The angle of rotation is the minimum angle in which you rotate a regular polygon such that the figure appears unchanged. The formula for that is dividing one angle of revolution by its number of sides.

Angle of Rotation = 360°/n
Angle of Rotation = 360°/72 = 5°

Select the correct answer. A sound wave enters a new medium where sound travels faster. How does this affect the frequency and w
Ulleksa [173]

Answer:

The correct answer is E. Neither the frequency nor the wavelength is affected. Explanation: The wave frequency does not affect the speed of that wave. An increase in frequency of a wave causes a decrease in wavelength while the wave speed remains the constant. The speed of the waves is significantly higher at higher tensions.

I NEED HELP WITH NUMBER 2
sashaice [31]

5y+2x = -7~~~~~......(i)\\\\y = -2x +5 ~~~~~~.....(ii)\\\\(i) -(ii):\\\\5y+2x -y = -7-(-2x+5)\\\\\implies 4y +2x = -7 +2x -5\\\\\implies 4y +2x -2x = -12\\\\\implies 4y = -12\\\\\implies y = - \dfrac{12}4 = -3\\\\\\\text{Substitute}~ y=-3~ \text{in equation (ii):}\\\\\\-3 = -2x +5\\\\\implies 2x = 5 +3 \\\\\implies 2x = 8\\\\\implies x = \dfrac 82 =4\\\\\text{Hence,}~ x = 4

The length of a rectangle is 3 in more than twice it’s width, and it’s area is 65 sq in. What is it’s width?
likoan [24]

Answer: 5 inches.

Step-by-step explanation:

The  formula for calculate the area of a rectangle is:

A=w*l

Where l is the length and w is the width.

If  the length of a rectangle is 3 inches more than twice it’s width, then:

l=2w+3

Substitute l=2w+3 and the area into the formula and solve for the width:

65=(2w+3)w\\65=2w^2+3w\\0=2w^2+3w-65

Use the quadratic formula:

w=\frac{-b\±\sqrt{b^2-4ac}}{2a}\\\\w=\frac{-3\±\sqrt{3^2-4(2)(-65)}}{2(2)}\\\\w=5\\w=-6.5

Choose the positive value.

Therefore, the width is: 5 inches.
