Answer:

$124$

Step-by-step explanation:

$6 {x}^{2} +10x−1$

The discriminant of a quadratic is the expression inside the radical of the quadratic formula.

${b}^{2} −4(ac)$

Substitute in the values of a, b, and c.

${10}^{2} −4(6 \times (−1))$

$100−4(6(−1)$

$100−4(−6)$

$100 + 24$

$124$

the result of an experiment was 117.755 particles per milliliter. write the decimal as a mixed number.

The result of experiment in mixed fraction form is $117\frac{151}{200}$ particles per milliliter.

<h3>What is the result of the experiment in mixed fraction form?</h3>

To convert decimal to fraction, we the decimal number over 1 and multiply both the numerator and denominator by power of 10.

Given the data in the question;

Result of experiment in decimal form = 117.755
Result of experiment in mixed fraction form = ?

In 117.755, we have 3 numbers to the right of the decimal point.

We have 10³ which is the same as 1000.

$\frac{117.755}{1} * \frac{1000}{1000}\\\\\frac{117755}{1000}$

Next, we divide both the numerator and the denominator with their Greatest Common Factor.

Greatest Common Factor of 117755 and 1000 is 5

$\frac{\frac{117755}{5} }{\frac{1000}{5} } = \frac{23551}{200}$

Now, we can get 200 out of 23551 exactly 117 times, since what remained is not divisible by 200, we leave it as a remainder [151].

We can now write this in a mixed fraction form as;

$117\frac{151}{200}$

Therefore, the result of experiment in mixed fraction form is $117\frac{151}{200}$ particles per milliliter.

The rational function has a y-intercept of 7. What is the equation for this function?

Schach [20]

Answer:

$\large\boxed{f(x)=\dfrac{4}{x+2}+5}$

Step-by-step explanation:

$f(x)=\dfrac{a}{x-b}+c\\\\\text{We have}\\\text{(1) the vertical asymptote}\ x=-2.\ \text{Therefore}\ b=-2.\\\text{(2) the horizontal asymptote}\ y=5.\ \text{Therefore}\ c=5.\\\text{(3) the point (0, 7). Put the coordinates of the point to the equation}\\\text{of the function}\\y=\dfrac{a}{x-(-2)}+5\\\\7=\dfrac{a}{0+2}+5\qquad\text{subtract 5 from both sides}\\\\2=\dfrac{a}{2}\qquad\text{multiply both sides by 2}\\\\4=a\to a=4\\\\\text{Finally:}\\\\f(x)=\dfrac{4}{x+2}+5$
