Answer:
[tex]y=32500(0.86)^{x}[/tex]
Step-by-step explanation:
General exponentially depreciating function is given as
[tex]y= a(1-b)^{x}[/tex]------------(1)
Where a is initial value, b is percent depreciation/unit time and x is time
Here
[tex]a=32,500 \ \ \ b=0.14 \ \ \ and \ \ x \ is \ time \ in \ years[/tex]
Substituting above values in equation (1)
[tex]y=32500(0.86)^{x}[/tex]
At x=0
[tex]y=32500(0.86)^{0}\\y=32500[/tex]
At x=1
[tex]y=32500(0.86)^{1} \\y=27950[/tex]

Answer:
x = [tex]\sqrt{30}[/tex]
Step-by-step explanation:
Using the Altitude- on- Hypotenuse theorem
(leg of Δ ABC )² = (part of hypotenuse below it ) × ( whole hypotenuse )
x² = 3 × (3 + 7) = 3 × 10 = 30 ( take the square root of both sides )
x = [tex]\sqrt{30}[/tex]
Adam drops a ball from a height of 12 feet. Each bounce is 50% as high as the previous bounce. What

The function f is given by
f(x) = x² – 2x
Which statement is true about the graph of f ?
The x-intercept of the function are at (0, 0) and (2, 0). Then the correct option is D.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The function f is given by f(x) = x² – 2x.
f(x) = 0
On factorization, we have
x² – 2x = 0
(x – 2)x = 0
x = 0, 2
For x = 0, the function f(x) will be
f(x) = 0² – 2(0)
f(x) = 0
For x = 2, the function f(x) will be
f(x) = 0² – 2(2)
f(x) = 4 – 4 = 0

The driving distance between Manchester and london is 195 miles. Fairs intends to travel from Manchester to London by coach. The coach will leave Manchester at 3:30pm. Faris assumes that the coach will travel at an average speed of 50mph. Using his assumption work out faris's arrival time in London. It actually turns out that the coach has a lower average speed describe how this affects the arrival time.
Answer:
7:24 pm
Time taken will be longer
Step-by-step explanation:
Given that:
Distance between Manchester and London = 195 miles
Departure time = 3.30 pm
Average speed of Coach = 50 mph
Arrival time in London :
Time taken = distance / speed
Time taken = 195 / 50 = 3.9 hours (3 hours (0.9 * 60) = 3 hours 54 minutes
= 3:30 pm + 3 hours 54 minutes = 7:24 pm
If the speed is Lower then the Timetaken will be longer and subsequently coach will arrive after 7:24 pm
