What’s 8x squared + 4 in vertex form

Mathematics
1 answer:
Nataly [62]3 years ago
7 0

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 .

Scorpion4ik [409]

Complete question :

Standardized tests: In a particular year, the mean score on the ACT test was 19.3 and the standard deviation was 5.3. The mean score on the SAT mathematics test was 532 and the standard deviation was 128. The distributions of both scores were approximately bell-shaped. Round the answers to at least two decimal places. Part: 0/4 Part 1 of 4 (a) Find the z-score for an ACT score of 26. The Z-score for an ACT score of 26 is

Answer:

1.26

Step-by-step explanation:

Given that:

For ACT:

Mean score, m = 19.3

Standard deviation, s = 5.3

Zscore for ACT score of 26;

Using the Zscore formula :

(x - mean) / standard deviation

x = 26

Zscore :

(26 - 19.3) / 5.3

= 6.7 / 5.3

= 1.2641509

= 1.26

Create a word problem that involves speed
lana66690 [7]

A hockey puck is sliding on frictionless ice on an infinite hockey rink.
Its speed is 36 km/hour.  How far does the puck slide in 10 seconds ? 

 (36 km/hr) x (1,000 m/km) x (1 hr/3600 sec) x (10sec) =

         (36 x 1,000 x 10 / 3,600) meters  =  <em>100 meters</em>

What is the puck's speed in miles per hour ?

        (36 km/hr) x (0.6214 mi/km)  =  <em>22.37 mi/hr</em>

What is the simplified form of the expression? k3 [k^7/3] -5
iragen [17]
Simplify the following:
(k^3 k^7)/3 - 5

Combine powers. (k^3 k^7)/3 = k^(7 + 3)/3:
k^(7 + 3)/3 - 5

7 + 3 = 10:
k^10/3 - 5

Put each term in k^10/3 - 5 over the common denominator 3: k^10/3 - 5 = k^10/3 - 15/3:
k^10/3 - 15/3

k^10/3 - 15/3 = (k^10 - 15)/3:
Answer: (k^10 - 15)/3
