Answer:
A.quadratic
Step-by-step explanation:
3x+x^2+4
Put in order from largest to smallest power of x
x^2 +3x+4
The highest power is 2
A.quadratic highest power 2
B. quartic highest power 4
C. linear highest power 1
D. cubic highest power 3
Answer:
see below for a graph
Step-by-step explanation:
Completing the square for x and y terms can help you put this in the standard form.
(x^2 +10x) +(y^2 +6y) = -18
(x^2 +10x +25) +(y^2 +6x +9) = -18 +25 +9 . . . . add square of half linear coefficient
(x +5)^2 +(y +3)^2 = 16 . . . . . . . circle centered at (-5, -3) with radius 4
To determine the number of subjects that are needed for the experiments, we multiply the number of independent variables with the number of scores. For example, there are n independent variables then, there are approximately,
number of subjects = 20 x n = 20n
1. mucus - a slimy substance produced in the nose and throat to moisten and protect them
2. sterile - free from germs
3. enables - gives ability, power, or means to; makes able
4. specialize - to develop in a special way
5. critical - being important to the outcome of a situation
For #6-10, the word in italics is the one most similar to the first word.
6. scarce | plenty | many | <em>rare</em>
7. critical | <em>important</em> | useful | relaxed
8. sterile | dirty <em>| germ-free</em> | bacteria
9. enables | teaches | makes empty | <em>allows</em>
10. specialize | stretch | <em>adapt</em> | organize
I can't help you with the last one, because that's specific to you. If you have questions on how to work on that one specifically, though, feel free to message me or post a question about it. :)
