6 Book sales in the U. S. totaled $16 billion in 1991. Sales increased about $1 billion a year until 2014. Write an equation to find the total sales (S) for any year (t) between
1991 and 2014. If this trend continues, what should sales be in 2020?

About 20,000 fewer babies were born in California in 1996 than in 1995. In 1995, about
560,000 babies were born. Write an equation that can be used to predict the number of
babies born (x) years after 1995 if this trend continues.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

i would you but i don't under stand the qustion

step-by-step explanation:

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
