Answer:
b.
Step-by-step explanation:
Quadratic equations are suppose to be written as:
so the new quadratic equation for this problem will be:
Now rearrange the terms:
Then use the Quadratic Formula to Solve for the Quadratic Equation
Quadratic Formula =
Note: Ignore the A in the quadratic formula
Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.
a = 3
b = -7
c = -1

Three times the product of four and twelve.
Answer:
P(she selects the route of four specific capitals) = 1 in 2,686,320 or 3.72 x 10⁻⁷
Step-by-step explanation:
Assuming that the order at which she visits each of the four cities matters, the number of possible routes is the permutation of choosing 4 out of 42 capitals:
Therefore, the probability that she selects the route of four specific capitals is 1 in 2,686,320 or 3.72 x 10⁻⁷

Answer:
B. 5626.9
Step-by-step explanation:
• volume of cylinder= pi(r)2h
• plug in the values into the equation
• pi(8)2(28)
pi=3.14 so 3.14(8)2(28)
• multiply all the values
• you get 5629. 73
• b is the closest the that answer since it says approximate
