The area of one jellyfish is pi r squared or 3.14 x 1 squared (the diameter of the jellyfish is 2 feet so the radius is 1 foot) or essentially 3.14 square feet. 2000 x 3.14 = 6280 square feet. The area of the ocean floor is 120 x 360 feet or 43200 square feet. So 6280/43200 is equal to 0.15 or 15%

Eliminate the parameter t. Find a rectangular equation for the plane curve defined by the parametric equations.

djverab [1.8K]

Answer:

1. C

2. C

Step-by-step explanation:

1. x = $\sqrt{t}\\$ , y = 4t +3

Solve for t:

t = $x^{2}$

Plug in t:

y = 4( $x^{2}$ ) +3

y = 4 $x^{2}$ +3

2. x = 2t, y = t + 2

Solve for t:

t = x/2

Plug in t:

y = 1/2x + 2
