Dominik [7]4 years ago
3 0

Answer:

  a = 9/2

Step-by-step explanation:

In order for the equation to be true, the value of the scalar multiplier must be ...

  15/3 = -10/-2 = 35/7 = 5

So, you're solving ...

  (2/3)a + 2 = 5

  (2/3)a = 3 . . . . . . subtract 2

  a = 9/2 . . . . . . . . multiply by 3/2

What is the constant of proportionality between y and x in the graph?
umka2103 [35]

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

A suspension footbridge has two 2-meter vertical supports 20 meters apart. The lowest point of the cable connecting them is 1 me
maw [93]

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

What is the explicit rule for the arithmetic sequence? 20.5, 16, 11.5, 7, 2.5, ...
Naily [24]

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.
