Answer:
The answer to your question is AB = 6.9
Step-by-step explanation:
Data
∠A = 70°
∠C = 62°
BC = 7.3
AB = x
Process
1.- To solve this problem use the law of sines
AB / sin C = BC / sin A
Substitution
AB / sin 62 = 7.3 / sin 70
Solve for AB
AB = 7.3(sin 62) / sin 70
AB = 7.3(0.883) / 0.940
AB = 7.3 (0.939)
Result
AB = 6.8

Step-by-step explanation:
Standard form of a quadratic is f(x) = ax² + bx + c.
To convert to vertex form, the simplest method is to find the x-coordinate of the vertex using h = -b/(2a).
Then, plug back into the equation to find the y-coordinate of the vertex. k = f(h).
Finally, the leading coefficient is the same as the standard form, a.
f(x) = a(x − h)² + k
Another method is to complete the square.
X 0 y was 30
at x 12 y is about 55
12-0 = 12
55-30 = 25
25/12 = 2.08 inches per year average
so answer should be D
