The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.
y =3x10^8/x
What are the wavelengths for X-rays with frequency 3 x 10^18?

1. 1x10^-10m
2. 3x10^-10m
3. 3x10^26m
4. 9x10^26m

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x

If 25% of y is 30, what is 60% of y?
