Answer:

3/4

Step-by-step explanation:

Let's say that r is the radius of the large circle or the diameter of the small circle.

Area of the big circle is $\pi r^{2}$ .

Area of the small circle is $\pi \frac{r}{2} ^{2} = \pi \frac{r^{2}}{4}$ .

The ratio of these 2 circles is 1/4 (calculation in the comments).

So the shaded part represent 1 - 1/4 = 3/4.

ella [17]

Answer:

Not a function

Since x= produces y- -1 and y=-4, the relation (3,-1),(2,5),(4,-6),(3,4),(5,-8) is not a function.

Assume that y varies inversely

Marina86 [1]

Answer:

y = 2

Step-by-step explanation:

y varies inversely with x setup is:

y = k/x

7 = $\frac{k}{2/3}$ (find 'k')

k = 7/1 · 2/3

k = 14/3

use what you know about 'k' and 'x' to solve for 'y'

y = 14/3 ÷ 7/3 (remember to multiply by the reciprocal when dividing fractions)

y = 14/3 · 3/7

y = 2
