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}}\\&#10;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 &#10;\begin{cases}&#10;h=0\\&#10;k=1\\&#10;when&#10;\\&#10;x=\pm 1\\&#10;y=0&#10;\end{cases}&#10;\\\\\\&#10;\textit{so.. hmmm let us use the point ... say hmmm 1,0}&#10;\\\\&#10;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
