Answer:
Domain → (-∞, 1) ∪ (1, 2]
Explanation:
Given functions are,
f(x) = 
g(x) = (x - 1)
Since, h(x) = 
Therefore, h(x) = 
This function is defined for,
(2 - x) ≥ 0 [Since, square root of negative numbers is not defined]
⇒ x ≤ 2
And (x - 1) ≠ 0 [Since, fraction is not defined for denominator = 0]
x ≠ 1
Therefore, domain of the function 'h' will be,
(-∞, 1) ∪ (1, 2]
Answer:
between 62 and 98.
Explanation:
This question can be solved faily easy:
We denote "B" as the value average of the four test values for B score (between 80 - 89) and "X" as the score on the 4th test so to find the range of values that Alice needs to score in the 4th test we only have to replace in the next formula:
We reformulate the equation in function of B
We have the next range of values for "B" (80, 81, 82, 83, 84, 85, 86, 87, 88, 89), we replace those values in the formula and operate to get the range of values we need to score in the 4th test.
As we can see for Alice to get a B for the semester she needs to score on the 4th test a score between 62 and 98 points.
Answer:
Both epinephrine and norepinephrine are released by the adrenal medulla and they circulate a neurotransmitters and hormones throughout the nervous system and circulatory system. Kara's adrenal medulla is releasing ephinephrine and norepinephrine to prepare her for fight or flight.
Explanation:
Epinephrine and norepinephrine are neurotransmitters and they belong to a class of compounds called catecholamines. While chemically both these neurotransmitters are very similar, they have different functions. Norepinephrine has an effect only on alpha receptors in your arteries, while epinephrine works of both alpha and beta receptors. Beta receptors are in the heart, lungs, and the arteries of the muscles in our skeletal system as well. Both compounds also serve as hormones in the body and having either an overabundance or a deficiency of these compounds can affect your health. Epinephrine can increase your heart rate and smooth out or relax the muscles of your breathing passages so you breathe better when experiencing a fight or flight response. Norepinephrine can constrict your blood vessels and increase blood pressure getting your body ready for action. It is also used to treat very low blood pressure.
The four main elements of the human body are oxygen, hydrogen, carbon, and nitrogen.
