List price is $600.25, the rate of discount is 20%, what is the net price

Bumek [7]

First, convert the 20% to a real mathematical number. For percents, this is always done by dividing the 20% by 100%, or 20% / 100% = 0.200.

Second, find out what 20% of $600.25 is. This is the amount of the sale discount. This is always found by mulitplying 0.200 by the item's cost $600.25, like this:

0.200 x $600.25 = $120.05.

So for this sale, you'll save $120.05 on this item.

This means, the cost of the item to you is

$600.25 - $120.05 = $480.20.

Alternatively, you can think about it this way. The item is 20% off. This means you'll pay 80.000% of the total cost (100% - 20% = 80.000%).

Now what's 80.000% of the total cost?

0.800 x $600.25 = $480.20.

Just like the result above, the sale price on the item is $480.20.

Hope this helps you on your assignment! :)

Which of the following equations is equivalent to 2log4x − log49 = 2?

Masja [62]

Answer:

The value of x for given log equation is 17. 5

Step-by-step explanation:

Given as :

The log function is

2 log 4 x - log 49 = 2

Or, 2 log 4 x - log (7 × 7) = 2

Or, 2 log 4 x - log 7² = 2

from Log property

$Loga^{b}$ = b Log a

So, 2 log 4 x - 2 log 7 = 2

Taking 2 from Left hand side of equation

Or, 2 × (log 4 x - log 7) = 2

Or, (log 4 x - log 7) = $\dfrac{2}{2}$

Or, (log 4 x - log 7) = 1

Again from Log property

Log m - Log n = Log $\dfrac{m}{n}$

So, (log 4 x - log 7) = 1

Or, Log $\dfrac{4 x}{7}$ = 1

Now, Taking anti Log , we get

So, $\dfrac{4 x}{7}$ = antilog 1

i.e $\dfrac{4 x}{7}$ = $10^{1}$

Or, 4 × x = 10 × 7

∴ x = $\dfrac{70}{4}$

Or, x = 17.5

So, The value of x = 17.5

Hence, The value of x for given log equation is 17. 5 Answer

What is the inverse of the logarithmic function f(x) = log9x?

borishaifa [10]

Answer: The inverse of the logarithmic function will be

$f^{-1}(x)=9^x$

Step-by-step explanation:

Since we have given that

$f(x)=\log_9(x)$

Replace f(x) with y.

$y=\log_9(x)$

Now, interchanging with variables:

$x=\log_9(y)$

$\implies y=9^x$

Now, again put y = f(x).

So, it becomes,

$f(x)=9^x$

Hence, the inverse of the logarithmic function will be

$f^{-1}(x)=9^x$
