Answer:
r=(A/π)^1/2
Step-by-step explanation:
A=πr^2. When dividing π on both sides, you get r^2 = A/π. Meaning that r = the square root of A/π, or (A/π)^1/2
Answer:
C
Step-by-step explanation:
Answer:
<h2>
y = ²/₃x + ⁴/₃</h2>
Step-by-step explanation:
The point-slope form of the equation of line: y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
y = 2/3x + 1 ⇒ m₁ = 2/3 ⇒ m₂ = 2/3
(-5, -2) ⇒ x₁ = -5, y₁ = -2
point-slope form:
y - (-2) = 2/3(x - (-5))
y + 2 = 2/3(x + 5)
y + 2 = 2/3x + 10/3 {subtact 2 from both sides}
y = 2/3x + 4/3 ← slope-intercept form
First we have to see in both cases what is the cost of one ticket
in the fist case 12.5/5=2.5
in the second case 20.16/8=2.52
therefore 5 tickets for 12.5 is the better deal
