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:
Dasha has 52 roses
Step-by-step explanation:
Rewrite the first sentence in an equation: (D= Dasha) (A= Anna)
D=4A
Rewrite the second sentence in an equation:
A+39=D
1) Substitute A+39 as D in the first equation:
A+39=4A
2) Subtract A from both sides:
3A=39
3) Divide both sides by 3:
A=13
4) Now substitute 13 as A in the second equation:
13+39=D
5) Solve:
D=52
Answer:
it's the first choice: 2x^3 + 5x^2 - x - 6.
Step-by-step explanation:
(f•g)(x)
= f(x) * g(x)
= (x + 2)(2x^2 + x - 3)
= 2x^3 + x^2 - 3x + 4x^2 + 2x - 6
= 2x^3 + 5x^2 - x - 6.
