The area of a rectangle, A = l • w is represented by the expression 24x^6y^15. Which could be the dimensions of the rectangle?
NeX [460]

After calculating the value, l & w could be 2x^{5} y^{8} & 12x^{} y^{7}.

<h3>Calculation:</h3>

The inquiry relates to the laws of indices

where, x^{a} * x^{b}=x^{a+b}

Provided the query, A= 24x^{6}y^{15}

2* 12 might be used to calculate the length and width of 24.

Hence,

x^{6}=x^{5} * x^{1} =x^{5+1}

& y^{15}= y^{8} * y^{7} =y^{8+7}

So, it can be written as,

A=l * w

⇒ 24x^{6}y^{15} = 2x^{5}y^{8} * 12xy^{7}

Therefore, it is concluded that the dimensions of the rectangle could be 2x^{5} y^{8} & 12x^{} y^{7}.

It is: THE SUM OF THREE CONSECUTIVE NUMBERS IS 78 WHAT IS THE SMALLEST OF THREE NUMBERS?
TiliK225 [7]
-----------------------------------------------
Define x :
-----------------------------------------------
Let the smallest number be x.
The other two numbers will be x+1 and x+2.

-----------------------------------------------
Construct equation :
-----------------------------------------------
The sum of all 3 numbers is 78
⇒ x + x + 1 + x + 2 = 78

-----------------------------------------------
Solve x :
-----------------------------------------------
x + x + 1 + x + 2 = 78
3x + 3 = 78
3x = 78 - 3
3x = 75
x = 25

-----------------------------------------------
Answer: Smallest number = 25

If sin 0 = 7/25, find csc 0
kipiarov [429]

Answer:

csc(\theta)=\frac{25}{7}

Step-by-step explanation:

We know that:

sin(\theta)=\frac{7}{25}

And we want to find:

csc(\theta)

Remember that there is a trigonometric identity that relates the sin(\theta) function with the csc(\theta) function

csc(\theta)=\frac{1}{sin(\theta)}

Then if sin(\theta)=\frac{7}{25} this means that:

csc(\theta)=\frac{1}{\frac{7}{25}}

Finally:

csc(\theta)=\frac{25}{7}
