Adoctor observes a graph that shows the electrical activity (in volts) of the heart of a patient over a period of time (in seconds). each local maximum of 0.004 volts corresponds to one heartbeat. the doctor needs to calculate the heart rate of the patient in beats per minute. what is the heart rate of this patient?

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?

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

(1 km=1000m, 1m=100 cm)
