If you mean to the power of 3 the answer should be 0.421875
The answers are:
<span>ƒ(x) = x - .15x
</span><span>Sale = Original - .15(Original)
</span><span>y = .85x
Let sale price be f(x) and x be the original price. Discount was 15% = 0.15
f(x) = x - 0.15x
If f(x) is sale and x is the original, then:
</span><span>Sale = Original - .15(Original)
Let sale price be y and original price x:
y = x - 0.15x
y = 1 * x - 0.15 * x
y = (1 - 0.15) * x
y = 0.85x</span>

Answer:
7569.36
Step-by-step explanation:
Given that a quantity with an initial value of 7800 decays continuously at a rate of 0.1% per hour. What is the value of the quantity after 1.25 days,
First convert 1.25 days to hours
1.25 × 24 = 30 hours
Using exponential equation
N = No ( 1 - R% )^t
Where N = new value of the quantity
No = initial value
R = rate
t = time
N = 7800 ( 1 - 0.001 )^30
N = 7800 ( 0.999 )^30
N = 7800 × 0.97043
N = 7569.36154
N = 7569.36 to the nearest hundredth.
Therefore, the value of the quantity after 1.25 days is 7569.36
