Answer:
<h2><u><em>
46 cm²</em></u></h2>
Step-by-step explanation
the figure is composed of a square with an isosceles right triangle inside, we find the area of the square and we take away the area of the triangle.
Triangle area = lxl, right-angled triangle area side by side divided by two.
8 * 8 = 64cm²
6 * 6 : 2 = 18 cm²
Area of the shaded region
64 - 18 = 46 cm²
Answer:7
Step-by-step explanation:
just because
Answer: 
Step-by-step explanation:
Let the given parabolic mirror opens upwards and vertex=(0,0)
Focus point of the parabolic mirror is located 2 inches from the vertex of the mirror. ∴ p=2
Since, the parabola opens upward, then the equation of the parabola is of the form 
Substitute the value of p=2 in this, we get the equation of the parabolic mirror

Hence, the equation of the parabola that models the cross section of the mirror is 
You have 40/16
simplified by 8 and you have 5:2
so the answer is d. 5:2
