The equation f(x) = 3x2 − 24x + 8 represents a parabola. What is the vertex of the parabola?
s2008m [1.1K]

\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ f(x)=\stackrel{\stackrel{a}{\downarrow }}{3}x^2\stackrel{\stackrel{b}{\downarrow }}{-24}x\stackrel{\stackrel{c}{\downarrow }}{+8} \qquad \qquad  \left(-\cfrac{ b}{2 a}~~~~ ,~~~~  c-\cfrac{ b^2}{4 a}\right) \\\\\\ \left(-\cfrac{-24}{2(3)}~~,~~8-\cfrac{(-24)^2}{4(3)}  \right)\implies (4~~,~~8-48)\implies (4~~,~-40)

The difference between the acute angles of a right angled triangle is 72degree find them .
MaRussiya [10]

The 2 angles add up to 90 degrees so

x + y = 90, also:-

x - y = 72 (given)

adding the 2 equations:-

2x = 162

x = 81

and therefore

y + 81 = 90

y = 9


Answer the 2 angles are 81 and 9 degrees

Multiple choice question please answer it for me
timofeeve [1]
The answer is the second choice, or B; 240 ft^2.

You have to find the area of all four triangles and just add those all together. 

Two of the triangles have an area of 
5*16=80
Multiply that by two
80*2=160

The other two smaller triangles have an area of 
8*5=40
Multiply that by 2 also
40*2=80

Add 160+80 and the answer is 240.
