On a word processing test, Iko typed 694 words in 15 minutes. On that same test six days later, Iko typed 753 words in 15 minute

Answer:

The improve in speed is 3.9334 words/min

Step-by-step explanation:

we will find speed at both occasions and then we can subtract them

First test:

total number of word =694

total time =15 min

we know that

speed = (total number of words)/( total time)

now, we can plug values

speed is

$=\frac{694}{15}$ word/min

$s_1=46.2666$ word/min

Second test:

total number of word =753

total time =15 min

we know that

speed = (total number of words)/( total time)

now, we can plug values

speed is

$=\frac{753}{15}$ word/min

$s_2=50.2$ word/min

So, improve in speed is

$=s_2-s_1$

$=50.2-46.2666$

$=3.9334$ word/min

What is a formula for the nth term of the given sequence? 50, -20,8...

Tatiana [17]

Answer:

L = 50 * (-0.4)^(n - 1)

Step-by-step explanation:

r = t2/t1 = -20/50 = - 0.4

a = 50

L = 50 * (r)^(n - 1) Let's see if we can get the answer when n = 3

L=50 * (-0.4)^(3 -1)

L =50* (-0.4)^2

L = 50 * 0.16

L = 8 which is correct
