Find the difference quotient of the exponential function, f(x) = e^x

Orlov [11]

Answer:

Step-by-step explanation:

The difference quotient in general looks like

$\frac{f(x+h)-f(x)}{h}$ Sometimes the symbol "delta x" $\Delta x$ is used instead of h.

For the exponential function, the difference quotient is

$\frac{e^{x+h}-e^x}{h}$

PLEASE help with these math questions

SIZIF [17.4K]

Questions 1, 2, 3, and 4 are exercises to give you practice with
common denominators. For each of these questions, change all
the fractions to common denominators, and the answers jump out at you.

#1). 5/12 = 25/60
   2/5 = 24/60
Make um negative, and then you'll have the answer right away.

#2). The one that's negative is obviously the least.
Both positive ones must be bigger than the negative one.
For the positive ones:

   2/5 = 6/15
   2/3 = 10/15 .
Now it's easy.

#3). This is tough. The least common denominator is 2,520 !
It's probably easier to just do the divisions and get the decimals
for each fraction.

   -5/8 = -0.625
   -7/9 = -0.777...
   -4/5 = -0.8
   -3/7 = -0.428...
Now it's easy to line um up.

#4). Sneaky one.
Look closely at each fraction.
B, C, and D are all less than 1, so they're not between 1 and anything more than 1.
8/5 is the only one that's more than 1.

#5). A fraction is just a short way to write a division problem.
When you see a fraction, it means

   "the top number divided by the bottom number" .

When you actually do the division, the quotient you get
is the decimal form of the fraction.

To change a decimal into a percent,
move the decimal point two places that way ==> .

The numbers in the boxes at the bottom of #5 are the correct numbers,
but they both should be negative. (because the -3/8 is negative)

What is the third quartile of this data set? 20, 21, 24, 25, 28, 29, 35, 37, 42

nata0808 [166]

Answer:

Step-by-step explanation:

⇒The question is on third quartile

⇒To find the third quartile we calculate the median of the upper half of the data

Arrange the data in an increasing order

20, 21, 24, 25, 28, 29, 35, 37, 42

Locate the median, the center value

20, 21, 24, 25, 28, 29, 35, 37, 42

The values 20, 21, 24, 25 ------------lower half used in finding first quartile Q1

The value 28 is the median

The vlaues 29, 35, 37, 42...............upper half used in finding 3rd quartile Q3

Finding third quartile Q3= median of the upper half

upper half= 29,35,37,42

median =( 35+37)/2 = 36
