Answer:
<em>32.5 m^2</em>
Step-by-step explanation:
B = 377lw
I will use L for length instead of l.
B = 12,252.5 BTU
w = 5 m
First, we find the length.
12,252.5 = 377(L)(5)
12,252.5 = 1885L
L = 6.5
The length is 6.5 m. The width is 5 m.
A = LW = (6.5 m)(5 m) = 32.5 m^2
Parent Function: f(x) = x^2
Right 2 units: f(x) = (x^2 - 2)
Down 4 units: f(x) = (x^2 - 2) - 4
Reflection over x-axis: f(x) = - (x^2 -2) + 4
Answer: f(x) = - (x^2 -2) + 4
