Question : A square game board is divided into smaller squares, each with sides one-ninth the length of the sides of the board.

bagirrra123 [75]

Answer:

Therefore the game board is divided into 81 smaller squares.

Step-by-step explanation:

Given that, there is a square game.

Consider x be length of one side the square.

The volume of the square is = side ×side

=x² square units

Since the length of side of smaller square is one-ninth of the game board.

Then one side length of the smaller square is $\frac19x$ units.

The area of a smaller square is $=(\frac19x)\times (\frac19x)$

$=\frac{1}{81}x^2$

Let a number of square is formed from the game board.

a ×The area of one smaller square= The area of game board.

According to the problem,

$a\times (\frac{1}{81}x^2)=x^2$

$\Rightarrow a =\frac{x^2\times 81}{x^2}$

$\Rightarrow a= 81$

Therefore the game board is divided into 81 smaller squares.

An acute angle θ is in a right triangle with sin θ = six sevenths. What is the value of cot θ?

inysia [295]

$\sin \theta =\dfrac{6}{7}\\
\cot \theta=\dfrac{x}{6}\\
x^2+6^2=7^2\\
x^2=49-36\\
x^2=13\\
x=\sqrt{13}\\
\boxed{\cot \theta =\dfrac{\sqrt{13}}{6}}$

The graph of a linear function passes through the point (-1, 2) and has a slope of 3. What is the equation of the function in sl

Harman [31]

Answer:

The equation of the function in slope-intercept form is y = 3 x + 5 .

Step-by-step explanation:

Given as :

A line passes through the point ( - 1 , 2 )

i.e ( x , y ) = ( - 1 , 2 )

The slope of the line is 3

The equation of line in slope intercept form

y - $\textrm y_1$ = m ( x - $\textrm x_1$ )

Where m is the slope of the line

So, y - 2 = 3 ( x - ( - 1 ) )

Or, y - 2 = 3 ( x + 1 )

Or, y - 2 = 3 x + 3

Or, y = 3 x + 3 + 2

∴ y = 3 x + 5

Hence The equation of the function in slope-intercept form is y = 3 x + 5 . Answer
