Topic : Geometry Can someone tell me what Conic sections is in 4-8 sentences ?

1 answer:

3 0

Conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse. The circle is a special case of the ellipse, previously called the fourth type. Planes that pass through the vertex of the cone will intersect the cone in a point, a line or a pair of intersecting lines, called degenerate conics.

Do you know The answer for If R is the midpoint of QS, QR =8x - 51 and RS = 3x - 6 find QS

7nadin3 [17]

Answer:

Step-by-step explanation:

R is midpoint

|<---------------- QS -------------------->|

Q---------------------R--------------------S

8x - 51 3x - 6

find: QS

QR = RS

8x - 51 = 3x - 6

8x - 3x = 51 - 6

5x = 45

x = 45/5

x = 9

QS = QR + RS

QS = (8x - 51) + (3x - 6)

plugin the value of x=9 into the equation above:

QS = (8(9) - 51) + (3(9) - 6)

QS = 72 - 51 + 27 - 6

QS = 42

Factor completely 81x^8-1

marysya [2.9K]

The complete factorized form for the given expression is $\left(9 x^{4}+1\right)\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)$

<u>Step-by-step explanation:</u>

Step 1: Given expression:

$81 x^{8}-1$

Step 2: Trying to factor as a Difference of Squares

Factoring $81 x^{8}-1$

As we know the theory that the difference of two perfect squares, $A^{2}-B^{2}$ can be factored into (A+B) (A-B)

from this, when analysing, 81 is the square of 9, $x^{8}$ is the square of $x^{4}$ . Hence, we can write the given expression as,

$\left(9 x^{4}\right)^{2}-1^{2}$

By using the theory, we get

$\left(9 x^{4}+1\right)\left(9 x^{4}-1\right)$

Again, we can further factorise the term $\left(9 x^{4}-1\right)$

$9 x^{4}$ is the square of $3 x^{2}$ . Therefore, it can be expressed as below

$\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)$

Now, we can not factorise further the term $\left(3 x^{2}-1\right)$ . Because it will come as $\sqrt{3} x$ (3 is not a square term). Thereby concluding that the complete factorisation for the given expression is $\left(9 x^{4}+1\right)\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)$
