Answer:

The exponential model

Step-by-step explanation:

A coefficient of determination is a measure of how well the graph of a regression fits the data set. The closer this coefficient is to 1, the better the fit.

The closest coefficient we have to 1 is 0.91, which is that of the exponential model. This means the exponential model is the best fit.

What is the value of x in the equation shown? 2(X + 8) - 4x = 10x + 4

Anna007 [38]

Answer:

Option C: X=1

Step-by-step explanation:

2(X + 8) - 4x = 10x + 4

2X + 16- 4X= 10X + 4

-2X +16 =10X + 4

16 - 4 = 10X+2X

12 =12X

X=1

using the formula: 8 * 10 = 80 mm²

$3\frac{1}{2} -\frac{2}{3}$

$\frac{7}{2} -\frac{2}{3}$

$\frac{21}{6} -\frac{4}{6}$

$\frac{21-4}{6}$

$\frac{17}{6}$

$2\frac{5}{6}$

Please someone help with this

Sholpan [36]

A=16 and b=63

So we have to use the Pythagoras theorem for this and that is:
a^2+ b^2 = c^2

And we want to find c , which is the long side of the triangle so..

16^2+ 63^2= 4225
So c^2 =4225

c= square root of 4225
C= 65

Substract the following :(4x^3+6x+9)-(-15x^2+7x-2)

STatiana [176]

To solve this, we need to rearrange to get like terms by each other. Remember to distribute the negative.

$4x^3+6x+9+15x^2-7x+2

4x^3+15x^2+6x-7x+9+2

4x^3+15x^2-x+11$
