The sum of the arithmetic sequence given by
<span>an = 0.05(n – 1) – 0.6
will be given by:
a1=0.05(1-1)-0.6=-0.6
a2=0.05(2-1)-0.6=-0.55
a3=0.05(3-1)-0.6=-0.5
a4=0.05(4-1)-0.6=-0.45
a5=0.05(5-1)-0.6=-0.4
thus the summation will be:
-0.6+(-0.55)+(-0.5)+(-0.45)+(-0.4)
=-2.5
hence
S5=-2.5</span>
Answer:
Step-by-step explanation:
Given
Required
(a) Integrate
(b) Check using differentiation
To integrate, we make use of the following formula;
if
then
So; becomes
Take LCM
To check using differentiation, we make use of
if , then
Using this formula
becomes
So;
It would be 105,600 yards because if you multiply 1760 and 60 you’d get 105,600
