Let the function f(x) have the form f(x)=acos(x+c) to produce a graph that matches the one shown below wht must the value of a be ?

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

i believe it is d.) buddhism and e.) hinduism
