Oduvanchick [21]

Answer:

y=2, the equation of  a line which is perpendicular to the line 3x+5=0

A(-5/3,2)  the  foot of the perpendicular from B to the line

Step-by-step explanation:

d1 : 3x+5=0, so 3x=-5, x=-5/3

y=2, the equation of  a line which is perpendicular to the line 3x+5=0

A(-5/3,2)  the  foot of the perpendicular from B to the line

The center of an ice rink is located at (0, 0) on a coordinate system measured in feet. sandi skates along a path that can be mo
WARRIOR [948]

The answers to the question are are the equations

y = 0.08x²-1.6x+13

y = 0.08(x-10)²+5

<h3>How to solve for the system of equations</h3>

David starts at (20, 13) and skates along a path that can be modeled by a quadratic function with a vertex at (10, 5).

Vertex form of quadratic function is

y = a(x-h)^2+k

13 = a(x-10)²+5

let x = 20

a(20-10)²+5

13 = 100a + 5

take like terms

13 - 5 = 100a

8 = 100a

divide through by 100

a = 0.08

hence the equation would be

y = 0.08(x-10)²+5
