Answer:
Geometric sequence
Step-by-step explanation:
According to the scenario, computation of the given data are as follows:
Leaves on tree this year (a) = 500
Rate of increase in leaves per year (r) = 40 % or 0.4
Let n be the number of years.
So we use exponential growth formula, i.e.
f(n) = a(1+r)^n
by putting the value, we get
f(n) = 500 ( 1+0.4)^n
or f(n) = 500 (1.4)^n
So, the common ration is 1.4.
Thus, it shows a geometric sequence.
To estimate this, round 53 to 50 and 12 to 10. 50 times 10 will be roughly what? 500. that is the estimated answer. the real answer is 636.
s = 71.6
____________
0.75 - 5/8s = 44
3/4 - 5/8s = 44
3/4 - 3/4 + 5/8s = 44 + 3/4
5/8s = 44 3/4
5/8s / 5/8 = 44 3/4 / 5/8
s= (179/4 / 5/8)
s= (179/4 * 8/5)
s= (179/1 * 2/5)
s= (358/5)
s= (350/5 + 8/5)
s= (70 + 8/5)
s= (70 + 1 + 3/5)
s= 71 3/5
s= 71.6
I checked this and its correct :P Sorry about the late answer, hope this helps!
