The acceleration of the car three seconds before it comes to a stop is 0m/s²
Given the velocity function expressed as v(t) = -3t^2 + 18t + 9
Acceleration is the change in velocity of a body with respect to time.
a(t) = dv/dt
Differentiating the velocity with respect to time will give;
dv/dt = -6t + 18
a = -6t + 18
a = -3(6) + 18
a = -18 + 18
a = 0m/s²
Hence the acceleration of the car three seconds before it comes to a stop is 0m/s²

Carl is boarding a plane. He has 222 checked bags of equal weight and a backpack that weighs 4 \text{ kg}4 kg4, start text, space, k, g, end text. The total weight of Carl's baggage is 35 \text{ kg}35 kg35, start text, space, k, g, end text.
Write an equation to determine the weight, www, of each of Carl's checked bags.Find the weight of each of his checked bags.
Answer:
[tex]w=15.5[/tex]
[tex]w=\frac{31}{2}[/tex]
Equation:
[tex]2w+4=35[/tex]
Step-by-step explanation:
[tex]2w+4=35\\2w=31\\w=15.5[/tex]
Hidden Steps:
1) Subtract 4 on each side of the equation:
[tex]2w+4-4=21\\35-4=31[/tex]
2) Divide each side of the equation by 2:
[tex]2w[/tex] ÷ [tex]2=w[/tex]
[tex]31[/tex] ÷ [tex]2=15.5-or-\frac{31}{2}[/tex]
Answer:
Equation: 2w + 4 = 35
Weight: 15.5
Step-by-step explanation:
Let w be the weight of each checked bag.
The weight of Carl's 2 checked bags is 2w kg. The weight of his backpack is 4kg. The total weight of his baggage is 2w + 4 kg.
Since his total baggage weighs 35 kg, let us set this to 35:
2w + 4 = 35
Now you solve:
1. 2w + 4 = 35
2. 2w = 35-4
3. 2w = 31
4. w = 31/2
5. w = 15.5
Therefore, the equation is 2w + 4 = 35 and the solution to " w " is 15.5 kg.

What is quadratic equation?A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
Given:
f(x) = ax² + bx + c
The first condition for an equation to be a quadratic equation is the coefficient of x² is a non-zero term(a ≠ 0).
For writing a quadratic equation in standard form, the x² term is written first, followed by the x term, and finally, the constant term is written.
Hence, The constants a, b, and c must be real numbers with a not ever equal to zero.

Step-by-step explanation:
Triangle PQR and triangle STR are congruent and that makes |PR| and |SR| equal in measure:
2x + 6 = 4x export like terms to same side
6 = 4x - 2x subtract
6 = 2x divide both sides by 2

The youth group is going on a trip to the state fair. The trip costs $62. Included in that price is $14 for a concert ticket and the cost of 2 passes, one for the rides and one for the game booths. Each of the passes costs the same price. Write an equation representing the cost of the trip, and determine the price of one pass. Solve your equation by showing your work and steps.
Answer:
11+2x= 52 , $20.50 equal one pass
Step-by-step explanation:52 is the total and $11 is included in that total. So you have part of your equation : 11 + something = 52. In order to find that " something " you have to set up a variable : 2x , 2 because that is the amount of passes bought and X because you don't know the cost of the passes yet. You now have your equation : 11+2x=52. Next you isolate the "2x" by subtracting eleven from itself and what you do to one side of the equation you have to do to the other, so you subtract 11 from 52 and are left with 41 . You then have the simplified equation : 2x=41 . Now you're going to isolate the variable by dividing 2x by 2 and doing the same to 41. You're then left with X= 20.50 , the cost of one ticket
