Answer:
The correct answer is a.
Step-by-step explanation:
The domain is the plotted points on the x-axis.
The range is the plotted points on the y-axis.
(-3, 3), (0, 0), (2, -2)
Domain {-3, 0, 2}; Range: {3, 0, -2}
Answer:
10 7
20 14
30 21
Step-by-step explanation:
The gemstone has 22 edges.
We use Euler's formula on this:
F + V - E = 2
Substituting our information, we have:
14 + 10 - E = 2
Combining like terms,
24 - E = 2
Subtract 24 from both sides:
24 - E - 24 = 2 - 24
-E = -22
Divide both sides by -1:
-E/-1 = -22/-1
E = 22
R(t) = 4t
A(r) = π(r^2)
a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)
b) t = 4,
A(4) = 16*3.14*(16)^2 = 12,861.44
