Make 1 1/5 into improper fraction which is 6/5 and then find the common denominator 6/5 and 5/8.
Common denominator is 40. Multiply 8 by 6 and 8 by 5 so it would become 48/40. Do the same with 5/8 except multiply by 5 which would be 25/40. Subtract 48/40 and 25/40 which is.....
23/40
The area of the shaded regions is: 44π
<h3>What is the Area of a Circle?</h3>
Area of a circle where "r" is the radius is determined using the formula: πr².
The figure given has three circles, namely:
- Circle A with radius of 8 cm.
- Circle B with radius of 4 cm.
- Circle C with radius of 2 cm.
The area of the shaded regions = <em>Area of circle A - Area of Circle B + Area of Circle C</em>
Area of Circle A = (π)(8)² = 64π
Area of Circle B = (π)(4)² = 16π
Area of Circle C = (π)(2)² = 4π
Thus:
The area of the shaded regions = 64π - 16π + 4π
The area of the shaded regions = 44π

Answer:
7/4 or 1 3/4
Step-by-step explanation:
Given:
The graph of an exponential function.
To find:
The exponential growth factor as x increases by 1 unit.
Solution:
From the given graph, it is clear that the exponential function passes through the points (1,1) and (3,9). So, the equation of the exponential must must be satisfy by these points.
The general exponential function is:
...(i)
Where, a is the initial value and b is the growth factor.
Putting
in (i), we get
...(ii)
Putting
in (i), we get
...(iii)
Divide (iii) by (ii).



b is the the growth factor and the value of b is 3.
Therefore, the exponential growth factor is 3 as x increases by 1 unit.
