A sequence has the recursive definition of f(1)=2/3, f(n)=f(n-1)×3/2 for n≥2
Right the first five terms of the sequence
Leave answers as fractions
Answer:
Step-by-step explanation:
[tex]f(1)=2/3\\f(2)=f(1)\times (3/2)=(2/3)\times(3/2)=1\\f(3)=f(2)\times (3/2) = 1\times (3/2) = 3/2\\f(4)=f(3)\times (3/2) = (3/2)\times (3/2) = 9/4\\f(5)=(f(4)\times (3/2) = (9/4)\times (3/2) = 27/8[/tex]
So the first five terms are 2/3, 1, 3/2, 9/4, 27/8.
The first five terms are 2/3, 1, 3/2, 9/4, and 27/8 if the f(1)=2/3, and f(n) = f(n -1)×(3/2); for n ≥ 2.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.
It is given that:
f(1)=2/3,
f(n) = f(n -1)×(3/2); for n ≥ 2
Plug n = 2
f(2) = f(2 -1)×(3/2)
f(2) = f(1)×(3/2)
f(2) = (2/3)(3/2)
f(2) = 1
Similarly;
f(3) = 3/2
f(4) = 94/
f(5) = 27/8
The first five terms are 2/3, 1, 3/2, 9/4, and 27/8.
Thus, the first five terms are 2/3, 1, 3/2, 9/4, and 27/8 if the f(1)=2/3, and f(n) = f(n -1)×(3/2); for n ≥ 2.

Answer:
Step-by-step explanation:
Domain means what is the lowest value of x on the graph and what is the highest. Our graph begins at an x value of -5 (but -5 is not included because the dot is not filled in) and goes all the way up to 2 (but 2 is not included either since the dot is not filled in. Therefore, the domain is
D = {x | x ∈ R, -5 < x < 2}
which means that the domain is in the set of real numbers that begin at -5 and end at 2, neither included.
Choice F is the one you want.

| 7x-2 | +3 = -1 solve for x
Answer:
x = -2/7 or
x = 6/7
Step-by-step explanation:
|7x-2| + 3 = -1 subtract 3 from both sides
|7x-2| = -4 now there are two probabilities
7x-2 = -4 or
7x-2 = 4 if first probability the value of x would be:
7x-2 = -4 add 2 to both sides
7x = -2 divide both sides by 7
x = -2/7 for the second probability the value of x would be:
7x-2 = 4 add 2 to both sides
7x = 6 divide both sides by 7
x = 6/7

Tom has a 20 yard long piece of rope. He cuts it into 1 ¾ yard pieces. What is the maximum number of pieces he can cut from the rope?
There are 11 3/7 pieces of rope which can cut from the rope.
What is Division method?
Division method is used to distributing a group of things into equal parts.
Given that;
Total length of rope = 20 yards
One piece = 1 3/4 = 7/4 yard
Now, Number of pieces of rope = 20 ÷ 7/4
= 80/7
= 11.43
= 11 and 3/7 pieces.
Thus, There are 11 3/7 pieces of rope which can cut from the rope.

if you make $391 for 17 hours how much would you make in 13 hours
Answer:
We would make $299 in 13 hours.
Step-by-step explanation:
Hi there!
We're given:
⇒ We make $391 in 17 hours
To find how much we make in 13 hours, we must first find how much we make in 1 hour. Divide $391 by 17 hours:
391 ÷ 17 = 23
Therefore, we make $23 in 1 hour.
Multiply $23 by 13 hours to find how much we would make in 13 hours:
23 × 13 = 299
Therefore, we would make $299 in 13 hours.

How much does the refrigerator cost?
Answer: $535
Step-by-step explanation
He will be able to buy the refrigerator with the amount he deposited ($500) plus the interest generated from it ($35)(which we get by doing the following):
So the formula for interest is
Interest = (principal ×interest rate × time for which the money was deposited) / 100
Interest = ?
Principal = $500
Interest rate = 7%
Time = 1 year
Now
Interest = (500 × 7 × 1) / 100
Interest = 3500/ 100
Interest = $35
So the refrigerater's cost = 500 + 35
Cost = $ 535

If 7m - 3 = 53. What is the value of 11m + 2?
Answer:
