Find the distance between the two points in simplest radical form. (1, -7) and (7,0)

Answer:

The <u>distance</u> <em>between</em> the two given points is equal to √85.

Step-by-step explanation:

Let's recall what the distance formula is:

\displaystyle \huge\math\boxed{d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2} }

We are defined our two points as:

  • (x₁, y₁) → (1, -7)
  • (x₂, y₂) → (7, 0)

We can rewrite this into our different "variables":

  • x₁ = 1
  • y₁ = -7
  • x₂ = 7
  • y₂ = 0

Now given our distance formula and our variables, we can find the distance between the two points:

\displaystyle\huge\begin{aligned}d & = \sqrt{(1 - 7)^2 + (7 - 0)^2} \\& = \sqrt{(-6)^2 + (7)^2} \\& = \sqrt{36 + 49} \\& = \math\boxed{\sqrt{85}} \\\end{aligned}

∴ since the radical is already in its simplest form, our distance between the two points is equal to √85.

Hope this helps!

<h3>✞︎ <u>Solution</u> ✞︎</h3>

➪ In order to calculate the required distance use the the distance formula

\displaystyle{\implies\:\underline{\boxed{ \purple{\bf\:\bigg \lgroup\: \: d = \sqrt{(x_2 - x_1 {)}^{2} \:  +  \: ( y_2 - y_1 {)}^{2}  \:} \:  \bigg\rgroup} \: }}}

❒ <u>Where</u> ❒

\rm \longrightarrow (x_1 ,y_1) \: and \:(x_2,y_2) are 2 coordinate points.

❖ The <u>2 points</u> given here are

  • ➪ ( 1 , -7 )

<u>and</u>

  • ➪ ( 7, 0 )

❖ <u>Assume that</u> ,❖

\rm \longrightarrow (x_1 ,y_1)  =( 1 ,-7)   \:  \\  \rm \: and  \\ \rm\longrightarrow \:(x_2,y_2) = (7,0)

: :  \rm \implies \: d =  \sqrt{(7 -1 {)}^{2}   +  {(0 -( - 7)) }^{2} }

: :  \rm \implies \: d =  \sqrt{(6 {)}^{2}   +  {(7)}^{2} }

: :  \rm \implies \: d =  \sqrt{(36 {)}  +  {(49)}}

: :  \bf \implies \: d =  \sqrt{85} \longleftarrow \rm in \: radical \: form

\dfrac12(10x + 20y +10z) = 2 1 ​ (10x+20y+10z)=start fraction, 1, divided by, 2, end fraction, left parenthesis, 10, x, plus, 20
iragen [17]

Answer:

5x + 10y + 5z

Step-by-step explanation:

Given the expression

\frac{1}{2}(10x+20y+10z)\\

Expand the parenthesis using the distributive law;

\frac{1}{2}(10x)+ \frac{1}{2}(20y)+\frac{1}{2}(10z)\\= \frac{10x}{2} + \frac{20y}{2} + \frac{10z}{2}\\= 5x + 10y + 5z

Hence the required solution is 5x + 10y + 5z

tiny-mole [99]

Answer:

A(an)   <u> altitude  </u>  of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)

Step-by-step explanation:

AN ALTITUDE -  An altitude of a triangle is a line segment that passes through a vertex and is perpendicular to (i.e. forms a right angle with) the base line (the side opposite the vertex). The expanded base of the altitude is the line that contains the opposing side. The foot of the altitude is the point where the extended base meets the altitude. The area of a triangle can be calculated using altitudes: one half of the product of an altitude's length and its base's length equals the triangle's area. As a result, the longest altitude is perpendicular to the triangle's shortest side. Through trigonometric functions, the heights are also connected to the triangle's sides.

<u>Hence , the answer is an altitude .</u>
