Answer: top left
Reason: all plots have twenty dots. Count from either side. If the tenth and eleventh are both on six than that plot is correct. Top left is the only one like that. (the median of 20 being between 10 and 11)

Find the distance between P1(1, -91°) and P2(3, 335°) on the polar plane.

Dmitrij [34]

Answer:

2.749

Step-by-step explanation:

Use the polar distance formula:

$\sqrt{r_{1}^{2}+{r_{2}^{2}-2 r_{1} r_{2}cos(theta_{1} -theta_{2})$

$\sqrt{10^{2}+{3^{2}-2(1) (3)cos(225-(-91))$

The vertices of a triangle are p(3,7) Q(7,-6) R(-8,7). Name the vertices of the image reflected across the x axis

pantera1 [17]

Answer:

Step-by-step explanation:

<u>Reflection across the x-axis</u>

Given a point P(x,y), its reflection across the x-axis will map to point P'(x,-y), i.e., the y-coordinate gets inverted.

We are given the vertices of a triangle P(3,7) Q(7,-6) R(-8,7). The vertices of the image reflected across the x-axis are:

P'(3,-7) Q'(7,6) R'(-8,-7).

The new triangle has vertices P'Q'R'.
