The following formula gives the distance between two points (x1 , y1
) and (x2
, y2
) in the

Cartesian plane: √(x2−x1
)
2
+( y2−y1
)
2
.

Given the center and a point in a circle, you can use this formula to find the radius of the circle.
Write a program that prompts the user to enter the center and a point on the circle. The
program should then output the circle’s radius, diameter, circumference and area.

You should try to photograph people on bright sunny days because the light will be best a) true b) false

Assume that to_the_power_of is a function that expects two int parameters and returns the value of the first parameter raised to the power of the second parameter. write a statement that calls to_the_power_of to compute the value of cube_side raised to the power of 3 and that associates this value with cube_volume.

Write a function balancechemical to balance chemical reactions by solving a linear set of equations. the inputs arguments are: reagents: symbols of reagents in string row array products: symbols of products in string row array elements: elements in the reaction in string row array elcmpreag: elemental composition of reactants in two dimensional numeric array elcmpprdcts: elemental composition of prducts in two dimensional numeric array hint: the first part of the problem is setting up the set of linear equations that should be solve. the second part of the problem is to find the integers from the solution. one way to do this is to mulitiply the rational basis for the nullspace by increasing larger integers until both the left-and right-side integers exist. for example, for the reaction that involves reacting with to produce and : reagents=["ch4", "o2"]; products =["co2", "h2o"]; elements =["c","h", "o"] elcmpreag=[1,4,0;
