Tell whether the two quantities vary directly. Explain your reasoning. The cafeteria provides three meals per day.
Dafna11 [192]

Answer:

The cafeteria provides three meals per day.

<u>Reason 1</u>

Yes, they vary directly  

As number of days increases ,Total number of meals i.e

1st day ⇒ 3

2nd day⇒6

3 rd day⇒9

4th day⇒12

......................

.........................

increases.

Total number of Meals = k×Number of days

But there is another possibility also

<u>Reason 2</u>

1 st day ⇒ 3

2nd day ⇒3

3rd day⇒ 3

.....................

.....................

As you can see from the above expression On each day number of meals is  

constant.

So we can say that ,

On each Day=Constant amount of meal=3

So, there is no Proportionality between Days and Meal.

What is pi squared as a fraction?
ivolga24 [154]
Π=3.14
Let's start with two digits:

3.14 = 3 14/100

= 3 7/50

= 157/50

would be the approximation for that. Let's add a few more digits:

3.1415 = 3 1415/10000

= 3 283/2000

= 6283/2000

The volume of a cube can be found using the equation V = s³, where V is the volume and s is the measure of one side of the cube.
Arte-miy333 [17]

\bf \textit{volume of a cube}\\\\&#10;V=s^3~~&#10;\begin{cases}&#10;s=side\\[-0.5em]&#10;\hrulefill\\&#10;V=1833&#10;\end{cases}\implies 1833=s^3\implies \sqrt[3]{1833}=s\implies 12.238292\approx s

(1+tan^2 A)cot A/cosec^2 A= tanA​
Rufina [12.5K]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

1 + tan²A = sec²A , secA = \frac{1}{cosA}, cosecA = \frac{1}{sinA} , cotA = \frac{cosA}{sinA} , tanA = \frac{sinA}{cosA}

Consider the left side

\frac{(1+tan^2A)cotA}{cosec^2A}

= \frac{sec^2AcotA}{cosec^2A}

= \frac{\frac{1}{cos^2A}(\frac{cosA}{sinA})  }{cosec^2A}

= \frac{\frac{1}{cosAsinA} }{\frac{1}{sin^2A} }

= \frac{1}{cosAsinA} × sin²A

= \frac{sinA}{cosA}

= tanA = right side , thus proven
