It is a function.

You can try plot the graph of that equation and then plot a vertical line. You will see that the graph will only intercept the vertical line only once. That is a function.

Or you can look at the equation. Functions have the equations that start with "y=". Rather say that if you see "y" only (not y² or y³ just only y) then that is mostly a function.

Answer:

see below

Step-by-step explanation:

12 banana muffins, 10 chocolate muffins, 6 blueberry muffins, and 7 vanilla muffins.

The total number of muffins is 35 muffins

P(vanilla) = number of vanilla/ total

= 7/35

= 1/5

This is not likely to occur so it is an unlikely event

Which statement is true? 5 6 8 27 을 ll < - 3 8 4 8 6 6

Neko [114]

Fractions

We are going to be checking each statement in order to find which of them are correct:

We can see that in the drawing 3/8 is smaller than 5/6. Then this statement is false.

We can see that in the drawing 5/8 is smaller than 4/6. Then this statement is false.

<h2>2/6 = 3/8 - 2/6 is equal to 3/8</h2>

We can see that in the drawing 3/8 is bigger than 2/6. Then this statement is false.

<h2>3/6 = 4/8 - 3/6 is equal to 4/8</h2>

We can see that in the drawing 4/8 is equal to 3/6. Then this statement is true.

<h2>Answer: 3/6 = 4/8</h2>

A surveyor leaves her base camp and drives 42km on a bearing of 032degree she then drives 28km on a bearing of 154degree,how far

ValentinkaMS [17]

Answer:

The surveyor is 36.076 kilometers far from her camp and her bearing is 16.840° (standard form).

Step-by-step explanation:

The final position of the surveyor is represented by the following vectorial sum:

$\vec r = \vec r_{1} + \vec r_{2} + \vec r_{3}$ (1)

And this formula is expanded by definition of vectors in rectangular and polar form:

$(x,y) = r_{1}\cdot (\cos \theta_{1}, \sin \theta_{1}) + r_{2}\cdot (\cos \theta_{2}, \sin \theta_{2})$ (1b)

Where:

$x, y$ - Resulting coordinates of the final position of the surveyor with respect to origin, in kilometers.

$r_{1}, r_{2}$ - Length of each vector, in kilometers.

$\theta_{1}, \theta_{2}$ - Bearing of each vector in standard position, in sexagesimal degrees.

If we know that $r_{1} = 42\,km$ , $r_{2} = 28\,km$ , $\theta_{1} = 32^{\circ}$ and $\theta_{2} = 154^{\circ}$ , then the resulting coordinates of the final position of the surveyor is:
