What is the question?
Step-by-step explanation:
Here is your ANSWER
A≈1520.53cm²
Answer:
D) all real numbers
Step-by-step explanation:
The domain is all real numbers because the graph continues to the left and right infinitely.
The discriminante :
b^2-4ac
1^2 - 4 * -2 * -28 = 1 - 224 = -223
When the discriminant (b^2-4ac) is less than 0, the equation had no real solutions.
-223<0, so, 2x^2+x-28 = 0 has no real solutions.
Hope that helps :)
The mean is 9.6
3+8+10+12+15= 48/5= 9.6
