Lateral surface area = (23×12.04)+(23×8)+(23×9)
= 276.92 + 184 + 207
=667.92
= 668m²

Total surface area = 668 + 1/2(2×8×9)
= 668 + 72
= 740m²

The C(x) equation is a parabola with a squared "x" and a positive leading term coefficient, meaning, is a vertical parabola and it opens upwards

the lowest point, or lowest cost value, it reaches, is the U-turn point, or vertex

$\bf \textit{ vertex of a vertical parabola, using coefficients}\\\\
\begin{array}{llccll}
y = &{{ 1}}x^2&{{ -320}}x&{{ +40052}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)$

so, the lowest cost is at $\bf {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}$

A garden is 4 yards 24 inches wide and 6 yards long. Write the ratio of the width to the length as a fraction in simplest form.

Mnenie [13.5K]

we have

4 yards 24 inches wide

6 yards long

step 1

convert inches to yards

we know that

1 yard is equal to 36 inches

24 inches=(24/36)=2/3 yards

4 yards 24 inches wide=4+(2/3)=14/3 yards

step 2

Find the ratio

W/L=(14/3)/(6)=14/18=7/9

therefore

the answer is

the ratio is equal to (7/9)
