PLEASE HELP!!! I WILL GIVE BRAINY!!!

The first one is 4/3

We can solve by,

{x}^{2} \times 180 = 320

x = \frac{4}{3}

{ \frac{4}{3} }^{2} \times 180 = 320 = true

~~

The second one is 35.

Idk how to explain...

~~

The third one is a 6 - gon therefore cannot be C or D.

I'd say the third one is A., it looks like it's caving in.

nina wants to put color tiles on a square . 3 color tiles fit acroos the top of the square . how many rows and colum of tiles wi
pickupchik [31]
She will use 3 rows of 3 squares, for a total of 9 squares.

Since the shape she is covering is a square, all of the sides are equal.  If 3 square tiles fit across the width of the top, then 3 square tiles fit across the length of it as well.  This makes 3 by 3, or 9 squares.

please just give me the answer is homework please help1)vertex 2)axis of symmetry 3)x-intercepts 4)maximum or minimum 5)max/min
aniked [119]

Answer:

See explanations below

Explanation:

Vertex of a graph is the lowest point on the curve. The vertex occurs at (1.75, -2.5)

The axis of symmetry is the point on the x axis of the line that cuts through the minimum point. The axis of symmetry occurs at x = 1.75

x intercept is the point where the curve cuts the x axis. The x intercept occurs at x = 0 and x = 2.5

To get the minimum, we will use the formula;

c - b^2/4a

The equation of the curve is expressed as;

(x-0)(x-2.5)

= x (x-2.5)

= x^2 - 2.5x

a = 1, b = -2.5, c = 0

minimum = 0 - (-2.5)^2/4(1)

minimum = -6.25/4

minimum = -1.5625

Minimum value occurs at the base of the parabola. The minimum value of the function is -2.5

y intercept is the point where the curve cuts the y axis. The y-intercept occurs at y = 0.
