If the sixth term in a geometric sequence is 1/625, and the common ratio is 1/5, find the explicit formula of the sequence.
Question 21 options:
an=(15)n−1for n ≥ 1
an=(5)⋅(15)n−1for n ≥ 2
an=(1)⋅(15)n−1for n ≥ 2
an=(5)⋅(15)n−1for n ≥ 1
Answer:
aₙ = 5*(1/5)^(n - 1)
Step-by-step explanation:
The recursive relation for a geometric sequence is:
aₙ = aₙ₋₁*R
where R is the common ratio.
We could write this in a general form as:
aₙ = a₁*(R)^(n - 1)
where a₁ is the first term of the sequence.
In this case we know that:
R = 1/5
And that:
a₆ = 1/625
Then we can replace these values in the above relation to get:
a₆ = (1/625) = a₁*(1/5)^(6 - 1) = a₁*(1/5^5) = a₁*(1/3125)
1/625 = a1*(1/3125)
(3125/625) = a1 = 5
Then the formula will be:
aₙ = 5*(1/5)^(n - 1)

What is the size of the exterior and interior angle of a regular polygon if it has 3 sides
Answer:
120° and 60°
Step-by-step explanation:
The sum of the exterior angle of a polygon is 360°, then
exterior angle = 360° ÷ 3 = 120°
The exterior and interior angle sum to 180°, then
interior angle = 180° - 120° = 60°

Can somebody explain how to do this quickly. Already know how to solve it but it takes me a long time
Answer:
n = 8Step-by-step explanation:
Initial point: (1, -2)
Final point: y = x
Blue light translation:
4 units right, 5 units downNumber of translations = nRed light translation:
1 unit left, 4 units upNumber of translations = 15Final point is going to be:
x = 1 + 4n - 15*1 = 4n - 14y = -2 - 5n + 15*4 = -5n + 58Since the coordinates of final point are same, we have:
4n - 14 = -5n + 584n + 5n = 58 + 149n = 72n = 72/9n = 85. The weight of 1 bag of sugar is 12.5 kg. What is the weight of 15 such bags?

Find the length of AB PLEASE HELP
Answer: D) 53.74
This value is approximate.
===========================================
Work Shown:
x = length of AB
Use the sine rule to say
sin(angle) = opposite/hypotenuse
sin(B) = AC/AB
sin(61) = 47/x
x*sin(61) = 47
x = 47/sin(61)
x = 53.7376 ..... make sure your calculator is in degree mode
x = 53.74
So AB = 53.74 approximately

Alex rents a car for one day. The charge is $18 plus $0.12 per mile. Alex wants to spend exactly $30. Write an equation to represent the situation.
A) 30 - 0.12 = 18x
B) 18 + 0.12x = 30
C) 18 - 0.12x = 30
D) 18x + 0.12 = 30
please help
Answer:
B)
Step-by-step explanation:
Because it says that Alex wants to spend exactly $30 so you want to have 30 as the total ( = 30 )
and it says 18 plus, you only add 18 one time ( 18 + )
and then it says 0.12 per mile, so you need to do something times 0.12 + 18 and get exactly 30. so you do ( 0.12x ) in this case we're not solving it we're just doing the equation so it's just 0.12x instead of a specific number
Put it all together and you get 18 + 0.12x = 30

A person places $1380 in an investment account earning an annual rate of 8.6%,
compounded continuously. Using the formula V = Pent, where Vis the value of the
account int years, P is the principal initially invested, e is the base of a natural
logarithm, and r is the rate of interest, determine the amount of money, to the
nearest cent, in the account after 10 years.
Answer:
3261.16
Step-by-step explanation:
r=8.6\%=0.086
r=8.6%=0.086
Move decimal over two places
P=1380
P=1380
Given as the pricipal
t=10
t=10
Given as the time
V=Pe^{rt}
V=Pe
rt
V=1380e^{0.086( 10)}
V=1380e
0.086(10)
Plug in
V=1380e^{0.86}
V=1380e
0.86
Multiply
V=3261.1618\approx 3261.16
V=3261.1618≈3261.16
