Answer:

Step-by-step explanation:

This question asks for the sum of the first 5 terms of the series.

Looking at the first 3 terms, we can see that each successive term is half of the one before it.

<em>So next term after 100 would be 50. Next term after 50 would be 25.</em>

Thus, we can write:

400 + 200 + 100 + 50 + 25 + ...

We already have first 5 terms, the sum is:

400 + 200 + 100 + 50 + 25 = 775

Answer choice B is right.

The correct answer is B) 775

Why 775? Because Assume the series continues.

400+200+100+50+25=775

I hope this helps.

Have a great day. :)

A train leaves the station at time = 0. Traveling at a constant speed, the train travels 330 kilometers in 3 hours. Answers part

Answer:

The function that relates the distance traveled d to the time t is

f(t) = 110t, where d = f(t)

Step-by-step explanation:

From the question, we were told that the train is At a constant speed, the train travels 330 kilometers in 3 hours

We were told to write function that relates the distance traveled d to the time t, we can do this by writing a linear equation with those functions

Since we are told that the train travels 330 kilometers in 3 hours, then we can say the train travel (330/3) kilometers in 1 hour which means it travel 110 kilometers in 1 hour

Then d= 110t---------------eqn(1)

If if t = 0, then d = 0, as well since at t=0 the train is at the station

At t = 1 then d = 110.

From equation (1) d can be replaced by f(t) then we have

f(t) = 110t----------------eqn(2)

Now we replace d by f (t), because d = f t):

f(t) = 120t

Therefore, The function that relates the distance traveled d to the time is f(t) = 120t
