Remark
I take it that you mean y^2 = 36x. The first thing you should try and do is get a graph of the given equation. I've done that for you. Notice a few characteristics.
1. The graph opens left. Usually most graphs like this one open up or down.
2. The graph is open ended on the right.
3. There is only one open end.
4. The graph is continuous, but it is not a function. (that's a fact -- but not needed in this question).
When you get a graph looking like this, you have either a graph called a quadratic or a parabola. Either (but not both) could be your answer. If you have choices list them in a comment.
Answer:
No, because water temperature is confounded with brand of detergent.
Step-by-step explanation:
There is a very possible chance of allowing a third or confounding variable to have creepwd into the research. The aim was to investigate which of two detergents prevents color from fading. Hence, the test for both detergents should be carried out under the same research condition. However, with adoption of different water temperature for each of detergent A and B, there may be a relationship between fading and water temperature which is not what are trying to investigate. This difference in temperature will thus cause a spurious relationship in our research. Hence, water temperature has been confounded with detergent brand, making this experimental design a bad one.
Answer:
∅ ≈ 48.2º
Step-by-step explanation:
cos∅ = adj/hyp = 10/15 = 2/3
Therefor
∅ = arccos 2/3
use calculator
∅ = 48.189685104221402
∅ ≈ 48.2º
A) f(x) = x-2 because the points in the y axis are -2 from the origin and x goes first
Answer:
A and E
Step-by-step explanation:
substitute and odd number into every equation :)
