The toy car will reach a height of approximately 3.25 meters above the ground.
To find the height above the ground that the 0.460 kg toy car gets when pushed with an initial velocity of 8.00 m/s up a frictionless incline, we can use the conservation of mechanical energy principle. Since there is no friction, the initial kinetic energy of the car will be converted into potential energy when it reaches its highest point.
Initial kinetic energy (KE) = 0.5 × mass × initial velocity²
KE = 0.5 × 0.460 kg × (8.00 m/s)²
KE = 14.72 J (Joules)
At the highest point, the car's kinetic energy will be converted into potential energy (PE):
PE = mass × gravity × height
14.72 J = 0.460 kg × 9.81 m/s² × height
Now, we can solve for the height:
height = 14.72 J / (0.460 kg × 9.81 m/s²)
height ≈ 3.25 m

Which equation correctly uses the value of x to represent the cosine of angle A? cos(53o) = StartFraction 4 Over x EndFraction cos(53o) = StartFraction y Over 5 EndFraction cos(53o) = StartFraction x Over 4 EndFraction cos(53o) = StartFraction 5 Over y EndFraction
Here is the full question:
Triangle ABC is a right-triangle and sin(53o) = StartFraction 4 Over x EndFraction. Solve for x & round to the nearest whole number.
Triangle A B C is shown. Angle A C B is a right angle and angle B A C is 53 degrees. The length of B C is 4 centimeters, the length of A C is y, and the length of hypotenuse A B is x.
Which equation correctly use the value of x to represents the cosine of angle A?
cos(53o) = StartFraction 4 Over x EndFraction cos(53o) = StartFraction y Over 5 EndFraction cos(53o) = StartFraction x Over 4 EndFraction cos(53o) = StartFraction 5 Over y EndFraction
Answer:
cos(53°) = StartFraction y Over 5 EndFraction
Step-by-step explanation:
From the information above:
The sketch of the triangle is drawn and attached in the diagram below.
To find x using the sine rule,
We know that:
\(Sin \theta = \dfrac{opposite}{hypothenuse}\)
∴
\(Sin (53^0) = \dfrac{4}{x}\)
Making x the subject of the formula:
\(x = \dfrac{4}{Sin \ 53^0}\)
\(x = \dfrac{4}{0.7986}\)
\(x \simeq 5\)
Now, the equation that correctly uses the value of x can be determined by finding the cosine of ∠ A.
Recall that:
\(Cos \theta = \dfrac{adjacent}{hypothenuse}\)
\(Cos \ 53^0 = \dfrac{y}{x}\)
where; x = 5
\(Cos \ 53^0 = \dfrac{y}{5}\)
Thus, the equation that correctly uses the value of x to represent the cosine of angle A is:
cos(53°) = StartFraction y Over 5 EndFraction

Answer: Its c
Step-by-step explanation:
I did it
The function that represents the total cost, in dollars, of a rafting trip at the resort is f(x) = 25x + 45
What is function?"It is a relation between input and output values.""In function, for each input there is exactly one output."For given question,
the fixed cost to rent a raft is $45
and the per person cost for each person in the raft is $25.
Here, the variable cost is the per person cost for each person in the raft as it depends on the number of people in the raft.
Let, x be the number people
The cost for 'x' people would be,
25x
So, the function that represents the total cost, of a rafting trip at the resort as a function of the number of people in the raft would be,
f(x) = 25x + 45
Therefore, the function that represents the total cost, in dollars, of a rafting trip at the resort is f(x) = 25x + 45

f(n) = -11 + 22(n = 1)
Complete the recursive formula of f(n).
f(1) =
f(n) = f(n - 1)+
Answer:
\(f(n)=f(n-1)+22\).
Step-by-step explanation:
Note: In the given function it should be (n-1) instead of (n=1).
Consider the given function is
\(f(n)=-11+22(n-1)\)
It is the explicit form of an A.P.
For \(n=1\),
\(f(1)=-11+22(1-1)=-11+0=-11\)
For \(n=2\),
\(f(2)=-11+22(2-1)=-11+22=11\)
Common difference is
\(d=a_2-a_1=11-(-11)=11+11=22\)
The recursive formula of an A.P. is
\(f(n)=f(n-1)+d\)
Substitute \(d=22\) in the above formula.
\(f(n)=f(n-1)+(22)\)
\(f(n)=f(n-1)+22\)
Therefore, required recursive formula is \(f(n)=f(n-1)+22\).

