Answer:
<em>Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection. Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.</em>
Step-by-step explanation:
Product: when you have the same base, the bases stay the same and you add the exponents together
Quotient: <span>When dividing terms that also contain coefficients, divide the coefficients and then divide variable </span>powers with the same base<span> by subtracting the </span><span>exponents (exponents from the denominator from numerator)</span>
3 because it square roots 3 to 3
Answer:
42 un^2
Step-by-step explanation:
You can split the hexagon into 2 triangles and a rectangle. For this, I will use the triangle that goes from (-5, 2) to (2, 2) to (-1, 4), the triangle that goes from (-5, -2) to (2, -2) to (-2, -4), and the rectangle that goes from (-5, 2) to (-5, -2) to (2, -2) to (2, 2). The top triangle is 7 units by 2 units, so using triangle formula, you get 7*2/2 = 7. The rectangle is 4 by 7, so you get 4*7=28, and the bottom triangle is 7 units by 2 units (identical to top triangle) so you get 7. 28+7+7=42 units^2
