Answer:

a × a × a ×a

Step-by-step explanation:

Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor.

Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.

square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches.

What is the vertex of the graph of f(x) = |x – 13| + 11?

dybincka [34]

Answer:

The vertex of the graph of f(x) = |x - 13| + 11 is (13, 11).

Step-by-step explanation:

There is something called absolute value in the given function. It means two equations will result from it.

When $(x -13) > 0$ the resultant equation is

$y = f(x) = x - 13 + 11 = x - 2$ - This will be the first equation

When $(x - 13) < 0$ the resultant equation is

$y = f(x) = -(x - 13) + 11 = -x + 24$ - This will be the second equation.

The intersection of these lines will give the vertex as found by solving both equations at the same time.

$y = x - 2$

$y = -x + 24$

_________

$2y = 0 + 22$

$y = \frac{22}{2} = 11$

Replacing the value of $y$ for any one;

$x = 11 + 2 = 13$ (first one)

$x = 24 - 11 = 13$ (second one)

The vertex is (13, 11)

Answer:

What's the question here?

Step-by-step explanation:

The weight of the 1st bag is independent from the airline weight specification given. If the max weight of 65kg is given, this means that she/he can take on board (including the luggage) a maximum of 65kg. Does not include human weight

PLEASE can someone explain why The exact value of sec ( π/6) is 2 /√ 3 ??

Umnica [9.8K]

$\bf sec\left( \frac{\pi }{6} \right)\qquad recall\to sec(\theta)=\cfrac{1}{cos(\theta)}\qquad thus
\\\\
sec\left( \frac{\pi }{6}\right)\iff \cfrac{1}{cos\left( \frac{\pi }{6}\right)}
\\\\\\
\textit{check your Unit Circle for what the }cos\left( \frac{\pi }{6}\right)\ is
\\\\\\
\cfrac{1}{\frac{\sqrt{3}}{2}}\implies \cfrac{\frac{1}{1}}{\frac{\sqrt{3}}{2}}\implies 
\cfrac{1}{1}\cdot \cfrac{2}{\sqrt{3}}\implies \cfrac{2}{\sqrt{3}}$
