C is the correct answer $136.00 is the cost
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
Answer:
Step-by-step explanation:
a. use what's given in the question to write an equation
36x + 12y + 24e (using e as the variable for erasers)
b. 12 is the greatest common factor between the coefficients/ constant so factor it out
12 (3x + y + 2e)
12 kits
c. use the factored expression to see how many of each item
3x - 3 pencils
y - 1 crayon
2e - 2 erasers

Step-by-step explanation:
We have,
To find, the product of the rational expressions = ?
∴
= 
= 
= 
= 
Thus, the product of the rational expressions .
Answer:
