Answer: 0.014
Step-by-step explanation: 5 divided by 18!
Answer:
I think the answer is option A
The <em>correct answers</em> are:
C) No: we would need to know if the vertex is a minimum or a maximum; and
C)( 0.25, 5.875).
Explanation:
The domain of any quadratic function is all real numbers.
The range, however, would depend on whether the quadratic was open upward or downward. If the vertex is a maximum, then the quadratic opens down and the range is all values of y less than or equal to the y-coordinate of the vertex.
If the vertex is a minimum, then the quadratic opens up and the range is all values of y greater than or equal to the y-coordinate of the vertex.
There is no way to identify from the coordinates of the vertex whether it is a maximum or a minimum, so we cannot tell what the range is.
The graph of the quadratic function is shown in the attachment. Tracing it, the vertex is at approximately (0.25, 0.5875).
If the digits are a, b and c, the number n is 100a+10b+c
Here are the equations:
a number equals fifteen times the sum of its digits:
100a+10b+c = 15(a+b+c)
if its digits are reversed, the resulting number exceeds n by 396:
100a+10b+c+396 = 100c+10b+a
the one’s digit is one larger than the sum of the other two:
a+b+1 = c
Solving it gives you a=1, b=3, c=5, the number is 135.
