Lins father is paying $20 for a meal. He has 15%-off coupon for the meal. After the discount, 7% sales tax is applied, How much

tankabanditka [31]

Answer: $18.19

Step-by-step explanation:

The tax is applied after the discount so first find the discounted price:

= Price * ( 1 - discount rate)

= 20 * ( 1 - 15%)

= $17

The sales tax of 7% can then be applied:

= Price * ( 1 + tax rate)

= 17 * ( 1 + 7%)

= $18.19

Which statements accurately describe the function f(x) = 3(StartRoot 18 EndRoot) Superscript x? Select three options. The domain

Studentka2010 [4]

Answer:

The domain is all real numbers.

The initial value is 3

The simplified base is $9\sqrt{2}$

Step-by-step explanation:

The given function is $f(x)=3(\sqrt{18})^x$ .

To find the initial value, we put x=0 into the function:

$f(0)=3(\sqrt{18})^0$ .

$f(0)=3(1)=3$ .

The initial value is actually 3.

The given function is an exponential function, therefore the domain is all real numbers.

The range of this function refers to all values of y for which the function is defined.

The line y=0, is the horizontal asymptote.

The range is $y\:>\:0$

The simplified base is $3\sqrt{18}=3\sqrt{9\times2}$ .

$3\sqrt{18}=3\sqrt{9}\times\sqrt{2}$

$3\sqrt{18}=3\times3\times\sqrt{2}$

$3\sqrt{18}=9\sqrt{2}$
