What is the definition of a velocity simple?
The direction of the movement of the body or the object is defined by its velocity. In its basic form, speed is a scalar quantity.
In essence, velocity is a vector quantity. It measures how quickly a distance changes. It is the displacement change rate.
vo = 48 v(t) = integral of a(t) plus vo, the initial velocity
a(t) = -2
v(t) = -2t + 48 = 0 when t= 21 seconds, the time to stop
s(t) = -t^2 +48t
s(21) = -(21)^2 + 48(21) = 1008-441 = 567 feet

Is this proportional or not proportional?
A machine in a factory can assemble 234 units in 3 hours. Matt wants to write an equation to represent this situation. He says that the independent variable is the number of units assembled; the dependent variable is the number of hours, and the constant of proportionality is 78. What mistake did matt make in finding the parts of the equation that represents this relationship?.
Matt should take dependent variable is the number of units assembled; the independent variable is the number of hours to make it correct.
Explain variables.A variable is any qualities, number, or amount that can be estimated or counted. A variable may likewise be known as an information thing. Age, sex, business pay and costs, nation of birth, capital use, class grades, eye tone and vehicle type are instances of factors.
According o question:Considering that a machine in a plant can collect 234 units in 3 hours. Free factor is the no of units gathered and subordinate variable is the time taken.
Let y be number of hours and x be number of units assembled;
So, we can write
y = mx
Slope = y/x = 3/234 = 1/78
constant of proportionality is 78 is inverse, so To make correct we have to take dependent variable is the number of units assembled; the independent variable is the number of hours.

f’’(x)=cos(x), f’(pi)=2, f(pi)=-1
f(x)=?
PLS URGENT
The required function f(x) is represented by -1 + F(x + sin(x)).
To find the function f(x), you can use the formula for integration by substitution:
f(x) = F(g(x)) + C
where F is an antiderivative of f, g is a function such that g'(x) = f(x), and C is a constant.
In this case, we can take g(x) = x + sin(x). Then g'(x) = cos(x), so f(x) = F(g(x)) + C = F(x + sin(x)) + C.
We are given that f'(π) = 2 and f(π) = -1, so we can use these values to find the constants C and F.
First, we can find F by taking the derivative of F(x + sin(x)). This gives us:
F'(x + sin(x)) = f(x) = cos(x)
Substituting x = π and using the fact that F'(x + sin(x)) = f'(π) = 2, we get:
F'(π + sin(π)) = 2
Since sin(π) = 0, this simplifies to:
F'(π) = 2
Then, using the fact that F(x + sin(x)) = f(π) = -1 when x = π, we can find the value of F(π):
F(π) = -1
Now that we have found the values of F and F', we can use these to find the value of C.
Since F(x + sin(x)) = F(x) + F'(x) sin(x), we can substitute x = π to get:
F(π + sin(π)) = F(π) + F'(π) * sin(π)
Substituting the values we found above, this becomes:
F(π + 0) = -1 + 2 x 0
Which simplifies to:
F(π) = -1
Since F(π) = -1, we can conclude that C = -1.
Therefore, the function f(x) is given by:
f(x) = F(x + sin(x)) + C = F(x + sin(x)) - 1
= -1 + F(x + sin(x))

The enrollment for a school in 2010 was 1510 students. In 2020, the enrollment was 860 students. Find and interpret the rate of change in enrollment from 2010 to 2020.
Answer:
Step-by-step explanation:
The rate of change is the slope of the line formed by connecting the two data points:
1. (2010,1510). and [enrollment for a school in 2010 was 1510 students]
2. (2020, 860) [In 2020, the enrollment was 860 students]
Slope is the Rise/Run of the line. Lets go from the first point to the second.
The Rise: (1510 - 860) = 650
The Run: (2020-2010) = 10
The slope, or rate of change, is = 65

Despite what he may have told you, Mr. Robeson is actually quite bad at
making free throws in basketball. On average he makes 35% of the free
throws he takes and he doesn't learn from previous shots. What is the
probability that the first time he makes a free throw is on the 5th shot he
attempts?
Answer:
0.009754
Step-by-step explanation:
(.65)^4 x (0.35)
By saying that he makes a free throw on the fifth show, he did not make the first four, therefore 4 of the times he shot, he did not get it in.
If he makes the shot 35% of the time, he doesn't make it 65% of the time: (1-0.35=.65)
On the last shot he made it, which he makes 35% of the time therefore:
You want to multiply : 0.35 (which is = 35%) by itself four times and then multiply that by 0.65 (since the last shot was made)
0.35 x 0.35 x 0.35 x 0.35 x 0.65 = 0.009754 or 0.9754%
There is a 0.9754% chance he makes it BUT a 0.009754 probability

please help: in the figure, ∆LMN ≅ ∆RST. find the values of x and y
Answer:
X=8, y=19
Step-by-step explanation:
These two triangles are congruent. This means that angle STR = angle MNL, so angle STR = 63°. We know the angles in a triangle must sum to 180°, so we can figure out 3x from this, given that we know the other two angles. 63 + 93 = 156, so 3x = 180-156=24. This gives us that x = 8. Now we can solve for x, because we know that SR = ML, so 3x + y = 43. We know x = 8, so we get that 24 + y = 43, or y = 19.

The midpoint of \overline{\text{AB}} AB is M(4, 0)M(4,0). If the coordinates of AA are (3, -1)(3,−1), what are the coordinates of BB?
Answer:
The midpoint of a line segment is the point that is exactly halfway between the two endpoints of the line segment. If the coordinates of one endpoint are (x1, y1) and the coordinates of the other endpoint are (x2, y2), then the coordinates of the midpoint are given by:
M = ((x1 + x2)/2, (y1 + y2)/2)
In this case, the coordinates of the midpoint are (4, 0), and the coordinates of AA are (3, -1). Therefore, the coordinates of BB must be (5, 1).
You can confirm this by calculating the midpoint using the coordinates of AA and BB:
M = ((3 + 5)/2, (-1 + 1)/2)
= (4, 0)
This shows that the point (5, 1) is indeed the other endpoint of the line segment, and the coordinates of BB are (5, 1).

Plant A i 5 centimeter tall and growing at a rate of 2. 5 centimeter per month. Plant B i 4 centimeter and growing at a rate of 4. 5 centimeter per month. When will Plant B exceed the height of Plant A. Write an inequality that repreent the ituation
In linear equation, plant b height will exceed the height of plant a after 16 days.
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
Plant a: 5 cm tall and rate of change = 2.5 cm per month
Plant b: 4 cm tall and rate of change = 4.5 cm per month.
Now we have to form the linear equations.
Plant a:
y = 2.5x + 5, where y is the total height and "x" be the number of months.
Plant b:
y = 4.5x + 4 , where y is the total height and "x" be the number of months.
Now we have to when the height of the plant a and plant b are the same.
To do that, we have to equivate both the equations and find x.
2.5x + 5 =4. 5x + 4
Isolate the variables terms and constants.
4.5x - 2.5x = 5 - 4
2x = 1
Dividing both sides by 2, we get
x = 1 ÷ 2
x = 0.5 months.
So after 15 days, the height of the plant a and plant b are the same.
Therefore, plant b height will exceed the height of plant a after 16 days.
