Answer:
Slope: = 3/10x
y-intercept: = -7/10
Step-by-step explanation:
10y = -3x - 7
y = -3/10x - 7/10
Slope: = 3/10x
y-intercept: = -7/10
Answer:
384000
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let x be the track straights lengths
Let y be the track ends diameter and the other rectangle side lengths.
1800 = 2x + πy
y = (1800 - 2x) / π
A = xy
A = x((1800 - 2x) / π
A = (1/π)(1800x - 2x²)
dA/dx = (1/π)(1800 - 4x)
0 = (1/π)(1800 - 4x)
0 = 1800 - 4x
4x = 1800
x = 450 m
y = (1800 - 2(450)) / π
y = 900/π or approximately 286.5 m
