The function of the brand new smartphone is an exponential function
The function that models the value of the phone x years after its puchase is f(x) = 1200(0.867)^x
How to model the function?The given parameters are:
Initial value (a) = $1200
Rate (r) = 13.3%
An exponential function that represents a decrement in value is illustrated using:
[tex]f(x) = a(1 - r)^x[/tex]
Substitute known values
[tex]f(x) = 1200(1 - 13.3\%)^x[/tex]
Evaluate the difference
[tex]f(x) = 1200(0.867)^x[/tex]
Hence, the function that models the value of the phone x years after its puchase is f(x) = 1200(0.867)^x

If you can type 50 words per minute, how many minutes would it take you to type a 500 word essay
==========================================
Work Shown:
A = 50 = number of words typed in 1 minute
B = 1 minute
C = 500 words
D = x minutes (needed to type 500 words)
A/B = C/D
50/1 = 500/x
50*x = 1*500 ... cross multiply
50x = 500
x = 500/50 .... divide both sides by 50
x = 10
You'll need 10 minutes to type 500 words
------------
Alternative approach:
50 words = 1 minute .... given speed
1 word = 1/50 minute ... divide both sides by 50
1 word = 0.02 minute
500 words = 10 minutes .... multiply both sides by 500
As per the given data, it would take approximately 10 minutes to type a 500-word essay at a typing speed of 50 words per minute.
If you have a typing speed of 50 words per minute, it means you can accurately type 50 words in one minute. This rate is often considered an average typing speed for proficient typists.
If I can type 50 words per minute, then to determine the number of minutes it would take to type a 500-word essay, we can divide the total number of words by the typing speed:
Time (in minutes) = Total words / Typing speed
Time = 500 words / 50 words per minute
Time = 10 minutes
Therefore, it would take approximately 10 minutes to type a 500-word essay at a typing speed of 50 words per minute.

RAVEL Four members of the Kaplan family will take a river trip down the Colorado River in Colorado State Park. The rafting company charges $10 per day to rent the raft and $15 per person for a half-day river trip, or $100 flat rate for a half-day river trip. The raft can hold up to 10 people. A. How much will the trip cost the Kaplan family at the per person rate? B. How many people must be on the river trip to make the flat rate less expensive than the per person rate?
Answer:
(a) $16.25
(b) 7
Step-by-step explanation:
Rent of 1 raft for 1 day= $10
So, rent for 1 raft for half-day=10/2=$5
Charge for 1 person for half-day river trip =$15
Flat rate for half-day river trip=$200
(a) There is 4 member of the Kaplan on the trip.
One raft can hold up to 10 people, so, they need to take 1 raft on rent.
Rent of 1 raft for half-day =$5
Charge for 4 persons for half-day river trip =$15x4=$60
Total cost for the half-day trip for 4 persons=5+60=$65
Cost for half-day trip for 1 person= $65/4=$16.25
(B) Let there are n peoples on the river trip.
For the number of people up to 10, they need to take one boat on rent.
Total per person cost=(Cost for rent of 1 boat for half-day)+( Cost for half-day river trip)
=5+15n.
Cost for flat rate= (Cost for rent of 1 boat for half-day)+( Flat rate cost)
=5+100
The condition for which the flat-rate cost is less expensive than the per person rate cost is
[tex]5+100<5+15n[/tex]
[tex]\Rightarrow 100<15n[/tex]
[tex]\Rightarrow n>\frac{100}{15}[/tex]
[tex]\Rightarrow n>6\frac{2}{3}[/tex]
As n is the number od person which cant be a fractional value, so
n=7,8,9,... or [tex]n\geq7[/tex]
So, a minimum of 7 people must be on the river trip to make the flat rate less expensive than the per person rate.

Step-by-step explanation:
y= -16 (total amount of meters below ground)
m= -1.5 (slope; meters he descends per minute)
x= 6 (minutes)
b= -7 (starting point)

A. Write the formula for the volume V of a prism where B is the area of the base and h is the height. V= b. Solve the formula for B. B= c. Use the new formula to find the area of the base of the prism. The area of the base of the prism is square inches.
Step-by-step explanation:
The question lacks the required diagram, find the diagram attached.
Volume of the pyramid V = BH where;
B is the base area
H is the height of the prism.
b) To solve for B, we will have to make B the subject of the formula from the equation in a;
From (a);
V = BH
Divide both sides by H
V/H = BH/H
V/H = B
B = V/H
c) Since we are not given the volume and height of the prism, we can as well use the following parameters;
Let us assume Volume of the prism = 175in³ and eight of the prism H = 5in
Substitute this values into the equation derived in (b)
B = 175in³/5in
Hence the area of the base of the prism is square inches is 35in²
