The resale value of a textbook decreases by 25% with each previous owner. A new textbook is sold for $85. Which function represents the resale value of the textbook after x owners?
f(x) = 85(1 – 0.25)x
f(x) = 85(1 + 0.25)x
f(x) = 85(0.25)x
f(x) = (85 – 0.25)x
9514 1404 393
Answer:
(a) f(x) = 85(1 – 0.25)^x
Step-by-step explanation:
The growth rate is -25%, so the growth factor is 1-25% = 1 - 0.25.
Each increase in the number of previous owners causes the value to be multiplied by this growth factor, so the overall multiplier is (1 -0.25)^x
The value is the initial value times this multiplier:
f(x) = 85(1 -0.25)^x . . . . matches the first choice
The function that represents the situation is f(x) = 85 (1 - 0.25)ˣ
What is exponential decay?An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.
The exponential decay function:
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
Let's call the resale value of the textbook after x owners as f(x). We know that the resale value decreases by 25% with each previous owner. This means that after the first owner, the resale value will be 75% of the original value.
After the second owner, it will be 75% of 75% (or 56.25%) of the original value.
Similarly, after the third owner, it will be 75% of 75% of 75% (or 42.1875%) of the original value, and so on.
Using this information, we can write the function f(x) as:
f(x) = 85 (0.75)ˣ
f(x) = 85(1 - 0.25)ˣ
where 85 is the original value of the textbook (when x = 0), and (0.75)ˣ represents the percentage of the original value after x owners.
Therefore, the function that represents the resale value of the textbook after x owners is described as f(x) = 85 (0.75)ˣ.

Step-by-step explanation:
i know the coordinates are ( 0,-3 1/2 ) or ( 0, -3.5 ) for D
Answer:
(0,-2)
Step-by-step explanation:
Parallelograms have parallel lines and equal opposite lines.
You can count.
For Ex: A is 1 above and 5 to the left of B.
So D should be 1 above and 5 to the left of C.
C is at (5,-3)
Go up 1 and left 5 and you get (0,-2)

in (1,8) is y greater than x + 5
Answer:
True.
Step-by-step explanation:
Note the point values: (x , y) = (1 , 8) ∴ x = 1, y = 8
Plug in the corresponding numbers to the corresponding variables in the equation:
y > x + 5
(8) > (1) + 5
8 > 1 + 5
8 > 6
8 is greater than 6, ∴ y is greater than x + 5.

Two sailboats are traveling along the same path away from a dock, beginning from different locations at the same time. John’s boat beings 30 miles from the dock and is 50 miles from the dock after 5 hours. The distance of Roberta’s boat from the dock is represented by the function y = 5x + 25, where x represents time and y represents the distance from the dock.
Which boat was farther from the dock at the beginning, and which traveled more quickly?
A. John’s boat was farther from the dock at the beginning, but Roberta’s boat traveled more quickly.
B. Roberta’s boat was farther from the dock at the beginning, and it traveled more quickly.
C. John’s boat was farther from the dock at the beginning, and it traveled more quickly.

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Two sailboats are traveling along the same path away from a dock, beginning from different locations at the same time.
y = 5x+25
at starting x=0
y = 25 miles away from the dock
x = 5
y = 5×5+25
y = 50 miles
= (50 - 25)/5
= 5
Thus, the correct statement is John’s boat was farther from the dock at the beginning, and it traveled more quickly option (C) is correct.

How much force is needed to accelerate a 70 kg skier at 2 m/sec2?
Force = mass x acceleration
Force = 70 kg x 2 m/s^2
Force = 140 N
a force of 12N acts for 5 s on a mass of 2 kg. What is the change in momentum of a mass of 10kg under the same condition
Answer:
The change in momentum is: 60 N.s
Step-by-step explanation:
By Newton's second law:
F = ∆p / ∆t
Given that
∆t = 5sF = 12NUsing the formula to determine the change in momentum
F = ∆p / ∆t
∆p = F × ∆t
= 12 × 5
= 60 N.s
Therefore, the change in momentum is: 60 N.s

The correct option is;
3 units
Step-by-step explanation:
From the given figure, we have that segment DE is parallel to segment CB of triangle ABC
According to triangle proportionality theorem we have that segment DE which is parallel to segment CB of triangle ABC, divides the other two sides the triangle ABC proportionally
We have;
[tex]\overline {DC}[/tex]/[tex]\overline {AD}[/tex]= [tex]\overline {EB}[/tex]/[tex]\overline {AE}[/tex]
[tex]\overline {DC}[/tex]/9 = 4/12
[tex]\overline {DC}[/tex]= 9 × 4/12 = 3
[tex]\overline {DC}[/tex]= 3 units
The length of the segment DC = 3 units.
