Answer:

So we have: (8x+16)-(3x^2-3x-15)

We will start operating the parenthesis, so we will have to pass the - to the members of these  (we will have to change their sign):

(8x+16)-3x^2+3x+15

We can also removee the first parenthesis, as it doesn't change the meaning if it's or if it isn't::

8x+16-3x^2+3x+15^

Now, we will group the numbers

-3x^2+8x+3x+16+15

And we can now do the operations:

-3x^2+8x+3x+16+15=-3x^2+11x+16^

Is height a function of age? Explain.
aleksandr82 [10.1K]
No. Age function has nothing to do with height. A five foot man could be ninety three, or a five year old boy could be four feet tall. Age and height have nothing to do with each other.

Serhud [2]

We have to see which model (quadratic or linear) best represents the data.

We can use software to fit this data set.

Linear model:

Quadratic model:

The quadratic model has a slightly better fit than the linear model.

But the value of R² = 0.176 shows that the fit is very weak, so we can conclude that this is not a good model for the data.

Answer:

Quadratic model, 0.176.

No, 0.176 is a very low R² value.
