Answer:
1023.75
Step-by-step explanation:
The sum of a geometric sequence is
sum = a( 1 - r^n) / (1-r)
where a is the first term r is the common ratio and r^n is the nth term
We need to find the common ratio
r = 256/512 = 1/2
sum = 512 ( 1 - 1/2^12) / ( 1-1/2)
=512( 1-.000244141) / (.5)
=512(.999755859) /.5
=1023.75

Answer:
<h2>0.15 inches per month</h2>
Step-by-step explanation:
step one:
This problem is focused on the growth rate of a plant.
given data
the plants grow 5 inches in 34 months
and also that 1 month= 4 weeks
step two:
We can still say that
if 34 months see a growth of 5 inches
then 1 months will be X inches
cross multiply we have
X= 5/32 inches
step three:
converting this number to decimal we have
X= 0.15 inches per month
Therefore the growth rate would be
0.15 inches per month
Answer:
It took 5 hours
Step-by-step explanation:
Because 28 times 5 is 140 plus 25 for the call is 165.
Slope = -6
Y-intercept = (0,11)
