State if the polygons are similar

Mashutka [201]

Polygons are similar? Well there is no picture provided, so I have no idea what you're talking about. But I think you might be asking if in general all polygons are similar, and if that's the case, they are not. Similar means they are similar in at least one aspect, and all polygons are different from each other, only adding one line for each bigger polygon. So I don't know if this helped you, but I tried anyways.

Find an equation of the circle that has center (- 6, 5) and passes through (- 1, 1) .

dangina [55]

Answer:

$(x+6)^2+(y-5)^2=41$

Step-by-step explanation:

The equation of a circle follows the general equation $(x - h)^2 + (y - k)^2 = r^2$

Since the center of the circle is (-6, 5), we progress to the formula equation $(x + 6)^2 + (y- 5)^2 = r^2$

Since this is a circle, the distance between (-6, 5) and (-1, 1) is the radius of the circle.

$r = \sqrt{(-6 + 1)^2 + (5 - 1)^2} = \sqrt{5^2+4^2}=\sqrt{41}\\\\r^2 = 41$

So we can obtain the equation $(x+6)^2+(y-5)^2=41$

QUESTION 9 1 POINT Find the equation of a line that contains the points (-2,-5) and (3, -1). Write the equation in slope-interce

svet-max [94.6K]

Answer:

If only slope:

$y = \frac{4}{5}x + b$

If slope and y-intercept:

$y = \frac{4}{5}x - 6.6\\or\\y = \frac{4}{5}x - 3.4$

*both are correct answers see steps below*

Step-by-step explanation:

The equation to find the slope is $\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ .

The equation for slope-intercept form is $y = mx + b$ .

First, find the slope between two points.

$\frac{-1 - (-5)}{3 - (-2)} = \frac{4}{5}$

Keep the difference as a fraction if it can't be divided.

Next, plug in the slope value into the equation.

$y = \frac{4}{5}x + b$

If you also need to find what b is, pick a point; (-2, -5) OR (3, -1). Then fill in the equation with it's x and y values. (I'll do both points to show two different results).

Point (-2, -5):

$(-5) = \frac{4}{5}(-2) + b$
