     <span>a) 
Acceleration of stone = 10 

Integrate: 
So velocity = 10t 

Integrate again: 
So distance from starting point = 5t^2 

Distance from ground = 450-5t^2 

b) 
450 - 5t^2 = 0 


9.48 seconds 

c) velocity = 10t 

Put the time into this to give: 

94.8 m/s 

d. 

Velocity = 10t + 5 

Integrate again: 

5t^2 + 5t 


Solve 
5t^2 + 5t = 450 

Gives 9 seconds</span>

The velocity is 0t, here's how I got this answer

To find Velocity you must do dv/dt, so in this case it would look like this:

DV/DT = -9.8 which also equals V = -9.8t + C so in this case the Velocity would be 0 because -9.8 - (-9.8) = 0

2x+3y+2=0<br> 2x+y=-1<br> Want answer
ch4aika [34]

The value of the x and y are -1/4 and -1/2 if the system of equations are 2x + 3y = -2 and 2x + y = -1.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The two linear equations:

2x+3y+2=0

2x+y=-1

Solving by elimination method.

2x + 3y = -2

2x + y = -1

Subtract the equation first to second:

2y = -1

y = -1/2

Plug the above value in the equation second:

2x - 1/2 = -1

2x = -1 + 1/2

2x = -1/2

x = -1/4

Thus, the value of the x and y are -1/4 and -1/2 if the system of equations are 2x + 3y = -2 and 2x + y = -1.

Solve for m y-y=m(x-x)
spin [16.1K]

Answer:

m = y/x

Step-by-step explanation:

y-y = m(x-x)

simplify:

-2y = m(-2x)

simplify again

-2y = -2mx

divide to get rid of -2 and x

-2y = -2mx

----------------

-2x

y

-  = m

x
