Step-by-step explanation:
If the mystery number rounds to 700, then it has 3 digits before decimal points and two digits after decimal point.
Hence, the mystery number is
The digit in the tenth place is double the digit in the tens place, so
If b = 1, then d = 2
If b = 2, then d = 4
If b = 3, then d = 6
If b = 4, then d = 8
The difference between the digit in the hundreds place and the ones place is 3, so
The first digit can be only 7, because b < 5 and the number rounds to 700. So
If a = 7, then c = 4
All possible answers:
714.2e
724.4e
734.6e
744.8e,
where e is an arbitrary digit from 0 to 9.
There are 40 possible numbers which match the situation.
Given:
The quadratic equation is
To find:
The x-coordinate and y-coordinate of the vertex.
Solution:
If a quadratic function is defined by , then the vertex is defined as:
If , then the function has a maximum at the vertex and ff , then the function has a minimum at the vertex.
We have,
Here, .
Since , therefore the function has a minimum at the vertex. So, fill min in first blank.
Now,
Putting x=3 in the given function, we get
Therefore, the vertex is at point (3,-12).
