What’s 8x squared + 4 in vertex form

Mathematics

expression  8x squared + 4  or , 8x^2+4 in the vertex form is  8(x+0)^2+4 .

<u>Step-by-step explanation:</u>

Here we have , to convert expression  8x squared + 4  or , 8x^2+4 in the vertex form . Let's find out:

Let  y=8x^2+4 ,

⇒   y=8x^2+0(x)+4

Comparing this equation with y = ax^2+bx+c we get ;

a=8\\b=0\\c=4

Now , We know that  the vertex form of a parabola is ;

⇒ a(x+d)^2+e     ............(1)

Substitute the values of  a  and  b  into the formula d =\frac{b}{2a}

⇒ d=\frac{0}{2(8)} =0

Now , Value of e is ;

⇒ e= c- \frac{b^2}{4a}

⇒ e=4

Putting value of a, d ,e in equation (1) we get ;

⇒ a(x+d)^2+e  

⇒ 8(x+0)^2+4

Therefore ,  expression  8x squared + 4  or , 8x^2+4 in the vertex form is  8(x+0)^2+4 .

Sauron [17]
The answer would be 5547
First you multiply 5417 and 2.4% to get 130.008
Then you add 130.008 and 5417 to get 5547.008
but you can round this to 5547

A certain television is advertised as a 53-inch TV (the diagonal length). If the width of
zhenek [66]

The TV is 45 inches tall.

Step-by-step explanation:

The diagonal length of television = 53 inches

Width of TV = 28 inches

As TV is in rectangular or square shape, a diagonal will form a right triangle

Where,

Diagonal = hypotenuse = c = 53 inches

Width = base = b = 28 inches

Length = perpendicular = a

we will use pythagorean theorem to find the length.

a^2+b^2=c^2\\a^2+(28)^2=(53)^2\\a^2+784=2809\\a^2=2809-784\\a^2=2025

Taking square root on both sides

\sqrt{a^2}=\sqrt{2025}\\a=45

The TV is 45 inches tall.
