Write an equation for a parabola that has a vertex (1, 2) and passes through the point (3, -6).
Alex

Answer:

y= -2x²+4x.

Step-by-step explanation:

the common equation of the parabola is y=ax²+bx+c, where a, b, c - numbers.

1) the coordinates of the vertex are:

x_0=-\frac{b}{2a} \ and \ y_0=\frac{4ac-b^2}{4a}.

2) if according to the condition x₀=1, then b= -2a.

If according to the condition y₀=2, then   2=\frac{4ac-b^2}{4a}=\frac{4ac-4a^2}{4a}=c-a;

it means that c=a+2.

3) if b= -2a; c=a+2 and the point (3;-6) belongs to the given parabola, then it is possible to substitute them into the common equation of the parabola:

-6=3²*a-6a+a+2; ⇔ a= -2.

4) if a= -2, then b=-2a=4, and c=a+2=0.

5) if a=-2, b=4 and c=0, then the required equation of the parabola is:

y= -2x²+4x.

7.For tire size P225/45R17, give the following: Width(mm): _______________ Aspect Ratio (%): _______________ Height (in.): _____
irakobra [83]

The width is the first numbers.

Width = 225 mm

Aspect ratio is the second number.

Aspect ratio is 45

Aspect ratio is width / height.

You have the ratio and width so you can calculate the height:

Multiply the width by the ratio:

Height = 225 x 0.45 = 101.25 mm

101.25/25.4 = 3.98 inches

The rim

Diameter is the last number

Rim diameter = 17 inches

So the overall height would be approximately 17 + 3.98 + 3.98 = 24.96 inches

Round the answers as needed.
