You stick the number of x into the function to produce the answer so

x=-8, y=-4
x=-4, y=-3
x=0, y=-2
x=4,y=-1
x=8,y=0

The function f(t) = 4t2 − 8t + 6 shows the height from the ground f(t), in meters, of a roller coaster car at different times t.

gregori [183]

Answer:

The correct option is 3.

Step-by-step explanation:

The vertex form of a parabola is

$f(x)=a(x-h)^2+k$ .... (1)

where a, h, and k are integers, and interpret the vertex of f(t). (h,k) is the vertex of the parabola.

The given function is

$f(x)=4t^2-8t+6$

It can be written as

$f(x)=4(t^2-2t)+6$

If an expression is defined as $x^2+bx$ , then we need to add $(\frac{b}{2})^2$ to make it perfect square.

In the expression $t^2-2t$ the value of b is -2. So, we nned to add and subtract $(\frac{-2}{2})^2$ in the parenthesis.

$f(x)=4(t^2-2t+1^2-1^2)+6$

$f(x)=4(t^2-2t+1)+4(-1)+6$

$f(x)=4(t-1)^2-4+6$

$f(x)=4(t-1)^2+2$ .... (2)

The vertex form of the parabola is $f(x)=4(t-1)^2+2$ .

From (1) and (2), we get h=1 and k=2. It means the vertex of the parabola is (1,2). Vertex of upward parabola is point of minima. So the minimum height of the roller coaster is 2 meters from the ground.

Therefore the correct option is 3.

What is the area:

pychu [463]

Triangle formula: 1/2base(height)
So 1/2(6) * 9
3*9 = 27ft^2
Parallelogram formula: length(width) or base(height)
So 18(13)= 234m^2
Triangle formula above so 1/2(20)*9
So 10*9 = 90in^2

You are planning a summer cookout and decide to serve quarter-pound hamburgers. If you buy 5 and a 1/2 pounds of hamburger meat,

polet [3.4K]

Well, namely, you've got 5 and 1/2 lbs of meat, and each burger will be 1/4 lb, so how many times 1/4 goes into 5 and 1/2?

let's first make the 5 and 1/2 mixed fraction to "improper" and divide them both.

$\bf \stackrel{mixed}{5\frac{1}{2}}\implies \cfrac{5\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{11}{2}}\\\\
-------------------------------\\\\
\cfrac{\quad \frac{11}{2}\quad }{\frac{1}{4}}\implies \cfrac{11}{2}\cdot \cfrac{4}{1}\implies \cfrac{11}{1}\cdot \cfrac{2}{1}\implies \cfrac{22}{1}\implies \stackrel{\textit{burgers}}{22}$

don't forget the bbq sauce.
