext%7BThe%20value%20of%20the%20lawnmower%20after%20five%20years%7D%3D%5C%242500-%5C%24300%285%29)
![\text{The value of the lawnmower after five years}=\$2500-\$1500](https://tex.z-dn.net/?f=%5Ctext%7BThe%20value%20of%20the%20lawnmower%20after%20five%20years%7D%3D%5C%242500-%5C%241500)
![\text{The value of the lawnmower after five years}=\$1000](https://tex.z-dn.net/?f=%5Ctext%7BThe%20value%20of%20the%20lawnmower%20after%20five%20years%7D%3D%5C%241000)
Therefore, the value of lawnmower after years would be $1000.
