What is the total surface area of the box formed by the pattern below

nadezda [96]

Answer:

<h2>The total surface area of the box is 224 square inches.</h2>

Step-by-step explanation:

The box pattern is shown in the image attached.

The total surface is the sum of the area of each section of the figure, which is formed by 4 equal rectangles and 2 equal squares. Rectangles have dimensions of 12 inches by 4 inches, and squares have 4 inches per side.

So, the total surface would be

$S_{total}=S_{squares} +S_{rectangles}\\ S_{total}=2(4in)^{2} +4(12in \times 4 in)\\ S_{total}=2(16in^{2})+4(48in^{2} ) \\ S_{total}=32in^{2}+192in^{2}\\ S_{total}=224in^{2}$

Therefore, the total surface area of the box is 224 square inches.

Given that tan 0=-4/7 , and 270 degrees <0<360 degrees , what is the exact value of sec0?

Elanso [62]

I take it you meant θ angle, anyway.

we know the tan(θ) = -4/7... alrite, we also know that 270° < θ < 360°, which is another to say that θ is in the IV quadrant, where the adjacent side or "x" value is positive whilst the opposite side or "y" value is negative.

$\bf tan(\theta )=\cfrac{\stackrel{opposite}{-4}}{\stackrel{adjacent}{7}}\impliedby \textit{now let's find the \underline{hypotenuse}}
\\\\\\
\textit{using the pythagorean theorem}
\\\\
c^2=a^2+b^2\implies c=\sqrt{a^2+b^2}
\qquad 
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
\end{cases}
\\\\\\
c=\sqrt{7^2+(-4)^2}\implies \implies c=\sqrt{65}\\\\
-------------------------------\\\\
sec(\theta )=\cfrac{\stackrel{hypotenuse}{\sqrt{65}}}{\stackrel{adjacent}{7}}$
