Answer:
...ksj
Step-by-step explanation:
Sn=sum of the n terms of the geometric sequence.
a= the first term
r=the common ratio
n=numbers of terms.
Sn=a[(1-r^n)/(1-r)]
In this case:
a=-3
r=a₂/a₁=15/-3=-5
n=9
S₉=-3[(1-(-5)⁹) / (1-(-5))=
S₉=-3(1+1953125)/6)=
S₉=-3(1953126/6)=
S₉=-3(325521)
S₉=-976563

The cuboid on the left has a volume of
.. (11 yd)*(5 yd)*(2 yd) = 110 yd^3
The cuboid at upper left has a volume of
.. (10 yd)*(4 yd)*(2 yd) = 80 yd^3
The total volume is (110 +80) yd^3 = 190 yd^3.
Answer:
C
Step-by-step explanation:
Answer:
Commutative
Step-by-step explanation:
Multiplication Property is if AxB=BxA.
Identity would be like 1x7=7
Commutative would be your problem. 5x3=3x5
Zero would be like 0x7=0
Associative would be like (3x5)x2=3x(5x2)
Distributive would be like 7x3=(5x3)+(2x3)
