Do you mean the top of the ladder and the top of the building? If so, it would be 9 feet<span />

Initially, a spinner points west. Chenille moves it clockwise 2 1/4 revolutions and then counterclockwise 3 3/4 revolutions. In

Zigmanuir [339]

Answer: East

Step-by-step explanation:

Given

A spinner initially pointing towards west is made to move $2\frac{1}{4}$ revolutions clockwise and $3\frac{3}{4}$ revolutions counterclockwise.

After one complete revolution pointer points at the same direction.

So, the net movement of the spinner is

$\Rightarrow 3\dfrac{3}{4}-2\dfrac{1}{4}\\\\\Rightarrow \dfrac{15}{4}-\dfrac{9}{4}\\\\\Rightarrow \dfrac{15-9}{4}\\\\\Rightarrow \dfrac{6}{4}\ \text{or}\ 1\dfrac{2}{4}\ \text{CCW}$

That is 1 and half-revolution counter clockwise

After 1 revolution, direction is same, but after half revolution it points towards east.

The final direction is east.

How do I rewrite a quadratic into graphing form

Juli2301 [7.4K]

Step-by-step explanation:

Standard form of a quadratic is f(x) = ax² + bx + c.

To convert to vertex form, the simplest method is to find the x-coordinate of the vertex using h = -b/(2a).

Then, plug back into the equation to find the y-coordinate of the vertex. k = f(h).

Finally, the leading coefficient is the same as the standard form, a.

f(x) = a(x − h)² + k

Another method is to complete the square.

Which of the following equations has the same solutions as the equations 3x+2y=-12

Marianna [84]

B, C, E, F

<h2>Explanation:</h2>

In this problem, we have the following equation of a line written in Standard form:

$3x+2y=-12$

So we need to choose the equations that has the same solutions as this equation. If we multiply each equation by a constant term and find the same solution as the given equation, then they will have the same solution. This is only true fro options B, C, E and F.

Option B.

$-3x-2y= 12 \\ \\ Multiply \ both \ sides \ by \ -1: \\ \\ (-1)(-3x-2y)=(-1)(12) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

Option D.

$15x+10y= -60 \\ \\ Multiply \ both \ sides \ by \ 1/5: \\ \\ (\frac{1}{5})(15x+10y)=(\frac{1}{5})(-60) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

Option E.

$6x+2y= -12 \\ \\ Multiply \ both \ sides \ by \ 1/2: \\ \\ (\frac{1}{2})(6x+2y)=(\frac{1}{2})(-24) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

Option F.

$1.5x+y= -6 \\ \\ Multiply \ both \ sides \ by \ 2: \\ \\ (2)(1.5x+y)=(2)(-6) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

For the other options, there is no any constant term that multiplies both sides of the equation and gives us the same given equation.
