antoniya [11.8K]

Answer:

given mass =1500kg

intial velocity(u)=0 m/s

final velocity(v)=20m/s

time(s)=10 sec

accelerating force of the car engine=final velocity-intial velocity/time=20-0/10=20/10=2m/s^2

Write equations for the horizontal and vertical lines passing through the point (-6,1)
Oksanka [162]

Answer:

y = 1 and x = - 6

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c ( where c is the value of the y- coordinates the line passes through )

The line passes through (- 6, 1 ) with y- coordinate 1 , then

y = 1 ← equation of horizontal line

The equation of a vertical line parallel to the y- axis is

x = c ( where c is the value of the x- coordinates the line passes through )

The line passes through (- 6, 1 ) with x- coordinate - 6 , then

x = - 6  ← is equation of vertical line

Please help!!!!!!!!!!
blsea [12.9K]

Answer:

Step-by-step explanation:

a)  x  =  1.786 & -1.120

Explanation:

Turning points are points where the derivative equals zero. Solving the derivative for the values of X will give the answer to part a.

The derivative of this equation x^3 =x^2-6x[/t[tex]  is [tex]3x^2+2x-6.

Solving the equation 3x^2+2x-6=0 using the quadratic formula we get  1.786 & -1.120

b)  x = -3, x=0 and  x=2

Explanation:

The solution to this equation are the points where the graph intersects with the x axis. Looking at the graph we can see that these points are -3 , 0 and 2
