Question

Помогите пожалуйста,решить желательно фото с графиком Построить график уравнения скорости: U=20+5t , U=10t , U=100-5t

Answer 1

A) x(10)=-20+5*10=-20+50=30 c
б) x(-5)=-20+5*(-5)=-29-25=-45 м
в) 80=-20+5t
5t=100
t=20 c
график x(t)=-20+5t - прямая, проходящая через точки (5,-5),(2,10)

Answer 2

Graphing Equations of Velocity

To graph the equations of velocity U = 20 + 5t, U = 10t, and U = 100 - 5t, we can use a graphing tool to plot the velocity as a function of time.

Let's start by graphing each equation separately and then discuss the results.

Graphing U = 20 + 5t

The equation U = 20 + 5t represents a linear relationship between velocity and time. The velocity increases by 5 units for every unit increase in time, and the initial velocity is 20 units.

Now, let's plot this equation on a graph.

t | U
0 | 20
1 | 25
2 | 30
3 | 35
4 | 40

Graphing U = 10t

The equation U = 10t also represents a linear relationship between velocity and time. In this case, the velocity increases at a constant rate of 10 units per unit of time.

Let's plot this equation on the same graph.

t | U
0 | 0
1 | 10
2 | 20
3 | 30
4 | 40

Graphing U = 100 - 5t

The equation U = 100 - 5t represents a linear relationship as well, but in this case, the velocity decreases by 5 units for every unit increase in time. The initial velocity is 100 units.

Let's plot this equation on the same graph.

t | U
0 | 100
1 | 95
2 | 90
3 | 85
4 | 80

Combined Graph

Now, let's combine all three equations on the same graph to compare their relationships.


In the combined graph, we can observe the different linear relationships between velocity and time represented by the three equations. The graph will show how the velocities change over time according to each equation.

I hope this helps! If you have any further questions or need additional assistance, feel free to ask.
