There are 4 semi- trailer truck park a line at the stop. After the first truck, each in the line weights 2 tons more than the tr
Anna11 [10]

Let's say the first truck weighs x tons

Then, the weight of 2nd truck = x+2 tons

The weight of 3rd truck = (x + 2) + 2 = x+4 tons

The weight of 4th truck = (x + 4) + 2 = x+6 tons

Total weight of 4 trucks:

x + (x+2) + (x+4) + (x+6) = 32

 

which can be solved easily to give x = 5

Find the gradient and y intercept of 3x+4y=5
noname [10]

Answer:

gradient = - \frac{3}{4} , y- intercept = \frac{5}{4}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + 4y = 5 ( subtract 3x from both sides )

4y = - 3x + 5 ( divide terms by 4 )

y = - \frac{3}{4} x + \frac{5}{4} ← in slope- intercept form

with slope m = - \frac{3}{4} and y- intercept c = \frac{5}{4}

A mechanical system is governed by the following differential equation what is the homogeneous solution
Anika [276]

The ODE has characteristic equation

r^2+6r+9=(r+3)^2=0

with roots r=-3, and hence the characteristic solution

y_c=C_1e^{-3t}+C_2te^{-3t}

For the particular solution, assume an ansatz of y_p=ae^{-t}, with derivatives

\dfrac{\mathrm dy_p}{\mathrm dt}=-ae^{-t}

\dfrac{\mathrm d^2y_p}{\mathrm dt^2}=ae^{-t}

Substituting these into the ODE gives

ae^{-t}-6ae^{-t}+9ae^{-t}=4ae^{-t}=4e^{-t}\implies a=1

so that the particular solution is

\boxed{y(t)=C_1e^{-3t}+C_2te^{-3t}+e^{-t}}
