When introduced in 1997, a DVD player sold for about $500. Five years later, the average price was $155. Find and interpret the average rate of change in price per year.
Answer:
-69
Step-by-step explanation:
Use rise over run (change in y/change in x)
The change in y is -345, since that is how much the price decreased
The change in x is 5 years
-345/5
= -69
So, the average rate of change in price per year is -69
Which Set Of Numbers Does √35 Belong?
Answer:
rational
Step-by-step explanation:
What is the inverse of the function
Answer:
1/2x -1/2
Step-by-step explanation:
f(x) = 2x+1
y = 2x+1
Switch x and y
x = 2y+1
Solve for y
Subtract 1
x-1 = 2y+1-1
x-1 =2y
Divide by 2
(x-1)/2 = 2y/2
1/2x -1/2 = y
The inverse is 1/2x -1/2
Answer:
[tex]\huge\boxed{h(x) = \frac{1}{2} x - \frac{1}{2}}[/tex]
Step-by-step explanation:
[tex]f(x) = 2x+1[/tex]
Put f(x) = y
[tex]y = 2x + 1[/tex]
Interchange x and y
[tex]x = 2y+1[/tex]
Solve for y
[tex]x = 2y+1[/tex]
Subtracting 1 to both sides
[tex]x-1 = 2y[/tex]
Dividing both sides by 2
[tex]\frac{x-1}{2} = y \\\\ OR\\\\ y = \frac{x-1}{2}[/tex]
Put y = h(x)
[tex]\bold{h(x) = \frac{1}{2} x - \frac{1}{2}}[/tex]

A species of fish was added to a lake. The population size Pt of this species can be modeled by the following function, where t is the number of years from the time the species was added to the lake. P(t) = 1000+(12e^−0.34t)where t is the number of years from the time the species was added to the lake.
Find the initial population size of the species and the population size after 9 years. Round your answers to the nearest whole number as necessary.
Answer:
1,012 ; 1,001
Step-by-step explanation:
Given the population function :
P(t) = 1000+(12e^−0.34t)
where t is the number of years from the time the species was added to the lake.
Initial population size of the species ; that is the population at year 0
At time, t = 0
P(0) = 1000+(12e^−0.34(0))
= 1000 + (12e^0)
= 1000 + 12(1)
= 1012
Initial population = 1,012
Population after 9 years :
P(9) = 1000+(12e^−0.34(9))
= 1000 + (12e^-3. 06)
= 1000 + (12×0.0468876)
= 1000 + ( 0.5626523)
= 1000.5626
= 1001 ( nearest whole number)

Answer:
The median number of shirts sold is 29
Step-by-step explanation:
Order the number from least to greatest (in this case they already are), then take the middle number or the two middle number if you have to numbers in the middle. If you have to numbers in the middle add them and the divide by 2.
27+31=58
58÷2=29
Answer:29
Step-by-step explanation:
First find the two middle numbers in this case 27 and 31 add them together and divide by 2

Jordan uses three lemons to make 1 pitcher of lemonade. He makes 4 pitchers. How many lemons does he use altogether? *What visual would you use to draw this story problem?
Answer:
The number of lemons Jordan uses to make the 4 pitcher of lemonade is 12 lemons
Step-by-step explanation:
The number of lemons the Jordan uses to make 1 pitcher of lemonade = three lemons
The number of pitcher lemonades Jordan makes = 4 pitcher of lemonades
The number of lemons Jordan uses altogether, is given by the following relation;
1 pitcher of lemonade = 3 lemons
4 pitcher of lemonades = 4 × 3 lemons = 12 lemons
Therefore, the number of lemons Jordan uses to make the 4 pitcher of lemonade is 12 lemons.
A parking attendant charges a different rate for cars than for trucks. It costs $10.75 to park 3 cars and 2 trucks. It costs $12.25 to park 7 cars and 1 truck. How much does it cost to park a single car? A single truck?
Answer:
$1.25 to park a car and $3.50 to park a truck
Step-by-step explanation:
Set up a system where c is the number of cars parked and t is the number of trucks:
3c + 2t = 10.75
7c + t = 12.25
Solve by elimination by multiplying the bottom equation by -2 to eliminate t:
3c + 2t = 10.75
-14c - 2t = -24.5
Add them together and solve for c:
-11c = -13.75
c = 1.25
Then, plug in 1.25 as c in the equation to solve for t:
3c + 2t = 10.75
3(1.25) + 2t = 10.75
3.75 + 2t = 10.75
2t = 7
t = 3.5
So, it costs $1.25 to park a car and it costs $3.50 to park a truck
If PR = 25 and PQ = 12, then QR=
Answer:
QR= 13
Step-by-step explanation:
the points on the line in order from left to right are P, Q, R, which means that the distance from P to R is the length of the line. So PQ is only about half the line. To solve this question you would subtract 12 from 25:
25-12=13
hope that helps. can i have brainliest?
Answer:
It depends on whether P lies on QR or not.
If not, we can't find the exact answer for this question.
If P does, there are 2 cases:
Case 1: P is between Q and R
so QR = PQ + PR = 12 + 25 = 37
Case 2: Q is between P and R (because PQ < PR so there is no likelihood for R to lie betweem P and Q)
so QR = PR - PQ = 25 - 12 = 13

