Answer:
The walk will cost $8164.
Step-by-step explanation:
Given:
Diameter of the circular pond (D) = 24 yd
Width of the gravel path (x) = 2 yd
Cost per yard of the path = $50
Now, radius of the circular pond is half of the diameter and is given as:

Now, area of the pond is given as:

Area of the complete path including the pond area is given as:

Now, area of the gravel path can be obtained by subtracting the pond area from the total outer area. This gives,

Now, using unitary method,
Cost of 1 square yard of path = $50
∴ Cost of 163.28 square yard of path = 50 × 163.28 = $8164
Hence, the walk will cost $8164.
If you work with real numbers then the square root of - 1 CANNOT be defined.
If you work with complex numbers then the square root of - 1 is equal to the imaginary unit(which is symbolized as i)
imagine the diagonal of a rectangle being the split between two triangles. you are trying to find the longest side of the triangle, which is the "diagonal" of the rectangle.
to find the length of a side of a triangle, use the Pythagorean theorem. it is : a^2 + b^2 = c^2
so... plug in your data like this...
15^2 + 12^2= c^2.
225 + 144 = the square root of 369.
that is rounded to 19.2

Answer:
y= -3
Step-by-step explanation:
I'll assume it is a linear line (straight line).
Sense the y-value doesn't change and stays -3, the equation for the line would be y= -3
And just so you know, the slope of the line would be 0.
