Answer:

c) y=1/2x

Step-by-step explanation:

A direct variation is a linear function that is written in the form of y=kx, so from the options that we have we have to search for linear functions, that rules out option "A", and now that is written in Y=KX in option b we have a liner function that is written y=X+B which is a constant, so that wouldn´t be and option D is Y=k/x so that one is also wrong, our correct option would be y=1/2x

The answer is c) y=1/2x because a direct variation is in the formula b=ka where k is a constant.

You’re baking a circular cake for a party. Your cake can be any size you want. What will the radius of your cake be and how many
REY [17]
What will the radius of your cake be?

This is a problem of geometry. Given that the cake is circular, the greater the cake the greater the radius of it. So, as shown in the figure 1, the radius will be the distance from the center to any extreme point of the circle.

How many slices will you be able to cut?

The total area of a circle is given by:

A= \pi  r^{2}

We need to fin how many slices will be cut, so let's calculate the area of the circular sector which can be obtained simply applying rule of three, so:

A_{cs}= \pi r^{2}( \frac{\theta}{2\pi})= \frac{r^{2}\theta}{2}

Let's name n the number of slices, if we divide the total area by n this result, each area  must equal, then:

\frac{\pi r^{2}}{n}=\frac{r^{2}\theta}{n}

Finally, we will be able to cut:

n= \frac{2\pi}{\theta} Slices
