F(x)=25-x^2
g(x)=x+5

f/g(x)=(25-x^2)/(x+5)

f(x) is in binomial form so 25-x^2 can also be written as (5-x)(5+x)

so

f/g(x)=(5-x)(5+x)/(x+5)
f/g(x)=5-x

Graph the set of points. which model is most appropriate for the set (-6 4) (-4 0) (-3 -2) (-1 -7)

Free_Kalibri [48]

Answer:

The linear regression model is $y=-2.19x-8.92$ .

Step-by-step explanation:

The given data points are (-6 4) (-4 0) (-3 -2) (-1 -7). Plot these points on a coordinate plane.

From the graph it is clear that the point are in the form of a straight line, so we need to use the linear regression model.

The general linear regression model is

$y=ax+b$

Using technology we get

$a=-2.1923076923\approx -2.19$

$b=-8.9230769231\approx -8.92$

Put a=-2.19 and b=-8.92 in the above equation.

$y=-2.19x-8.92$

Therefore the linear regression model is $y=-2.19x-8.92$ .

Simplify. Assume that no denominator is equal to zero. <br><br> 4^12/4^5

Georgia [21]

Answer:

16,384 or 2^14

Step-by-step explanation:

4^12= 4*4*4*4*4*4*4*4*4*4*4*4=16,777,216

4^5= 4*4*4*4*4=1024

16,777,216/1024=16,384

16,384=2^14
