An energy department has estimated that solar power plants covering 4242 square miles, or 38% of a certain western state, could generate enough electricity to meet the needs of the entire country. find the area of the state

Let x be the area of the state.

Solar power plants covering 4242 square miles or 38% area.

So,

= 11,163 miles approximately.

Hence, area of the state is 11,163 miles approximately.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
