STALIN [3.7K]

Explanation:

1. The general form of a quadratic in standard form* is ...

$f(x)=ax^2+bx+c$

An example is ...

$f(x)=2x^2+3x-5$

The constant c is the y-intercept, so is the easiest bit of information to obtain in this form.

2. The general form of a quadratic in vertex form can be written as ...

$f(x)=a(x-h)^2+k$

An example is ...

$f(x)=2(x -3)^2 -5$

The ordered pair (h, k) is the vertex of the parabola, so is easy to obtain in this form. Arguably, it may be easier to identify the line of symmetry, x=h, since that requires looking at only one constant, instead of two.

_____

* In the UK, "standard form" is vertex form.

a plane took 3 hours and 33 minutes to finish a journey. if the distance of the journey was 2840 miles, at what average speed di

likoan [24]

Answer:

The average speed of the plain was 800 miles/h.

Step-by-step explanation:

To solve this problem we first need to convert the time the tain took to finish the journey to hours. To do that we will divide the part that is in minutes by 60 and sum to the part that is in hours, we have:

time = 3 + 33/60 = 3 + 0.55 = 3.55 hours

The average speed is given by the following formula:

average speed = distance/time

average speed = 2840/3.55 = 800 miles/h

The average speed of the plain was 800 miles/h.

Help!!!!!!!!!!!!!!! A square tabletop has side lengths of (4x − 8) units. Enter a polynomial that represents the area of the tab

kherson [118]

Answer: $16x^{2}-64x+64$

Step-by-step explanation:

1. The formula for calculate th area of a square is shown below:

$A=s^{2}$

Where s is the side of the square.

2. Therefore, if the square tabletop has side lengths of (4x-8) units you have:

$(4x-8)^{2}$

3. By definition, the square of a binomial is always a trinomial:

$(a-b)^{2}=a^{2}-2ab+b^{2}$

4. Then, you obtain:

$(4x-8)^{2}=(4x)^{2}-2(4x)(-8)+8^{2}=16x^{2}-64x+64$

A spinner is divided into six equal-sized sectors labeled 1 through 6. Dwayne spins this spinner 12 times. Let X

slavikrds [6]

Answer:

b) μ = 2 and σ = 1.29

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6</em>

<em>Given that the probability of labelled '1'</em>

<em> </em> $p = \frac{1}{6}$ =0.16

<em> q = 1-p = 1- 0.16 = 0.84</em>

Let 'X' be a random variable in binomial distribution

The mean of the binomial distribution

μ = n p

μ = $12 (\frac{1}{6} ) = 2$

<em>The mean of the binomial distribution = 2</em>

<u><em>Step(ii):-</em></u>

The standard deviation of X

σ $= \sqrt{npq}$

σ = $\sqrt{12(0.16)(0.84}$

σ = $1.269$

<em>The standard deviation of the binomial distribution</em>

<em> </em> σ = $1.269$

<u><em></em></u>
