(b)The sum of n terms of a certain series is 3n² + 10n for all values
Angelina_Jolie [31]

Step-by-step explanation:

The nth term just mean how to work out the next number in he series. In this series of numbers, you have to square three n and add it onto 10 n to do this.

N is the term- the number it comes in the sequence.

Example:

2 3 4 5 6

2= the first terof the sequence

3= second term

4=3rd term

And so on

To work out what the next term is (6th term) you use this expression:

N+1

The first term is 2. As it is the first n=1. 1+1=2 so that works

The seco d term is 3. As it is the second term n=2. 2+1+3 so that works

And so on

This might help

But you have to do the rest

Answer:

  10 inches

Step-by-step explanation:

Use the formula for the area of a trapezoid. Fill in the given information and solve for the unknown.

  A = 1/2(b1 +b2)h

  50 in² = (1/2)(3 in +7 in)h

  50 in²/(5 in) = h . . . . . . . . . . divide by the coefficient of h

  10 in = h

The height of the trapezoid is 10 inches.

Each pound of potatoes costs $1 20 The total cost, in dollars,
PSYCHO15rus [73]

Answer:

$1.2

Step-by-step explanation:

Given the total cost, in dollars, given by the function c(p) = 1.2p.

If p = 1

c(1) = 1.2(1)

c(1) = $1.2

If p = 2

c(2) = 1.2(2)

c(2) = $2.4

If p = 3

c(3) = 1.2(3)

c(3) = $3.6

If p = 4

c(4) = 1.2(4)

c(4) = $4.8

Common difference = c2 - c1 = c3 - c2 = c4 - c3

Common difference = 2.4 - 1.2 =  3.6 - 2.4 = 4.8 - 3.6 = 1.2

Hence the common difference is $1.2
