Which number is irrational
alexgriva [62]

Answer: Choice A) sqrt(17)

The square root of 17 is irrational because we cannot write this number as a fraction of two whole numbers (see note below). With something like choice B, we can do so and that would be 6/99; while choice C simplifies to 7 which is equivalent to 7/1. Choice D isn't fully visible, but it appears to be a fraction of two whole numbers.

Note: the denominator of the fraction cannot be 0.

The height of a hill, h(x), in a painting can be written as a function of x, the distance from the left side of the painting. Bo
vampirchik [111]
I suspect there's more to this problem than you've shared.  Based only upon what you have shared:

"h(x) = the height, in inches) of the hill shown in the painting, where x is the distance from the left side of the painting of the point on the hill."

Double check to ensure that you've copied the entire problem to be solved.

What do s the constant proportionality in the equation y= 5x
kolezko [41]

5 is the proportionality constant in the given equation

Step-by-step explanation:

There are two types of proportion

  1. Direct proportion
  2. Indirect Proportion

In direct proportion, the increase or decrease in one quantity also cause increase or decrease in other quantity.

IT can be mathematically written as:

y∝x

When the proportionality symbol is removed, proportionality constant is introduced

y=kx

Here k is the proportionality constant

If we compare the general form with the given equation y=5x

Then we can see that k=5

Hence,

5 is the proportionality constant in the given equation
