It seems like σ(t) is the positive function of the particle. Compute its acceleration by differentiating this function twice.
σ(t) = {t ², sin(t ), cos(t )}
σ'(t) = {2t, cos(t ), -sin(t )}
σ''(t) = {2, -sin(t ), -cos(t )}
When t = 0, the acceleration on the particle is
σ'' (0) = {2, -sin(0), -cos(0)} = {2, 0, -1}
Then the force acting on the particle at time t = 0 is
F = {2m, 0, -m}
by Newton's second law.

A glass is
1
6
full. Then 95cm3 of orange juice is poured in.
The glass is now
4
5
full. What is the total volume of the glass?
Answer:
let x = the amount of orange juice in a full glass.
the glass is 1/6 full = 1/6 * x
add 95 cubic centimeters and the glass becomes 4/5 full.
equation for that is:
1/6 * x + 95 = 4/5 * x
subtract 1/6 * x from both sides of this equation to get:
95 = 4/5 * x - 1/6 * x
multiply 4/5 * 6/6 and multiply 1/6 * 5/5 and the equation becomes:
95 = 24/30 * x - 5/30 * x
combine like terms to get 95 = 19/30 * x
multiply both sides of the equation by 30/19 to get:
30/19 * 95 = 30/19 * 19/30 * x
simplify to get:
30/19 * 95 = x
solve for x to get x = 150.
the volume of the glass is 150 cubic centimeters.
1/6 * 150 = 25
4/5 * 150 = 120
the difference between 4/5 full and 1/6 full is 95 cubic centimeters.
solution is that the volume of the glass is 150 cubic centimeters.

Three weeks ago, an art supply store started selling a paint kit for 75% of the original price. Now the kit is 15% off of the sale price. The expression 0.75x - 0.15(0.75x) represents the current price of the paint kit where x is the kit’s original price (in dollars). Find the current price of the kit if it originally cost $48.
Answer:
$30.60
Step-by-step explanation:
0.75X-0.15(0.75X)
0.75(48)-0.15(0.75(48))
0.75(48)-0.15(36)

(d) a and b were born on the same day;
A. symmetric
B. reflexive
C. transitive
D. antisymmetric
E. irreflexive
Answer:
a) Options A, B & D.
b) Options C & D.
c) Options C, D & E
d) Options A, B & C
Step-by-step explanation:
a) Options A, B & D.
- It's irreflexive because b is not older than a.
- It's transitive because if a is older than b as we are told and b is older than c, then we can say that a is older than c.
- It's antisymmetric because if a is older than b, then we can say that b is not older than a.
b) Options C & D.
- It's symmetric because if a & b have a common grandparent, then we can say that b and a have a common grandparent.
- It's reflexive because a and b have common grandparents and thus implies all of a's grandparents.
c) Options C, D & E are correct.
It could be Transitive, symmetric or antisymmetric.
d) Options A, B & C are correct.

Cases of congruency
SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and including angle in the 2nd Δ ASA ⇒ 2 angles and the side whose joining them in the 1st Δ ≅ 2 angles and the side whose joining them in the 2nd Δ AAS ⇒ 2 angles and one side in the 1st Δ ≅ 2 angles and one side in the 2nd Δ HL ⇒ hypotenuse and leg of the 1st right Δ ≅ hypotenuse and leg of the 2nd right ΔLet us solve the question using the 4th rule above
∵ YZ = YO + OZ
∵ NO = NZ + ZO
∵ OZ = ZO ⇒ from the figure
∵ YO ≅ NZ ⇒ given
∴ YZ ≅ NO
In Δs MNO and XYZ
∵ ∠M ≅ ∠X ⇒ given
∵ ∠N ≅ ∠Y ⇒ given
∵ NO ≅ YZ ⇒ proved
→ By using the AAS postulate of congruency.
∴ Δ MNO ≅ ΔXYZ

Latoya finished her English assignment in 1/2 hours. Then she completed her history assignment in 2/3 hours. How much more time did Latoya spend on her history assignment?
1/6 more hours. Because 1/2 and 2/3 are equal to 3/6 and 4/6. Then you subtract and get 1/6
The time Latoya spend on completing her history assignment is given by the equation A = 1/6 hours
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The time for Latoya to complete her English assignment = 1/2 hours
The time for Latoya to complete her History assignment = 2/3 hours
So , the difference in time = extra time for Latoya to complete history assignment
Substituting the values in the equation , we get
The difference in time A = ( 2/3 ) - ( 1/2 )
The difference in time A = ( 4 - 3 ) / 6
The difference in time A = 1/6 hours
Hence , the equation is A = 1/6 hours

The cost of a pound of nails increased from $2.17 to $2.52. What is the percent of increase to the nearest whole-number percent?
Answer:
16% is the percent of increase to the nearest whole-number percent.
Step-by-step explanation:
As the cost of a pound of nails increased from $2.17 to $2.52.
$2.52 - $2.17 = $0.35so dividing the 0.35 by 2.17 would give us the percetange of increase
0.35/2.17 = 0.16 which is 16%.Therefore, 16% is the percent of increase to the nearest whole-number percent.
