Answer:
37,191
Step-by-step explanation:
You would first use the arithmetic sequence, which is a_n=a_1+(n-1)(d). Since you already have your a1, d, and n figured out, all you need to do is find the a_n. So, you would plug in your values. You should get -3520 as your answer for this equation, or in this case a_n=-3520. The reason why it's negative is because your common difference was negative.
Next, you would use the equation Sn=n(a1+an)/2. You already have all of your variables solved, so now you just plug everything in. As the answer, you should get -1749. Make sure you do not subtract -3520. What I mean by this is don't make the negative a subtraction sign. Add the negative to the 22. Otherwise, you will get it wrong.
Hope this helps!

Answer:
on the second day it took them 6 hours to get to their grandparents' house
Step-by-step explanation:
First we have to calculate how many miles they had to drive the second day
For this we have to subtract from the total miles the number of miles they drove the first day
843 mi - 483 mi = 360 mi
To calculate the time it takes we have to divide the distance it has to travel by the average velocity at which they travel
v = 60 mi/h
d = 360 mi
t = d/v
t = 360(mi) / 60(mi/h)
t = 6 h
on the second day it took them 6 hours to get to their grandparents' house
Answer:
The answer is 800
Step-by-step explanation:
f(x) = 8(10)ˣ ; when f(2)
f(2) = 8(10)²
f(2) = 8 × 100
f(2) = 800
Thus, The answer is 800
