Answer:
12.124-3
Step-by-step explanation:




There are 100 pennies in a dollar. We can divide 12000 pennies by 100 to find out how much they are worth in dollars.
12000/100 = $120
Equation B is written in vertex form, which means you can read the vertex (extreme value) from the numbers in the equation.
Vertex form is
y = a(x -h)² + k
where the vertex (extreme point) is (h, k). Whether that is a maximum or a minimum depends on the sign of "a". When "a" is negative, the graph is a parabola that opens downward, so the vertex is a maximum.
Equation
B reveals its extreme value without needing to be altered.
The extreme value of this equation is a
maximum at the point
(2, 5).
Step-by-step explanation:
it's 6
as,
-12 × 6 = -72
