Answer:
D. 154
Step-by-step explanation:
The area of the rectangle is 15*5= 75 inches
The area of the 2 semicircles combined, which make a circle, are:
π*r², where r is 5
r²=25
π*25=78.53981633
75 + 78.53981633 is about 154

Given:
The table of values of an exponential function.
To find:
The missing values in the exponential function.
Solution:
The general exponential function is defined as:
 ...(i)
              ...(i)
Where, a is the initial value and b is the growth factor.
First point from the given table is (1,10). It means, the equation (i) must be true for (1,10).
 ...(ii)
             ...(ii)
Second point from the given table is (2,20). It means, the equation (i) must be true for (2,20).
 ...(iii)
             ...(iii)
Dividing (iii) by (ii), we get


Putting  in (ii), we get
 in (ii), we get



Putting  in (i), we get
 in (i), we get

The required exponential function for the given table of values is  . So, the missing values are 2 and x, where 2 is in the base and x is in the power.
. So, the missing values are 2 and x, where 2 is in the base and x is in the power.
