Answer:
The equation is an differential equation of second order.
The dependent variable is x, while t is the independent variable.
Step-by-step explanation:
The order of the equation depends on the greatest grade of the derivative, in this case it's the second derivative (x'')
Since x is a function of t, we would have that t is the independent variable while x is the dependent variable.
D. 35, since that would be the longest amount. of time walking away from her house, she should be the farthest amount of feet away from her house
Answer:
2
Step-by-step explanation:
The discriminant is the quantity under the radical in the quadratic formula ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[tex]
When that quantity is positive, the square root is real, and the formula gives two real values for x.
Answer:
Step-by-step explanation:
(5 + (-1))/2 = 4/2 = 2
(8 + (-4))/2= 4/2 = 2
(2, 2) is the Midpoint
We know that cot = cos/sin
then cot^3 = cos^3 / sin ^3
we also know that csc = 1/sin
then 1/csc = sin
cot^3t/csct
=(cos^3t / sin^3t) * sint
=cos^3t / sin^2t
1+cot^2 = csc^2
csc^2 -1 = cot^2
cost(csc^2t-1)
=cost(cot^2t)
cost( cos^2t/sin^2t)
=cos^3t/sin^2t
It implies that both sides are equal
