Slope 2; passes through (-5,1)
the answer is
y-1=2(x+5)
10+6x=4x-4
6x-4x=-4-10
2x=-14
x-7
10=6(-7)=-32
4(-7)-4=-32
=-32
We have been given that the inverse variation shows the relationship between wavelength in meters, x, and frequency, y. We are asked to find the wavelength for radio waves with frequency .
To find the required wavelength, we substitute in our given equation and solve for x as:
We can see that both numerator and denominator has 3, so we can cancel it out.
Using quotient rule of exponents , we will get:
Therefore, the wavelength for radio waves would be meters and option B is the correct choice.
the height of cylinder B is 4 inches