In the drawing above two rugby players start 41 meters apart at rest. Player 1 accelerates at 2.2 m/s^2 and player 2 accelerates at 1.7 m/s^2. How much time elapses before the players collide?
Answer:
The time that elapses before the players collide is 4.59 secs
Step-by-step explanation:
The distance between the two players is 41 meters. Hence, they would have total distance of 41 meters by the time they collide.
We can write that
S₁ + S₂ = 41 m
Where S₁ is the distance covered by Player 1 before collision
and S₂ is the distance covered by Player 2 before collision
From one of the equations of kinematics for linear motion,
[tex]S = ut[/tex] + [tex]\frac{1}{2} at^{2}[/tex]
Where [tex]S[/tex] is distance
[tex]u[/tex] is the initial velocity
[tex]a[/tex] is acceleration
and [tex]t[/tex] is time
Since the players collide at the same time, then time spent by player 1 before collision equals time spent by player 2 before collision
That is, t₁ = t₂ = t
Where t₁ is the time spent by player 1
and t₂ is the time spent by player 2
For player 1
[tex]S[/tex] = S₁
[tex]u[/tex] = 0 m/s ( The player starts at rest)
[tex]a[/tex] = 2.2 m/s²
Then,
S₁ = [tex]0(t)[/tex] + [tex]\frac{1}{2} (2.2)t^{2}[/tex]
S₁ = [tex]1.1t^{2}[/tex]
[tex]t^{2} = \frac{S_{1} }{1.1}[/tex]
For player 2
[tex]S[/tex] = S₂
[tex]u[/tex] = 0 m/s ( The player starts at rest)
[tex]a[/tex] = 1.7 m/s²
Then,
S₂ = [tex]0(t)[/tex] + [tex]\frac{1}{2} (1.7)t^{2}[/tex]
S₂ = [tex]0.85t^{2}[/tex]
[tex]t^{2} = \frac{S_{2} }{0.85}[/tex]
Since the time spent by both players is equal, We can write that
[tex]t^{2}[/tex] = [tex]t^{2}[/tex]
Then,
[tex]\frac{S_{1} }{1.1} = \frac{S_{2} }{0.85}[/tex]
[tex]0.85S_{1} = 1.1S_{2}[/tex]
From, S₁ + S₂ = 41 m
S₂ = 41 - S₁
Then,
[tex]0.85S_{1} = 1.1 ( 41 -S_{1} )[/tex]
[tex]0.85S_{1} = 45.1 - 1.1S_{1}[/tex]
[tex]0.85S_{1} + 1.1S_{1} = 45.1 \\1.95S_{1} = 45.1\\S_{1} = \frac{45.1}{1.95} \\S_{1} = 23.13 m[/tex]
This is the distance covered by the first player. We can then put this value into [tex]t^{2} = \frac{S_{1} }{1.1}[/tex] to determine how much time elapses before the players collide.
[tex]t^{2} = \frac{S_{1} }{1.1}[/tex]
[tex]t^{2} = \frac{23.13 }{1.1}[/tex]
[tex]t^{2} = 21.03\\t = \sqrt{21.03} \\t = 4.59 secs[/tex]
Hence, the time that elapses before the players collide is 4.59 secs
