The price for 3 sandwiches amounts to $18. Since the cost, c, of a ham sandwich directly correlates with the quantity, n, and is told that c equals $54 for 9 sandwiches, the cost per sandwich is $6. Multiplying $6 by 3 gives a total of $18.
(10x)^(-3)
= 1/[(10x)^3]
= 1/[10^3 * x^3]
= 1/(1000x^3)
The final result is 1/(1000x^3), and none of the given choices seem correct. (Option C would be correct if it used round brackets.)
Hope this helps~

Further clarification
Trigonometry is a branch of math focused on the connections between the sides and angles of triangles.
Considering special angles of trigonometric functions, for instance

In the equation y = cos⁻¹ 0, the value of y can be derived as follows:
y = cos⁻¹0
y = arc cos 0
cos y = 0
Thus, the resulting value of y:

Alternatively, it can be expressed as:
⇒ y: arithmetic sequence
So there are infinite solutions for y

Part 1) The radius of the circle is r=17 units. Part 2) The points (-15,14) and (-15,-16) are situated on this circle. Step-by-step explanation: Step 1 Find the radius of the circle. We know that the distance from the center of the circle to any point on its circumference equals the radius of the circle. The formula to determine the distance between two points is equal to......we have (-7, -1) and (8, 7) substitute... Step 2 Determine the y-coordinate of point (-15,y). The standard form of the circle's equation is given by... where (h,k) represents the center, and r is the radius. Replace the values, substituting x=-15 in the equation... square root both sides... ultimately, we find two solutions: point (-15,14) and point (-15,-16) refer to the attached figure for a clearer understanding of the problem.
