Answer:
-679
Step-by-step explanation:
14, 5, -4, ...
a = 14
d = 5 - 14 = -9
nth term = a + (n - 1) d
n(78) = 14 + (78 - 1) * -9
= 14 + 77(-9)
= 14 -693
= -679
4.the dot would be on 1 1/2 and the x would be pointing toward the negative numbers
Summarizing the question,
Principle(P)=$100
Rate (r)=12%=0.12
Amount (A)=3×P=$300
Time=t=?
n=no of times the interest is compouned per year=4
Then,
A=P{(1+r/n)}^(n×t)
or,300=100×{1+0.12/4}^(4×t)
or,300/100=(1+0.03)^(4×t)
or,3=1.03^(4×t)
Taking log on both sides,
log3=log[(1.03)^(4×t)]
or,log3= (4×t)×log(1.03)
or,4t=log3/log(1.03)
or,t=log3/[4×log(1.03)]
or, t=9.29175...
t=9.3 years ANS!!!
Plan B becuase if you multiply 2 by 8 visits you get 16, and then add 15 down for that and you get 31. So 31 is less than 35 and that will be the better deal.
To find the area of the rectangular prism, use the formula:
A = width x height x length
A = 2 x 2 x 3
A = 12
Now multiply A with 0.75
12 x 0.75 = 9
x = 9 in³
hope this helps
