Answer:
42.78 inches
Step-by-step explanation:
The anount of rainfall for the past three months are
15.82 inches
17.4 inches
9.56 inches
Therefore the total amount of rainfall for the three months can be calculated as follows
= 15.82+17.4+9.56
= 42.78
Hence the total rainfall for three months 42.78 inches
Answer:
y = x² + 18x + 94
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 9, 13) and letting a = 1, then
y = (x + 9)² + 13 ← expand (x + 9)² using FOIL
= x² + 18x + 81 + 13
= x² + 18x + 94
