Question

is this a @Preetha @confluxepic @CausticSyndicalist @mathmath333

Answer 1

Amanda exercised for 10 minutes every day in the first week, 20 minutes in the second week, 30 minutes in the third week, and 40 minutes in the fourth week.

Billy exercised 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 Amanda and Billy to increase the time they spent exercising?

Amanda's method is linear because the number of minutes increased by an equal number every week.
Billy's method is linear because the number of minutes increased by an equal factor every week.
Both Billy’s and Amanda's methods are exponential because the number of minutes increased by an equal factor every week.
Both Billy’s and Amanda's methods are exponential because the number of minutes increased by an equal number every week.

Answer 3

Linear is kind of when the difference between the intervals is a consistent number
like the progression of 15, 25, 35, 45 is linear because it increases by 10 each time.

Exponential is kind of when there's a pattern but the first layer of intervals are not a consistent number.
for example: 2, 4, 8, 16 increases differently each time (so it's not linear) but you can tell that the numbers are doubling (which has a pattern) so it is exponential

Answer 4

ok thank you

Answer 5

is the answer a @jigglypuff314

Answer 6

I think so :)

Answer 7

Jake has proved that a function, f(x), is a geometric sequence. How did he prove that?

He showed that an explicit formula could be created.
He showed that a recursive formula could be created.
He showed that f(n) ÷ f(n - 1) was a constant ratio.
He showed that f(n) - f(n - 1) was a constant difference.
