Which statement is correct about y = cos–1 x? a) if the domain of y = cos x is restricted to (0,π), y = cos-1 x is a function. b) regardless of whether or not the domain of y = cos x is restricted, y = cos–1 x is a function. c) if the domain of y = cos x is restricted to (-π/2, π/2), y = cos-1 x is a function. d) regardless of whether or not the domain of y = cos x is restricted, y = cos–1 x is not a function.

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
