kogti [31]

Answer:

$-8f(0) +4g(-8)=-32$

Step-by-step explanation:

Given

See attachment

Required

$-8f(0) +4g(-8)$

From the attachment;

$f(0) = 1$

and

$g(-8) = -6$

Substitute these values in $-8f(0) +4g(-8)$

$-8 * 1 + 4 * -6$

$-8 -24$

$-32$

Hence:

$-8f(0) +4g(-8)=-32$

Please help I’m very confused

Drupady [299]

Answer:

147

Step-by-step explanation:

The ∑ symbol means sum the term inside 4n + 1 from n = 2 to n = 8

Substitute n = 2, 3, 4, 5, 6, 7, 8 into the expression and sum the results , that is

4(2) + 1 + 4(3) + 1 + 4(4) + 1 + 4(5) + 1 + 4(6) + 1 + 4(7) + 1 + 4(8) + 1

= 9 + 13 + 17 + 21 + 25 + 29 + 33

= 147
