Travis wants to solve a quadratic equation. Since his equation cannot be factored, Travis has to graph the equation and approxim
SOVA2 [1]

Answer:

The correct answer is B.

Step-by-step explanation:

In order to find this, calculate out the discriminant for each of the following equations. If the discriminant is a perfect square, then it can be factored.

Discriminant = b^2 - 4ac

The only of the equations that does not yield a perfect square is B. The work for it is done below for you.

Discriminant = b^2 - 4ac

Discriminant = 7^2 - 4(2)(-5)

Discriminant = 49 + 40

Discriminant = 89

Since 89 is not a perfect square, we cannot factor this.

What values for x would make the lines parallel?
Svetllana [295]

Answer:

x = 15  degrees

3 angles in triangle are 44, 44 and 92 degrees.


Step-by-step explanation:

When the lines are parallel the internal angles add up to 180 degrees. So:-

8x + 7 + 2x + 23 = 180

10x + 30 = 180

10x = 150

x = 15


In the triangle:-

The angle adjacent to 136 = 180 - 136

= 44 degrees.  As 2 sides of the triangle are congruent the other base angle = 44 degrees also.

The third angle = 180 - 2(44) =  92 degrees

Rainbow [258]

Answer:

The stock price beyond which 0.05 of the distribution fall is $12.44.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Mean of $8.52 with a standard deviation of $2.38

This means that \mu = 8.52, \sigma = 2.38

The stock price beyond which 0.05 of the distribution fall is

This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.

Z = \frac{X - \mu}{\sigma}

1.645 = \frac{X - 8.52}{2.38}

X - 8.52 = 1.645*2.38

X = 12.44

The stock price beyond which 0.05 of the distribution fall is $12.44.

F(x)=x^3+4x^2+x-6<br> What are the real zeros
Over [174]

Happy New Year from MrBillDoesMath!

Answer:

   1, -2, -3

Discussion:

The real roots of the polynomials are factors of the last term (6) divided by the first term (1). The factors of 6/1 or 6 are 1,2,3, and 6. I found by substitution that x= 1 was a solution, divided the polynomial by x-1, came up with a quadratic (x^2 + 5x + 6), and found the remaining roots via the quadratic formula.


Thank you,

MrB
