For the years since 2001, the percent p of high school seniors who have tried marijuana can be considered as a function of time t according to p = f(t) = 0.17t2 − 2.61t + 52.64 where t is the number of years past 2000.† In what year after 2000 is the percent predicted to reach 75%, if this function remains valid?

The year 2021.

Step-by-step explanation:

75% here means a the answer to our function is 75.

Thus, f(t) = 75

Now let's solve the equation for the variable t:

Solving for t using the quadratic formula we get:

t1  = 21.477

t2 = -6.124

As t is the number of years after 2000, and t can not be less than 0, our answer is t1.

This mean the percent is predicted to reach in the middle of the year 2021.

converting the number 0.477 to months we get: 0.477*12 = 5.72

This means the middle of may.

So our answer is May, 2021. And the year is just 2021.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

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.
