Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large (100000000000) or small (0.00000000001) to be written in a conventional manner.
The use of this notation is based on powers of 104
Example:
Big numbers:

Small numbers:

However, in areas such as physics and chemistry, scientific notation is important to make approximations such as:
mass of a proton
mass of an electron and others.
Answer:
x=-6
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(6-2)/(-6-(-6))
m=4/(-6+6)
m=4/0
undefined
x=-6
Answer:
B
as [tex]\cos(\theta)=\srqt{1-\sin^2(\theta)}\[tex]
and since theta is in second quadrant, where cosine is negative,
so -√(1-z²)
Answer:
58.86 mg
Step-by-step explanation:
8 mg = 16 kg
1 kg = 2.2 lb
use substitution
8 mg = 16 (2.2 lb)
8 mg = 35.2 lb
8 mg / 35.2 lb = x mg / 259 lb
2072 = 35.2 x
x = 58.86 mg
Answer:
45/512
Step-by-step explanation:
5C3(0.25³)(0.75²) = 45/512
