I don't know how to graph this
Musya8 [376]
It's simple bud. First you have to distribute the 4/9.
y-2=4/9(x-3)
y-2=4/9x-1.33 (then leave the y by itself)
y=4/9x-1.33+2
y=4/9x+0.67 done!

The string of a kite is 120 metres long and it makes an angle of 60 degree
Afina-wow [57]

Answer:

103.92 m

Step-by-step explanation:

The kite is making right angle with the ground and its string is acting as hypotenuse of right triangle.

Let the height of the kite from the ground be h meters.

Therefore, by trigonometrical ratio:

\sin \theta \:  =  \frac{height \: of \: the \: kite}{length \: of \: the \: string}  \\  \\  \sin 60 \degree \:  = \frac{h}{120}  \\  \\  \frac{ \sqrt{3} }{2}  =  \frac{h}{120}  \\  \\ h =  \frac{ \sqrt{3} }{2}  \times 120 \\  \\ h =  \sqrt{3}  \times 60 \\  \\ h = 1.732 \times 60 \\  \\ h = 103.92 \: m \\

Thus, the height of the kite from the ground is 103.92 meters.

What is the smallest odd number with four different prime factors?
nevsk [136]
Obviously the smallest odd number we are looking for will have the SMALLEST four prime factors. 

The smallest four prime numbers are 2,3,5,7. The lowest multiple of this is 2*3*5*7 = 210 But this is an even number! 

So let's remove 2, and use the next prime number: 3,5,7,11. The lowest multiple of these is 3*5*7*11 = 1155.
