A function can be any straight line except a __________line.
mamaluj [8]

Answer: vertical line.

Step-by-step explanation:

Ok we can define a function f(x) as "something" that maps a given input (we usually call the input "x") into a given output (we usually call the output "y")

We have one rule for functions, each input can be mapped into only one output.

So if for example, for a given value x = A.

f(A) = B

and

f(A) = C

This is mapping the input A into two different outputs, then this is not a function.

Now to the question.

If we have a vertical line (parallel to the y-axis)

This line will have only one value of x associated with it, but all the values of y.

This means that this maps one value of the input into infinite outputs, then this can not be a function.

Is (ab)² equivalent to ab², why or why not?
Montano1993 [528]

(ab)² and ab² are not equal. When you have something in parentheses being squared, you have to square everything inside, so in the case of (ab)², you have to "distribute" the ² to both variables inside. That gives you a²b², not just ab².

If the abstract way is kind of confusing for you, just pick two random numbers for a and b and plug them in to test it. Say a = 3 and b = 4. Then

(3*4)² = 3*4²

(12)² =  3*16

144 ≠ 48

a map has a scale of 1cm:11.5km.two cities are 5.5cm apart on the map.to the nearest tenth of a kilometer, what is the actual di
Zinaida [17]

Answer:

The actual distance between the two places to the nearest tenth of a kilometer is 63.3 km

Step-by-step explanation:

Here, we want to get the actual distance between two places on a map, given the scale used to draw the map and the distance of both places on the map, in terms of the scale.

The scale used here is 1cm to 11.5km

Since 1cm = 11.5km

then 5.5cm = x km

Thus ; x = 5.5 * 11.5

x = 63.25 km

Our answer in wanted to the nearest tenth of a kilometer so the answer is 63.3 km
