Answer:
3rd graph.
Step-by-step explanation:
Roots of the equation are where the graph crosses the x axis. So the bottom left (3rd) graph is correct.

Formula:
V = 1/3 * b^2 * h
Plug in what we know:
V = 1/3 * 7^2 * 16
Simplify the exponent:
V = 1/3 * 49 * 16
Multiply all 3 numbers together:
V = 261.3cm^3
The answer is 17/k because there is no exact way to divide so 17/k is the quotient. :)
Answer:
a*(1 -0.5)*(1 +0.5) = 0.75a . . . . the original number "a" is larger
(a/(0.75a) -1) * 100% = 33 1/3% . . . . the original number is larger by 33 1/3% of the revised number
