Answer:
y = 0.2(0.5)^x
Step-by-step explanation:
Exponential function are of the form
y = ab^x
----------------------
To find "a" plug in x = 0 y = 0.2
0.2 = a(0.2)^0
0.2 = a
-------------------------
To find "b" plug in another point and a = 0.2
using x = 2, b = 0.05
0.05 = 0.2b^2
Divide both sides by 0.20
.25 = b^2
Take the square root of both sides
0.5 = b
-----------------------------
With a = 0.2 and b = 0.5 the equation becomes
y = 0.2(0.5)^x

Step-by-step explanation:
Answer:
Step-by-step explanation:
x -4 , 3x-11 , 5x - 18 ,.......
first term = a = x -4
Common difference (d) = second term - first term
= 3x -11 - [ x - 4]
= 3x - 11 - x + 4
= 3x - x - 11 + 4
= 2x - 7
nth term = a + (n-1)*d
12th term = x - 4 + 11*(2x - 7)
= x - 4 + 11*2x - 7 *11
= x - 4 + 22x - 77
=x + 22x - 4 - 77
= 23x - 81
