The answer of the question is A
The correct answer would be A) Puberty.
Puberty
maturational, hormonal, & growth process occurring when reproductive organs begin to function & secondary sex characteristics develop
The Statements which are true are;
- Choice B; Subtraction and Addition are INVERSE operations.
- Choice D; Multiplication and Division are INVERSE operations.
Inverse Operations:
Operations said to be inverse if both operations are complementary.
- <em>On this note, when a number x is added to a given number y, we get a number z. Also, when we add x back to the number z; we get number y back.</em>
- <em>Similarly, when we multiply a number, x by y; we get z. When z is then divided by y; we get the number x back.</em>
Ultimately,
- Multiplication and Division are INVERSE operations.
- Addition and Multiplication are INVERSE operations.

Answer:
a) ±0.73
b) ±3%
Step-by-step explanation:
One side of the right angle triangle is 12cm
The opposite angle(x) is 30 degree
Possible error = ±1degree
a) Let the hypotenus= h
h/12 = cosecx
h = 12cosecx
Differentiate h with respect to x
dh= -12cosecxcotcdx
The possible error in the angle measurement is dx
dx= ±1degree
Convert degree to radians
dx = ±1*π/180
dx = ± π/180
Put x and dx into dh
dh = -12cosec30cot30(±π/180)
= -12(2)(√3)(±π/180)
= -24√3(±π/180)
= ±24π√3/180
= ±0.73
b) To find the percentage error, recall that
dh = 12cosecx
dh = 12cosec30
dh = 12(2)
= 24
Percentage error =
(change in value/initial value) 100
Percentage error = (dh/h)100
= (±0.73/24)100
= ±0.030*100
= ±3%
