A sequence is recursively defined by f(1)=3,f(n)=2* f(n-1) for n >=2. Write the equation for the nth term

Answers

Answer 1

Given:

[tex]f(1)=3,f(n)=2\times f(n-1)[/tex]         ...(i)

For [tex]n\geq 2[/tex].

To find:

The nth term for the given recursive formula.

Solution:

The given recursive formula is of the form of

[tex]f(n)=r\times f(n-1)[/tex]            ...(ii)

It is the recursive formula of a GP, where r is common ratio.

On comparing (i) and (ii), we get

[tex]r=2[/tex]

Now,

First term: [tex]a=f(1)=3[/tex]

Common difference: [tex]r=2[/tex]

nth term of a GP is

[tex]f(n)=ar^{n-1}[/tex]

Putting a=3 and r=2, we get

[tex]f(n)=3(2)^{n-1}[/tex]

Therefore, the equation for the nth term is [tex]f(n)=3(2)^{n-1}[/tex].

The following section is a statement from the rental agreement Tim signed when he rented his car this past
weekend.
"Upon checkout, the fuel level of the vehicle will be determined by turning the vehicle on and visually inspecting the
fuel gauge. The approximate fuel level will be recorded on the Check-Out sheet and verified with initials by the
vehicle Renter. One copy of the Check-Out sheet will be given to the customer. Another copy will be kept with the
on-site records of the vehicle.
The rented vehicle must be returned with a minimum fuel level the same as that indicated on the Check-Out sheet.
A vehicle returned with a fuel level less than the approximate level indicated on the Check-Out sheet will be
completely refueled with on-site pumps. The price of the fuel used to refuel the vehicle will be added to the
Renter's total charge at a cost of $4.50 per gallon plus a S5.00 re-fueling charge
As a part of the check-out process, it is customary for a car rental agency to look over the car with the customer and
fill out the Check-Out sheet together. As Tim was walking around the car looking for damages that he didn't want to
be held responsible for, the agency representative turned on the car, took note of the fuel level, and indicated it on
the Check-Out sheet. Since Tim didn't have any questions, the clerk handed him the keys and a copy of the Check-
Out sheet and wished him well.

The expression 2a+3b gives the cost (in dollars) for a shirts and b pairs of pants at a garage sale. A. The cost for 1 shirt is $ and the cost for 1 pair of pants is $ . B. The total cost for 5 shirts and 5 pairs of pants is $ . Question 2 c. Is $20 enough to buy 7 shirts and 2 pairs of pants?

Answers

Answer:

Step-by-step explanation:

If 2a+3b gives the cost (in dollars) for a shirts and b pairs of pants at a garage sale

a) To get cost for 1 shirt and the cost for 1 pair of pants, we will substitute a = 1 abd b = 2 into the expression given

Cost = 2(1) + 3(2)

Cost = 2 + 6

Cost = $8

Hence cost for 1 shirt and the cost for 1 pair of pants is $8

b) For the total cost for 5 shirts and 5 pairs of pants;

a = 5 and b= 5

Cost = 2(5)+3(5)

Cost = 10 + 15

Cost = $25

Hence the total cost for 5 shirts and 5 pairs of pants is $25

c) To check whether $20 will be enough to buy 7 shirts and 2 pairs of pants, we will substitute a =  7 and b = 2 into the expression;

Cost = 2(7)+3(2)

Cost = 14 + 6

Cost = $20

Hence $20 will be enough to buy 7 shirts and 2 pairs of pants

Answer:

x=7

Step-by-step explanation:

This problem uses vertical angles! I'm sure you know this but just in case I will explain. Whenever there are two angles that are across from each other in a junction of two straight lines, they are perfectly equal! In this problem, the angles 6x-7 and 4x+7 are the same angle, so those equations have to have the same answer. In order to solve it, you need to write the equations like this:

6x-7=4x+7

From there you can solve for x. I will write my process here:

2x-7=7

2x=14

x=7

Just writing those vertical angle equations as equalities of each other should give you the answers you are looking for!

