Which function is a quadratic function? y – 3x2 = 3(x2 + 5) + 1 y2 – 7x = 2(x2 + 6) + 7 y – 2x2 = 6(x3 + 5) – 4 y – 5x = 4(x + 5

Anna71 [15]

Answer:

Option A.

Step-by-step explanation:

The general form of a quadratic function is

$y=ax^2+bx+c$

It means, power of y should be 1 and highest power of x should be 2.

In option A,

$y-3x^2=3(x^2+5)+1$

$y-3x^2=3x^2+15+1$

$y=3x^2+16+3x^2$

$y=6x^2+16$

It is a quadratic function.

In option B,

$y^2-7x=2(x^2+6)+7$

Here, power of y is 2. So, it is not be a quadratic function.

In option C,

$y-2x^2=6(x^3+5)$

Here, highest power of x is 3. So, it is not be a quadratic function.

In option D,

$y-5x=4(x+5)+9$

Here, highest power of x is 1. So, it is not be a quadratic function.

Therefore, the correct option is A.

Meghan also wants to walk to get some exercise, rather than going to the gym. She decides to walk along arc AB. How far will she

Karo-lina-s [1.5K]

Answer:

π*AB

Step-by-step explanation:

I m not quite sure about your question because it is lack of details.

However, as my per understanding, Meghan decides to walk along arc AB it means she walks an interval equal to the circumference of the circle AB.

So, apply the formula in caculating the circumference of the circle, we have:

π*d = π*AB

So, she walk a π*AB distance.
