Answer:
100th term = -1485
Step-by-step explanation:
<h3>Arithmetic Progressionthe </h3><h3>nth term, Tn:</h3>
n = number of terms
= 100
a = first term
= 5
d = difference
= second term - first term
= 2 - 5
= -3
substitute the values into the formula
Answer:
Step-by-step explanation:
x^2 + 7x + 5x + 35
7x : II
5x: III
35: IV
Let after t hours the distances D1 traveled by car A
D1 = 30 t
Car B starts at 10 am and will therefore have spent one hour less than car A when it passes it.
After (t - 1) hours, distance D2 traveled by car B
D2 = 40 (t - 1)
When car B passes car A, they are at the same distance from the starting point and therefore<span> D1 = D2 </span>
30 t = 40 (t - 1)
Solve the equation for t,
30 t = 40t - 40
10 t = 40
t = 4
<span> Car B passes car A at = 9 + 4 = 1 pm.</span>
4 is 1/15 for 1 6/20 for 2 3/20 for 3 1/10 for 4 3/10 for the last on