3, 25x< 4
5, x 24
9(2) =
g(-2) =
g(5) =

Answers

Answer:

I would, but the way this is set up is VERY confusing. sorry. maybe try to fix it after copying and pasting to make sure it makes sense.

The evaluated values of the step function for the given input values are as g(-2) = -4, g(2) = 3, and g(5) = 5.

To evaluate the step function g(x) for the given input values, we need to follow the conditions specified for each interval.

Given the step function:

g(x) =

-4, x < -1

-1, -1 ≤ x < 2

3, 2 ≤ x < 4

5, x ≥ 4

Let's evaluate the step function for each input:

g(-2):

Since -2 is less than -1, the condition for the first interval is satisfied. Therefore, g(-2) = -4.

g(2):

Since 2 is less than or equal to 4, the condition for the second interval is satisfied.  Therefore, g(2) = 3.

g(5):

Since 5 is greater than or equal to 4, the condition for the last interval is satisfied. Therefore, g(5) = 5.

Hence, we have:

g(-2) = -4

g(2) = 3

g(5) = 5

Step-by-step explanation:

find the equation of straight line passing through the points (a,0) and (0,b). If the point (1,1) lies on the equation, prove that
1/a + 1/b =1​

Answers

Answer:

do the following

Step-by-step explanation:

the question says that the line is passing thur the point 1,1 ... so when x = 1 so does y ... also  when  x= a.. then y=0 and when y=b then x =0  .. and this is a straight line... also  1/a + 1/b = 1

if you were to draw on a graph... this .. you would see that when b=2  then x=0 and also when a=2.. then y = 0  ....

and 1/2 + 1/2 =1

so that's the line.... draw in just roughly.... you'll see... then what is the equation of that line.. usually we would use  the slope intercept formula for the equations.. there are more than one way to show the line.. is my point.. but.. if we use  y = mx + b  where m = -1   and b = 2 then...

y= - x+2

That answer got long.. sorry :/

Answer:

step by step

Step-by-step explanation:

Line passing (a,0) (0,b)

slope = (y2 - y1) / (x2 - x1) = - b/a

pass (0,b), y interception: b

Line: y = -b/a * x + b  

pass(1,1) y=1, x=1

1 = -b/a + b  

1/b = (-b/a) /b + b/b

1/b = -1/a + 1

1/a + 1/b = 1

What is a compound interest?

"Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest."

Given, the annual profit of the company at first year = P =$277,000.

The rate of increase of profit = r% = 18% =0.18.

Total duration = n = 5.

Therefore, after first 5 years of operation, total profit the company would make = P[(1 + r)/100]ⁿ

= $277,000(1 + 0.18)⁵

=$633,708.9

≈$633,709

After 5 years , the total profit would have $633,709.

Answers

Answer:

The answer is 75 minutes.

Explanation :

Wednesday is 300 minutes & Tuesday is 225 minutes because 450 ÷ 2 = 225.

Wednesday is 300 minutes & Tuesday is 225 minutes because 450 ÷ 2 = 225. SO 300 - 225 = 75.

CAN YOU PLS GIVE ME BRAINLIST? THANK YOU! :))

Answer:

He worked for 75 more minutes on Wednesday then on Tuesday.

Step-by-step explanation:

So since we know that Matty worked for 450 minutes in his office on Monday, we can find out for how long he was working on Tuesday since we know that.......

Let "y" be the number of minutes Matty will work on Tuesday

Let "x" be the number of minutes Matty worked on Monday

[tex]y = \frac{x}{2}[/tex]

Substitute the values we have and get......

[tex]y = \frac{450}{2}[/tex]

[tex]y = 225[/tex]

So now we can find out how much more he worked on Wednesday then on Tuesday by doing the following......

Let "w" be the number of minutes Matty worked on Wednesday, then.......

The answer = [tex]w - y[/tex]

The answer = 300 - 225

The answer = 75
