Answer:
Choice D is correct
Step-by-step explanation:
The first step is to write the polar equation of the conic section in standard form by dividing both the numerator and the denominator by 2;
The eccentricity of this conic section is thus 1, the coefficient of cos θ. Thus, this conic section is a parabola since its eccentricity is 1.
The value of the directrix is determined as;
d = k/e = 3/1 = 3
The denominator of the polar equation of this conic section contains (-cos θ) which implies that this parabola opens towards the right and thus the equation of its directrix is;
x = -3
Thus, the polar equation represents a parabola that opens towards the right with a directrix located at x = -3. Choice D fits this criteria
Answer:
The Exponential function is
And the polynomial function is
And, we have to find the value of x for which, exponential function exceeds the polynomial function which can be written as
1. When , x= -1
LHS
RHS
2. When , x=0
L HS
RHS
3. When ,x= 0.5
L HS
RHS
4. When , x=2
LHS
RHS
The Minimum value for which exponential function exceeds the polynomial function is , x= 0.5
But,there is other value for which exponential function exceeds the polynomial function is , x=2.
It's been a while since I have done these kind of questions, but I would say a 180 transformation would be my best answer. Hope this helps a bit!
Automatically we know that he is wrong because even if we round it to make it a friendly number (lets say 1) it will still not equal 3 1/2
he has them for 3 1/2 days
even 1+1+1= 3 it still isnt enough and you arent even supposed to round
That is why he is wrong :) hope this helped
