2x + (6/(4x)) - 8 = 2x + 2(3/(2x)) - 8  => excluded value is 0
<span>(2x + 6)/(4x - 8) = [2(x+3)]/[4(x-2)] = (x+3)/[2(x-2)] => excluded value is 2</span>

sweet-ann [11.9K]

Answer:

17.74%

Step-by-step explanation:

The formula for percent error is given as:

|Estimated value - Actual value|/Actual value × 100

From the above question:

Estimated value = 73 feet

Actual value = 62 feet

Hence,

Percent error = |73 - 62|/62 × 100

= 11/62 × 100

= 17.741935484%

Approximately , percent error = 17.74%

Therefore, the percent error of Andy's estimation is 17.74%

Which is the standard form of the equation of the parabola that has a vertex of (3, 1) and a directric of x = -2?
vagabundo [1.1K]
Check the picture below.  So,the parabola looks like so, notice the distance "p". since the parabola is opening to the right, then "p" is positive, thus is 5.

\bf \textit{parabola vertex form with focus point distance}\\\\&#10;\begin{array}{llll}&#10;\boxed{(y-{{ k}})^2=4{{ p}}(x-{{ h}})} \\\\&#10;(x-{{ h}})^2=4{{ p}}(y-{{ k}}) \\&#10;\end{array}&#10;\qquad &#10;\begin{array}{llll}&#10;vertex\ ({{ h}},{{ k}})\\\\&#10;{{ p}}=\textit{distance from vertex to }\\&#10;\qquad \textit{ focus or directrix}&#10;\end{array}\\\\

\bf -------------------------------\\\\&#10;\begin{cases}&#10;h=3\\&#10;k=1\\&#10;p=5&#10;\end{cases}\implies (y-1)^2=4(5)(x-3)\implies (y-1)^2=20(x-3)&#10;\\\\\\&#10;\cfrac{1}{20}(y-1)^2=x-3\implies \boxed{\cfrac{1}{20}(y-1)^2+3=x}
