Answer:
Exponential decay function; -0.94%
Step-by-step explanation:
We are given an exponential function and we are supposed to find whether the given function increases or decreases and also the percentage of increase or decrease.
Th given function is f(x) = 2060
Here x denotes the number of years.
At the start the value was 2060. In the next year it was multiplied by 0.9906.
This means that the value becomes 0.9906 times after each year.
Hence the value decreases by 0.0094 times its original value.
Converting to percentage it becomes 0.94% decrease after each year.
Answer:
B. P(-4)=-144
Step-by-step explanation:
From the question, we have that:

This implies that:

To find p(-4), we put x=-4


To find p(0), we put x=0 to get:


The correct answer is B
Answer:
Step-by-step explanation:
Solution:
AM =( X_1 + X_2 )/2
=( 18 + 2 )/2
=20/2
=10
Find Geometric mean for data 18,2
Solution:
GM =sqrt( X_1 × X_2 )
=sqrt( 18 × 2 )
=sqrt(36)
=6
Answer:
Center is 
Step-by-step explanation:
Given: Equation of a circle is 
To find: center of the circle
Solution:
A circle is a locus of all points which are at equidistant from the fixed point (center).
Equation of a circle is of form
where
represents center of the circle and r denotes radius of the circle.
Given equation is 
![\left [ x-(-12) \right ]^2+(y-9)^2=35](https://tex.z-dn.net/?f=%5Cleft%20%5B%20x-%28-12%29%20%5Cright%20%5D%5E2%2B%28y-9%29%5E2%3D35)
Compare this equation with 
Center is
