100+6=106%

percent means parts out of 100
106%=106/100=1.06
106% of 29.95=1.06 times 29.95=31.747 or rounded $31.75

costs $31.75

Definition of a radius - the center of a circle to any point to the circumference

Algebra II

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

Step-by-step explanation:

Step 1: Define

Center (2, -3) → x₁ = 2, y₁ = -3

Circumference point (-1, -2) → x₂ = -1, y₂ = -2

In this case, the distance d from the center to the circumference point would be the radius r of the circle.

Step 2: Find Radius r

[Distance Formula] Define equation [Radius]: $\displaystyle r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
Substitute in points [Radius]: $\displaystyle r = \sqrt{(-1-2)^2+(-2--3)^2}$
[Radius] [√Radical] (Parenthesis) Simplify: $\displaystyle r = \sqrt{(-1-2)^2+(-2+3)^2}$
[Radius] [√Radical] (Parenthesis) Subtract/Add: $\displaystyle r = \sqrt{(-3)^2+(1)^2}$
[Radius] [√Radical] Evaluate exponents: $\displaystyle r = \sqrt{9+1}$
[Radius] [√Radical] Add: $\displaystyle r = \sqrt{10}$

Which expression is a difference of squares with a factor of 5x − 8? 25x2 − 16 25x2 + 16 25x2 − 64 25x2 + 64

erastovalidia [21]

Ok so differnce of 2 perfect ssquares are
x^2-y^2=(x-y)(x+y)
we are given
one factor is 5x-8
remember that all you do is square both terms individually to get them
(5x)^2=25x^2
8^2=64
they are difference so
25x^2-64 is answer
