<span>1.) Factor the denominator into 2 expressions leaves you with:
(x-2)/(x+5)(x-2)
x-2 cancels out, you are left with 1/(x+5), excluding x=2

Step-by-step explanation:
From the question we are told that

Now integrating both sides

Now taking the exponent of both sides

=> 
Let 
So

Now from the question we are told that

Hence

=> 
So

From the question we are told that

substituting for y

=> 
Now integrating both sides

Now taking the exponent of both sides

=> 
Let 
=> 
Now from the question we are told that

So

=> 
divide both side by 
=> 
So

=> 
=> ![x(t) = x_o e^{\frac{\alpha y_o }{\beta }[e^{-\beta t} - 1] }](https://tex.z-dn.net/?f=x%28t%29%20%3D%20%20x_o%20e%5E%7B%5Cfrac%7B%5Calpha%20y_o%20%7D%7B%5Cbeta%20%7D%5Be%5E%7B-%5Cbeta%20t%7D%20-%201%5D%20%7D)
Generally as t tends to infinity ,
tends to zero
so

Step-by-step explanation:
1. x^2 + 10x + 25
2. x^2 - 25

Answer:

Step-by-step explanation:
The given matrix addition is

We need to find the elements of matrix B.
Let 
Substitute the value of matrix.

After addition of two matrix we get

On equating both sides.






Therefore, the elements of matrix B are
.
Answer:
π
Step-by-step explanation:
Formula for the circumference of a circle
2r(π)
Area of a circle
πr²
2r(π)=x
x/2(π)=r
π(x/2(π))²=Area
π(x²/4(π)²)=Area
(x²/4(π))=Area
(15π)²÷4π=Area
π
