(x - x₀)² + (y - y₀)² = r²
x₀=-4; y₀=3; r=5;
(x - (-4))² + (y - 3)² = 5²
(x + 4)² + (y - 3)² = 25
Answer:
90pi
Step-by-step explanation:
SA = pi r l +B
we know the radius is 5
We need to find the slant height using the Pythagorean theorem
a^2+b^2 = c^2
5^2+12^2 = l^2
25+144= l^2
169 = l^2
Taking the square root of each side
sqrt(169) = sqrt(l^2)
13 = l
B is the area of the base
B = pi r^2 = pi (5)^2 = 25 pi
SA = pi r l +B = pi (5)*13 + 25pi
=65pi +25pi = 90pi
Answer:
≈ 23 years
Step-by-step explanation:
Initial price= $995
Value increase= 3.1%
a) $995 +3.1%= $995*1.031= $1025.85
b) $995*1.031^x= $2000
1.031^x= 2000/995
1.031^x= 2.01
x= log 2/log 1.031= 22.7 ≈ 23 years
