Answer:
Step-by-step explanation:
Consider the figure as the difference of a trapezoid and a rectangle.
<u>Area of the trapezoid:</u>
- a = 3 - (-2) = 5 units
- b = 9 - (-6) = 15 units
- h = 5 - (-5) = 10 units
- A = (a + b)h/2 = (5 + 15)(10)/2 = 100 square units
<u>Area of the rectangle:</u>
- l = 5 - (-2) = 7 units
- w = -1 - (-5) = 4 units
- A = lw = 4*7 = 28 square units
<u>Area of the figure:</u>
- 100 - 28 = 72 square units
H (x) = 5x^2+40x+64
y = (5x^2+40x+60) + 4
y = 5(x^2+8x+12) + 4
y = 5(x+2)(x+6) + 4
y-4 = 5(x+2)(x+6)
This means that the solutions, or where the parabola crosses the x-axis, are at x+2=0 and x+6=0, or x=-2, -6
So the midpoint of -2 and -6 is -4, the axis of symmetry is x=-4
Answer: I believe its D. other function
Answer:
x=0
