Answer:
25
Step-by-step explanation:
Given the indicinal equation
5^-1/5^-3
According to one of the law of indices, if a, b, m and n are integers then;
a^m/a^n = a^(m-n)
When the base are equal, the powers will be subtracted.
Applying this formula to the given expression
5^-1/5^-3
= 5^{-1-(-3)}
= 5^(-1+3)
= 5^2
= 25
Therefore the answer is 25

Answer:
option D
0.5
Step-by-step explanation:
Formula to find the amplitude of function graph is
<h3>amplitude = maximum - minimum / 2</h3>
here maximum = 0.5
minimum = -.05
Plug values in the formula
amplitude = 0.5 - (-0.5) / 2
= 1 / 2
= 0.5
Secondly,
The amplitude of y=asin(x) and y=acos(x) represents half the distance between the maximum and minimum values of the function.
<h3>Amplitude = |a|</h3><h3>so,</h3>
y = .5cos6x
here a = 0.5
multiply $9 by 80%
80% = 0.80
9 * 0.8 = 7.20
subtract that from original price
9 - 7.20 = 1.80
Sale price is $1.80
