Answer:
(d) -- see attached
Step-by-step explanation:
A graph that shows exponential decay is one that tends toward a horizontal asymptote as x gets large.
__
A basic (parent) exponential decay curve is concave upward and tends toward zero as x gets large. The fractional change in any interval is the same as for any other interval of equal size. The curve attached decreases by a factor of 2 when x increases by 1.
I think the answer would be C. (btw, you should charge your phone/tablet, lol)
Answer:
Width = 4ft
Step-by-step explanation:
Area of the rectangular mural = Length × Breadth
7 ft tall and 11 ft wide.
(11 - 2W)(7 - 2W) = 88
77 -22W - 14W + 4W² = 88
77 -36W + 4W² = 88
4W² - 36W + 77 - 88
= 4W² - 36W - 11
W = 4ft
