consider the polynomial 2/3x (2x-3) - (x-7) (x+7) when simplified, what is the coefficent of the quadratic term?
Svet_ta [14]

Answer:

x^2 - 6x + 147 so the coefficient is 1

Step-by-step explanation:

First, simplify the equation.

1. 2/3x(2x-3) = (2x/3)(2x-3)-(x-7)(x+7)

2. 2x-3(2x/3) = (2x(2x-3)) - (x-7)(x+7)

3. Expand -(x-7)(x+7) = -x^2+49

Combine to get (x^2 - 6x)/3 +49

Simplify to get x^2 - 6x + 147. The coefficient of the quadratic term is one.

Find the x- and y-intercepts of the parabola y=x2+10x+4
Nuetrik [128]

Answer:

x-intercepts: -5 +/-\sqrt{21}. y-intercept: 4

Step-by-step explanation:

For x-intercepts use the quadratic equation

x= (-b +/-\sqrt{b^2-4ac} )/2a

Fill in your values:

x= (-10 +/-\sqrt{100-16} )/2

And solve

x=-5 +/- \sqrt{21}

For y-intercepts set x=0 and solve. In this case, setting x= 0 gives you y=4.

Rearrange the formula A = \pi r ^ ( 2) for r
tatyana61 [14]
Consider re-writing this formula as "A = pi*r^2."  The backslash symbol "\" is unnecessary.

If A = pi*r^2, and we wish to solve for r, then divide both sides by pi:

A/pi = r^2

Taking the square root of both sides,   sqrt(A/pi) = r (r must be positive in this situation).

Endure all, a manufacturer of batteries claims that the lifetime of their batteries is normally distributed with a mean of 500 h
ycow [4]

Based on the z-score, an Endure All battery selected at random has a 10.56% chance of lasting more than 550 hours.

<h3>What are z-scores?</h3>

How closely a value relates to the mean of a set of values is expressed by a Z-score.

The Z-score is created using standard deviations from the mean.

A data point's total value is equal to the mean value when the Z-score of the data point is equal to 0.

So, in order to determine how far the raw score deviates from the mean, the Z score is used.

The following steps are used to determine the Z score:

z = (x - μ)/σ

We know that:  x > 550 and μ = 500, σ = 40

z = 550 - 500 / 40

z = 1.25

The graph of the normal distribution indicates:

P(z > 1.25) = 1 - P(z < 1.25)

P(z > 1.25) = 1 - 0.8944

P(z > 1.25) = 0.1056

Therefore, based on the z-score, an Endure All battery selected at random has a 10.56% chance of lasting more than 550 hours.
