This Question: 1 pt 17 of 17 (16 complete) The graph shows an idealized description of te temperature (in ) for approximately the last 150 rousand years of a location at the same latitude Complete parts (aHd) (a) Find the highest and lowest temperatures recorded The highest temperature isTF The lowest temperature isF (b) Use these two numbers to find the amplitude The amplitude is (c) Find the period of the function The period is y 140,000 105,000 70 000 Years age (d) What is the trend of the temperature now? 0 downward O upward

Explanation / Answer

High = 70
Low = 40

---------------------------------------------------

Ampl = (max - min)/2
A = (70 - 40)/2
A = 30/2
A = 15 ---> ANS

---------------------------------------------------

Period :
Clealy difference between two max-es is t = 35000 and t = 70000
So, period = 70000 - 35000

Period = 35000 --> ANS

---------------------------------------------------

Over each period, half of the period is where the temperature is increasing and the other half decreasing

Notice from t= 35000 to 52500, tis decreasing
And from t - 52500 to t = 70000, tis increasing

Similarly from t = 140000 to t = 157500, tis decreasing

So, yes, since this is within the 150000 yrs thats given in the question, it is on a DOWNWARD TREND
