A perfect number is a number where the sum of its divisors is equal to the number.
For example 6: 1 + 2 + 3 = 6
Another example is 28: 1 + 2 + 4 + 7 + 14 = 28
Here is a short list of perfect numbers: 6, 28, 496, 8128, <span>33550336, and the numbers get way bigger as we go on.</span>
Answer:
2.4x105
Step-by-step explanation:
D
Answer:
yields 2 real roots
Step-by-step explanation:
To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.
•
yields 2 real roots
•
yields 1 real root
• [tx]b^2-4ac<0[/tex] yields no real roots
Example:
where a=4, b=-7, and c=2
.
It has 2 real roots
Answer:
It is either 11/12 or 0.91666666667.....
Step-by-step explanation:
Because this can not be actually divided into a "number" like 2 or 5, we can only get a approximate. Like the top answer.
Round to the nearest ten is 0.9
Round it to nearest hundredths is 0.92
D (-4 , -1)
relflected over x-axis= (4 , 1)
180 degrees= (-4 , -1)
