Answer:

Step-by-step explanation:

Since G(0) = g(0) = 20, the parabolic graphs of these functions share a y-intercept: (0, 20).

Completing the square puts these equations into vertex form, which simplifies comparisons of the graphs:

G(x) = 2x^2 - 12x + 20 becomes

2(x^2 - 6x + 9 - 9) + 20, or

2(x - 3)^2 - 18 + 20, or 2(x - 3)^2 + 2. Comparing this result to

a(x - h)^2 + k, we see that the vertex is located at (3, 2).

Going through the same process for g(x) 2x^2+12x+20, we get:

g(x) = 2(x + 3)^2 + 2, whose vertex is at (-3, 2).

Next time, please include ALL info pertaining to your question, including the set of possible answer choices. Thank you.

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.

Twin 72 x 92 King 121 x 121

Linings:

If you supply the lining, please be sure it measures at least 4” larger than the length and width of the quilt top. We can also supply the lining from our own fabric at the retail cost. If the lining requires piecing, we can do this for a $10 per seam fee.

Step-by-step explanation:

Rate of change means how much does the number of snowflakes go up each time (on a different question you might find the number goes down each time)

"Initial value" means whatthe number if snowflakes at step zero. We have to work backwards to find that number. For the equation, fill in the rate in front of the x (we use m for that number) and add in the initial value (b) in the format y=mx+b . The information for the table is in the picture (the step numbers and number of snowflakes)
