25 x^2 - 100 y^2

= 25 (x^2 - 4y^2)

=25 (x^2 - (2y)^2)

=25(x - 2y)(x+2y)

We can distribute the 25 however we like; the choices multiply each factor by five.

= (5x -10y)(5x+10y)

Choice D

A sinusoidal function whose frequency is 1/6pi
Lyrx [107]

Answer:

B. f(x)=9\sin (\frac{x}{3})+3

Step-by-step explanation:

We are given that,

The frequency of the function is \frac{1}{6\pi}

The maximum and minimum value is 12 and -6.

Also, the y-intercept is 3.

From the options, we have,

Options C and D have minimum value 6. So, they does not represent the given function.

We know, 'If a function has a period P, then the function a+f(bx+c) will have the period \frac{P}{|b|}.

Also, 'The frequency is the reciprocal of the period'.

So, function a+f(bx+c) will have the frequency \frac{|b|}{P}.

From the options, we see,

Option B have the frequency, \frac{\frac{1}{3}}{2\pi} i.e. \frac{1}{6\pi}.

Option A have the frequency, \frac{6\pi}{2\pi} i.e. 3

Thus, option A is not correct.

Hence, option B is the required sinusoidal function.

An architect plans to make a drawing of the room of a house. The segment LM represents the ceiling of the room. He wants to cons
aev [14]
Here are the steps

1: Put the compass on Q and make the width equal to the distance from Q to L. Extend line LM towards the left side of L and draw an arc hitting the line segment on the left side of L

2. <span> Without changing the width and position of the compass, draw an arc between L and M.

3. Without changing the width of the compass, put the compass on the point of intersection of the arc and line LM (left side of L). Draw an arc above line LM.

4. Without changing the width of the compass, put the compass on the point of intersection of the arc and line LM (right side of L). Draw an arc above line LM.

5. Use a straight edge to make a line from the intersection of the two arcs above line LM to Q intersecting through L along the way. </span>
