Answer:
For
;
, the function
would become
which is an exponential growth function. So, option D is correct.
Please check the attached figure a for visualizing the graph of
.
Step-by-step explanation:
As the function is given by
![f(x) = Pa^{x}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20Pa%5E%7Bx%7D)
For a function to be an exponential growth function
For a function to be an exponential decay function
For a function to have no change
If we carefully observe the choices, it is easy to determine that putting
;
in
would bring
.
So,
would be an exponential growth function. The graph of
is shown in<em> figure a</em>.
So, out of all the available options, only option D is correct i.e.
;
.

Answer:
10 feet
Step-by-step explanation:
Salvador has a rug in his bedroom with perimeter of 36 feet, the length of the rug is 8 feet what is the width of the rug?
The rug is shaped as a rectangle
The formula for the Perimeter of a rectangle = 2L + 2W
Perimeter = 36 feet
Length = 8 feet
Hence
36 = 2(8) + 2W
36 = 16 + 2W
2W = 36 - 16
2W = 20
W = 20/2
W = 10 feet
Therefore, the Width of the rug is 10 feet
Girs: boys = 7:5
42 : boys = 7: 5
42 : b = 7 : 5
42 / b = 7 / 5 Cross multiply
b*7 = 42 * 5
7b = 42* 5
b = 42*5/7 = 6*5 = 30
boys that participated are 30.

Step-by-step explanation:
?....
Small (x)
9(x) + 9(x) - 1 = 30
2 x 9(x) - 1 = 30
2 x 9(x) = 30 + 1
2 x 9(x) = 30
simplify
9x = 31/2
x = 1/2 x log (3) (31/2)
or
x ≈ 1.24741
