A function is described as a quadratic function if the highest power of the variables of the function is 2.
For
The highest power of x is 1, hence, the function is not a quadratic function.
For
The highest power of a is 2, hence, the function is a quadratic function.
For
The highest power of y is 1, hence, the function is not a quadratic function.
For
The highest power of b is 2, hence, the function is a quadratic function.
Therefore, the quadratic functions are (4a + 2)(2a - 1) + 1 = 0 and <span>2b(b - 7) + b = 0</span>
Answer: 56
Step-by-step explanation: 100 multiplied by 50% is 50 + 12% =56
Answer:
80%
Step-by-step explanation:
Cause four divided by five equals .8 so then multiply it by ten and u get 80%
Answer: point b
Step-by-step explanation:
eatch mark on the line is 0.1, b is right behind the 8.6 mark in the middle making it 8.65
If you're looking for the angle it is a 30, 60, 90, but if you're looking for the length of the hypotenuse it's 5
