Determine 4th term in the geometric sequence whose first term is -2 and whose common ration is -5.

anygoal [31]

Answer:

$a_{4}$ = 250

Step-by-step explanation:

To obtain any term in the geometric sequence multiply the previous term by the common ratio r

here r = - 5 and $a_{1}$ = - 2, hence

$a_{2}$ = - 2 × - 5 = 10

$a_{3}$ = 10 × - 5 = - 50

$a_{4}$ = - 50 × - 5 = 250

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by

Alja [10]

Answer:

The numbers of measure of music played are 1 and 7

Step-by-step explanation:

Given

$s = 10|x - 4| + 50$

Required

Solve for x when s = 80

Substitute 80 for x

$80 = 10|x - 4| + 50$

Subtract 50 from both sides

$80 - 50= 10|x - 4| + 50 - 50$

$30= 10|x - 4|$

Divide through by 10

$\frac{30}{10}= \frac{10|x - 4| }{10}$

$3= |x - 4|$

Reorder

$|x - 4| = 3$

This can be split into

$x - 4 = 3$ or $x - 4 = -3$

Solve for x

$x = 4 + 3$ or $x = 4 - 3$

$x = 7$ or $x = 1$

Hence:

<em>The numbers of measure of music played are 1 and 7</em>
