We know that
The variable x must be either degree zero or degree 1 and the variable y must be 1st degree in order to be a linear function.
case A) x=5
the variable x is first degree but variable y is zero degree---> is not a linear function
case B) y=2x
the variable x is first degree and variable y is first degree----------> is a linear function
case C) y=2x²
the variable x is second degree and variable y is first degree----------> is not a linear function
case D) y=x³
the variable x is third degree and variable y is first degree----------> is not a linear function
the answer is
the option B) y=2x is a linear function
Answer:
Înălțimea bazinului este de 20 m
Step-by-step explanation:
Raza de bază a bazinului cilindric = lățimea peretelui dreptunghiular = 15 m
Suprafața peretelui dreptunghiular = lungime × lățime = 300 m²
300 m² = lungime × 15 m
lungime = 300 m² / 15m
lungime = 20 m
Lungimea peretelui dreptunghiular = înălțimea bazinului cilindric = 20 m
Prin urmare, înălțimea bazinului = 20 m.
Look at the trigonometry table for special angles.
From here, substitute the values in:

Simplify:

Rationalize:

And this is your answer.
Take all the non-zero digits and separate them from the zeros.
Then with zeros, how many are there?
Then multiply non-zero digits and zeros in powers.
3.482 * 10^6
A rational number for that question could be 5
