(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.
(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.
What is velocity?Velocity is the rate of change of displacement with time. The velocity of the cars depends on displacement and time of motion.
First velocity of the car at the 0.25 meter markThe first velocity is calculated as follows;
v1 = 0.25 m / t1
let t₁ = 2 s
v₁ = 0.25/2
v₁ = 0.125 m/s
Second velocity of the car at the 0.5 meter markv2 = 0.25 m / (t2 – t1)
let t₂ = 3 s
v₂ = 0.25(3 - 2)
v₂ = 0.25 m/s
The complete question is below:

Bob's monthly net income is $3,000. Bob pays $950 for rent, $250 for all
utilities, and $1,850 in other fixed and variable expenses. What is Bob's
cash flow?
A.Negative cash flow, $50
B.Negative cash flow, $3,050
C.ositive cash flow, $3,050
D.Positive cash flow, $50
Answer:
A: Negative cash flow, $50
Step-by-step explanation:
Bob makes $3000 a month.
Every month he has to pay $950:
3000 - 950 = 2050
Pay an additional $250:
2050 - 250 = 1800
And another additional $1850:
1800 - 1850 = -50
Therefore, he has a negative cash flow of $50 a month.

Lucy has 68 books.
This number of books is 70% more than the number of books she had last year.
How many books did Lucy have last year?
Answer:
Lucy had 40 books last year.
Step-by-step explanation:
assuming 100% is the percent;
100% + 70%
100 : x
170 : 68
cross multiply = 170x = 100 x 68
-------- ————-
170 170
cancel 170/170
therefore x = 100 x 68 divided by 170
result is 40
The number of books that Lucy has last year will be 40 books.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Lucy has 68 books. This number of books is 70% more than the number of books she had last year.
Let 'n' be the number of books. Then the equation is given as,
1.7 n = 68
n = 68 / 1.70
n = 40
The number of books that Lucy has last year will be 40 books.

Which statements are true regarding the sides and angles of the triangle? Select three options. Line segment X Y is the longest side. Angle X is the largest angle. Angle Z is greater than angle Y. Line segment X Z is opposite the largest angle. Line segment X Z is the shortest side.
Answer:
B. Angle X is the largest angle.
C. Angle Z is greater than angle Y.
E. Line segment X Z is the shortest side.
Step-by-step explanation:
YZ = 2n, XZ = n - 2, XY = n + 4 and n ≥ 5.
YZ - XZ = 2n - (n - 2) = n + 2. but n ≥ 5, hence YZ - XZ = n + 2 ≥ 7.
YZ > XZ
YZ - XY = 2n - (n + 4) = n - 4. but n ≥ 5, hence YZ - XY = n - 4 ≥ 1
YZ > XY
XY - XZ = n + 4 - (n - 2) = 6: XY > XZ
Therefore:
YZ > XY > XZ
The angles are proportional to their opposite sides, hence:
∠X > ∠Z > ∠Y
A. Line segment XY is the longest side.
This is wrong because YZ is the longest side.
B. Angle X is the largest angle.
This is correct. ∠X is the largest angle because it is opposite to the longest side (YZ)
C. Angle Z is greater than angle Y.
This is correct. ∠Z is opposite to the side XY while ∠Y is opposite to the side XZ
D. Line segment XZ is opposite the largest angle.
This is wrong. ∠X is the largest angle which is opposite to the longest side (YZ)
E. Line segment X Z is the shortest side.
This is correct

Answer:
An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x
