A particle moves along a line so that its position at any time is t greater than or equal to 0 is given by s(t)=-t^2+t+2 where s is measured in meters and t is measured in seconds. A) what is the initial position of the particle? B) find the velocity of the particle at any time t. C) find the acceleration of the particle at any time t. D) find the speed of the particle at the moment when s(t)=0.
Answers
Answer:
A) The initial position of the particle is 2 meters.
B) The velocity of the particle at any time t is represented by [tex]v(t) =-2\cdot t +1[/tex].
C) The acceleration of the particle at any time t is represented by [tex]a(t) = -2[/tex].
D) The velocity of the particle at the moment when [tex]s(t) = 0\,m[/tex] is -2 meters per second.
Step-by-step explanation:
A) From statement we know that [tex]s(t) = -t^{2}+t+2[/tex], where [tex]t[/tex] is the time, measured in seconds, and [tex]s(t)[/tex] is the distance, measured in meters. The initial position of the particle is calculated by evaluating the function presented above at [tex]t=0\,s[/tex]. That is:
[tex]s(0) = -(0)^{2}+(0)+2[/tex]
[tex]s(0) = 2\,m[/tex]
The initial position of the particle is 2 meters.
B) According to the Theory on Kinematics, we see that velocity is the rate of change of position in time. In other words, we need to derive the equation once:
[tex]v(t) =-2\cdot t +1[/tex] (1)
Where [tex]v[/tex] is the velocity, measured in meters per second.
The velocity of the particle at any time t is represented by [tex]v(t) =-2\cdot t +1[/tex].
C) And the acceleration is the rate of change of velocity in time. In other words, we need to derive the equation above:
[tex]a(t) = -2[/tex] (2)
The acceleration of the particle at any time t is represented by [tex]a(t) = -2[/tex].
D) At first we solve the function position for [tex]s = 0[/tex], that is:
[tex]-t^{2}+t+2=0[/tex] (3)
[tex](t-2)\cdot (t+1)=0[/tex]
The only reasonable root of the polynomial is [tex]t = 2\,s[/tex].
And now we evaluated the velocity function at given result:
[tex]v(2) = -2\cdot (2) +2[/tex]
[tex]v(2) = -2\,\frac{m}{s}[/tex]
The velocity of the particle at the moment when [tex]s(t) = 0\,m[/tex] is -2 meters per second.
The perimeter of a rectangle is 46.The length is 7 less than 4 times the width. What are the dimensions of the garden?
Answers
answer= 102
Step-by-step explanation:
Given,
Perimeter=46
Let, breadth=X
Then, length = 4X-7
Now,
Perimeter= 2(l+b)
46 = 2(4X-7+X)
46 = 2(5X-7)
(46)÷2 = 5X-7
23+7 = 5X
30 = 5X
30÷5 = X
:-X = 6
Also,
length = 4×6-7 = 17
breadth = 6
Then,
Dimensions = l×b
= 17×6
= 102
Answer:
the width = 6 unitsthe length = 17 unitsStep-by-step explanation:
Let 'w' be the width
The length is 7 less than 4 times the width.so the length = 4w - 7
The formula of the Perimeter is
Perimeter = 2(length + width)
46 = 2(4w - 7+ w)
46 = 2(5w- 7)
46 = 10w-14
46+14 = 10w
60 = 10w
w = 6
Hence,
the width = 6 unitsthe length = 4w - 7 = 4(6)-7= 24-7=17 unitsNeed help asap with geometry!

