How to find the distance AB ? A(0,1) B(2,-3)

Anastaziya [24]

Hey there!!

Distance formula :

$\sqrt{(y2-y1)^{2} + (x2-x1)^{2} }$

Coordinates given :

( 0,1 ) and ( 2,-3 )

( y2 = -3 ; y1 = 1 ) ( x2 = 2 ; x1 = 0 )

Plugging in the values :

... $\sqrt{(-3-1)^{2}+(2-0)^{2} }$

... $\sqrt{(-4)^{2}+(2)^{2} }$

... $\sqrt{16+4}$

... $\sqrt{20}$

... $\sqrt{5}$ × $\sqrt{4}$

... 2 $\sqrt{5}$ units is the distance.

Hope my answer helps!!

The variables A, B, and C represent polynomials where A = x2, B = 3x + 2, and C = x – 3. What is AB – C2 in simplest form?

Vladimir [108]

AB = X^2(3X +2)

C^2 = (x - 3)^2

AB - C^2 = 3x^3 + 2x^2 - (x^2 - 6x + 9)

= 3x^3 + x^2 + 6x - 9

The vertex of y=x^2+12x+32

ollegr [7]

Answer:

The vertex is y=-4

Step-by-step explanation:

The vertex is the minimum point of the graph of the quadratic equation.

Let's first find the like of symmetry.

dy/dx=2x+12

2x+12=0

2x=-12

x=-6

Now plug -6 into the quadratic equation

y=(-6)²+12(-6)+32

y=-4
