Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point A (2, -1)

Point B (-4, 2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(-4-2)^2+(2+1)^2}$
Subtract/Add: $d = \sqrt{(-6)^2+(3)^2}$
Exponents: $d = \sqrt{36+9}$
Add: $d = \sqrt{45}$
Simplify: $d = 3\sqrt{5}$

Which are the roots of the quadratic function f(q) = q2 – 125? Select two options.

Assoli18 [71]

Answer:

±11.18

Step-by-step explanation:

the function is:

$f(q)=q^2-125$

and to find the roots we need to find which values of $q$ makes the function result in zero:

$q^2-125=0$

solving for $q$ :

$q^2=125\\q=\sqrt{125}$

A square root has two solutions, one positive and one negative, so the solutions are:

$q=$ ± $\sqrt{125}$ ≈ ±11.18

the roots of the quadratic equation are +11.18 and -11.18