Last year Beth's annual salary was $38,350. This year she received a promotion and now earns $46,462 annually. She is paid biweekly.
a.) What was her biweekly salary last year?
b.) What is Beth’s biweekly salary this year?
c.) On a biweekly basis, how much more does Beth earn as a result of her promotion?
Answers
Answer:
Quite simple. There are 52 weeks in a year. She gets paid 26 times, every other week.
38,350 / 26 = her salary from last year per check.
46,462 / 26 = her new salary per check
(46,462 - 38,350) / 26 = the difference per week
a. last year Beth's biweekly salary was 1597.91 dollars.
b. This year Beth's biweekly salary is 1935.91 dollars.
c. On a biweekly basis she earns 338 dollars more now as a result of her promotion.
How to convert months into bi-weeks ?One months contains 2 bi-weeks therefore to convert months into bi-weeks we have to multiply the given months by 2.
According to the given question
Last year Beth's annual salary was 38350 dollars.
∴ Her monthly salary was (38350/12) dollars.
= 3195.83 dollars.
She is being paid biweekly meaning twice a month in every two weeks interval.
∴ Her biweekly amount is
=(3195.83/2) dollars
= 1597.91 dollars. (a).
So, her salary last year was 1597.91 dollars biweekly.
This year she received a promotion and now earns 46462 dollars per year.
∴ Her biweekly salary is
= (46462/2×12) dollars. ( as there is 2 bi-weeks in every months)
= 1935.91 dollars. (b).
As a result of her promotion she earns (1935.91 - 1597.91) dollars more as a result of her promotion.
= 338 dollars.

Use inductive reasoning to predict the next number in the pattern: 832, 208, 52...
A.) 13
B.) -228
C.) -26
D.) 26
Answers
Answer:
A) 13 i think
Step-by-step explanation:
832 , 208 , 52
The difference between 832 and 208 is 624 and then the difference between 208 and 52 is 156. If we check the relation between 624 and 156 which is 624/4 = 156 so then if we divide 156 by 4 we get 39 and then subtract 39 from 52 we get 13.

on weekends a movie ticket costs $10.50. form an inequality and solve it to find the maximum umber of tickets kate can buy with $205
Answers
Answer:
kate can buy 20 tickets
Step-by-step explanation:
hope this helps
i am not sure about the answer
10.50x ≤ 205
The maximum number of tickets, x, would be 19.
Step-by-step explanation:
Given,
The cost of one ticket = $ 10.50,
The cost of x tickets = 10.50x dollars,
Since, the total cost can not exceed $ 205,
⇒ 10.50x ≤ 205
∵ 10.50 > 0 thus, when we multiply both sides by 1/10.50 the inequality sign will not change,
⇒ x ≤ ≈ 19.52
Hence, the maximum number of tickets would be 19.

1.) Add 7 to both sides:[tex]-7+7=[/tex] Cancels Out[tex]11+7=18[/tex]- We have to get rid of both numbers on each side, so to do so, we do the opposite of what we see: Since we have a negative 7, we add 7 on each side.

[tex]-3x[/tex] ≤ [tex]18[/tex]2.) Divide both sides by -3:[tex]-3[/tex] ÷ [tex]-3=[/tex] Cancels Out[tex]18[/tex] ÷ [tex]-3=-6[/tex]- We have to get rid of numbers on each side, so do to so, we do the opposite of what we see. Since we have a negative 3 being multiplied, we divide by -3 instead.

8. Center
As the location of the center of the circle is (3, 3).
Therefore, the coordinates of the center are (3, 3)9. Endpoints of a diameter
As we know that the diameter is the magnitude (often called the length) of the line through the center.
Please note that the diameter touches two points on the edge of the circle. Diameter is often called the longest possible chord.From the diagram, it is clear that:
The points of the diameter are (6, 3) and (0, 3).Also, observe the length of a diameter is 6 units.
10. A point of Tangency
We know that at the point of Tangency, the tangent to a circle will always be perpendicular to the radius.
From the diagram, it is clear that:
(6, 3) is the point of tangency. Here the tangent is perpendicular to the radius.11. Endpoints of a chord that is not a diameter
A chord is basically a line that touches two points.
From the diagram, it is clear that:
The coordinates of the chord other than the diameter are (3, 0) and (0, 3).12. Endpoints of a radius
We know that a radius is basically a straight line from the center of a circle to the circumference of a circle.
The length of a radius r = diamter length/2
From the diagram, it is clear that:
The coordinates of the endpoints of the radius are (3, 3) and (6, 3)Round 621.97 to tens place. What is It?
