Answer:
Ik thsi ik this ik this ok its D.
Step-by-step explanation:
The anser is D. bc it lists all possible outcomes
-1.25 or -1 1/4 that’s because the dot is in between a half and a whole number so one half divided by two is 1/4
PQ shows the height of the triangle from its base
As P is the highest point of the triangle
and Q lies on the base of the triangle
So PQ is the height of the triangle
And the height of any triangle is also known as the altitude of the triangle
So
PQ is nothing but the Altitude of this triangle
So option D is correct
Altitude
Complete Question
The complete question is shown on the first and second uploaded image
Answer:
The derived
Step-by-step explanation:
Step One : Consider the ellipse in equilibrium.
Looking at the ellipse in equilibrium i.e when the ellipse has settled down on the concave support (represented by a parabola ) as shown on the third uploaded image.
Step Two : Consider the ellipse equation.
Generally the equation of the ellipse is given as
Also the base on which it rest at equilibrium i.e the parabola is represented by
Substituting the value of y in the ellipse equation we have
Let
So the equation becomes
Rearranging, we get :
This equation above is a quadratic equation or a bi-quadratic equation in x as t =
Step Three : Relate the equation an the graph on the third uploaded image
We can see that from the graph , if A and B are the two values of x for which the points is made , then A + B = 0 (because they are symmetric in nature)
From Vieta's Roots(Vieta's formula is a formula that shows the relationship between the coefficients of a polynomial and the sum of its roots )
with A and B as roots
A+B =
But A + B = 0
So = 0
or we can say that
Rearranging we get
Answer:
Linear
Step-by-step explanation:
This can be written in slope intercept form (y=-5x+7) and there are no exponents.
