The distance between two points knowing theirs coordinates:
AB =√[(x₂-x₁)² +(y₂-y₁)²]; ===>A(-2,4) & B(0,-6) Given
A(x₁,y₁) & B(y₂,y₁)
AB =√[(0-(-2))²+(-6-4)²] =√(104) = 10.198 ≈ 10.2
Answer:
y=sqrt(1/2x-25/2), -sqrt(1/2x-25/2).
Step-by-step explanation:
y=2x^2+25
x=2y^2+25
2y^2=x-25
y^2=1/2x-25/2
y=sqrt(1/2x-25/2), -sqrt(1/2x-25/2)
Answer:
<h2>30 ft. tall</h2><h2 />
Step-by-step explanation:
ratio and proportion:
<u>20 ft. long</u> = <u> 4 ft. long</u>
x tall 6 ft. tall
4 (x) = 20 (6)
x = 120 / 4
x = 30 ft. tall
