Answer:
Adam's car will be 8,406£ in 22 years.
Step-by-step explanation:
I. Find the lose value of 2.5% car by
2.5/100 = x/18,680
46,700/100 = x
x = 467 or the lose value in 1st year.
II. Find the true value of Adam's car by
n year = 18,680 - 467(n)
1st = 18,680 - 467(1)
= 18,213 means if he sell his car now, he'll get 18,213£
22th = 18,680 - 467(22)
= 18,680 - 10,274
= 8,406£
That makes 8,406£ is the right answer.
Hope that help :)
Answer:
Terms are 2 , 3 , 7 , 31
Step-by-step explanation:
1) given a1 = 2
an+2 = 2(an) -1
put n = 1
a1 + 2 = 2a1 -1
put value of a1 in above
you'll get a3 = 2² -1
a3 = 4-1
a3 = 3
put n = 3
a3 + 2 = 2a3 -1
a5 = 2³-1
a5 = 8-1
a5 = 7
put n = 5
a5 + 2 = 2a5 -1
a7 = 2⁵ -1
a7 = 32 -1
a7 = 31
Hope you got it.
Similarly you can find 2nd one's term t23
tn = 5*n -4
here n = 23
t23 = 5 * 23 - 4
t23 = 115 -4
t23 = 111
Hope this helps you.
Answer:
you would go by pemdas so it would be (63x-7x)24-1/7
hope it helps :)
I think it's d 67 or c 55 because it's the nearest number
