Which sequence is generated by the function f(n + 1) = f(n) - 2 for f(1) = 10? ​

Answers

Answer:

The sequence generated will be 10,8,6,4,2,......

Step-by-step explanation:

We want to generate a sequence here

f(n + 1) = f(n) - 2

f(1) = 10

So f(2) = f(1) - 2 = 10 -2 = 8

f(3) = f(2) - 2 = 8-2 = 6

f(4) = f(3) -2 = 6-2 = 4

f(5) = f(4) - 2 = 4-2 = 2

So the sequence will be ;

Let’s assume the 147 freshman maintained a 65% attendance rate during the first 4 week of school. If our next 4 week goal for attendance is a 70%, how many more students would need to attend daily for the next 4 weeks.

Please Help ASAP

Answers

Answer:

12 students  

Step-by-step explanation:

If 65% equals 147

Then to maintain 70% there is a need for 5% more

Which equals

5*147/65 ≈ 12 students

Answer:

12 students

Step-by-step explanation:

147 maintained 65% attendance for the 1st 4 weeks

the goal is 70% on the next 4 weeks

ratio and proportion:

147 students =         x        

       65                     70      

65 (x) = 147 (70)

x = 10,290  

         65

x ≈ 159 students

therefore, the number of students would need to attend

                 daily for the next 4 weeks is

                 = 159 - 147

                 = 12 students

Alexandra has 36 coins valued at $6.00. She has only nickels and quarters. Which equation can be used to solve for the number of nickels, n?

0.05n + 0.25(36 – n) = 6
0.05n + 0.25(36 – n) = 36
n + 0.05 = 0.05n
n + (36 – n) = 36

Answers

Answer:A

Step-by-step explanation:

Answer:

Let n be the number of nickels and q be the number of quarters, then

n + q = 36 . . . (1)

0.05n + 0.25q = 6 . . . (2)

From (1): q = 36 - n . . . (3)

Putting (3) into (2) gives:

0.05n + 0.25(36 - n) = 6

What is the slope for Δy = 27, Δx = –8

Answers

Answer:

The slope is - 3 3/8

Step-by-step explanation:

Mathematically, we can calculate the slope m using the formula;

m = Δy/Δx

From the question;

Δy = 27 and Δx = -8

The slope will thus be;

m = 27/-8 = - 3 3/8
