Explain the process of changing rational exponents to radical form

hoa [83]

The formula that describes the transformation of rational exponents to radical form is:

$a^{\frac{n}{m}} = \sqrt[m]{a^n}$

<h3>Transformation of rational exponents to radical form:</h3>

A rational exponent is represented by: $a^\frac{m}{n}$ .

That is, the exponent is a fraction, in which m is the numerator and n is the denominator.

In the conversion to radical form, the numerator will be power(also exponent), while the denominator will be the root.

Hence, the formula for the transformation is:

$a^{\frac{n}{m}} = \sqrt[m]{a^n}$

Vertex (0,1) x intercepts is - 1 and 1 what is the equation of the parabola?

MrRa [10]

$\bf y=a(x-{{ h}})^2+{{ k}}\\
x=a(y-{{ k}})^2+{{ h}}\qquad\qquad vertex\ ({{ h}},{{ k}})$

those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below

that means, the squared variable is the "x", thus the form is $\bf y=a(x-{{ h}})^2+{{ k}}$

now, we know the vertex is at 0,1, and two x-intercepts of $\pm 1,0$

thus $\bf y=a(x-{{ h}})^2+{{ k}}\qquad 
\begin{cases}
h=0\\
k=1\\
when
\\
x=\pm 1\\
y=0
\end{cases}
\\\\\\
\textit{so.. hmmm let us use the point ... say hmmm 1,0}
\\\\
y=a(x-{{ h}})^2+{{ k}}\implies 0=a(1-0)^2+1$

solve for "a", to see what that coefficient is, then plug it back in the vertex form equation

When Rashaad goes bowling, his scores are normally distributed with a mean of 175

nikdorinn [45]

Answer:

The interval (162, 188)would represent the middle 68% of the scores of all the games that Rashaad bowls.

Step-by-step explanation:

As per the empirical rule of normal distribution, for any normally distributed curve, the values lie between the extreme values i.e

(μ - σ) and (μ + σ).

Given

μ = 175

σ = 13

(μ - σ) = 175 -13 = 162

(μ + σ) = 175 + 13 = 188

Hence the required interval is 162, 188
