Answer:

x and y do not show direct variation.  

Step-by-step explanation:

The formula for direct variation is

y = kx     Divide each side by y

k = y/x

k should have the same value for every point except, of course, (0,0)

For the first point,

k = 2/(-1) = -2

For the third point,

k = 2/1 = 2

The values of k are different, so x and y <em>do not</em> show direct variation.

PLS Help Asap! i will award brainliest On her way to her grandmother's house, Jackie traveled three times as many miles by train
nirvana33 [79]

Answer:

24 miles.

Step-by-step explanation:

Jackie traveled four times as many miles by bus as by foot. This means that the number of miles travelled by bus is 4 units, and the number of miles travelled by foot is 1 unit.

Jackie traveled three times as many miles by train as by bus. We know that the number of miles travelled by bus is 4 units, so the number of miles travelled by train is 4\times3=12 units.

Total number of units: 12units+4units+1unit=17units

17units=34

Divide 17:

1 unit=2

The number of miles travelled by train is 12 units:

12units=2\times 12=24

She travelled 24 miles by train.

So sine of complementary angle also has same value as cos 42.
So sin 58 ~ 0.743
