A pendulum swings 80 cm on its first swing, 76 cm on its second swing, 72.2 cm on its third swing, and 68.59 cm on its fourth sw

Kisachek [45]

Answer:

$a_{n} = 80*(0.95)^{n-1}$

Step-by-step explanation:

Geometric sequences:

The nth term of a geometric sequence is given by the following equation.

$a_{n+1} = ra_{n}$

In which r is the common ratio.

This can be expanded for the nth term in the following way:

$a_{n} = a_{1}r^{n-1}$

In which $a_{1}$ is the first term.

In this question:

$a_{1} = 80, r = \frac{68.59}{72.2} = \frac{72.2}{76} = \frac{76}{80} = 0.95$

a. If the pattern continues, what explicit formula can be used find the distance of the nth swing?

$a_{n} = a_{1}r^{n-1}$

$a_{n} = 80*(0.95)^{n-1}$

| 2) through: (-5, -4), perp. to y = -x + 2

schepotkina [342]

Answer:

$y=x+1$

Step-by-step explanation:

Your generic line will be $y= mx+q$ , so you'll need two condition.

Since it has to be perpendicular to $y=(-1)x+2$ , the product of the slopes needs to be -1, or $m(-1)=-1$ , hence your "generic" becomes $y=x+q$ . Since it has to pass through [/tex](-5;-4), let's put the coordinates in there: $(-4)=1(-5)+qq-5=-4q=1$
