The price for us postage stamps has increased over the years. since 1975, the price has increased from $.13-$.37 in 2005 at a rate that is approximately linear.

write a linear model for the price of stamps during this time. let p represent the price and t represent the number of years since 1975.

what would you expect the price of a stamp to be in 2015?

( show your work)

Linear Equation: P = 0.008T + 0.13

Price of stamp in 2015 = $0.45

Step-by-step explanation:

From 1975 to 2005 [30 years], the price increased from 0.13 to 0.37 [0.24].

This means the rate of change (slope) is 0.24/30 = 0.008

This means Price changed (increased) by $0.008 per year.

Slope = 0.008

The y-intercept (P) is at the starting point which is at T = 1975, the price was 0.13. Hence y-intercept is 0.13

The equation of a line is given as

P = mT + b

Where m is the slope and b is the y-intercept

Now, we can write the linear model equation as:

P = 0.008T + 0.13

To find the price of stamp in 2015, we see that this is 40 years later after 1975. So we plug in 40 into T in the equation found above:

P = 0.008(40) + 0.13

P = $0.45

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
