Alfred is practicing typing. the first time he tested himself, he could type 30 words per minute. after practicing for a week, he could type 33 words per minute. after two weeks he could type 36 words per minute. based on this pattern, predict how fast alfred will be able to type after four weeks of practice.

42 words per minute

Step-by-step explanation:

Weeks(x)          Words per minute(y)

0                              30

1                               33

2                              36

To find the function we will use two point slope form.

  ---A

Substitute the value in A

Thus the equation represents the situation :

Where y is the words per minute

x is the number of weeks

Now we are supposed to find how fast Alfred will be able to type after four weeks of practice.

Substitute x = 4

Hence Alfred will be able to type 42 words per minute after four weeks of practice.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