Mr. Ramirez purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under the age of 12.
Part A: Which system of equations represents the given scenario? Let a represent adults and c represent children.
A.10a + 15c = 20
a + c = 225
B.10a + 15c = 225
a + c = 20
C.15a + 10c = 225
a + c = 20
D.15a + 10c = 20
a + c = 225
Part B: What is the solution to the system of equations?
A.5 adults and 15 children
B.10 adults and 10 children
C.15 adults and 5 children
D.9 adults and 9 children
Answer:
Part A) C
Part B) A
Step-by-step explanation:
For part B I solved for a (adults) which then I got 5
I will attach an image of my work for part b
sorry for the poor quality picture
The system of equations that represents the given scenario is a + c = 20, 15a + 10c = 225 and the solution to the system of equations is a = 5 (adults) and c = 15 (children).
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let a represent the number of adult tickets and c represent the number of children's tickets.
The total number of tickets purchased is 20, so we have:
a + c = 20
The cost of an adult ticket is $15 and the cost of a children's ticket is $10. The total cost of the tickets is $225, so we have:
15a + 10c = 225
Therefore, the system of equations that represents the given scenario is:
a + c = 20
15a + 10c = 225
Now let us solve a and c values by using substitution method.
a=20-c
Now substitute in equation 15a + 10c = 225
15(20-c)+ 10c = 225
300 - 15c + 10c = 225
-5c = -75
c = 15
Substituting c = 15 into the first equation, we get:
a + 15 = 20
a = 5
Therefore, the system of equations that represents the given scenario is
a + c = 20, 15a + 10c = 225 and the solution to the system of equations is a = 5 (adults) and c = 15 (children).

two positive numbers have a ratio of 3:2 . the difference of their squares is 25. write an equation and solve to find the two numbers.
Step-by-step explanation:
x^2 -y^2 = 25
x/y = 3/2 or x = 3/2 y <=====sub into first equation
(3/2 y)^2 - y^2 = 25
9/4 y^2 - y^2 = 25
5/4 y^2 = 25
y^2 = 25 (4/5) = 20
y = sqrt (20) = 2 sqrt 5
then x = 3/2 y = 3 sqrt5
the average weight of a , b and c is 45 kg if the average of a and b is 40 kg that of b and c is 43 hen the weght of b is?
Therefore, the weight of B is 31 kg.
Let's solve the problem step by step.
1.Let's assign variables to the weights of the three individuals:
Weight of A = a
Weight of B = b
Weight of C = c
2.We are given that the average weight of A, B, and C is 45 kg:
(a + b + c) / 3 = 45
3.We are also given that the average of A and B is 40 kg:
(a + b) / 2 = 40
4.Additionally, we are given that the average of B and C is 43 kg:
(b + c) / 2 = 43
5.From equation 3, we can solve for a + b:
a + b = 2 * 40
a + b = 80
6.Substituting this value into equation 1:
(80 + c) / 3 = 45
7.Solving equation 6 for c:
80 + c = 3 * 45
80 + c = 135
c = 135 - 80
c = 55
8.Substituting the value of c into equation 4:
(b + 55) / 2 = 43
9.Solving equation 8 for b:
b + 55 = 2 * 43
b + 55 = 86
b = 86 - 55
b = 31
Therefore, the weight of B is 31 kg.

6x = 120°
x = 120/6 = 20°
