F(n)=45⋅(4/5)^n−1 complete the recursive formula of f(n)

Mathematics
1 answer:
Radda [10]3 years ago
7 0

F(1) = 45

f(n) = f(n-1) * 4/5

Step-by-step explanation:

f(n) = 45 x (4/5)ⁿ⁻¹

f(1) = 45 x (4/5)¹⁻¹ = 45 x (4/5)⁰ = 45 x 1 = 45

f (n-1) = 45 x (4/5)ⁿ⁻¹⁻¹ = 45 x (4/5)ⁿ⁻²

f(n) = f(n-1) * (4/5)¹ = 45 x (4/5) ⁿ⁻²⁺¹ = 45 x (4/5)ⁿ⁻¹

To make this problem easier you could make the denominators equal to combine the 2 bills to see how of his paycheck is being used already. to 2/7 = 6/21 and 1/3=7/21 so with 6/21 and 7/21 you can combine them and you have 13/21 is used on bills so 21/21(which represents the whole paycheck) - 13/21 =8/21 so 8/21 is what is left his paycheck to spend write this as a decimal by dividing and you will have the percentage that he has left  so 8/21 = .38 so he can spend approximately 38% of his check on games and 63dollars * .38 is about 24dollars 63*.38 =24(approximately) you divide 8/21 and get an exact answer.

The weights for newborn babies is approximately normally distributed with a mean of 5.4 pounds and a standard deviation of 1.8 p
Mariana [72]

Answer:

You would expect 807 babies  to weigh between 3 and 6 pounds.

Step-by-step explanation:

We are given that

Mean,\mu=5.4pounds

Standard deviation,\sigma=1.8pounds

n=1500

We have to find how  many would you expect to weigh between 3 and 6 pounds.

The weights for newborn babies is approximately normally distributed.

Now,

P(3

=P(-1.33

P(3

P(3

P(3

Number of newborn  babies expect to weigh between 3 and 6 pounds

=1500\times 0.538=807

Which of the binomials below is a factor of this trinomial? -3x^2-21x+24 x-4 x+1 x+4 x-1
OleMash [197]

Answer:

-3x^2-21x+24

Step-by-step explanation:

Kindly separate the answer choices:  (x - 4), (x + 1), (x + 4) , (x - 1).  The trinomial is thus -3x^2-21x+24, which can be factored as follows:  -3(x^2 + 7x - 8)

Then we have -3x^2-21x+24 = -3(x^2 + 7x - 8), which factors further into:

-3(x + 8)(x -1)  and so we conclude that the only binomial that is a factor of

-3x^2-21x+24 is (x - 1).
