Answer:
S(10)=3*(1-(5/3)^10)/(1-5/3)
Step-by-step explanation:
It is Geometric series with r:
r=5/3=(25/3)/5=5/3
a=3
Sum of G.S. in formula:
S(n)=a(1-r^n)/(1-r)
S(10)=3*(1-(5/3)^10)/(1-5/3)
=246.5725...
Answer:
y = 20
x = 120
Step-by-step explanation:
2x + 3y = 300
3x + 5y = 460
mutliply eqn 1 by 3 and 2 by 2
6x + 9y = 900
6x + 10y = 920
y = 20
x =
Answer: y= -2 (x+1)
Step-by-step explanation:
this would be the “inverse” of the original equation making them cross at exactly 1 point
Answer:
1296 in³
Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V = Ah ( A is the area of the base and h the perpendicular height (
Here A = 18 × 18 = 324 and h = 12, thus
V = × 324 × 12 = 1296 in³
