Identify the following for the exponential function y = 5(1/4)x.
a. Growth or decay?
b. Initial value
c. Growth/decay factor
d. Growth/decay rate (as a percentage)
Answer:
A)
Decay
B)
Initial value is 5.
C)
The decay factor is 0.75.
D)
75%
Step-by-step explanation:
An exponential function is given by:
[tex]f(x)=a(r)^x[/tex]
Where a is the initial value and r is the rate.
We have the function:
[tex]y=5(1/4)^x[/tex]
So, a = 5 and r = 1/4.
A)
Remember the guidelines:
It is exponential growth if r > 1. And it is exponential decay if r < 1. (And r must be positive.)Our rate is 1/4 or 0.25.
It is less than 1, so our function is exponential decay.
B)
The initial value is the value in front of our rate.
So, our initial value in this case is 5.
C)
The decay factor will be 1 - r, where r is our rate.
Since our rate is 0.25, our decay factor is 1 - 0.25 = 0.75.
So, we are decaying by a factor of 0.75.
D)
To convert a decimal to a percent, we move the decimal dot two places to the rght and add a percent sign.
So, 0.75 will be 75.0 % or smply 75%.
It is a 75% decay.

Answer:
4a. 13
4b. -4
Step-by-step explanation:
2x-6/5 = 4 (Muti each side by 5)
2x-6 = 20
2x = 26 (Divide each side by 2)
x = 13
7- 2x/4 = 9
-2x/4 = 2 (Muti each side by 4)
-2x = 8 (Divide each side by -2)
x = -4

Answer:
Correct answer: y>-32x-2
The required equation of inequality is y > - 3/2 x + 2.
We have given a graph of inequality for finding their equation.
What is inequality?
Inequality is a statement of an order relationship for greater than, greater than or equal to, less than, or less than or equal to, between two numbers or algebraic expressions.
From graph we can see that the line is passing through the points (0,-2) and (-4,4).
Since we know that the slope of a graph,
[tex]m = (y_2 - y_1)/(x_2 - x_1 )[/tex]
=[tex](4 - (-2))/(-4 - 0)[/tex]
⇒[tex]m = (-3)/( 2)[/tex]
Also we know the equation of line passing through the point (x_(1,) y_1) having slope be,
[tex]y - y_1 = m (x - x_1)[/tex]
Therefore, the equation of line passing through (0, -2) and having slope -3/2 be,
⇒ y - (-2) = - 3/2 x
⇒ y = - 3/2 x + 2
Since the graph is shaded left side to the line so, this equation can be written as
y > - 3/2 x + 2
Thus, this is the required equation of inequality.
