Answer:
a₁ = 1
r = 3
Step-by-step explanation:
Since it’s a geometric series then
a₁ = 1 ( because 1 is the first term of the series)
3/1 = 9/3 = 27/9 = 81/27 = 3 then r=3.

Answer:
93,900
Step-by-step explanation:
Answer:
76.53 cm
Step-by-step explanation:
From the question, the triangle formed has 2 sides and an included angle ;
Angle, θ = C = 45°
We use cosine rule :
Taking the side to find as c
a = 100 ; b = 100
From cosine rule :
c = sqrt(a² + b² - 2abCosC)
c = sqrt(100² + 100² - 2(100*100)Cos45
c = sqrt(10000 + 10000 - 20000 * 0.7071067)
c = sqrt(20000 - 14142.135)
c = sqrt(5857.865)
c = 76.536690
c = 76.53 cm
Answer:
Step-by-step explanation:
(a). B, C and D are the distinct points that are collinear.
(b). FC and BD are the distinct lines that intersect each other at a point C.
(c). E, F, C and A are the points that are coplanar (on the same plane).
(d). Another name for plane X is plane AEF. (Since a plane is defined by the three distinct points on the same plane.
