What is the first term of the geometric sequence whose fifth term is 1/24 and tenth term is 1/768
Neporo4naja [7]
An=a1r^(n-1)

given
a5=1/24
a10=1/768

we know that
a5=1/24=a1r^(5-1) and
a10=1/768=a1r^(10-1)

so
1/24=a1r^4
1/768=a1r^9

(a1r^9)/(a1r^4)=r^5=(1/768)/(1/24)=1/32

r^5=1/32
take 5th root of both sides
r=1/2

we have
a5=a1r^4=1/24
evaluate r^4 or (1/2)^4
1/16
a1(1/16)=1/24
times both sides by 16/1
a1=16/24
a1=2/3

the first term is 2/3

One number is 16 more than another number. The two numbers have a sum of 120. Wbich system of equations could you use to find th
joja [24]

Step-by-step explanation:

Let, 1st number be x and 2nd number be y

Then,

equation 1

x = 16+y

equation 2

x + y = 120

or, y = 120 - x

now,

x = 16 + y

or, x= 16 + 120 - x (putting the value of y from equation 2 )

or, x + x = 136

or, 2x =136

or, x= 136/2

or, x =68

Then,

y = 120-x

or, y= 120- 68 (putting the value of x)

or, y= 52

Hence, the two numbers are 68 and 52.
