Need math . match the y-coordinates with their corresponding pairs of x-coordinates on the unit circle.

No. 1 of tiles goes to No. 3 of pairs

No. 2 of tiles goes to No. 4 of pairs

No. 3 of tiles goes to No. 2 of pairs

No. 4 of tiles goes to No. 1 of pairs

Step-by-step explanation:

We are given the y co-ordinates in the box named 'TILES' and have to match the corresponding x co-ordinates from the box named "PAIRS' such that they satisfy the unit circle.

i.e. the pair (x,y) satisfies .

Now, we substitute the values of 'x' and 'y' provided in 'TILES' and 'PAIRS' correspondingly in the above equation of the unit circle.

We get that, the following co-ordinates form the pairs for the unit circle.

i.e. x = ± and y =

x = ± and y =

x = ± and y =

x = ± and y =

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
