<span>For the answer to this question,
Let x = depth of the gutter
then
18 - 2x = width of the gutter
Cross section area
A = depth x width
</span><span> = x(18 - 2x)
A = 18x - 2x^2
:
Axis of symmetry will give x value for max area:
x = -b/(2a)
x = -18/(2x(-2))
x = 4.5 inches is the depth for max area
</span><span>Max area: 4.5 * 9 = 40.5 sq/in
I hope my answer helped you.</span>
Y=7x-1 is that what youre looking for?
Answer:
B) y = 1/5x + 12/5
Step-by-step explanation:
2 = 1/5(-2) + b
2 = -0.4 + b
2.4 = b
2.4 = 12/5
Answer:
yepp that the answer will be correct just try ittt
A= P(1 + r/n) ^nt
21000=7000(1+0.055/2)^1t
t = 20.52 years
