Answer:

see explanation

Step-by-step explanation:

Using the ratio equality for circles

\frac{arc}{C} = \frac{angleatcentre}{360}

(a)

Note the angle at the centre of the shaded arc is 360° - 90° = 270°, thus

\frac{45}{C} = \frac{270}{360} = \frac{3}{4} ( cross- multiply )

3C = 180 ( divide both sides by 3 )

C = 60 mm

(b)

Note the angle at the centre of the shaded arc is 360° - 135° = 225°, thus

\frac{3.3}{C} = \frac{225}{360} ( cross- multiply )

225C = 1188 ( divide both sides by 225 )

C = 5.28 cm

For what values of b the relation R:{(b^2, 5), (5b, 6)} is not a function?
xenn [34]

Answer:

B=5,0.

Step-by-step explanation:

It's not that hard. It's just that it might throw you off a bit with the R and the other things. Functions if you don't remember are where the coordinates don't have the same x and y. So since the y1 and y2 are different then to make it not a function, you have to make x1 and x2. To make it that b would have to be = to 5 and 0.
