By looking at the formula you can see that the quadratic part is 0 if you fill in x=3 (you know, 3-3 = 0). The outcome of the formula then becomes y= 0+5.

That gives us point (3,5) as the top of the parabola. So there you go, answer A.

Consider the following problem: a box with an open top is to be constructed from a square piece of cardboard, 3 feet wide, by cu

Answer:

) See annex

b) See annex

x = 0,5 ft

y = 2 ft and

V = 2 ft³

Step-by-step explanation: See annex

c) V = y*y*x

d-1) y = 3 - 2x

d-2) V = (3-2x)* ( 3-2x)* x ⇒ V = (3-2x)²*x

V(x) =( 9 + 4x² - 12x )*x ⇒ V(x) = 9x + 4x³ - 12x²

Taking derivatives

V¨(x) = 9 + 12x² - 24x

V¨(x) = 0 ⇒ 12x² -24x +9 = 0 ⇒ 4x² - 8x + 3 = 0

Solving for x (second degree equation)

x =[ -b ± √b²- 4ac ] / 2a

we get x₁ = 1,5 and x₂ = 0,5

We look at y = 3 - 2x and see that the value x₂ is the only valid root

then

x = 0,5 ft

y = 2 ft and

V = 0,5*2*2

V = 2 ft³

When 5x2+2=4x is solved using the quadratic formula, what are the values of a,b, and c?

viktelen [127]

Hey there,

What are the values of a, b and c?

5x² + 2 = 4x

5x² + 2 - 4x = 4x - 4x

5x² - 4x+ 2 = 0

Quadratic général equation:

ax² + bx + c = 0

a = 5
b = -4
c = 2

I hope this helps ✅(◠‿◕)
