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

Answers

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.

Find the value of 9w + 1 given that -5w -5 = 5

Answers

Answer:

-17

Step-by-step explanation:

First, let's see what the value of w is, by solving -5w - 5 = 5.

-5w - 5 = 5            Add 5 on both sides.

-5w = 10                Divide -5 on both sides.

w = -2

Now, we know that w is equal to -2, let's plug it in to find the value.

9(-2) + 1                 Distribute.

-18 + 1                    Add.

Step-by-step explanation:

7m - 3 = 53

m would be 8 because 56 - 3 = 53.

11m + 2 equals 90 because 11 times 8 (8 is m) is 88, which added by two is 90.

F, because the circles are open

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.

entertainment. How many months will it take to save enough for Andrew to go to Santorini, Greece

Answers

Answer: 3 months

Step-by-step explanation:

Answer:

3 1/2 months (Someone please check my math)

Step-by-step explanation:

We can set up this problem by making an equation.

(2900-1200-200-5%)(x)=5000

(1500-5%)(x)=5000

(1425)(x)=5000

5000 divided by 1425 equals 3.50...

My answer would be 3 1/2 months but I could be wrong.

What is the solution of the system of linear equations graphed below?

Answers

Answer:  (1.125,-0.25)

Step-by-step explanation:  The point that is the same for both equations is the point where they intersect.  It appears from the graph to be around (1,0).  We should confirm this by deriving the equation for each line and then solving them.  Use the standard format:  y = mx+b, where m is the slope and b the y-intercept.

I calculate the 1st line (angled down to the right) to have a slope (m) of -2 [y drops 2 for every increase of 1 for x).  The y intercept is 2 (b).  This equation would be y = mx+b, or y = -2x + 2.

The second line has a positive slope of 2/3 and a y intercept of -1, y = (2/3)x-1

Set these two equations equal to each other and solve for x.

-2x+2=(2/3)x-1

x = 1.125

Use that value of x to solve for y:  y = -0.25

The point of intersection is therefore (1.125, -0.25)

| 7x-2 | +3 = -1 solve for x

Answers

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
