F(x)= ∫ln²x/x dx= ∫ln²xd(lnx) cause d(lnx)= (lnx)'dx=1/x dx
= ln³x/3 +C with C is constant
In addition, we have f(2)=6, so we have 6=ln³2/3+C
or C= 6- <span>ln³2/3
And f(x)= </span>ln³x/3+ <span> 6- </span><span>ln³2/3</span>
Answer:
V= 452.39
Step-by-step explanation
V=πr2h3=π·42·273≈452.38934
Answer:
correct you are
Step-by-step explanation:
Set up a proportion.
flagpole/shadow = woman/her shadow.
f/s1 = w/s2
f = 42.9
s1 = 253
w = 6.2
s2 = ??? = x
42.9/253 = 6.2 / x
42.9 x = 253*6.2
42.9 x = 1568.6
x = 1568.6 / 42.9
x = 36.56 The womans shadow is 36.56 feet long <<<< ===== answer.
Sally to get to the next town in 2/3 hour.
According to the statement
The distance covered by sally to get next town is 20 miles
Speed at which sally drive is 30 miles per hour
We know that the
TIME = DISTANCE / SPEED
Substitute the values in it and
TIME = 20 / 30
TIME = 2/3 hour
So, Sally to get to the next town in 2/3 hour.
