So we see the ratio of the sides of two similar octagons is 2:5 so let's say the first octagon has a side of 2 and the other has a side of 5. 2*8 = 16 and 5*8 = 40. 16:40 = 4:10 = and is again 2:5. So the answer is 2:5.

The equation 2y = 8x represents a proportional relationship. What is the constant of proportionality?
Sphinxa [80]

Answer:

C) 4

Step-by-step explanation:

Given equation:

2y=8x

The above equation represents proportional relationship.

To find the constant of proportionality.

Solution:

<em>The equation representing proportional relationship is given by:</em>

<em>y=kx</em>

<em>where k represents constant of proportionality.</em>

So, in order to find the value of k for the given proportionality relationship, we will solve for y

We have:

2y=8x

Solving for y

Dividing both sides by 2.

\frac{2y}{2}=\frac{8x}{2}

y=4x

∴ k=4

Thus, the constant of proportionality = 4.

A delivery truck driver charges a fixed base price of $6 for 2 miles.
stiv31 [10]

Answer:

Option B.

Step-by-step explanation:

It is given that a delivery truck driver charges a fixed base price of $6 for 2 miles.

After 2 miles, he charges an additional $2 for every mile and after 6 miles, he charges an additional $4 for every mile.

We need to describe the cost of the delivery truck between 1 mile and 2 miles.

In the given graph x-axis represents the distance in miles and y-axis represents the cost in dollars.

From the given graph it is clear that the value of function is constant between x=1 and x=2.

It means the cost of the delivery truck between 1 mile and 2 miles is constant.

Therefore, the correct option is B.

The graph of y = tan ⁡(x − π / 2) compared to the graph of y = tan ⁡x has:
vodomira [7]

Answer:

Last Option moved \frac{\pi}{2} units right

Step-by-step explanation:

If we have a function f(x) and we want to move it horizontally then we make the transformation:

y = f (x + h)

If h then the graph of f(x) moves horizontally h units to the right

If h> 0 then the graph of f(x) moves horizontally h units to the left.

In this case we have the function y = tan (x) and the transformation is performed to obtain y = tan(x- \frac{\pi}{2})

Notice that in this transformation

h

<u><em>Then the graph of y = tan (x) moves horizontally \frac{\pi}{2} to the right</em></u>
