Answer:
alright so you got 2 points! now this is the slope formula! y2-y1/x2-x1
okay let's label your points! (x1 0,y1 -3) (x2 2,y2 1)
let's follow the formula this makes it so we can solve! 1--3/2-0
I understand you may get a decimal but don't use 2.5 use a fraction because teachers seem to like fractions and general decimals can be hard to use (experience lol) 2.5 is 5/2 so this means your slope is 5/2
this formula works every single time and if you memorize it you can do any other problems with 2 points! please memorize y2-y1/x2-x1
The correct answer is the option D, which is: <span>D. 78 cm; 39 cm; 30.3π cm
The explanation is shown above:
1-The formula for calculate the circumference of a circle is:
C=2</span>πr
78π=2πr
2- The radius is:
r=78π/2π
r=39 cm
3- The diameter is:
D=39 cm x 2
D=78 cm
4- The arc length is:
arc length=(140°π/180°)(39 cm)
arc length=30.3π cm
Answer: B. 1 1/2

Answer:
1. 25
2. 10
3. 250
Step-by-step explanation:
Distance formula :√ (x2 - x1)² + (y2 - y1)² √ ()² + ()²
1. LENGTH OF AB :
A = 15,18
B = -5,3
√ (-5 - 15)² + (3 - 18)²
= √ 400 + 225
= 25
2. LENGTH OF AD :
A = 15,18
D = 21,10
√ (21 - 15)² + (10 - 18)²
= √36 + 64
= 10
AREA :
A=w x l
10 x25 = 250
