Part A
Write the explicit formula in function form.
an = 5 +0.2(n - 1)
f(n) =

Part b
What is the y-intercept of the function​

Answers

Answer:

f(n) = 0.2n + 4.8

4.8

Step-by-step explanation:

Given the explicit formula :

an = 5 +0.2(n - 1)

Expressing an in function form f(n):

f(n) = 5 + 0.2(n - 1)

f(n) = 5 + 0.2n - 0.2

f(n) = 5 - 0.2 + 0.2n

f(n) = 0.2n + 4.8

The y - intercept :

Set n = 0

f(n) = 0.2n + 4.8

f(0) = 0.2(0) + 4.8

= 0 + 4.8

= 4.8

y intercept = 4.8

3.) Evaluate when y = -6
(y)2 + 2y + 5

Answers

Answer:

29

Step-by-step explanation:

I am going to assume (y)2 = [tex]y^{2}[/tex] because you have the term 2y right after.

when y = -6

[tex](-6)^2+2(-6) + 5 = 36-12+5\\= 29[/tex]

pheobe andy and polly share £270 pheobe gets three times as much as andy who hets twice as much as polly how much do they each get

Answers

Money of Phoebe - 3 times as much as Andy
Money of Andy - 2 times as much as Polly
Total money of Phoebe, - £270
Andy and Polly

*Solution

Let
B - Phoebe's money
A - Andy's money
L - Polly's money

1. The money of the Phoebe, Andy, and Polly, when added together would total £270. Thus,

B + A + L = £270 (EQUATION 1)

2. Phoebe has three times as much money as Andy and this is expressed as

B = 3A

3. Andy has twice as much money as Polly and this is expressed as

A = 2L (EQUATION 2)

4. This means that Phoebe has ____ as much money as Polly,

B = 3A
B = 3 x (2L)
B = 6L (EQUATION 3)

This step allows us to eliminate the variables B and A in EQUATION 1 by expressing the equation in terms of Polly's money only.

5. Substituting B with 6L, and A with 2L, EQUATION 1 becomes,

6L + 2L + L = £270
9L = £270
L = £30

So, Polly has £30.

6. Substituting L into EQUATIONS 2 and 3 would give us the values for Andy's money and Phoebe's money, respectively.

A = 2L
A = 2(£30)
A = £60

Andy has £60

B = 6L
B = 6(£30)
B = £180

Phoebe has £180

(M1219Q3SP) Um aplicativo de transporte de passageiros cobra uma taxa de R$ 0,75 por viagem, chamada de "Custo Fixo". Além dos R$0,75, a tarifa do aplicativo tem preço base inicial de R$2 e cobra R$1,40 por quilômetro rodado e R$ 0,26 por minuto de viagem. Considerando a distância percorrida em quilômetros igual a “q” e o tempo de viagem em minutos igual “t”, qual a função que representa o valor a ser cobrado por uma viagem usando esse aplicativo de transporte de passageiros é:

Mina opens a book 15 times and records whether the page number is
even or odd. How many trials did she conduct?

Answers

Answer:

She made 15 trials

Step-by-step explanation:

Well it said that she opened the book 15 times in total and records each time so the answer would be 15.

Mina conducted 15 trials in total.

What are trials? What is probability? In probability theory, an experiment or trial is any procedure that can be infinitely repeated and has a well-defined set of possible outcomes, known as the sample spaceThe formula to calculate the probability of occurrence of an event  [A] can be written as -  

       P(A) = n(A)/n(S)  

        where -

        n(A) = Number of outcomes favorable to event A.

        n(S) = Total number of outcomes.

We have Mina opens a book 15 times and records whether the page number is even or odd.

Since she opens the book 15 times, she conducted 15 trials in total.

Therefore, Mina conducted 15 trials in total.
