Find the distance between the points (-21, 17) and (33, 17)
Norma-Jean [14]
Plug it into the distance formula.

d= (sqrt) (x2-x1)^2 +(y2-y1)^2

d= (sqrt) (17-17)^2 + (33-(-21)^2
d=(sqrt) (0)^2 + (33 +21)^2
d= (sqrt) (54)^2
d= (sqrt) 2916
d=54

The distance is 54 units. 

I hope this helps!

The circle below has a radius of 3 units . Find the area of the circle. Use 3.14 for π.
const2013 [10]

Answer:

28.26 units

Step-by-step explanation:

We know the radius of the circle is 3 units, so we'll end up plugging that into the formula.

A = π(3^2) or A = π * 3 * 3

When you substitute pi for 3.14, you'll end up getting 28.26 units.

Hope this helped! :)

Answer:

Step-by-step explanation:

abs ( -2(5-(-1)) / 3 )

= abs ( -2(5+1) / 3 )

= abs ( -2(6) /3)

= abs (-12 /3)

= 4

(3(-1) -- 1) /2

= (-3 -1) /2

= -4 / 2

= -2

since 4 is greater than  - 2 this is inequality is true
