Answer:
w = 9 ft
l = 13 ft
Step-by-step explanation:
2w + 2(w+4) = 44
simplify:
4w + 8 = 44
4w = 36
w = 9 ft
l = 13 ft
Let 
be the amount of the 30% alloy and 
the amount of the 60% alloy the metalworker will use. However much is used, the final alloy will have a mass of
kilograms. For each kg of the 30% alloy used, 0.3 kg is copper; similary, each kg of the 60% alloy contributes 0.6 kg, so that
Now,
Answer:
(-10, 2)
Step-by-step explanation:
Compare:
g(x) = (x+10)^2+2
f(x) = (x - h)^2 + k
Matching these up, term by term, we see that h = -10 and k = 2. (h, k) represents the vertex of the parabola f(x) = (x - h)^2 + k.
We conclude that the vertex of this parabola is (-10, 2).
