The formula for the light bend would be n1*sin i= n2 * sin r
If you use "sin (90-x)= cos x" principle, you can change the sin in the equation into
n1*sin i= n2 * sin r
n1 * cos a= n2 * cos b
n2/n1= cos a/ cos b
Assuming the n constant is the ratio of the glass compared to water then the answer would be: cos a/ cos b
k= 4/9 or 0.444 in decimal form.
hope this helps!
If each notepad costs $.65, it would cost $2.60 to buy four, so she does not have enough
That would be B) 25% off. Hope this helps!
