Answer:

Explanation:

3. Find LCM of (30, 9):

30 = 2 x 3 x 5
9 = 3 x 3

Thus : LCM(30, 9) = 2 x 3 x 3 x 5 = 90

Therefore, in 90 days he will has both activities again.

4. Determine whether its possible to construct a triangle with the given length.

a.
8 + 9 > 11 (true)
8 + 11 > 9 (true)
9 + 11 > 8 (true)

Thus 8,9 and 11 can be construct as a triangle.

b.
4 + 5.1 > 12.5 (false)
4 + 12.5 > 5 (true)
12.5 + 5 > 4 (true)

Thus, 4, 5.1 and 12.5 cannot be constructed as a triangle.

find the x-intercepts and the coordinates of the vertex for the parabola Y equals negative X squared plus 8X -12. If there’s mor

Oksanka [162]

Answer:

x = 2, and 6

x = 2 , 6

Step-by-step explanation:

The quadratic function to analyze is: $y = -x^2+8x-12$

In order to find where the corresponding parabola intercepts the x axis, we set it equal to zero (y = 0):

$y = -x^2+8x-12\\0 = -x^2+8x-12\\x^2-8x+12=0$

This equation is easy to solve by factoring. We look for a air of integer numbers whose product equals the constant term "12", and whose combinig renders the coefficient of the middle term of the trinomial "-8".

The two such numbers are "-2" and "-6". We use them to split the middle term, and then solve by factoring by grouping:

$x^2-8x+12=0\\x^2-2x-6x+12=0\\(x^2-2x)+(-6x+12)=0\\x(x-2)-6(x-2)=0\\(x-2)(x-6)=0$

For the product of two factors to render zero, we need either one to be a zero.This means that (x-2)=0 (that is x = 2), or (x-6)=0 (that is x = 6).

So, there are two x-intercepts: x= 2, and 6
