(btw if i write 4x^3 it means 4x to the power of 3)

1) (2x+3)(x-2)
2x^2 -4x + 3x -6
2x^2 -x -6

2) x^2 +10x +24
(x+12)(x-2)

3) 6x^2 -13x +6
(2x )(3x ) not sure on this one

4) x^2 +8x +15
(x+3)(x+5)
x= -3 x=-5

5) x^2 -4x -45
(x+5) (x-9)
x=-5 x=9

hope this helps, if you need any help understanding what happens just ask

Let V=ℝ2 and let H be the subset of V of all points on the line 4x+3y=12. Is H a subspace of the vector space V?
sergejj [24]

Answer:

No, it isn't.

Step-by-step explanation:

We have V=IR^{2} and let H be the subset of V of all points on the line

4x+3y=12

We need to find if H is a subspace of the vector space V.

In IR^{2} all the possibilities for own subspace of the vector space IR^{2} are :

  • IR^{2} itself.
  • The vector 0_{IR^{2}}=\left[\begin{array}{c}0&0\end{array}\right]
  • All lines in IR^{2} that passes through the origin  (  0_{IR^{2}}=\left[\begin{array}{c}0&0\end{array}\right]  )

We know that H is the subset of IR^{2} of all points on the line 4x+3y=12

If we look at the equation, the point \left[\begin{array}{c}0&0\end{array}\right] doesn't verify it because :

4x+3y=12\\4(0)+3(0)=12\\0=12

Which is an absurd. Therefore, H doesn't contain the origin (and H is a line in IR^{2}). Finally, it can't be a vector space of V=IR^{2}

The floor of a gazebo is in the shape of a regular octagon. The perimeter of the floor is 72 feet. The distance from the center
Katyanochek1 [597]
The length of one side of the octagon is given by:
 L = 72/8

L = 9
 Then, the apothem can be determined using the Pythagorean theorem in the following way:
 11.8 ^ 2 = (9/2) ^ 2 + a ^ 2

 Clearing to have:
 a ^ 2 = 11.8 ^ 2 - (9/2) ^ 2
 a = \sqrt{11.8 ^ 2 - (9/2) ^ 2}
 a = 10.91
 Then, the area is given by:
 A = (8) * (1/2) * (L) * (a)

 Where,
 L: length of the octagon sides
 a: apotema
 Substituting values:
 A = (8) * (1/2) * (9) * (10.91)

A = 392.76 feet ^ 2
 Answer:
 
the approximate length of the apothem is:
 
a = 10.91 feet
 
The approximate area of the floor of the gazebo is:
 
A = 392.76 feet ^ 2
