Nesterboy [21]

Answer:

Step-by-step explanation:

let the horizontal distance be x

(17.8-1.5)/x = tan 38

or x = 16.3/tan38

or x = 20.863

When a trend line is drawn on a scatterplot, there are 4 points above the trend line. About how many points should be below the

scoundrel [369]

There is no exact rule for lines of best fit. However, in general, there should be roughly the same amount above as below. So, if we are following this rule, there should be about 4 below as well.

The function. In the graph is f(x) =

Tanya [424]

Answer:

$x^3-2x^2-5x+6$

Step-by-step explanation:

We have been given a graph of the function f(x).

Now we need to use that graph to find the equation of the graph and match with the correct choice from the give choices:

$x^4-2x^2+5x+6$

$x^3-2x^2-5x+6$

$x^3-2x^2+5x+6$

$-x^4-2x^2+5x+6$

We see that graph has end points in opposite direction then the degree of polynomial must be ODD.

Available degrees are 3 and 4. Degree 3 is odd so it is choice B or C.

Only $x^3-2x^2-5x+6$ satisfies the given points from graph.

Hence correct choice is $x^3-2x^2-5x+6$ .
