To find this number, let's represent the unknown amount of students with the variable x:
356 + 365 + x = 977
721 + x = 977
x = 256
There are 256 students in ninth grade.
Answer:
384
Step-by-step explanation:
For the answer to the question on w<span>hat is the equation of the quadratic graph with a focus of (5, 6) and a directrix of y = 2?
</span>the vertex = (5,4)
<span>p = 2 </span>
<span>4*2(y-4) = (x-5)^2 </span>
<span>y = (1/8)(x-5)^2 + 4
</span>
I hope my answer helped. Have a nice day!
1) The domain of the graph is the set of x-values for which the function is defined, that is - x ≥ 0 => x ≤ 0 => all real numbers less than or equal to zero.
2) The range of the grpah is the set 0 images (or y-values) feasible. As you see on the graph that is y ≤ 0 => all real numbers less than or equal to zero.
3) Conclusion: the only statement that meet those facts is the third one: the range and the domain of the graph are the same.
Answer: the third option: the range and the domain of the graph are the same.
