<span>Nonlinear negative association

The graph is by no means linear. You can see that it has a bit of curve near the beginning.

Also, if you were to find the slope of the mainly linear line, you would find that it has a negative slope. You can also tell that it is negative because the y-values are decreasing as x values are increasing. And the slope is found by change in y over change in x. Therefore, the slope would be negative.

How to state gradient and y-intercept

n200080 [17]

In summary. The graph of each equation is a straight line, m is the gradient of the line and c is the y-intercept. Conversely, if a straight line has gradient m and y-intercept c it has equation y = mx + c.

The base of a solid right pyramid is a regular hexagon with a radius of 2x units and an apothem of units. A solid right pyramid

Xelga [282]

Answer:

$6 x^2*\sqrt{3}$

Step-by-step explanation:

The base of the pyramid we need to study is a hexagon.

Let's look at the attached image of an hexagon to understand how we are going to find the area of this figure.

Notice that an hexagon is the combination of 6 exactly equal equilateral triangles in our case of size "2x" (notice that the "radius" of the hexagon is given as "2x")

Therefore the area of the hexagon is going to be 6 times the area of one of those equilateral triangles.

We know the area of a triangle is the product of its base times its height, divided by 2: $\frac{base*height}{2} = \frac{2x*height}{2}$

We notice that the triangle's height is exactly what is called the "apothem" of the hexagon (depicted in green in our figure) which measures $x\sqrt{3}$ , so replacing this value in the formula above for the area of one of the triangles:

$\frac{2x*height}{2}= \frac{2x*x\sqrt{3} }{2}=x^2\sqrt{3}$

Then we multiply this area times 6 to get the total area of the hexagon (6 of these triangles):

Area of hexagon = $6x^2\sqrt{3}$

which is the last option given in the list.

Simplify by combining like terms:<br><br> -5x-13+7y+26x

sveticcg [70]

Answer:

26x and -5x are like terms, so what you would do with these is 26x subtract -5x, which is 21x.

The final expression is:

-13 + 7y + 21x

The only pair of like terms in this expression is 26x and -5x.

Find the area of the shaded region in the figure below

kicyunya [14]

Answer:

Area of 9 cm circle = PI*radius^2 = 254.47

Area of 9 cm sircle = PI*4*4 = 50.27

Are of shaded region = 254.47 -50.27 = 204 sq cm
