Answer:

(2,8) or (2,-8)

Step-by-step explanation:

The two points already given are 8 units apart, so the third point would have to be either 8 units upward or 8 units downward.  Now for an equilateral triangle, the x-coordinate has to be a number between the x-coordinates of the points already given, in this case, -2 and 6.  On a coordinate plane, the middle x-value is 2.  Therefore, the ordered pairs that make the most possible coordinates of vertex R are (2,8) or (2,-8) depending on whether you want the point of the triangle to face upward or for it to face downward.

What multiplies to be 280 and adds to be negative 36
photoshop1234 [79]
The two numbers are -18+ 2√(11) and -18 -2√(11).

-18+ 2√(11)+ [-18 -2√(11)]= -36
[-18+ 2√(11)]* [-18 -2√(11)]= 280.

Hope this helps~

A circle with area 3/2pi and central angle of 60 degrees. What is the area of the circle
Anika [276]

Answer:

28.28(simplified from 28.2743338834)

Step-by-step explanation:

area of sector= (center angle/360)*area of circle

we are already given the area of sector as 3/2pi

so

3/2pi=(60/360)*x

(x is area of circle)

3/2pi=4.71238898038

4.71238898038=1/6x

divide both sides by "1/6"

28.2743338834=x

hope this helps!
