An Ap is such that 5 th term is three times the 2nd term.given further that the sum of the 5th,6th,7th,8th term is240,calculate
Fiesta28 [93]

Answer:

  5

Step-by-step explanation:

The general term of an arithmetic progression is ...

  an = a1 +d(n -1)

where a1 is the first term and d is the common difference.

Here we are given that ...

  a5 = 3×a2

  a5 +a6 +a7 +a8 = 240

__

In terms of a1 and d, these tell us ...

  a1 +d(5 -1) = 3(a1 +d(2 -1))

  a1 +4d = 3a1 +3d . . . . . eliminate parentheses

  d = 2a1 . . . . . . . . . . . subtract a1+3d

and ...

  (a1 +4d) +(a1 +5d) +(a1 +6d) +(a1 +7d) = 240

  4a1 +22d = 240

Substituting for d, we have ...

  4a1 +22(2a1) = 240

  48a1 = 240

  a1 = 240/48 = 5

The first term is 5.

Find the value of k, if (x - 2) is a factor of the polynomial p(x) = 2x2 + 3x - k​
Vesnalui [34]

Answer:

The value of k is 14.

Step-by-step explanation:

(x - 2) is a factor of the polynomial

x - 2 = 0 \rightarrow x = 2

This means that p(2) = 0

p(x) = 2x² + 3x - k​

p(2) = 2(2)^2 + 3(2) - k

0 = 8 + 6 - k

14 - k = 0

k = 14

The value of k is 14.
