Need help parabola and its vertex

AVprozaik [17]

$y + 13 = 2(x - 1)^2$

use the equation: $(y_{2} - y_{1}) = m({x_{2} - x_{1})^2$

$(-11 + 13) = m(0 - 1)^2$

$2 = m(1)^2$

$m = 2$

$y + 13 = 2(x - 1)^2$

substitute y for 0, since x-intercepts occur on the x-axis, or the line y = 0

$0 + 13 = 2(x - 1)^2$

$13 = 2(x - 1)^2$

$13 = 2(x^2 - 2x + 1)[tex]\\[tex]13 = 2x^2 - 4x + 2$

$2x^2 - 4x - 15$

use the quadratic equation (can't type it out on brainly, if you don't know, look it up)

$x = 1 - \sqrt{ \frac{13}{2} }, 1 + \sqrt{ \frac{13}{2} }$

The answer is: $(1 - \sqrt{ \frac{13}{2} },0)$ and $(1 + \sqrt{ \frac{13}{2} },0)$

Oliver is building a box kite. The frame of the kite has the dimensions shown. He covered the sides of the kite (but not the top

11Alexandr11 [23.1K]

Answer: 54000 cube cm

Step-by-step explanation:
Let h be the height of the box kite,
Also the length of one face = 30 cm,
Hence, the total area of the kite box that is covered by the fabric
= 4 × Area of one face
= 4 × 30 × h
= 120 h
According to the question,
120 h = 7200
h = 60 cm
Hence, the height of the box = 60 cm,
The volume inside the kite = The base area of the box × Its height
= 30² × 60
= 900 × 60
= 54000 cm³
