Cecelia studied for the sat for 20 minutes every day in the first week, 30 minutes in the second week, 40 minutes in the third week, and 50 minutes in the fourth week.
christopher studied for the sat for 5 minutes every day in the first week, 10 minutes in the second week, 20 minutes in the third week, and 40 minutes in the fourth week.
which statement best describes the methods used by cecelia and christopher to increase the time they spent studying?
a. cecelia's method is exponential because the number of minutes increased by an equal number every week.
b. christopher's method is exponential because the number of minutes increased by an equal factor every week.
c. both christopher's and cecelia's methods are linear because the number of minutes increased by an equal factor every week.
d. both christopher's and cecelia's methods are linear because the number of minutes increased by an equal number every week.

Option B.

Step-by-step explanation:

Cecelia studied for the SAT for 20 minutes every day in the first week, 30 minutes in the 2nd week, 40 minutes in 3rd week and 50 minutes in 5th week.

So the sequence formed is 20, 30, 40, 50

This sequence has a common difference of

Therefore, this sequence is an arithmetic sequence or linear sequence.

Christopher studied for the SAT for 5 minutes every day in the first week, 10 minutes in 2nd week, 20 minutes in 3rd, 40 minutes in 4th week.

Sequence formed is 5, 10, 20, 40.

It's an exponential or geometric sequence which has a common ratio

r =

 =

Therefore, Option B will be the answer.

i'm not sure what you mean but in todays world there is a lot of women that are the bread winners in the family. there is a lot more single mothers now that are going back to get an education which is boosting the economy. i believe there has been a boost in the economy due to women the cosmetic industry is boosting, chemist, the sky is becoming the limit for women in todays economy. most women are also putting off having kids just to make sure they have a education. i don't know how these two relate though to scriptures because it's not the way the lord wanted it. the man is suppose to be the bread winner and due to social media and the easy access we have there is a lot of cheating going on.
