Answer:
8cm
Step-by-step explanation:
circumference formula
50 = 2(3.14)(r)
50 = 6.28r
7.9 = r
8 = r
The equation of a line that passes through (x1,y1) and has a slope of m is
y-y1=m(x-x1)
find slope
slope between (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(-3,2) and (2,1)
slope=(1-2)/(2-(-3))=(-1)/(2+5)=-1/5
pikc a point
if we pick (-3,2)
(x1,y1)
x1=-3
y1=2
y-2=-1/5(x-(-3))
y-2=-1/5(x+3)
that is D
Answer:
bbbbbbb
Step-by-step explanation:
<span>x in (-oo:+oo)</span><span>
(1/3)*((6/5)*x-3) = 0</span><span>
1/3*(6/5*x-3) = 0</span><span>
( 1/3 )</span><span>
1/3 = 0</span><span>
x belongs to the empty set</span><span>
( 6/5*x-3 )</span><span>
6/5*x-3 = 0 // + 3</span><span>
6/5*x = 3 // : 6/5</span><span>
x = 3/6/5</span><span>
x = 5/2</span><span>
x = 5/2</span>
Answer:
A)60°
Step-by-step explanation:
a straight line is 180° then
if a line bisect it in to a half it become 90°
then
the exterior angle of a triangle is equal to the sum of two interior angles
this means 150°-90°=60°
