Triangle can be formed with angle measures of 32 degrees, 126 degrees, and 32 degrees

Mathematics

Alexus [3.1K]3 years ago
6 0

Answer:

No triangle can be formed with these angles.

Step-by-step explanation:

There must be  180 degrees in a triangle.

32 + 126 + 32

= 126 + 64

= 190 degrees - so this cannot form a triangle.

A parabola intersects the x-axis at x=3 and x=9 what is the x-coordinate of the parabola's vertex?
KiRa [710]

Here we are given the x intercepts at x=3 and x=9

So let us try to make quadratic equation for this using given information.

We have factors in the form (x-a)(x-b)

where a and b are x intercepts given to us.

So rewriting in factored form:

y=(x-3)(x-9)

Now let us simplify it:

y=x^{2}-12x+27

Let us find the vertex now,

For a quadratic equation of the form:

y=ax^{2}+bx+c

For x coordinate , we have the formula,

x=\frac{-b}{2a}

So using this formula for our equation,

x=\frac{-(-12)}{2(1)}

So x = 6

Answer: The x-coordinate of the parabola's vertex is 6.

Step-by-step explanation:

= 2(x + 7) – 18x

= 2x + 14 -18x

= -16x + 14

or

= 2(7-8x)

Help! What is the answer to: <br> 4x^2 + 9x - 1 = 0
nataly862011 [7]
I hope this helps you




a=4


b=9


c= -1



disctirminant =b^2-4ac


disctirminant =9^2-4.4. (-1)


disctirminant =97


x1=-9+square root of 97/2.4= -9+square root of 97/8


x2= -9-square root of 97/2.4= -9-square root of 97/8
