This information will be modeled using the formula
thus we shall have:
Sn=ar^n
where:
a=first term
r=common ratio
from the information:
a=30 ft
r=60/100=3/5=0.6
therefore the formula will be
Sn=30(0.6)^n
where n is the number of terms:
thus when n=5 th sum will be:
S5=30(0.6)^5
S5=30(0.6)^5
S5=2.33 ft
Answer: 2.33 ft
Step-by-step explanation:
this is you answer solved.
30/150 = 80/x
Reduce the fraction:
1/5 = 80/x
Cross multiply:
x = 5 x 80
x= 400
Answer: 400 zebras.
Given:
The equation of a function is
![y=(x-4)^2+1](https://tex.z-dn.net/?f=y%3D%28x-4%29%5E2%2B1)
To find:
The graph of the given function.
Solution:
The vertex form of a parabola is
...(i)
Where, (h,k) is vertex of the parabola.
We have,
...(ii)
From (i) and (ii), we get
![h=4, k=1](https://tex.z-dn.net/?f=h%3D4%2C%20k%3D1)
The vertex of the parabola is (4,1).
Now, the table of values is
x y
2 5
3 2
4 1
5 2
6 5
Plot these points on a coordinate plane and connect them by a free hand curve.
The graph of given function is shown below.
(8/9) / 6 =
8/9 * 1/6 =
8/54 which reduces to 4/27 of the book each day <===
