Answer:
The index of refraction of the second medium is higher.
Step-by-step explanation:
The answer of t he trapezoid area problem is 112.
Answer:
The correct answer is B.
Step-by-step explanation:
In order to find this, calculate out the discriminant for each of the following equations. If the discriminant is a perfect square, then it can be factored.
Discriminant = b^2 - 4ac
The only of the equations that does not yield a perfect square is B. The work for it is done below for you.
Discriminant = b^2 - 4ac
Discriminant = 7^2 - 4(2)(-5)
Discriminant = 49 + 40
Discriminant = 89
Since 89 is not a perfect square, we cannot factor this.
17x + 16x + 12x =180
45x = 180
x = 4
Largest angle = 17*4 = 68 degrees
Answer:
The correct answers are y=sec x, and y=csc x
