Answer:
The sum of geometric series is 716144
Step-by-step explanation:
Given
First term=a_1= -11
Last term=a_8=859375
Common ration of geometric series=r= -5
And
Total terms in geometric sequence=n=8
We know that the formula for sum of geometric series is:
S_n= (a_1 (1-r^n))/(1-r)
= (-11(1-(-5)^8)/(1-(-5))
= (-11(1-5^8))/(1+5)
= (-11(1-390625))/6
=(-11(-390624)))/6
=4296864/6
=716144
So the sum of geometric series is: 716144 ..
just multiply 12 times 4. thats 48. so 48 divided by 4 is 12
If you mean the sum of the two square roots, it would be 11. The square root of 25 = 5 and the square root of 36 = 6.. and 5 + 6 = 11
Answer:
A 8 hours
Step-by-step explanation:
Last week she baby sat 12 hours.
This week she baby sat x hours.
Last week she baby sat 1 1/2 times as many hours as this week.
12 = 1 1/2 × this week
12 = 1 1/2 × x
1.5x = 12
x = 12/1.5
x = 8
Answer:
A 8 hours
The answer is [-3,2] but the graph isn't on there u cant see. it would be more better understanding if shown the graph to go with it.
