Answer:

Two possible answers...

Step-by-step explanation:

You didn't specify whether it is am or pm, although it's more logical that it's pm, but I'll answer both anyway.

for 12pm:

when you're adding time, it's best to think in terms of twelve. if you add the first 12 hours, it completes the day and now you're in the tenth day of the month. add the other 10 hours and it is 10 am of the tenth day of the month.

for 12 am:

add just the same, except it's 10pm instead.

Given that y = (e^x)/x, x > 0, find the range of values of x where y is a decreasing

vodka [1.7K]

Answer:

The interval for which y is a decreasing function of x is:

$(0, 1)$

Or as an inequality:

$0$

Step-by-step explanation:

We are given the equation:

$\displaystyle y=\frac{e^x}{x}\, ,x>0$

And we want to find the range of values x for which y is a decreasing function of x.

y is decreasing whenever y' is negative. Find y' using the Quotient Rule:

$\displaystyle y'=\frac{(e^x)'(x)-e^x(x)'}{(x)^2}$

Differentiate:

$\displaystyle y'=\frac{xe^x-e^x}{x^2}$

y is decreasing whenever y' is negative. Thus:

$\displaystyle 0>\frac{xe^x-e^x}{x^2}$

Multiply both sides by x². This is always positive so we do not need to change the sign:

$xe^x-e^x$

Factor:

$e^x(x-1)$

eˣ is always positive. So:

$x-1$

Adding one to both sides produces:

$x$

Therefore, y is a decreasing function of x when x is less than one (and greater than 0).

In interval notation:

$(0, 1)$

Or as an inequality:

$0$

Drupady [299]

we are given

The population of Yuba city, California is 60,360 people

we know that

60360 lies between 60000 and 61000

but we always choose closer value

we can see that

60000 is more close to 60360 than 61000

so, nearest thousand will be 60000.................Answer

IN THE LAST TWO WEEKS , A PLANT GREW 1/16 IN. AND 3/16 IN. RESPECTIVELY

grandymaker [24]

I'm assuming you mean that the plant grew 1/16th of an inch the first week, and 3/16th of an inch the next week. Simply add the two together (4/16th) and simplify. Since four goes into both numbers, the simplified version is 1/4th. Hope this helps
