The values of the functions are:
1. y = f(-7) = 128
2. y = f(5) = 0.0313
<h3>How to Find the Value of a Function?</h3>
We can evaluate a function by substituting the given value into the equation of the function, then simplify.
Given the function, y = f(x) = (1/2) ^ x
1. Find the value of f(-7):
y = f(-7) = (1/2)^-7
y = f(-7) = 2^7
y = f(-7) = 128
2. 1. Find the value of f(5):
y = f(5) = (1/2)^5
y = f(5) = 0.0313

1) 100% - 30.2%=69.8%
The cost of the bracelet is 69.8% of the initial price.
2) $28170 ----- 100%
$ x ------ 69.8 %
x=(28170*69.8)/100 = 19662.66
Answer is $19662.66.
Step-by-step explanation:
Here with reference angle 45°
Hypotenuse ( h) = y
Perpendicular (p) = x
base (b) = 5√2
We know
tan 45° = p/b
1 = x / 5√2
Therefore x = 5√2
Now
h = √(5√2)^2 + 5√2)^2
= √ 50 +50
= √100
= 10
