Step-by-step explanation:
35 × 10^-3 × 102 × 10 ^-2
35×102 ×10^-3-2
3570× 10^-5
3.57×10^-2
Felt appears to be right triangles
A appears to be an equilateral triangle
The function in vertex form is

(refer to your other post I solved it there).
The general form of quadratic equations in vertex form is

, where (h, k) is the vertex of the parabola.
Here, a = 1, h = -6 and k = -54
Therefore, the vertex is (-6, -54) and it is a maximum because a = 1 is postive.
The m (angle sign) for 4 is 38. I hope i helped.
