What’s the distance between (3,4) , (7,2)

Reptile [31]

Answer:

$D= 4.47$

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (3,4)$

$(x_2,y_2) = (7,2)$

Replacing these values in the distance formula

$D =\sqrt{(7-3))^2+(2-4)^2}$

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

$D =\sqrt{16+4}$

$D =\sqrt{20}$

$D= 4.47$

Find the zeros of the following polynomial x^2-2x+1

muminat

If the polynomial is of the form x^2+bx+c (ie., no factor in front of the x^2!!) then you can look for numbers that add up to b and multiply to c.

So in this case: what two numbers, when added, give -2 and when multiplied, give 1? A little trial and error gives you -1 and -1.
So the factorization is (x-1)(x-1). This is zero for x=1. There is only one zero.
