Step-by-step explanation:
Parts of the question are missing.
y = a(x-h)² + k is a vertical parabola.
If a is positive, the parabola opens upwards.
If a is negative, the parabola opens downwards.
The vertex is at (h, k)
90 + 50 = 140
140 - 7 = 133
130 - 140
Simplify -45/6 to -15/2, and your answer as a decimal will be -7.5.
Answer:
A = 3(½(1 + 4)) = 7.5 units²
Step-by-step explanation:
area of a trapezoid is the average of the bases times the height.
h = -1 - (-4) = 3
base1 TR = 0 - (-1) = 1
base2 PA = 2 - (-2)) = 4
