Finding the extreme point :
Now,
f''( x ) at x = 1/3 and -1 is :
Therefore, it is maximum at x = -1 and minimum at x = 1/3 .
Hence, this is the required solution.
the complete question is
While driving in an exotic foreign land you see a speed limit sign on a highway that reads 180,000 furlongs per fortnight. How many miles per hour is this? (One furlong is 1/8 mile, and a fortnight is 14 days. A furlong originally referred to the length of a plowed furrow.)
Step 1
<u>convert (furlongs per fortnight) to (miles per fortnight)</u>
180,000 furlongs per fortnight=180,000*(1/8)=22,500 miles per fortnight
Step 2
<u>convert miles per fortnight to miles per hour</u>
1 day=24 hour
14 day=24*14=336 hours
22,500 miles per fortnight=22,500/336=66.96 mph
therefore
<u>the answer is</u>
66.96 mph
Just remember that 1 mile is equal to 5,280 feet.
If we have 5 miles, we need to multiply it my 5,280 which would equal 26,400.
Then we have the other 529 feet that they gave. Just add 26,400ft and 529ft and they will equal 26,929 ft.
Hope it helped! Remember, five tomatoes! (five two eight oh(0)).
Answer:
34
Step-by-step explanation:
In PEMDAS, you do parenthesis first. So you do 14/2 (7) and 18+5 (23).
Now that the parenthesis are gone, adding is the only thing we can do, so you add 7, 23, and 4 to get 34.
