Find the distance CD rounded to<br> the nearest tenth.<br> C = (7,-4) and D = (-8,-5)<br> CD = [?]
quester [9]

Answer:

CD= 15.03

Step-by-step explanation:

x1=7, x2= -8

y1=-4, y2=-5

distance CD= √(x2- x1) 2+ (y2-y1)2

= √( -8-7)2 + [-5-(-4)]2

= √(15)2+ (-5+4)2

= √225+ (1)2

= √225+1

= √226

= 15.03

Find the distance between the points (5, -5) and (-7,4).
abruzzese [7]

Answer:

<h2>The answer is 15 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

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

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(5, -5) and (-7,4)

The distance between them is

d =  \sqrt{ ({5 + 7})^{2}  +  ({ - 5 - 4})^{2} }  \\  =  \sqrt{ {12}^{2}  + ( { - 9})^{2} }  \\  =  \sqrt{144 + 81}  \\  =  \sqrt{225}  \\  = 15 \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>15 units</h3>

On a basketball court the free throw line is marked off geometrically this area of the court is called a key and is topped
Alenkinab [10]

Step-by-step explanation:

Arc length formula is

s = rx

where x is radinas.

A semi circle has a radian measure of

\pi

The radius is half of the diameter, 12 so the radius is

12 \times  \frac{1}{2}  = 6

So the arc length is

6 \times \pi = 6\pi

Area of semi circle is

\frac{1}{2} \pi {r}^{2}

where r is the radius.

\frac{1}{2} \pi6 {}^{2}

\frac{1}{2} 36\pi

18\pi
