Answer:

Step-by-step explanation:
Quadratic function-
It is a function that can be represented by an equation of the form
, where
In a quadratic function, the greatest power of the variable is 2.
As in the first option the highest power is 3, so it is not a quadratic function.
Even though the power of x is 2 in the third option, but as it is in the denominator, so the overall power of x becomes -2. Hence it is not a quadratic function.
As the coefficient of
is 0 in case of fourth option, so it is not a quadratic function.
Equation in option 2 satisfies all the conditions of quadratic function, hence it is the quadratic function.
Answer: 1100 grams
Step-by-step explanation:
5kg=5000g
5000g-600g=4400g
4400g/4=1100g
You would need to isolate the "X" variable because it is common in all 3 equations.
Step-by-step explanation:
In triangle
x²=5²+12²
x²=25+144
x²=169
x= root of 169
x=13
