Answer:
( x+2)^2 + (y+5)^2 = 1
Step-by-step explanation:
The equation of a circle can be written in the form
( x-h)^2 + (y-k)^2 = r^2
where ( h,k) is the center and r is the radius
( x- -2)^2 + (y- -5)^2 = 1^2
( x+2)^2 + (y+5)^2 = 1
The volume of the square pyramid is 600cm^3
General form of vertex of a parabola is
y = a(x - b)^2 + c where vertex = (b , c)
for this equation the vertex is at (-1,0).
the axis of symmetry is x = -1
Answer:
There are 2
Step-by-step explanation:
Answer:



Step-by-step explanation:
Given



(0, 1, 0)
The vector equation is given as:

Substitute values for x, y and z

Differentiate:

The parametric value that corresponds to (0, 1, 0) is:

Substitute 0 for t in r'(t)




The tangent line passes through (0, 1, 0) and the tangent line is parallel to r'(0)
It should be noted that:
The equation of a line through position vector a and parallel to vector v is given as:

Such that:
and 
The equation becomes:




By comparison:
and 
The parametric equations for the tangent line are:
