Write the first five terms of the sequence in which the nth term is
ziro4ka [17]

Answer:

C) 2,6,24,120,720

Step-by-step explanation:

Here the n-th term An = \frac{(n +2)!}{n + 2}

A1 is the first term

A1 = (1 + 2)!/(1 + 2)

= 3!/3

A1 = 2

A2 is the second term

A2 = (2 +2)!/(2 +2)

= 4!/4

A2 = (1*2*3*4) /4

A2 = 6

A3 is the third term

A3 = (3 + 2)!/(3 +2)

A3 = 5!/5

A3 = 24

A4 is the fourth term

A4 = (4 + 2)!/(4 + 2)

A4 = 6!/6

A4 = 120

A5 is the fifth term

A5 = (5 + 2)!/(5 +2)

A5 = 7!/7

A5 = 720

Answer: C) 2,6,24,120,720

I need help someone please
statuscvo [17]

Answer: \frac{6}{2}

Step-by-step explanation:

1. Use this \frac{f(b)-f(a)}{b-a} to find the average rate of change

2. Average rate of change = \frac{f(8)-f(6)}{8-6}

3. f(8) = - 4 and f(6) = -10 (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))

4. Replace -4 to f(8) and -10 to f(6)

5. So it will look like\frac{-4-(-10)}{8-6}

6. Solve \frac{6}{2}

Hey there!


For this problem you need to replace x with 45

So the new problem is 2(45)+4

2 x 45 = 90
then 90+4 = 94

Your answer is 94

Hope I was able to help!
