Since a log graph is with base 10 and a ln graph is with base e (2.something), the log x graph will clearly have smaller numbers (as, for example, log100=2 and ln100=around 4.6). In addition, you only have to multiply a number by e to increase the power by 1 but you have to multiply a number by 10 (which is significantly larger than e) to increase logx's power by 1, therefore proving that the log x graph will grow slower

Ivahew [28]

Answer:

Job A pay <u>$25</u> than Job B.

Step-by-step explanation:

Given:

Job A -Sales- offers a base salary of $1,000 per week plus 3% commission on all sales above $3000.

Job B -Sales- offers a base salary of $1,100 per week plus 2.5% commission on all sales above $3000.

The total sales for the week equal $25,000.

Now, to find how much more money Job A pay than Job B.

Total sales = $25,000.

Job A pay:

Base salary = $1,000.

Base salary plus 3% commission on $25000.

$1000 + 3% of $25000.

= $1000+\frac{3}{100}\times 25000$

$=1000+0.03\times 25000$

$=1000+750$

$=1750.$

Job A pay = $1750.

Now,

Job B pay:

Base salary = $1,100.

Base salary plus 2.5% commission on $25000.

$1,100 + 2.5% of $25,000.

$=1100+\frac{2.5}{100}\times 25000$

$=1100+0.025\times 25000$

$=1100+625$

$=1725$

Job B pay = $1725

So, by deducting the salary of Job B from Job A we get the more amount:

$1750-1725\\=25$

Therefore, Job A pay $25 than Job B.

HELP!!!!! 50 POINTS!!

Law Incorporation [45]

Basically here all you want to do it substitute the values x=1 and x=2 for the given function. Use your slope formula $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1} }$ .

Do same for x=3 and x=4

You next divide plug in values in to this expression:

$\frac{Slope of B}{Slope of A}$

The current in a stream moves at a rate of 7 mph. If a boat travels 98 miles downstream in the same time that it takes to travel

JulijaS [17]

If the current in a stream moves at a rate of 7 mph. If a boat travels 98 miles downstream in the same time that it takes to travel 49 miles upstream then the speed of the boat in still water is 21 miles per hour.

<h3>What is speed?</h3>

Speed is the distance covered by an object in a certain time period. It is also known as velocity. The formula of speed is as follows:

Speed=Distance/ Time.

<h3>How to calculate speed?</h3>

We have been given that the speed of stream is 7miles per hour.

Let v be the speed of the boat, and t the time to travel

98=t*(7+v) (1)

49=t(v-7) (2)

(1)+(2) => 2tv=147

7t+(49+7t)=98

14t+49=98

14t=49

t=49/14

t=7/2

Put the value of t in equation 1 to get the value of v:

98=t(7+v)

98=7/2(7+v)

196/7=7+v

28=7+v

v=28-7

v=21

Hence if the current in a stream moves at a rate of 7 mph. If a boat travels 98 miles downstream in the same time that it takes to travel 49 miles upstream then the speed of the boat in still water is 21 miles per hour.
