Answer:

120 ways

Step-by-step explanation:

The question here says that there are 5 different robots and we want to arrange them all in a line. How many different ways are thereto arrange them?

---Total number of robots is 5 and since we are dealing with the arrangements without order,then we are talking about combinations

And since the arrangements requires them to be lined up in a single line, we are going to work this out without much stress.

5! ÷ 1! = 5 × 4 × 3 × 2 × 1 ÷ 1

= 120 ways

ABCD is a rectangle. if AC = 3y/5 anf BD= 3(y-4), find the length of each diagonal

Digiron [165]

Remember please that Diagonals of a Rectangle are equal to each other:<span> 3y/5 = 3(y-4)
So
</span><span>3y = 15(y-4)
3y = 15y - 60
60 = 12y
y = 5 Diagonals are both 3 units
With that you will be able to know which is the answer from your options</span>

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

Umnica [9.8K]

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