Miracle Friedman · Answer 1

Length: L=8 feet

Width: W=2 feet

Center is located at 0,0 → C = (0,0) = (h, k) →h=0, k=0

The surfboard is lying on the ground horizontally:

x^2/a^2+y^2/b^2=1

L=2a→2a=8 feet

Solving for a:

2a/2 = (8 feet) / 2

a=4 feet

W=2b→2b=2 feet

Solving for b:

2b/2 = (2 feet) / 2

b=1 feet

Replacing a=4 and b=1 in the equation (1):

(1) x^2/a^2+y^2/b^2=1

x^2/4^2+y^2/1^2=1

x^2/16+y^2/1=1

x^2/16+y^2=1

Answer: Equation of the sufboard:

x^2/16+y^2=1
