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

your line becomes y=x+1

Write 320 g as a fraction of 2 kg. Give your answer in its simplest form.
Kitty [74]

Answer:

4/25

Step-by-step explanation:

Let's make the units the same :

2 kg = 2000 g

Now lets simplify this fraction :

Divide top and bottom by 2 until you can't :

320/2000 = 160/1000

160/1000 = 80/500

80/500 = 40/250

40/250 = 20/125

Now we divide top and bottom by 5 as 2 is not a factor of 125 :

20/125 = 4/25

This is our final answer

Hope this helped and brainliest please
