Divide 10 by 25, which would get you 4. Move the decimal over two to the left, because you wanted a percentage.
Jenny gave away 40% of the roses.
Answer:
The correct option is;
B. This equation is not considered to be a quadratic equation because it is not in the form a·x² + b·x + c = 0
Step-by-step explanation:
A. The given equation, x² - c = 0, can be presented in the form of the difference of two squares as follows;
(x + √c)·(x - √c) = 0
B. The equation x² - c = 0, is a quadratic equation because it is a polynomial equation of degree 2
C. The equation x² - c = 0 can always be factored as (x + √c)·(x - √c) = 0
D. Where c > 0, the equation x² - c = 0 can by the square root property as follows;
x² - c = 0
x² = c
x = √c
Let 
. The tangent plane to 
at (1, 2, -6) has equation
We have
Then the tangent plane has equation
Let 
, and 
. The tangent plane to 
at a point 
is
We have
so that this plane has equation
In order for this plane to be parallel to the previous plane, we need to have
so the point we're looking for is (2, 6, -36).
