I know that D is one of the answers. I'm not sure about the other ones.
Answers:
- DH is <u>correct</u> because a line is connecting the two points D and H as shown in the image, forming a <u>line segment</u>.
- ED is <u>correct</u> because a line is connecting the two points D and E, forming another <u>line segment</u>, as shown in the drawing.
- EH is <u>incorrect</u> because in the drawing shown, there is no line connecting the two points E and H, so there would be <u>no line segment</u> formed between these two points.
- CD is <u>correct</u> because there is another line connecting the two points C and D, forming another <u>line segment</u> in the drawing.
<u>Therefore, lines DH, ED, and CD are all line segments.</u>
Answer: 49.
It's 49 minutes
Step-by-step explanation:
I don't feel like explaining. It's 49 minutes.
Given that

, then

The slope of a tangent line in the polar coordinate is given by:

Thus, we have:

Part A:
For horizontal tangent lines, m = 0.
Thus, we have:

Therefore, the <span>values of θ on the polar curve r = θ, with 0 ≤ θ ≤ 2π, such that the tangent lines are horizontal are:
</span><span>θ = 0
</span>θ = <span>2.02875783811043
</span>
θ = <span>4.91318043943488
Part B:
For vertical tangent lines,

Thus, we have:

</span>Therefore, the <span>values of θ on the polar curve r = θ, with 0 ≤ θ ≤ 2π, such that the tangent lines are vertical are:
</span>θ = <span>4.91718592528713</span>
Answer:
The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.
Step-by-step explanation:
The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.
For example, if we consider a quadratic equation x² + 6x + 1 = 0, then two of its roots are - 3 + √8 and - 3 - √8 and they are conjugate of each other. (Answer)
