Might have to experiment a bit to choose the right answer.

In A, the first term is 456 and the common difference is 10.  Each time we have a new term, the next one is the same except that 10 is added.

Suppose n were 1000.  Then we'd have 456 + (1000)(10) = 10456

In B, the first term is 5 and the common ratio is 3.  From 5 we get 15 by mult. 5 by 3.  Similarly, from 135 we get 405 by mult. 135 by 3.  This is a geom. series with first term 5 and common ratio 3.   a_n = a_0*(3)^(n-1).
So if n were to reach 1000, the 1000th term would be 5*3^999, which is a very large number, certainly more than the 10456 you'd reach in A, above.

Can you now examine C and D in the same manner, and then choose the greatest final value?  Safe to continue using n = 1000.

Shtirlitz [24]

Answer:

see explanation.

Step-by-step explanation:

2(10 * 4 * 7) is a surface area.

7 * 4 * 10 is volume.

2(10 * 4 + 10 * 7 + 4 * 7) is surface area.

10 + 4 + 7 is neither.

2 * 7 * 4 + 2 * 10 * 7 + 2 * 4 * 10 is neither.

hope this helps.

Describe how to draw a line that passes through the origin and has a slope of 3/5
ANEK [815]
The "origin" of a line is simply the points (0, 0)

To draw a line that passes through the origin (0, 0) & has a slope of 3/5, we simply start by drawing a point at (0, 0).

Then, from there, you use the slope to find your next points.

Slope = rise/run

So, 3 is the rise, and 5 is the run.

So, starting from (0, 0), you go up 3 times, and go to the right 5 times. So, (3, 5) is your next point. Just continue doing that and you'll get a line.

Camryn earns $198.60 per week. She works 15 hours each week. How much does Camryn earn per hour? P.S this is a unit rate questio
Musya8 [376]
Okay, so in order to find how much she earns per hour you'll take the salary she earns each week ($198.60) and divide that to how many hours she works every week (15 hours). It'll look like: 198.60 / 15= $13.24 per hour.
