The answer is 243 patches.
Step-by-step explanation:
Area of a rectangular piece of fabric = 15 × 9 = 135 cm²
Area of 27 pieces of fabric = 135 × 27 = 3645 cm²
Number of patches can be cut from = 3645 ÷ 15 = 243

Use Pythagoras' theorem:
a^2 + b^2 = c^2
Sub the values in:
10^2 + 10^2 = c^2
200 = c^2
Square root to find the answer:
c = 14.14

Answer:
Vertex is (2,1) according to your information. In general, V(h,k). Equation must be y - k =a(x-h)2 for any quadratic function (parabola). Furthermore, you know that (0,5) is a point on the curve, so substitute for h, k, x and y to determine what coefficient "a" has to be.
