Answer:

y = 2x

Step-by-step explanation:

Given y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition when x = 4, y = 8, that is

8 = 4k ( divide both sides by 4 )

2 = k, thus

y = 2x ← equation of proportion

Which statement accurately describes how adding a number, n, to the function f(x)=sin(x) affects its graph?

Hitman42 [59]

The <em>correct answer</em> is:

A) There is a vertical shift of n units.

Explanation:

When a parent function is transformed, each type of transformation results ina different change in the graph.

The parent function in this question is f(x) = sin(x).

Adding n units to the end of this function would result in f(x) = sin(x) + n.

When a function is transformed by adding a constant to the end of a function results in a vertical shift by that number of units. In this case, it would be a vertical shift n units.

Find the distance between the points (-5, 0) and (-4, 1).

choli [55]

The formula of a distance between two points A and B is :

$AB=\sqrt{(x_{B}- x_{A})^2 +( y_{B}- y_{A})^2 }$

You should this formula by heart.

Then, you just have to apply it ! :D

Here :

$x_{A}=-5$
$y_{A} =0$

$x_{B} =-4$
$y_{B}= 1$

Therefore :

$\sqrt{(-4-(-5))^2+(1-0)^2}$
$= \sqrt{1^2+1^2}$
$= \sqrt{1+1}$
$= \sqrt{2}$

In short, the answer would be the first option : $\sqrt{2}$ .

Hope this helps !
