Answer:
Step-by-step explanation:
22/7x7^2=154
22/7x3^2=28(approx)
154-28=126
We have
AP = 34,36,38......,234
a, (first term) = 34
n ( total terms ) =?
d ( common difference ) = 2
so, a +(n-1)d =an
34+(n-1)*2 = 234
(n-1)2 = 234-34
n-1 = 200/2
n = 100+1
n =101
Now sum of the even no.
Sn = n/2( 2a+9n-1)d)
= 101/2 (2*34 +100*2)
= 101/2 * 268
=101 *134
= 13534
Answer:
All you need to do is find a common denomianatorand then solve from least to greatest hope this helps!

Answer:
Step-by-step explanation:
The exponential decay function is
where a is the initial value of the car, b is the rate of decay, and t is the time in years. Our rate of decay can also be written as (1 - r) where r is the depreciation in decimal form. Our equation looks like this:
which simplifies to
Now we can solve our problem for any number of years you'd like. We've been tasked to find the value of the car after 3 years, so:
which simplifies a bit to:
so
v(t) = 8043.57
