If a+b+c = 0 then find x^b-1^c-1 * X^c-1^a-1 *x^b-1^a-1

Ab and bc form a right angle at point b. if a= (-3,-1) and b= (4,4) what is the equation of bc?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212

What is the area of the shaded sector?
