A sample of an unknown chemical element naturally loses its mass over time. The relationship between the elapsed time , in days, since the mass of the sample was initially measured, and its mass, M(t)M(t)M(t)M, left parenthesis, t, right parenthesis, in grams, is modeled by the following function:
M(t)=900⋅(827)t
Complete the following sentence about the rate of change of the sample. Round your answer to two decimal places.
The sample loses 13\dfrac{1}{3}31start fraction, 1, divided by, 3, end fraction of its mass every
days.

step-by-step explanation:

answer

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

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
