Step-by-step explanation:

<u>Step 1:  FOIL</u>

<u />(2x-4)(2x-3)

 1      2   3     4

Use these number below:

<u>Distribute</u>

<u />(2x *2x) + (2x*-3) + (-4*2x) + (-4*-3)

  1  * 3          1   *  4          2 * 3            2 * 4

(4x^2)+(-6x)+(-8x)+(12)

4x^2-14x+12

Answer:  4x^2-14x+12

HDTV screens usually have a width-to -height ratio of 16:9. Which screen dimensions are in the same proportion?
love history [14]

Answer:

4 feet by 3 feet

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

width-to -height ratio of 16:9

Let analyse all possible answers:

  • 4 feet by 3 feet

16 divided by 4 is the same as 9 divided by 3 => it is true

  • 28 inches by 21 inches

16 divided by 28 is different as 9 divided by 21 => it is wrong

  • 48 centimeters by 27 centimeters

16 divided by 48 is different as 9 divided by 27 => it is wrong

  • 26 inches by 19 inches

16 divided by 26 is different as 9 divided by 219=> it is wrong

We choose A.

Hope it will find you well.

Determine the vertical asymptote for the rational function f(x) = x - 4 over 2x - 3
k0ka [10]

Answer:

x = \frac{3}{2}

Step-by-step explanation:

Given

f(x) = \frac{x-4}{2x-3}

The denominator cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = \frac{3}{2}

Thus x = \frac{3}{2} is the vertical asymptote

A mother invests $7000 in a bank account at the time of her daughter's birth. The interest is 18) compounded quarterly at a rate
Alex

well, from birth to your twentieth birthday that'll just be 20 years, so

~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$7000\\ r=rate\to 8\%\to \frac{8}{100}\dotfill &0.08\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years\dotfill &20 \end{cases} \\\\\\ A=7000\left(1+\frac{0.08}{4}\right)^{4\cdot 20}\implies A=7000(1.02)^{80}\implies A\approx 34128.07
