The Hoover Dam in the U.S produces 2 x 10 ^9 Watts of electricity and is composed of 7 x 10^9 kg of concrete. Concrete requires

kondaur [170]

Answer:

1) $7 x 10^{15} J$

2) $40.5$ days

Step-by-step explanation:

1) First of all we use $1MJ=1x10^{6}J$ so the total energy will be $7x10^{9} kg * 1x10^{6} \frac{J}{kg} =7x10^{15}J$ .

2)Then we use $1W=1\frac{J}{s}$ and $Time=\frac{7 x 10^{15} J }{2x10^{9}J/s} =3.5x10^{6}s$ or $3.5x10^{6}s*\frac{1h}{3600s}*\frac{1day}{24h} =40.5 days$

A plane curve is defined by the following paramedic equation:

vazorg [7]

X = 2 cos t and y = sin t \\ For the given parametric equations the common between them is t \\ So. The parameter is t. \\ The general coordinates for the points of the curve will be (x,y) \\ So, the coordinates will be ( 2 cos t , sin t )
The correct answer is option C
C) the parameter is t and the curve contains the set of points (2cos(t),sin(t))
