Answer:
So, The answer would be 1=k
Step-by-step explanation:
My step is to make a T-chart, as u make it put X on one side and Y on the other
So what i did was i put 0 for both of them because it had start at 0
then i followed the line to the dot as i did that It has 6,6 so then i figured out what multiply all those number and the answer was 1=k
And another way you could do it was to make 6,6 and fraction like 6/6 then divde them both and get 1=k
So you would put the answer as 1
thats it Answer-1

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
3-(-4) = 3 + 4
so, as an addition problem it is 3 + 4
Answer:
To determine the explicit rule for the arithmetic sequence of 20.5, 16, 11.5, 7, 2.5, ..., the following logical reasoning must be performed:
20.5 - 16 = 4.5
16 - 11.5 = 4.5
11.5 - 7 = 4.5
7 - 2.5 = 4.5
Thus, the explicit rule of the arithmetic sequence is that the numbers are gradually subtracted by 4.5, with which the next number of said sequence would be -2.
