Step-by-step explanation:
So as the usual we can see that
Ab=9 and cd=9
And we can get bc by
ration reading 1
So AB:BC=1:3
SO we said that AB is 9 so we have to multiply The ratio by 9:9 we can see that the ratio will be AB:CD=9:27 the main thing here is we have got the BC which Is 27
So AD means the sum of all Points
AB+BC+CD=AD
9+27+9=AD
AD=45
Thanks in Advance

Answer:
(a) 34.
(b) Yes.
Step-by-step explanation:
The first term is 3(1)^2 + 1 = 4 ( where k = 1).
The sum of 2 terms = 3(2)^2 + 2 = 14.
The sum of 3 terms = 3(3)^2 + 3 = 30.
The sum of 4 terms = 3(4)^2 + 4 = 52.
So the first 4 terms are 4, 10, 16 and 22 . - increasing by 6.
The common difference is 6 so it is an arithmetic sequence.
The 6th term = a1 + d(n - 1)
= 4 + 6(6-1)
= 34.
Answer:
let,
x=ky
y=39 when x=7 so,
7=39k
or, k=7/39
now, when x=22
22=7y/39
or, y=39×22/7
or, y=858/7
or, y=122.57 (rounded to the nearest hundredth)
