(x+2) is the answer.
you distribute (x+2)^2 then cancel out 'likes', which leaves you with (x+2)
Answer:the derivative of 1/x =-1/x^2
Step-by-step explanation:
1/x can also be written as x^-1
Therefore d/dx of x^-1
=-1*x^-1-1
=-1x^-2
Which can also be written as -1/x^2
Note: d/dx also means derivative of x
And d/dx (a/x^b) =(a*-b) /x^(b+1)
Where a and b represents a variable
Answer:
1
Step-by-step explanation:
Because it y is 0 then we can find the X intercepts. so there will be one X intercept.
Use the equation of midpoint (p is point)
Xp=Xa+Xb/2
4-2/2
2/2=1
Yp=Ya+Yb/2
9/2=4.5
So point (1,4.5)
Cos(arcsin(u)) = √(1 - u²)
_____
You want cos(α) where sin(α) = u.
You know that
cos(α)² + sin(α)² = 1
cos(α)² = 1 - sin(α)² = 1 - u²
cos(α) = √(1 - u²)
