Answer:
y = (x - 10)^2 / 100 + 1
Step-by-step explanation:
given:
A suspension footbridge has two 2-meter vertical supports 20 meters apart so the cable connecting 'em will be a convex parabola
The lowest point of the cable, which is the vertex, 1 meter above the path.
y-axis represents the left support and the other vertical support is at x=20
by symmetry, the vertex is mid-pt between the two supports, @ x=20/2=10
so vertex is at (10,1)
vertex form of parabola is y = a(x - h)^2 + k, where (h, k) is the vertex
so y = a(x-10)^2 + 1
at y-axis, x=0, y=2
2 = a(0-10)^2 + 1
2 - 1 = 100a
a = 1/100
so the eqn is y = (x - 10)^2 / 100 + 1
Answer:
-11/10 or -1 1/10
Step-by-step explanation:
Change to improper fractions format
1 6/10 becomes 16/10
2 7/10 becomes 27/10
16/10 - 27/10 = -11/10
-11/10 is also written -1 1/10
25×7.25=181.25
443.75-181.25=262.5
262.5÷25=13.125
$13.13
